The Complete Guide to Tiling in Centurion Homes
Professional tiling means bonding tile to a substrate with the correct adhesive, spacing, and — for wet areas — waterproofing beneath it, so the finished surface stays sound for years rather than failing within months. This guide covers what it actually costs, how many tiles to buy, why tiles crack or lift, which tile suits which room, and how to spot a corner-cutting quote before it's installed — with five free calculators built to answer each question with your own numbers.
The five questions this guide actually answers
This guide is built around the five questions Centurion homeowners are genuinely trying to answer when they search for tiling information — each one gets its own section below, with a free tool built specifically to answer it using your own numbers.
- What will this actually cost? — tiling cost splits into three near-equal components that most quotes bundle into one number.
- How many tiles do I need? — getting this wrong is expensive in both directions.
- Why are my tiles cracking, hollow, or lifting? — tiling failures are uniquely deferred, surfacing months after the original job.
- Which tile should I actually buy? — the trade-offs between ceramic, porcelain, and natural stone rarely map to how people actually use their homes.
- How do I choose a tiler I can trust? — a bad tiling job's flaws are frequently invisible until months after handover.

What does tiling actually cost — and why do quotes vary so much?
This is the dominant search in this category, and the confusion is structural, not accidental. Labour-only rates run roughly R80 to R350 per square metre depending on complexity, while all-in supply-and-fit spans R200 to R880 per square metre, and some sources quote ranges as wide as R230 to R1,850 per square metre once premium tiles and complex layouts are factored in.
Unlike painting or carpentry, tiling cost genuinely splits into three near-equal components — tiles, adhesive/grout/waterproofing materials, and labour. Most quotes bundle all three into one number, so comparing a "R300/m²" quote against a "R150/m²" quote tells you nothing about whether one includes waterproofing and the other doesn't, without asking directly. The calculator below breaks every quote into these three parts.
| Job | Typical cost |
|---|---|
| Labour only | R80 – R350/m² |
| All-in supply and fit | R200 – R880/m² |
| Bathroom (5-10m²), total | R7,500 – R25,000 |
| Full 3-bed home floor tiling | R20,000 – R50,000 |

What's actually driving your tiling quote?
See your cost broken into tiles, materials, and labour separately — so you can tell exactly what's driving a quote up or down, instead of comparing one bundled number against another.
Tile tier
Worked example 1
A porcelain bathroom floor
You're tiling an 8m² bathroom floor in porcelain and want to understand what's driving the total cost, not just see one number.
What to enter
- Area: 8m²
- Room type: Wet area (bathroom, shower, splashback)
- Tile tier: Porcelain
What you'll see
- Tiles: R1,200 – R4,000
- Adhesive: R400 – R1,200, Grout: R240 – R640
- Waterproofing (mandatory for wet areas): R560 – R1,200
- Labour: R800 – R2,800
- Estimated total: roughly R3,200 – R9,840
Why this matters: Waterproofing alone adds up to R1,200 to this job — money that a bundled quote might hide entirely. If a competing quote for the same bathroom comes in dramatically lower, this breakdown tells you exactly which line item to ask about first.
Worked example 2
A ground-level outdoor patio
You're tiling a 20m² ground-level patio in porcelain and want to know whether waterproofing should be part of the quote.
What to enter
- Area: 20m²
- Room type: Outdoor (patio, deck)
- Elevated deck/balcony checkbox: unchecked (this is a ground-level patio)
- Tile tier: Porcelain
What you'll see
- Tiles: R3,000 – R10,000
- Adhesive: R1,000 – R3,000, Grout: R600 – R1,600
- No waterproofing line item — ground-level patios don’t need a membrane
- Labour: R1,800 – R6,000
- Estimated total: roughly R6,400 – R20,600
Why this matters: Notice there's no waterproofing cost here, unlike the bathroom example — this tool doesn't add a cost that doesn't apply to your actual job. If a quote for a ground-level patio includes a waterproofing line item, ask why; if it's an elevated deck over a living space, that's a different story and the checkbox above should be ticked.
Bathroom and wet-area tiling: the compliance question most quotes skip
Bathroom tiling is where the biggest, most consequential corner gets cut, because the corner-cutting is completely invisible once the tiles go down. Waterproofing beneath bathroom and shower tiles isn't a nice-to-have — it's a genuine compliance requirement under SANS 10400 Part P (damp-proofing) working alongside SANS 10252 (sanitary installations), which specifies that waterproofing must extend up shower walls to at least 1.8 metres or full ceiling height, not just across the floor.
A quote that doesn't explicitly name waterproofing as a line item, or only waterproofs the floor and not the walls within the shower zone, is cutting a corner that won't show up until water starts finding its way through — often 12 to 24 months later, well after the original tiler has moved on. This is exactly why the Contractor Quote Scope Checklist further down this page treats waterproofing as a critical item for any wet-area job.
