How Much Does Bathroom Renovation Cost in Sydney 2026
A bathroom renovation in Sydney costs $10,000–$18,000 for a cosmetic refresh, $22,000–$38,000 for a mid-range full renovation, and $40,000–$55,000+ for a luxury fitout in 2026. A standard 6 m² Sydney bathroom, stripped back and redone to a mid-range standard, lands near $21,700 inc. GST.
If you're staring at cracked tiles, a dodgy exhaust fan and a shower screen that's seen better days, the gap between those numbers comes down to three things: size, finish level, and whether the plumbing moves. Nothing else shifts the total as much.
This guide breaks down the three price bands, walks through every line item you'll see on a quote, shows the actual rates a quote is built from, and gives you a realistic timeline.

Key takeaways
- A mid-range full bathroom renovation in Sydney costs $22,000–$38,000 inc. GST in 2026; a cosmetic refresh starts around $10,000.
- The single biggest saving available is keeping the existing layout — leaving the toilet, shower and vanity where they are cuts roughly $2,700 off a standard 6 m² job.
- Small bathrooms cost more per square metre, not less. A 3 m² ensuite works out near $5,900 per m²; a 9 m² family bathroom near $2,900 per m².
- Waterproofing is legally required in NSW under AS 3740 and adds about $1,900 inc. GST to a full renovation — it is never the line to trim.
- Expect 2–3 weeks on site, plus 2–6 weeks of planning and material lead times before anyone swings a hammer.

What does a bathroom renovation cost in Sydney in 2026?
Sydney bathroom renovations fall into three clear price bands in 2026: $10,000–$18,000 for a refresh, $22,000–$38,000 for a mid-range full renovation, and $40,000–$55,000+ for luxury. Not every reno is a gut-and-start-again job, and the band you're in is decided before you pick a single tile.
| Renovation level | Typical scope | Price range (inc. GST) |
|---|---|---|
| Budget refresh | New vanity, taps, mirror, paint, reseal shower — no layout changes | $10,000 – $18,000 |
| Mid-range full reno | Strip to bare walls, new waterproofing, tiling, fixtures, lighting, ventilation | $22,000 – $38,000 |
| Luxury / custom | Premium tiles, freestanding bath, frameless glass, underfloor heating, niche shelving, custom joinery | $40,000 – $55,000+ |
A standard 3 m × 2 m bathroom in a Sydney house will usually fall in the mid-range bracket. Ensuites are smaller but can cost just as much per square metre, because the waterproofing and plumbing minimums don't scale down.
How we got these numbers: the ranges above are built from estimates generated through Leadkit's own bathroom renovation calculator, using its current Australian default rates, then cross-checked against Sydney market rates. Leadkit builds the calculator — it's our tool, not neutral third-party data — but the rates underneath it are the real ones tradies quote from, and we've published them in full further down this page.
Material prices have largely stabilised after the post-COVID spike, but labour hasn't. Licensed waterproofers and tilers remain tight across the Inner West and Eastern Suburbs, which is why Sydney sits at the top of the national range rather than the middle. The Housing Industry Association tracks these trade-availability pressures if you want the industry view.
Important note: these are guide prices only. This is a price indication only. Your tradie will confirm the final price after assessing the job — every bathroom has its own surprises hiding behind the tiles.
What does each line item on a Sydney bathroom quote cost?
On a mid-range Sydney bathroom renovation, tiling ($3,500–$7,000) and plumbing ($2,500–$5,000) are the two biggest line items, together making up 40–50% of the total. Here's the full breakdown you should expect to see on any decent quote.
| Item | Cost range (inc. GST) |
|---|---|
| Demolition and strip-out | $1,500 – $3,000 |
| Plumbing rough-in | $2,500 – $5,000 |
| Waterproofing (membrane + certification) | $1,200 – $2,500 |
| Electrical (lighting, exhaust, heated towel rail) | $1,000 – $2,500 |
| Wall and floor tiling (supply + labour) | $3,500 – $7,000 |
| Vanity, basin and tapware | $1,200 – $4,000 |
| Toilet | $400 – $1,500 |
| Shower screen (semi-frameless or frameless) | $800 – $2,500 |
| Shower head, mixer and accessories | $300 – $1,200 |
| Painting and finishing | $500 – $1,200 |
| Skip bin and waste disposal | $400 – $800 |
| Project management / builder's margin | $1,500 – $3,500 |
If you're choosing large-format porcelain tiles (600x600 or bigger), expect the tiling labour to sit at the higher end — they're heavier, harder to cut, and need a flatter substrate. You can price that line on its own with the tiling quote calculator, or read the national breakdown in our guide to tiling cost per square metre.
