How Much Does Bathroom Renovation Cost in Sydney 2026
If you're staring at cracked tiles, a dodgy exhaust fan and a shower screen that's seen better days, you're probably wondering what it actually costs to renovate a bathroom in Sydney right now. The short answer: anywhere from $10,000 for a basic refresh to $55,000+ for a full luxury fitout — and the gap between those numbers comes down to size, finishes and how much structural work is involved.
The longer answer is what this guide is for. We'll break down three realistic price bands, walk through every line item you'll see on a quote, explain what pushes costs up (and what keeps them down), and give you a realistic timeline so you can plan around it.

Sydney bathroom renovation costs have shifted in 2026. Material prices have stabilised after the post-COVID spike, but labour remains tight — especially for licensed waterproofers and tilers in the Inner West and Eastern Suburbs. Knowing where your money goes puts you in a much stronger position when you're comparing quotes.
Three price bands: budget, mid-range and luxury
Not every bathroom reno is a full gut-and-start-again job. Here's how costs typically land across Sydney in 2026:
| 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 3m x 2m 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.
Important note: these are guide prices only. Your tradie will confirm the final price after assessing the job — every bathroom has its own surprises hiding behind the tiles.
Itemised cost breakdown — where your money actually goes
Here's a typical line-item breakdown for a mid-range Sydney bathroom renovation in 2026. This is the kind of detail 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 |
Tiling and plumbing are typically the two biggest costs. If you're choosing large-format porcelain tiles (600x600 or bigger), expect the tiling labour to sit at the higher end because they're harder to cut and lay. You can get a sense of tiling costs specifically with the tiling quote calculator.
Waterproofing is non-negotiable in NSW — it must comply with AS 3740, and you'll 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 waterproofing costs separately, check the waterproofing enquiry page.
What drives the cost up (and what keeps it down)
Understanding what moves the needle helps you make smarter trade-offs during the planning stage.
Things that push costs up
- Moving plumbing — shifting the toilet, shower or vanity to a new position means re-routing pipes through the slab or wall cavity. This alone can add $2,000–$5,000. Use the plumbing quote calculator to estimate plumbing-specific costs.
- 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 depending on the area. You can check estimated removal costs with the asbestos removal cost calculator.
- Structural issues — rotten floor joists, termite damage to framing or cracked concrete slabs all need fixing before the new bathroom goes in.
- Premium finishes — natural stone tiles, brass tapware, custom vanities and underfloor heating all look great but add up fast.
- Upper-storey bathrooms — working above ground floor means more complex waterproofing and sometimes structural engineering for heavy items like freestanding baths.
- 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.
Things that keep costs down
- Keeping the existing layout — if the toilet, shower and vanity stay where they are, you avoid the most expensive plumbing work.
- Standard tile sizes — 300x600 wall tiles and 300x300 or 600x600 floor tiles are faster to lay than mosaics, hexagons or large-format slabs.
- Supply your own fixtures — buying your vanity, toilet and tapware yourself (instead of through the builder) can save 15–25% on those items. Just make sure they're delivered on time.
- Off-peak timing — booking your reno for autumn or winter (March–August) can get you better availability and sometimes lower labour rates.
Realistic timeline for a Sydney bathroom renovation
One of the most common questions is "how long will I be without a bathroom?" Here's what a typical mid-range reno looks like:
| 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 |
Total on-site time: 2 – 3 weeks for a straightforward mid-range job. Add a week if you're dealing with asbestos removal or significant plumbing changes. The planning and ordering phase beforehand is what catches most people off guard — popular tiles and vanities can have 4–6 week lead times in Sydney.
If you've got only one bathroom, talk to your builder about temporary arrangements. Some tradies can stage the work so you have a functioning toilet for most of the build.
How to read a bathroom renovation quote
A good quote should be itemised, not just a single lump sum. Here's what to look for:
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 what's excluded
- Payment schedule — typically a deposit (10–20%), 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 just one number with no breakdown — you've got no idea what you're paying for
- No mention of waterproofing or waterproofing certificate — this is legally required in NSW
- Unusually low price with vague "provisional sums" or "TBC" on major items — the final bill will be much higher
- Requesting more than 20% deposit upfront — this is a warning sign under NSW Fair Trading guidelines
- No written contract — verbal agreements leave you unprotected if things go sideways
Always get at least three quotes for comparison. The cheapest quote isn't always the best value — look at scope, inclusions and the tradie's track record. Browse the full range of construction and building calculators to estimate individual trade costs before you sit down with a builder.