Bathroom tiling quick reference
- Waterproofing adds roughly R70 – R150/m² on top of standard tiling costs
- Labour for wet areas runs R100 – R350/m², higher than dry-area work due to extra cutting and waterproofing-adjacent prep
- Minimum slip rating for a shower floor: R11 — see the Tile Suitability Matcher below for the full picture
- A standard 5-10m² bathroom typically costs R7,500 – R25,000 in total
Use the All-In Tiling Cost Estimator above with "Wet area" selected for a figure that correctly includes waterproofing, and the Tile Suitability Matcher below to confirm the right tile and slip rating for your specific bathroom layout.
Outdoor tiling: the mistake that only shows up when it rains
A beautiful indoor porcelain tile installed on an outdoor patio can become a genuine safety hazard the first time it gets wet — almost nobody searching "which tile should I buy" knows to ask about slip rating, and it's the single most preventable outdoor tiling mistake. South Africa uses the R-rating (oil-wet ramp test) slip scale, and outdoor areas specifically need an R11-R12 rating, well above what most indoor tiles are rated for.
Frost and UV resistance matter too, even in Gauteng's relatively mild climate — an indoor-only tile, adhesive, or grout can degrade outdoors in ways that never show up inside. Waterproofing is a different story outdoors than in a bathroom, though: a ground-level patio generally doesn't need a waterproofing membrane at all, since water simply drains into the soil beneath it. An elevated deck or balcony over a living space is the exception — that genuinely does need waterproofing, similar to a wet-area floor.
Correct fall and drainage during installation matters more for a ground-level patio than waterproofing does — pooling water on an improperly sloped patio is a more common outdoor tiling complaint than any waterproofing failure.
How many tiles do I actually need?
A very practical, high-intent question from people who've already chosen a tile and are trying to work out how many boxes to buy. Getting it wrong is expensive in both directions: under-ordering risks a dye-lot mismatch on a second trip to the supplier — tile colour and shade vary between production runs, so a "matching" tile bought weeks later often visibly doesn't match — while over-ordering wastes money on opened stock that usually can't be returned.
Wastage allowances aren't intuitive either. A straight-lay pattern needs roughly 10% extra, but diagonal layouts need closer to 15%, and herringbone can need 18-20%, since every wall produces diagonal or angled cuts that are harder to reuse than a straight lay's rectangular offcuts. Rooms with lots of cuts around fittings — a small bathroom, an L-shaped kitchen — need a further 2-5% on top of that.

How many tiles do I actually need?
Room size, tile size, and layout pattern — get the correct box count for your specific job, including the right wastage allowance for that pattern, not a flat 10% guess.
Layout pattern
Room complexity
Worked example 1
A straightforward small bathroom
You're tiling a 2.5m x 2m bathroom floor with 300 x 300mm tiles in a straight layout, and the room has the usual toilet, basin, and other fittings to cut around.
What to enter
- Room: 2.5m x 2m (5m²)
- Tile size: 300 x 300mm
- Layout pattern: Straight
- Room complexity: Heavy cutting (small bathroom, many fittings)
What you'll see
- Total wastage applied: 15% (10% straight-lay base + 5% heavy-cutting complexity)
- 64 tiles needed for the job
- 7 boxes recommended (6 for the job, plus 1 spare from the same batch)
Why this matters: The heavy-cutting complexity modifier adds a real 5% on top of the already-standard 10% for a small, fitting-dense room like this — a flat 10% guess would have left you short by several tiles once all the cuts around the toilet and basin are accounted for.
Worked example 2
A large-format living room, diagonal layout
You're tiling a 6m x 5m living room (30m²) with 600 x 600mm large-format tiles laid diagonally for a more dramatic look.
What to enter
- Room: 6m x 5m (30m²)
- Tile size: 600 x 600mm (large format)
- Layout pattern: Diagonal
- Room complexity: Simple (rectangular room, no obstacles)
What you'll see
- Total wastage applied: 17% (15% diagonal base + 2% large-format uplift)
- 98 tiles needed for the job
- 26 boxes recommended (25 for the job, plus 1 spare from the same batch)
Why this matters: Two things stack here that a simpler calculator would miss: the diagonal pattern's higher base wastage, and the extra 2% for large-format tiles specifically, since breakage risk roughly doubles when handling bigger, heavier tiles. Skipping either adjustment on a 30m² room would leave you noticeably short.