Waterproofing is non-negotiable in NSW — it must comply with AS 3740, and you need a certificate of compliance before tiling starts. Cutting corners here is how you end up with water damage and a $20,000 rectification bill two years later. If you want to understand that trade separately, start with the waterproofing enquiry page or the waterproofing cost per square metre guide.
What rates is a bathroom renovation quote actually built from?
A bathroom quote is assembled from about eleven underlying rates, not one lump sum. These are the current default rates inside Leadkit's bathroom renovation calculator — the figures a tradie starts from before adjusting for their own costs.
| Quote component | Default rate (ex. GST) |
|---|---|
| Demolition and prep | $300 per m² of floor area |
| Tiling — supply and lay, budget tiles | $110 per m² of tiled area |
| Shower — supply and install | $2,500 |
| Bath — supply and install | $2,200 |
| Vanity — supply and install | $1,800 |
| Toilet — supply and install | $900 |
| Base plumbing | $2,500 |
| Base electrical | $1,500 |
| Waterproofing | $1,500 |
| Project management / margin | 15% of construction cost |
| Minimum job fee | $6,500 |
Two things in that table catch people out.
Tiled area is not floor area. With full-height wall tiles, the tiled area works out at roughly five times the floor size — a 6 m² bathroom means about 30 m² of tiling. That's why tile choice swings the total so hard: switching from budget ceramic to premium large-format or natural stone doubles the tiling rate and adds about $2,500 inc. GST to a standard job.
There's a floor under every quote. The $6,500 minimum job fee exists because mobilising five trades, a skip bin and a waterproofing certificate costs the same whether the room is tiny or not. No Sydney builder is doing a compliant wet-area renovation for $4,000, and a quote that low is telling you something's missing.
Across the bathroom renovation quotes generated through Leadkit, the line homeowners consistently underestimate isn't the tiles — it's the 15% project management margin plus GST sitting on top of everything else. On a $19,000 build cost, that's roughly $4,500 that never appears in a Pinterest budget.

What pushes a Sydney bathroom renovation over budget?
The four biggest cost drivers are moving plumbing, premium tiles, upper-storey location and asbestos. Here's what each one actually adds to a standard 6 m² mid-range Sydney job, calculated by changing one variable at a time.
| Change | Effect on total (inc. GST) |
|---|---|
| Keep the existing layout (refresh instead of full strip) | −$2,720 |
| Drop from standard porcelain to budget ceramic tiles | −$1,670 |
| Tile walls to half height instead of full height | −$1,750 |
| Add a bath | +$2,780 |
| Upgrade to premium large-format or stone tiles | +$2,510 |
| Bathroom on an upper floor instead of ground | +$2,600 |
| Relocate walls or plumbing for a new layout | +$2,180 |
Things that push costs up
- Moving plumbing — shifting the toilet, shower or vanity means re-routing pipes through the slab or wall cavity, and re-cutting the set-down (the recessed floor section that lets the finished tile height sit flush with the rest of the house). Budget $2,000–$5,000. The plumbing quote calculator prices this trade on its own.
- Asbestos in older homes — pre-1990 Sydney homes, especially fibro in the Western Suburbs and Inner West, may have asbestos sheeting behind tiles or in the ceiling. Licensed removal is legally required and adds $1,500–$4,000. Check estimated removal costs with the asbestos removal cost calculator, and see Sydney-specific asbestos removal costs for the local picture. Safe Work Australia sets the national framework; SafeWork NSW enforces it.
- Structural issues — rotten floor joists, termite damage to framing or cracked concrete slabs all need fixing before the new bathroom goes in.