Small bathroom and ensuite renovation costs
Small bathrooms (under 5m²) and ensuites are the most common renovation type in Sydney, especially in apartments and older terraces. Here's the thing: small doesn't mean cheap.
| Bathroom size | Budget refresh | Mid-range reno | Luxury |
|---|---|---|---|
| Small ensuite (2–3m²) | $8,000 – $14,000 | $18,000 – $28,000 | $30,000 – $45,000 |
| Standard (4–6m²) | $10,000 – $18,000 | $22,000 – $38,000 | $40,000 – $55,000 |
| Large / master (7–10m²) | $15,000 – $22,000 | $30,000 – $50,000 | $55,000 – $75,000+ |
The per-square-metre cost is actually higher for smaller bathrooms because the fixed costs — waterproofing, plumbing rough-in, electrical, skip bin — don't shrink much. A waterproofer still charges a minimum call-out whether your shower is 1m² or 3m². Same goes for the plumber.
For ensuite renovations specifically, the biggest savings come from keeping the layout exactly as it is and focusing on fresh surfaces, new fixtures and good lighting. A well-chosen wall-hung vanity and large mirror can make even a tiny ensuite feel twice the size.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
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 between $10,000 and $18,000 inc. GST in 2026. This assumes you're keeping the existing waterproofing and tile layout intact. If the waterproofing membrane needs replacing, expect to add $1,200–$2,500. For a more detailed estimate, try the bathroom renovation quote calculator.
Q: How long does a bathroom renovation take in Sydney?
A: Most mid-range bathroom renovations in Sydney take 2–3 weeks of on-site work. Add 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 waiting for waterproofing to cure properly. Rushing the waterproofing curing time is never worth it.
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. However, if you're adding a new bathroom where one didn't exist before, changing external plumbing, or the work involves structural changes (removing a load-bearing wall), you'll need a complying development certificate or a development application through your local council.
Q: What's the most expensive part of a bathroom renovation?
A: Tiling and plumbing are consistently the two biggest costs, together accounting 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. Plumbing rough-in for a full reno (moving or replacing all pipework) sits between $2,500 and $5,000. Use the tiling quote calculator to get a tiling-specific estimate.
Q: Is waterproofing legally required for bathroom renovations in NSW?
A: Yes. Under the National Construction Code (NCC) and AS 3740, all wet areas in NSW must be waterproofed by a licensed waterproofer before tiling. You must receive a certificate of compliance — without it, you can't get a valid home building warranty, and you'll have issues if you sell the property. Never skip this step, even on a budget renovation.
Q: How much does an ensuite renovation cost in Sydney?
A: A small ensuite renovation (2–3m²) in Sydney costs between $18,000 and $28,000 for a mid-range fitout in 2026. The per-square-metre cost is higher than a standard bathroom because fixed costs like waterproofing, plumbing and electrical don't scale down much. Keeping the existing layout is the single best way to control costs on an ensuite reno.
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 different trades (demolition, plumber, waterproofer, electrician, tiler, painter), managing deliveries, and dealing with problems. If you've done it before and have reliable tradies, self-managing can save money. First-timers are almost always better off paying for a project manager — the stress and potential for costly mistakes isn't worth the saving.
Q: How can I get an accurate bathroom renovation quote online?
A: The fastest way is to use an online quote calculator that factors in your bathroom size, scope of work and finish level. The Leadkit bathroom renovation calculator gives you an itemised estimate in under a minute. It's not a binding quote — your tradie will confirm the final price after inspecting the job — but it gives you a solid starting point for budgeting and comparing quotes from different builders.
Plan your budget, then get quotes
A bathroom renovation is one of the best investments you can make in a Sydney home — both for daily comfort and resale value. But it's also one of the easiest projects to blow the budget on if you don't plan properly.
Start by figuring out which price band you're realistically in. Be honest about your 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. Get your layout sorted before you talk to tradies, know whether you're keeping the plumbing where it is, and order materials early to avoid delays.
Once you've got a rough budget in mind, get at least three written quotes and compare them line by line. Look at what's included, check for allowances versus fixed prices on fixtures, and make sure waterproofing certification is explicitly listed.