Ceramic vs. porcelain vs. natural stone — and the slip rating almost nobody asks about
A material-decision question from people who've settled on tiling as the flooring choice but are stuck on which tile to actually buy. The trade-offs are rarely explained in terms that map to how people actually use their homes.
| Tile type | Typical cost | Best suited to |
|---|---|---|
| Ceramic | R80 – R250/m² | Low-traffic indoor areas — softer and more prone to chipping than porcelain. |
| Porcelain | R150 – R500/m² | High-traffic and wet areas — much lower water absorption than ceramic. |
| Natural stone | R400 – R1,500/m² | Feature areas where a premium look justifies specialist installation and ongoing sealing. |
On top of material choice, there's a slip-rating dimension almost nobody asks about. South Africa uses the R-rating (oil-wet ramp test) system — the same scale used across Europe, not the different Australian P-rating scale. A dry indoor floor only needs R9; a bathroom or kitchen floor needs R10-R11; a shower floor needs R11 minimum; outdoor areas specifically need R11-R12; and pool surrounds need the highest rating band, R12-R13.
Tile Suitability Matcher
Pick the area you're tiling and, if you've got a tile in mind, check whether it's actually suitable — including the slip rating and waterproofing requirement for that specific area.
Is this tile actually right for where I want to use it?
Pick the area you're tiling and, if you've already got a tile in mind, check whether it's actually suitable — including the slip rating and waterproofing most people never think to ask about.
Worked example 1
Ceramic tile for a shower floor
You've found an attractive ceramic tile on sale and are wondering whether it's suitable for your shower floor.
What to enter
- Area: Shower floor
- Tile type you’re considering: Ceramic
What you'll see
- Compatibility verdict: Risky choice
- Recommended instead: Porcelain in a smaller format, R11 minimum slip rating
- Waterproofing: Mandatory, extending up walls to 1.8m or ceiling height
Why this matters: This is exactly the mistake the research identified — a tile that looks fine in the shop often isn\u2019t rated for a wet, frequently-barefoot area like a shower floor. The tool catches this before you buy, not after you've already paid for tiles that need to be returned or replaced.
Worked example 2
Porcelain for a ground-level patio
You're considering a full-body porcelain tile, specifically marketed for outdoor use, for a ground-level patio.
What to enter
- Area: Outdoor patio (ground level)
- Tile type you’re considering: Porcelain
What you'll see
- Compatibility verdict: Good match
- Slip rating needed: R11-R12
- Waterproofing: Not required for a ground-level patio
Why this matters: Porcelain gets a straightforward good match here, but the tool still flags the one thing to confirm: that this specific product actually carries the R11-R12 rating, since not every porcelain tile marketed as 'outdoor suitable' is rated the same way.
Why are my tiles cracking, hollow, or lifting?
An extremely common and high-anxiety search, usually triggered months or even years after installation when something starts going visibly wrong. Most homeowners don't realise that a hollow sound when tapping a tile — a dull "thud" instead of a sharp "tink" — is an early warning sign of adhesive failure, not a cosmetic quirk to ignore. The progression from hollow-sounding to fully cracked typically takes only 3 to 12 months once it starts, because every footstep flexes the unsupported tile until it fails.
The frustrating part is that the underlying causes are almost always installation shortcuts that were invisible at the time: spot-fixing adhesive in blobs instead of a full bed, skipping back-buttering on large-format tiles, using the wrong adhesive for the tile or substrate, or missing expansion joints entirely. None of this shows up on the day the tiler finishes — it shows up 6, 12, or 24 months later, by which point the original tiler is long gone and there's no paper trail proving the workmanship was at fault.
Tile Failure Diagnostic Tool
Answer two quick questions about what you're seeing or hearing, and where, and this tool points you toward the likely cause and whether it's a simple fix or something more serious.
What's actually wrong with my tiles?
A hollow sound today is often a crack in 3 to 12 months. Answer two quick questions and this tool points you toward the likely cause and whether it's a simple fix or something more serious.
Where is the problem?
What are you seeing or hearing? (select all that apply)
Worked example 1
A hollow sound in a dry-area floor
You've noticed a dull, drum-like sound when tapping a few tiles in your living room floor, though nothing looks visibly wrong yet.
What to enter
- Location: Dry area (living room, bedroom, hallway)
- Symptoms: Hollow or drum-like sound when tapped
What you'll see
- Likely cause: Adhesive failure
- Fix level: Moderate — affected tiles typically need removal and re-bedding
- Explanation: voids beneath the tile from uneven adhesive coverage during installation
Why this matters: Catching this at the hollow-sound stage, rather than waiting for a visible crack, is exactly the early-warning value this tool is built around — the progression from hollow to cracked typically takes only 3 to 12 months, so acting now is genuinely cheaper and less disruptive than waiting.
Worked example 2
Water stains and a musty smell in a bathroom
You've noticed a faint musty smell near your bathroom floor along with a water stain on the ceiling of the room below.
What to enter
- Location: Wet area (bathroom, shower)
- Symptoms: Water stains or damp patches appearing nearby
- Symptoms: A musty smell near the tiled area
What you'll see
- A wet-area water flag shown prominently above the main diagnosis
- Likely cause: Water penetrating behind the waterproofing
- Fix level: Urgent — get a professional assessment promptly
Why this matters: This is the tool's most serious flag, and deliberately so — water behind failed wet-area waterproofing can cause structural damage to the subfloor or the ceiling below, which is a materially bigger problem than the tiles themselves. This is not a re-grout job.