- Upper-storey bathrooms — working above ground floor means more complex waterproofing, harder material handling, and sometimes structural engineering for heavy items like a freestanding stone bath.
- Access difficulty — if your bathroom is at the back of a narrow terrace with no rear lane, getting materials in and waste out takes longer, and labour is time.
Things that keep costs down
- Keeping the existing layout — the single biggest lever available to you, worth roughly $2,700 on a standard job.
- Standard tile sizes — 300x600 wall tiles and 300x300 or 600x600 floor tiles are faster to lay than mosaics, hexagons or large-format slabs.
- Half-height wall tiling — tile to 1.2 m and paint above with a proper wet-area paint. It saves around $1,750 and looks deliberate if the tile line is set well.
- Supply your own fixtures — buying your vanity, toilet and tapware yourself from a Reece or Bunnings trade account (instead of through the builder) can save 15–25% on those items. Just make sure they land on site on time; a missing vanity stalls the whole fit-off.
- Off-peak timing — booking for autumn or winter (March–August) gets you better availability and occasionally lower labour rates.
Why do small bathrooms and ensuites cost more per square metre?
Because the fixed costs don't shrink. A waterproofer charges a minimum call-out whether your shower is 1 m² or 3 m², and the plumber, electrician and skip bin work the same way. Run identical mid-range scopes through the calculator at different sizes and the per-square-metre cost falls as the room grows.
| Bathroom floor area | Mid-range total (inc. GST) | Cost per m² |
|---|---|---|
| 3 m² (small ensuite) | ~$17,600 | ~$5,865 |
| 4 m² | ~$18,950 | ~$4,738 |
| 6 m² (standard) | ~$21,650 | ~$3,610 |
| 9 m² (large family) | ~$25,700 | ~$2,857 |
That's a 2x swing in rate per square metre for the same finish level. It's the clearest argument against budgeting a small bathroom by multiplying a "cost per m²" figure you found online.
Here's how the three bands play out across sizes:
| Bathroom size | Budget refresh | Mid-range reno | Luxury |
|---|---|---|---|
| Small ensuite (2–3 m²) | $8,000 – $14,000 | $18,000 – $28,000 | $30,000 – $45,000 |
| Standard (4–6 m²) | $10,000 – $18,000 | $22,000 – $38,000 | $40,000 – $55,000 |
| Large / master (7–10 m²) | $15,000 – $22,000 | $30,000 – $50,000 | $55,000 – $75,000+ |
For ensuites specifically, the savings come from keeping the layout exactly as it is and spending on surfaces, fixtures and lighting instead. A wall-hung vanity and a large mirror make a tiny ensuite feel twice the size. Our national guide to small bathroom renovation costs goes deeper on compact layouts.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
How long does a bathroom renovation take in Sydney?
Most mid-range Sydney bathroom renovations take 2–3 weeks on site, plus 2–6 weeks of planning and ordering beforehand. The on-site part is rarely what blows the schedule out.
| Phase | Duration |
|---|---|
| Planning, design and council checks (if needed) | 2 – 6 weeks |
| Material ordering and lead times | 1 – 4 weeks |
| Demolition and strip-out | 1 – 2 days |
| Plumbing and electrical rough-in | 2 – 3 days |
| Waterproofing (apply + cure time) | 2 – 3 days |
| Tiling (walls and floor) | 3 – 5 days |
| Fit-off (vanity, toilet, shower screen, accessories) | 2 – 3 days |
| Final clean and handover | 1 day |
Add a week if you're dealing with asbestos removal or significant plumbing changes. Popular tiles and vanities routinely carry 4–6 week lead times in Sydney, and that's the delay that catches most people off guard — not the trades.
The one phase you cannot compress is the waterproofing cure. Membranes need their full manufacturer-specified curing time before tiling; rushing it is the most common cause of failures that show up 18 months later as bubbling paint on the other side of the wall.
If you've got only one bathroom, talk to your builder about staging. Plenty of tradies can sequence the work so you keep a functioning toilet for most of the build.
What are the NSW rules on waterproofing, licensing and contracts?