How do I choose a tiler and avoid a bad job?
A trust-and-verification question, often triggered by hearing about — or living through — a tiling job that looked fine on day one and fell apart within a year. Unlike a burst pipe, a bad tiling job's flaws are frequently invisible at handover. Hollow spots, missing expansion joints, and inadequate waterproofing don't show up until months later, by which point proving the work was substandard, versus "just wear and tear," is difficult without a professional inspection.
Homeowners want to know what to ask before the job starts — does the quote include a workmanship guarantee, is waterproofing to the correct standard explicitly included, will a tile-levelling system be used for large-format tiles — but this is exactly the kind of technical checklist that never gets asked because the vocabulary to ask it in isn't common knowledge. The tool below generates that checklist for your specific job.
Contractor Quote Scope Checklist Generator
Answer a few questions about your job and get a personalised checklist to hand to any tiler before you sign — with items escalated to critical based on your actual room type, tile format, and substrate.
Build your tiling quote scope checklist
Answer a few questions about your job and get a checklist tailored to it — hand it to any tiler before you sign, or use it to check a quote you've already received.
Worked example 1
A standard bathroom, new substrate
You're getting a new bathroom floor and wall tiled on a bare concrete substrate, using a standard-format tile.
What to enter
- Room type: Wet area (bathroom, shower)
- Tile format: Standard format (under 600mm)
- Substrate: New substrate (bare concrete or screed)
What you'll see
- 10 checklist items generated
- Waterproofing flagged Critical, extending up walls to 1.8m or ceiling height
- Slip rating flagged Critical for the wet area
- No large-format or tile-on-tile items, since neither applies to this job
Why this matters: The tool doesn\u2019t generate irrelevant items just to look thorough — it only escalates what actually matters for this specific job. For a standard bathroom on a fresh substrate, waterproofing and slip rating are the two items worth the most scrutiny in the quote.
Worked example 2
A large-format outdoor deck, tiling over existing tile
You're tiling a large-format porcelain outdoor deck directly over existing, sound tile.
What to enter
- Room type: Outdoor (patio, deck)
- Tile format: Large format (600mm and above)
- Substrate: Tiling over existing tile
What you'll see
- 13 checklist items generated
- Slip rating flagged Critical (outdoor area)
- Tile-levelling system and back-buttering both flagged Critical (large-format tile)
- Tile-on-tile surface preparation and compatible adhesive flagged Critical (existing tile substrate)
Why this matters: This job stacks three separate risk factors — outdoor, large-format, and tile-on-tile — and the checklist grows to reflect all three rather than giving a generic list. A quote for this specific combination that doesn\u2019t address all four critical items is missing meaningful scope, not just minor detail.
Putting it all together: your personalised decision plan
You've now seen how to cost your job across its three real components, work out exactly how many tiles to buy, match the right tile to the right room, diagnose whether an existing problem needs urgent attention, and check a quote for complete scope. This last tool ties all of that together into a single, ordered action plan based on your actual answers — including a hard stop if you're dealing with an existing tile failure, since no amount of quote-comparing matters if the underlying cause hasn't been diagnosed first.
Your personalised tiling decision plan
This is a general estimate and general guidance only, not a binding quote or professional diagnosis. Actual pricing and any structural findings are confirmed by the professionals you engage.
Tile tier (rough guess is fine)
Where your tiling budget actually goes
Unlike painting, tiling cost doesn't split neatly into one dominant category — tiles, materials, and labour sit much closer to equal thirds, which is exactly why bundled quotes are so hard to compare. Knowing roughly what each third should cost helps you spot when one of them has been quietly left out.
Tiles
R80 – R1,500/m² depending on tier. The most visible cost, and the one most homeowners focus on — even though it's often not the largest of the three components.
Materials
Adhesive (R50-R150/m²), grout (R30-R80/m²), and waterproofing where needed (R70-R150/m²) — easy to underestimate since they're rarely itemised separately.
Labour
R80 – R350/m² depending on complexity. This is where corner-cutting most often hides — full-bed adhesive application takes longer than spot-fixing, but you can't see the difference once the tile is down.
How TradesHub verifies tilers, in the absence of a registration body
Tiling has no equivalent to IOPSA for plumbers, but wet-area work is still governed by a real national standard — SANS 10400 Part P and SANS 10252. Trust on this platform is built through a rigorous process suited to that reality, not skipped because no registration body exists.
Identity verification
Every tiler on TradesHub confirms their real identity with documentation before their profile goes live — the same baseline requirement applied across every trade on the platform.
Portfolio review
Tilers provide photographic evidence of completed work before approval — since tiling failures are invisible at handover, a documented history of past jobs that have held up over time is a genuinely meaningful signal.
Verified reviews only
Reviews are tied to real, confirmed bookings through the platform — not open, unverified submissions.
Visible workmanship guarantees
Because tiling problems often only surface long after the original job, a workmanship guarantee visible on a profile matters more here than in most other trades — it's a concrete signal that a tiler stands behind work that hasn't failed yet.
What happens when you book a tiler through TradesHub
- Browse or call. Compare verified tiler profiles online, or call the TradesHub line to be matched by phone.
- Compare real profiles. Check portfolios, verified reviews, and any stated workmanship guarantee before reaching out.
- Request a quote. Share your job details directly — area, room type, tile format, and substrate all affect the accuracy of the quote you'll receive.
- Run it through the tools on this page. Check the cost breakdown, confirm tile suitability, and generate a Scope Checklist for anything you're not sure is included.
- Book and confirm. Confirm the booking with scope, price, timeline, and guarantee period already agreed in writing.
How to measure your room for an accurate tile count
The Tile Quantity Calculator on this page is only as accurate as the numbers you put into it.
- Measure length and width at floor level, rounding to the nearest 0.1m rather than guessing.
- Confirm your tile's exact size in millimetres — don't assume a "600mm" tile is exactly 600mm; check the product specification.
- Check the tiles-per-box figure on your specific product rather than assuming a standard number — packaging varies by brand and range.
- Be honest about room complexity — an L-shaped room, an island, or multiple fittings genuinely needs the higher wastage tier, not the optimistic one.
- Buy everything from the same batch, including the spare box — this is the single detail most likely to be forgotten and most expensive to fix later.
Common mistakes homeowners make when hiring a tiler
Choosing the cheapest quote without checking the adhesive method
Spot-fixing adhesive in blobs is faster and cheaper than a full bed, and completely invisible once the tile is down. Confirm full-bed application in writing — this single item prevents the most common tiling failure in this category.
Ignoring a hollow sound because nothing looks wrong yet
A hollow sound is an early warning, not a false alarm — it typically progresses to a visible crack within 3 to 12 months. Use the Tile Failure Diagnostic tool the moment you notice it, not after it's already cracked.
Choosing a tile before checking its slip rating
Falling in love with a tile's look before confirming it's rated for the intended area is how beautiful indoor tiles end up as safety hazards outdoors or in showers. Check the Tile Suitability Matcher before you buy, not after.
Not asking about a workmanship guarantee
Because tiling failures are invisible at handover and surface months later, a workmanship guarantee is one of the few protections that actually covers the specific risk this category carries. No stated guarantee should be treated as a real gap in the quote.
Underestimating tile quantity and buying from a different batch later
A second trip to the supplier for "the same tile" often isn't the same tile — dye lots vary between production runs. Buy enough the first time, from one batch, including a spare box.
Assuming ground-level outdoor tiling needs the same waterproofing as a bathroom
Ground-level patios generally don't need a waterproofing membrane — proper drainage fall matters more. Paying for waterproofing you don't need is as much a quote-scope issue as missing waterproofing you do need.
Tiling considerations by dwelling type
Freestanding house
The most straightforward case — every decision, including outdoor patio tiling, is yours to make directly with your tiler with no third-party approval needed.
Townhouse / complex
Interior tiling is usually your own decision, but visible exterior tiling changes — a patio facing a common area, for instance — may need body corporate or HOA sign-off first. Check your complex's rules before booking.
Flat / apartment
Interior tiling within your own unit is typically your call. Balconies and any externally visible surfaces usually fall under body corporate rules, similar to a townhouse complex.
Glossary
Full-bed adhesive
Adhesive applied across the entire back of a tile and the substrate, as opposed to "spot-fixing" in a few blobs — the single biggest factor in preventing hollow spots and later cracking.
Back-buttering
Applying adhesive directly to the back of the tile itself, in addition to the substrate — essential for large-format tiles to avoid voids beneath them.
Lippage
Uneven, stepped edges between adjacent tiles, usually caused by skipping a tile-levelling system — more than cosmetic, it's a genuine trip hazard.
Tile-levelling system
Clips and wedges used during installation to hold adjacent tiles at the same height while the adhesive cures, preventing lippage — especially important for large-format tiles.
Expansion / movement joint
A flexible gap, filled with sealant rather than grout, that allows a tiled surface to absorb thermal or structural movement without cracking.
R-rating
The slip-resistance rating scale used in South Africa and Europe (oil-wet ramp test), ranging from R9 (dry indoor) to R13 (pool surrounds and demanding wet-outdoor use).
Dye lot
A single production batch of tiles. Colour and shade can vary between different dye lots of the "same" tile, which is why buying extra from one batch upfront matters.
Substrate
The surface tiles are bonded to — bare concrete, screed, existing tile, or timber/plywood — each requiring a different adhesive approach.