In NSW, wet-area waterproofing must comply with AS 3740 and the National Construction Code, the work must be done by a licensed tradesperson, and any residential job over $5,000 needs a written contract. These aren't optional extras — they're what separates a renovation you can sell a house on from one you can't.
Waterproofing and certification. The membrane must be installed to AS 3740 and you should receive a certificate of compliance before tiling begins. Ask specifically about the fall to waste (the graded slope in the floor screed that drives water to the drain) and the puddle flange (the collar that seals the waste outlet into the membrane). Those two details are where most failed showers actually fail.
Licensing. Plumbing, electrical and waterproofing work in NSW must be carried out by appropriately licensed tradespeople. NSW Fair Trading maintains a public licence check — use it before you sign anything, and confirm the licence covers the specific category of work.
Contracts and insurance. For residential building work over $5,000 including GST, NSW requires a written contract. Above the $20,000 threshold, home building compensation (HBC) cover is required and the certificate must be provided before you pay a deposit — a full bathroom renovation often sits right on that line, so ask which side of it your job falls on.
Council approval. Most bathroom renovations in Sydney are exempt development because they don't change the building's footprint or structure. You'll need approval if you're adding a bathroom where none existed, altering external plumbing, or removing a load-bearing wall. Strata apartments are a separate matter entirely — most by-laws require owners corporation approval for any work affecting common property, and waterproofing membranes usually count.
How do you read a bathroom renovation quote?
A good quote is itemised by trade, not a single lump sum. If you can't see where the money goes, you can't compare two quotes — and you can't tell which one has quietly left out the waterproofing.
What a solid quote includes:
- Line-by-line breakdown of labour and materials for each trade (demolition, plumbing, waterproofing, electrical, tiling, carpentry)
- Allowances for fixtures — vanity, toilet, shower screen, tapware — with specific product names or a stated allowance amount
- Skip bin and waste removal costs
- A clear scope of work: what's included and, just as importantly, what's excluded
- Payment schedule — typically a deposit, progress payments, and a final payment on completion
- Timeline with estimated start and completion dates
- Builder's licence number, ABN and insurance details
Red flags to watch for:
- A quote that's one number with no breakdown — you've got no idea what you're paying for
- No mention of waterproofing or a waterproofing certificate — legally required in NSW
- An unusually low price propped up by vague "provisional sums" or "TBC" on major items — the final bill will be much higher
- A deposit demand above the NSW Fair Trading limit for residential building work — check the current threshold before you transfer anything
- No written contract on a job over $5,000 — that's not just risky, it's non-compliant
Always get at least three quotes. The cheapest one isn't the best value — compare scope, inclusions and track record. Browse the full range of construction and building calculators to price individual trades before you sit down with a builder.
Frequently asked questions
Q: How much does a basic bathroom renovation cost in Sydney?
A: A basic bathroom refresh in Sydney — new vanity, taps, mirror, paint and a shower reseal without changing the layout — typically costs $10,000 to $18,000 inc. GST in 2026. That assumes the existing waterproofing and tile layout stay intact. If the membrane needs replacing, add $1,200–$2,500. Run your own numbers through the bathroom renovation quote calculator for an itemised estimate.
Q: How long does a bathroom renovation take in Sydney?
A: Most mid-range Sydney bathroom renovations take 2–3 weeks of on-site work, plus 2–6 weeks beforehand for planning, design and material ordering. The biggest delays come from tile and vanity lead times — 4–6 weeks for popular ranges — and from waiting for waterproofing to cure properly. Rushing the cure is never worth it; a failed membrane means stripping the tiles and starting the wet-area work again.
Q: Do I need council approval for a bathroom renovation in Sydney?
A: Generally no. Most bathroom renovations in Sydney are exempt from council approval because they don't change the building's footprint or structure. You will need a complying development certificate or a development application if you're adding a new bathroom where one didn't exist, changing external plumbing, or doing structural work like removing a load-bearing wall. If you're in a strata apartment, check your by-laws first — owners corporation approval is usually required for work touching common property.
Q: What's the most expensive part of a bathroom renovation?