Tile-on-tile
Installing new tile directly over sound existing tile, using a compatible polymer-modified adhesive rather than removing the original layer.
SANS 10400 / SANS 10252
The South African national standards governing damp-proofing (Part P of SANS 10400) and sanitary installations (SANS 10252), which together specify wet-area waterproofing requirements.
Tiling across Centurion's suburbs
Tiling needs vary by suburb — older housing stock tends to bring ageing waterproofing and outdated adhesive standards, while newer estate homes are more often first-time additions or upgrades.
Irene
A mix of older smallholdings and newer estate homes — older bathrooms here more often need a full re-waterproof.
Lyttelton
Established housing stock where original tiling is often decades old, with dated adhesive standards behind it.
Wierdapark
A broad mix of freestanding houses and townhouse complexes, with body corporate rules sometimes applying to exterior changes.
Highveld
Newer estate development — most tiling jobs here are additions or upgrades rather than failure repairs.
Hennopspark
Mixed residential and light industrial — tilers here often handle both home bathrooms and small commercial floor jobs.
Thatchfield
A newer estate area where outdoor patio tiling is a common upgrade request.
Kosmosdal
Growing residential node with a mix of new-build homes and older townhouse stock needing re-tiling.
Eldoraigne
Established suburb with older housing stock — similar profile to Lyttelton for ageing wet-area waterproofing.
What Centurion homeowners say
“We got three quotes for our bathroom and they varied by almost R10,000. Turned out the cheapest one had no waterproofing line item at all. The scope checklist on this site showed me exactly what to ask before signing anything.”

Timing outdoor tiling around Gauteng's weather
Outdoor tiling depends on adhesive and grout curing properly, and Gauteng's climate has a genuine best and worst season for this kind of work.
Good conditions
- Dry, mild weather — autumn and spring are generally reliable
- No rain forecast for at least 48-72 hours after grouting
- Moderate temperatures, avoiding both extreme heat and cold overnight temperatures
Conditions to avoid
- Gauteng's summer thunderstorm season, where unexpected rain can affect curing adhesive
- Very cold winter nights, which can slow or affect adhesive and grout curing
- Extreme midday heat, which can cause adhesive to set unevenly
This mostly affects scheduling rather than cost — a professional tiler will typically build weather delays into an outdoor project timeline, which is another reason a quote should state an estimated completion date rather than leaving it open-ended.
Why DIY is a less common consideration for tiling
Unlike painting, this guide doesn't include a DIY-versus-professional comparison, and that's a deliberate reflection of the trade rather than an oversight. Tiling well requires specific equipment most homeowners don't own — a wet tile saw for clean cuts, notched trowels sized correctly for the tile, and tile-levelling clips for anything beyond a small format — plus the specific technique of achieving even adhesive coverage across an entire tile bed, which is exactly the skill gap behind most of the failures covered earlier on this page.
Wet-area work adds a compliance dimension DIY genuinely struggles with: waterproofing done incorrectly is invisible until it fails, and by then the damage may extend beyond the tiles themselves. A small, low-stakes dry-area patch job is a reasonable candidate for a confident DIYer; a bathroom, a large-format floor, or anything outdoors is generally better handled by a professional from the outset.
Grout colour and ongoing maintenance
Grout choice affects more than looks. Light grout in a high-traffic or wet area shows dirt and mildew far sooner than a mid-tone or dark grout, and cement-based grout is more porous than epoxy, meaning it stains and absorbs moisture more readily — a genuine consideration for kitchen floors and shower recesses, not just an aesthetic preference.
Sealing grout periodically (roughly once a year for cement-based grout in wet areas) helps maintain its water resistance over time. Natural stone tiles need the same sealing treatment on the tile surface itself, not just the grout — this is the ongoing maintenance cost the Tile Tier comparison earlier on this page references, and it's worth budgeting for rather than discovering after the fact.
Tiling FAQs — Centurion
How much does tiling cost in Centurion?
Labour-only rates run roughly R80 to R350 per square metre, while all-in supply-and-fit (tiles, materials, and labour) spans R200 to R880 per square metre. A standard 5-10m² bathroom typically costs R7,500 to R25,000 total, and a full 3-bedroom home’s floor tiling can run R20,000 to R50,000. Use the All-In Tiling Cost Estimator on this page for a figure broken into its three real components rather than one bundled number.
Why do tiling quotes vary so much for what sounds like the same job?
Because tiling cost genuinely splits into three near-equal components — tiles, adhesive/grout/waterproofing materials, and labour — and most quotes bundle all three into one number. A "R300/m²" quote and a "R150/m²" quote may differ simply because one includes waterproofing and the other doesn’t, with no way to tell without asking directly.
How many tiles do I need for my project?
Beyond the bare room area, add a wastage allowance: roughly 10% for a straight-lay pattern, 15% for diagonal, and 18-20% for herringbone, plus 2-5% more for rooms with alcoves or heavy cutting. Use the Tile Quantity & Wastage Calculator on this page for an exact box count based on your room and tile size.
Why should I buy extra tiles and keep them unused?
Tile colour and shade vary between production batches (dye lots), so a "matching" tile bought weeks or months later from a different batch often visibly doesn’t match. Buying one extra box from the same batch as your original order, and keeping it sealed and stored, protects you against needing an unmatched repair later.
Is a tiler in Centurion required to be registered with a professional body?
No — there is no formal registration body certifying individual tilers in South Africa. However, wet-area tiling work is subject to a real national standard (SANS 10400 Part P and SANS 10252) governing waterproofing compliance. Trust comes from verified identity, a documented portfolio, genuine reviews, and a visible workmanship guarantee.
What does a hollow sound in my tiles actually mean?
A hollow, drum-like sound instead of a solid "tink" when tapped is an early warning sign of adhesive failure — voids beneath the tile from uneven adhesive coverage during installation. Left unaddressed, it typically progresses to a visible crack within 3 to 12 months as normal foot traffic flexes the unsupported tile.
Why is my grout cracking even though the tiles look fine?
This is the classic sign of a missing expansion or movement joint. Grout is more rigid than the tile bed, so ordinary thermal or structural movement cracks the grout first when there’s no flexible joint to absorb it. This is often a genuinely simple fix — re-grouting and adding a proper movement joint — rather than a full re-tile.
Is a hollow tile always a serious problem?
It’s always worth acting on, but the fix level depends on the cause and how much has spread. An isolated hollow tile caught early may just need re-bedding; widespread hollow sounds across more than 20% of a floor generally warrants a professional assessment before choosing a fix.
What should I do if I notice water stains near bathroom tiles?
Treat this as urgent. Water penetrating behind failed wet-area waterproofing can cause structural damage to the subfloor or the ceiling below if left unaddressed — this is a materially more serious problem than the tiles themselves. Use the Tile Failure Diagnostic tool on this page, and get a professional assessment promptly rather than just re-grouting the visible symptom.
What’s the difference between ceramic, porcelain, and natural stone tiles?
Ceramic (R80-R250/m²) suits low-traffic indoor areas but chips more easily. Porcelain (R150-R500/m²) has much lower water absorption and handles high-traffic and wet areas well. Natural stone (R400-R1,500/m²) offers a premium look but needs specialist installation and ongoing sealing maintenance the other two don’t require.
What slip rating do I need for my tiles?
South Africa uses the R-rating scale. Dry indoor floors need only R9. Bathroom and kitchen floors need R10-R11. Shower floors need R11 minimum. Outdoor areas need R11-R12. Pool surrounds need the highest band, R12-R13. Use the Tile Suitability Matcher on this page to confirm the right rating for your specific area.
Can I install an indoor tile outdoors if I like the look?
Generally no, without checking carefully first. Many indoor tiles, including most ceramic, aren’t rated for the R11-R12 slip resistance outdoor areas need, and may not be frost- or UV-resistant either. Confirm the specific product is rated for exterior use before installing it outdoors — a beautiful indoor tile on a wet patio can become a genuine safety hazard.
What should a proper tiling quote include?
A complete quote should specify full-bed adhesive application (not spot-fixing), the adhesive type matched to your tile and substrate, expansion joints, grout type, and — for wet areas — SANS-compliant waterproofing extending up walls to at least 1.8m. For large-format tiles, it should also specify a tile-levelling system and back-buttering. Use the Contractor Quote Scope Checklist on this page to generate a personalised version of this list.
Is waterproofing really necessary under bathroom tiles?
Yes — this is a compliance requirement under SANS 10400 Part P and SANS 10252, not an optional upgrade. Waterproofing must extend up shower walls to at least 1.8 metres or full ceiling height, not just cover the floor. Skipping or under-scoping this is one of the most serious corners a cheap quote can cut.
Does an outdoor patio need waterproofing under the tiles?
Generally no, if it’s a ground-level patio — water simply drains into the soil beneath it, and correct drainage fall during installation matters more than a membrane. An elevated deck or balcony over a living space is the exception and does need waterproofing, similar to a wet-area floor.
Can I tile directly over my existing tiles?
Often yes, if the existing tile is sound and firmly bonded, using a compatible polymer-modified adhesive and proper surface preparation. Most tile-on-tile failures trace back to skipping this preparation step, not the method itself being flawed — confirm your tiler is using a tile-on-tile-rated adhesive, not a standard one.
What’s special about installing large-format tiles?
Tiles 600mm and above need a tile-levelling system to prevent lippage (uneven edges) and back-buttering to avoid voids beneath the tile that lead to hollow sounds and eventual cracking. They also carry a slightly higher wastage allowance during ordering due to increased breakage risk when handling larger, heavier tiles.