A: Tiling and plumbing, consistently. Together they account for 40–50% of a mid-range bathroom reno. Tiling labour in Sydney runs $60–$90 per square metre for standard tiles and more for large-format or mosaic patterns, and remember the tiled area is about five times the floor area when you tile walls to full height. Plumbing rough-in for a full reno sits between $2,500 and $5,000. The tiling quote calculator will price the tiling line on its own.
Q: Is waterproofing legally required for bathroom renovations in NSW?
A: Yes. Under the National Construction Code and AS 3740, all wet areas in NSW must be waterproofed before tiling, and the work must be done by a licensed tradesperson. You must receive a certificate of compliance — without it you can't get valid home building compensation cover, and you'll have problems at sale time. On a full renovation, waterproofing adds roughly $1,900 inc. GST once margin and GST are counted. Never skip it, even on a budget job.
Q: How much does an ensuite renovation cost in Sydney?
A: A small ensuite renovation of 2–3 m² costs $18,000 to $28,000 for a mid-range fitout in Sydney in 2026. The per-square-metre cost is higher than a standard bathroom — around $5,900 per m² at 3 m², against roughly $3,600 per m² at 6 m² — because waterproofing, plumbing, electrical and waste-removal minimums don't scale down. Keeping the existing layout is the single best way to control the cost of an ensuite reno.
Q: Does a bathroom renovation add value to a Sydney home?
A: A well-executed bathroom renovation is one of the more reliable value-adding jobs in a Sydney home, but the return depends on matching the finish to the suburb rather than spending as much as possible. A $50,000 luxury bathroom in a home where comparable sales sit at the mid-range end rarely returns its cost. The safest play is a clean, compliant, mid-range renovation with certified waterproofing and documentation you can hand to a buyer — the certificate matters more at sale time than the tapware brand does.
Q: Can I renovate a bathroom myself to save money?
A: Partly, but not the parts that cost the most. In NSW, plumbing, electrical and waterproofing must be done by licensed tradespeople, and those three trades plus tiling make up the bulk of the bill. Homeowners can realistically handle demolition, painting, and sourcing their own fixtures — that last one alone can save 15–25% on vanities, toilets and tapware. Doing unlicensed wet-area work voids insurance and creates a disclosure problem when you sell.
Q: How much deposit should I pay for a bathroom renovation in NSW?
A: Less than you might be asked for. NSW Fair Trading caps deposits on residential building work, and any builder demanding a large upfront payment before materials are ordered is a warning sign. Pay against a written contract with a defined payment schedule tied to progress milestones — deposit, rough-in complete, waterproofing certified, practical completion. Check the current deposit limit on the NSW Fair Trading site before you transfer anything, and never pay cash without a receipt and a contract.
Q: Should I project-manage the renovation myself or hire a builder?
A: Hiring a builder or bathroom renovation specialist costs 10–20% more but saves you coordinating 4–6 trades, managing deliveries and solving problems on the fly. If you've done it before and have reliable tradies on speed dial, self-managing saves real money. First-timers are almost always better off paying the margin — a two-day gap between the waterproofer and the tiler costs more in schedule blowout than the management fee did.
Q: How can I get an accurate bathroom renovation quote online?
A: Use a quote calculator that factors in your bathroom size, scope and finish level rather than a flat per-square-metre figure. The Leadkit calculator gives an itemised estimate in under a minute using the rates published on this page. It isn't a binding quote — your tradie confirms the final price after inspecting the job — but it gives you a defensible starting point for budgeting and for comparing builders. If you also need a plumber priced separately, our Sydney plumber callout cost guide covers hourly and callout rates.
Plan your budget, then get quotes
A bathroom renovation is one of the best investments you can make in a Sydney home — for daily comfort and for resale. It's also one of the easiest projects to blow the budget on.
Start by working out which price band you're realistically in. Be honest about finishes: the difference between a $25,000 reno and a $45,000 reno is almost always the tiles, tapware and shower screen, not the labour. Settle your layout before you talk to tradies, decide early whether the plumbing moves, and order materials well ahead to avoid dead time on site.
Then get at least three written quotes and compare them line by line. Check what's included, check allowances versus fixed prices on fixtures, and make sure waterproofing certification is explicitly listed. Every price on this page is a guide — this is a price indication only, and your tradie will confirm the final price after assessing the job.