Can I get a tiler quickly for a small repair job in Centurion?
Yes — many TradesHub tilers take on smaller repair and re-grout jobs alongside full tiling projects. Availability and minimum job size vary by professional, so check individual profiles or use the phone booking line for same-week availability.
How long does grout need to cure before I can use the room?
Timelines vary by product, but as a general guide, tiles typically shouldn’t bear normal foot traffic for at least 24 hours after laying, and grout commonly needs 48 to 72 hours before the area can get wet, such as using a shower. Ask your tiler for the specific timeline for the products used on your job rather than assuming a standard figure.
Does TradesHub sell tiles or recommend a specific supplier?
No — TradesHub is a booking platform connecting homeowners with independent tiling professionals. Material and pricing information on this page is provided for educational context only, not as a recommendation or paid placement, and the choice of tile supplier is between you and the tiler you book.
What’s the fastest way to check if a tiling quote is trustworthy?
Run it through the tools on this page: the All-In Cost Estimator to see whether the price reflects a realistic breakdown of tiles, materials, and labour, and the Contractor Quote Scope Checklist to confirm full-bed adhesive, expansion joints, correct waterproofing, and a workmanship guarantee are all specified in writing. A quote that passes both is a genuinely low-risk one to accept.
Can I supply my own tiles and just pay a tiler for labour?
Yes, this is common practice in South Africa. Confirm the exact quantity needed with your tiler beforehand — the Tile Quantity Calculator on this page can help — and agree the labour-only rate in writing before work starts, since labour-only rates (R80-R350/m²) are meaningfully lower than all-in quotes that include tiles and materials.
Why did my tiler recommend a decoupling membrane?
A decoupling membrane is sometimes used over substrates prone to minor movement or cracking, particularly for tile-on-tile installations or older concrete, to reduce the risk of that movement transferring up into the new tile layer. It’s an added material cost, but one that can prevent exactly the subfloor-movement-driven cracking covered in the Tile Failure Diagnostic tool above.
How do I know if my existing tiles are sound enough to tile over?
Do the tap test across the existing surface first — if a significant portion sounds hollow already, tiling over it will trap that problem rather than solve it, and the existing layer should be removed instead. A tiler experienced with tile-on-tile work should assess this before quoting, not after starting.
How often should grout be resealed?
Roughly once a year for cement-based grout in wet areas like bathrooms and kitchens, and less frequently for epoxy grout, which is inherently more water- and stain-resistant. Natural stone tiles need the tile surface itself resealed periodically too, not just the grout.
Is dark grout or light grout better for a bathroom?
Dark or mid-tone grout generally hides dirt and mildew for longer than light grout in wet, high-traffic areas like bathrooms and shower recesses. It’s a genuine maintenance consideration, not just a style choice — factor it in alongside the tile colour itself when deciding.

Find a verified tiler in CenturionWhen a re-tile isn't enough
Sometimes the Tile Failure Diagnostic points to a cause that needs more than a tiler can fix alone. Knowing who to call next avoids paying for a re-tile that was never going to solve the underlying problem.
| If the cause is | Who to call first | Then re-tile? |
|---|---|---|
| Adhesive failure (hollow sound) | A tiler, for removal and re-bedding | Yes, this is typically a tiling-only fix |
| Missing expansion joint (grout cracking) | A tiler, often just for a targeted re-grout | Often no full re-tile needed at all |
| Subfloor movement (structural) | A structural engineer or builder | Yes, once the movement issue is resolved |
| Water behind failed waterproofing | A waterproofing specialist, urgently | Yes, once waterproofing is properly redone |
Tiling before selling your home
Bathroom and kitchen tiling condition is one of the details buyers and their inspectors notice quickly, and unresolved tile problems can complicate a sale.
- A hollow sound or cracked grout discovered during a pre-sale inspection is far more likely to raise questions than the same issue found during a casual viewing — address it before listing, not after an offer is on the table.
- Neutral, popular tile choices in bathrooms and kitchens generally appeal to a wider range of buyers than bold or dated styles.
- If bathroom waterproofing is genuinely unknown or suspect, get it checked before a sale — an unresolved wet-area issue discovered during a buyer's inspection can delay or complicate a transaction significantly more than a straightforward repair handled in advance.
- Budget realistic lead time for tiling work ahead of a listing deadline — a rushed re-tile job is exactly the kind of job most likely to skip the prep steps that prevent early failure.
A note on wet floors during and after installation
Freshly laid tiles and curing grout can be genuinely slippery, and adhesive needs time to cure fully before a floor can safely bear normal foot traffic. Ask your tiler for a clear timeline on when the area is safe to walk on and when it can get wet — this is a straightforward question that a professional tiler should answer clearly and specifically for your job, not with a vague "give it a few days."
