If you’ve started pricing up a bathroom renovation and your head’s spinning from how wildly the quotes differ, you’re not going mad. One tradie says $15,000, the next says $40,000, and you’re left wondering if someone’s trying it on. They’re probably not they’re just quoting completely different jobs.
We’ve been renovating bathrooms across Australia for a long time now, and if there’s one question we get asked more than any other, it’s this: how much does a bathroom renovation cost? So let’s cut through the vague “it depends” answers and give you real numbers.
Quick Answer: What Does a Bathroom Renovation Cost in Australia?
The average bathroom renovation cost in Australia sits at around $26,000, according to the Housing Industry Association’s most recent Kitchens and Bathrooms data. But that’s just the middle of the road. In practice, most homeowners land somewhere between:
- Budget refresh: $10,000 – $20,000
- Mid-range renovation: $20,000 – $35,000
- Premium/luxury renovation: $35,000 – $55,000+
Where you fall in that range comes down to the size of your bathroom, the quality of fixtures and tiles you choose, whether you’re moving plumbing, and which city (or even suburb) you’re renovating in.
That’s the honest, no-nonsense answer. Now let’s get into the detail, because the devil really is in it.
What Actually Drives the Cost of a Bathroom Renovation?
Every bathroom renovation cost breaks down into the same handful of ingredients — it’s just the quantities that change depending on your job.
1. Size of the Bathroom
A standard Australian bathroom is somewhere between 4 and 7 square metres. Squeeze into a tiny powder room and you’ll naturally spend less. Stretch out into a big family bathroom or a hotel-style ensuite, and the tiling, waterproofing and fixtures all scale up with it.
2. Scope of Work
This is the big one. There’s a world of difference between:
Layout change moving the toilet, shower or vanity means shifting plumbing and drainage, which adds real cost (and often needs council or strata sign-off).
Cosmetic refresh, new tapware, a repaint, updated mirror and lighting, maybe a new vanity. Layout and plumbing stay put.
Full renovation everything’s ripped out to the studs. New waterproofing, tiling, plumbing, electrical, and fixtures throughout.
3. Materials and Fixtures
Tiles alone can range from $30 a square metre to well over $150 for imported stone-look porcelain. Tapware, showerheads and vanities follow the same pattern a budget mixer tap might be $80, while a designer brand can run into the thousands.
4. Waterproofing and Compliance
This one’s non-negotiable, and it should never be the place you try to cut corners. Every wet area renovation in Australia must comply with AS 3740, the Australian Standard for waterproofing. Licensed waterproofing, plumbing and electrical work all add to your bathroom renovation cost, but they’re what stop you from dealing with a mould-ridden, leaking disaster two years down the track and most insurers won’t touch a claim if the work wasn’t done to code.
5. Structural Surprises
Older Australian homes especially anything built before the 1990s can hide rotten timber, ageing pipework, or even asbestos sheeting behind the tiles. It’s genuinely common for these issues to only surface once demolition starts, which is why we always recommend building in a 10–20% contingency on top of your quoted price.
6. Location
Where you live genuinely moves the needle. Labour rates, council requirements and even freight costs for materials all vary by state and city.
Bathroom Renovation Cost by City
Because so many of you ask us about the average bathroom renovation cost in your specific city, here’s how the major markets generally compare:
| City | Typical Range |
|---|---|
| Sydney | $18,000 – $40,000 (Sydney runs 15–25% above the national average due to labour rates and stricter compliance) |
| Melbourne | $16,000 – $35,000 |
| Brisbane | $15,000 – $32,000 |
| Perth | $15,000 – $32,000 |
| Adelaide | $14,000 – $30,000 |
These are ballpark figures for a standard-sized bathroom with a mid-range fit-out. A bathroom renovation cost in Sydney, for example, will always run a bit hotter than the same job in Adelaide, simply because trade labour and inner-city access costs more.
Small Bathroom Renovation Cost
Good news if you’re working with a compact space a small bathroom renovation cost is genuinely lower, and it’s one of the best value-for-money jobs you can do in a house. Think powder rooms, ensuites, or older-style bathrooms under 4 square metres.
You’re typically looking at $10,000 to $18,000 for a small bathroom renovation, provided the layout stays the same and there are no structural surprises. An ensuite renovation tends to sit at the lower-to-middle end of that range too, since ensuites are usually more compact than main bathrooms.
Budget Bathroom Renovation: What Can You Actually Get for Less?
We get it not everyone’s chasing a marble-and-brass showstopper. A budget bathroom renovation is absolutely achievable without cutting corners on the things that matter (looking at you, waterproofing).
Here’s what tends to move the needle most on a tighter budget:
- Keep the existing layout. Every metre you move plumbing adds cost. Leaving the toilet, shower and vanity where they already are is the single biggest saving you can make.
- Mix your finishes. Splash out on a feature tile for the shower niche and go budget-friendly on the rest of the wall tiling. Nobody will know the difference.
- Choose a stock-standard vanity over a custom-built one off-the-shelf units have come a long way and can look genuinely high-end.
- Reglaze instead of replace, where the bathtub or tiles are structurally sound but just tired-looking.
- Get three quotes, not one. Pricing on trade labour varies more than people expect, and a proper comparison is the easiest money you’ll ever “make.”
None of this means going cheap on the bones of the job a cheap bathroom renovation that skips waterproofing or uses unlicensed trades will cost you a lot more in the long run when something fails.
Bathroom Renovation Cost Breakdown: Where the Money Goes
For a typical mid-range bathroom renovations, here’s roughly how the budget splits:
| Item | Approx. % of Budget |
|---|---|
| Labour (plumbing, electrical, tiling, carpentry) | 35–40% |
| Tiles and waterproofing | 15–20% |
| Fixtures and fittings (toilet, vanity, tapware, shower) | 20–25% |
| Demolition and waste removal | 5–8% |
| Design, permits and project management | 5–10% |
| Contingency | 10–20% |
Labour is consistently the biggest slice of any bathroom renovation cost, which is exactly why the size of your space and the complexity of the job (layout changes especially) push the price around more than the tiles you pick.
How to Get an Accurate Bathroom Renovation Quote
The number one thing that trips people up isn’t the price of tiles or tapware it’s an inaccurate quote at the start. Before you commit to anyone, make sure your quote clearly spells out:
- Whether it’s a fixed-price quote or an estimate that can move
- What’s included in waterproofing and whether it’s certified to AS 3740
- Who’s supplying fixtures you or the builder and what allowance is set aside for them
- Whether demolition, disposal and any asbestos testing are included
- What happens if structural issues are found once walls come down
A properly detailed quote should feel like it’s answering questions before you’ve even asked them. If a quote is suspiciously low and vague on detail, that’s usually where the “surprise” costs come from later.

The average bathroom renovation cost in Australia is around $26,000, with most projects falling between $15,000 and $35,000 depending on size, materials and location.
What is the cheapest way to renovate a bathroom?
Keep the existing layout, avoid moving plumbing, choose a stock-standard vanity, and mix budget tiles with one feature tile. A budget bathroom renovation can realistically come in under $15,000 for a small space.
Is $10,000 enough for a bathroom renovation?
It can be, but only for a cosmetic refresh new tapware, paint, lighting, a new vanity where the layout, tiles and waterproofing don’t need touching. A full renovation for $10,000 is very rare in most Australian cities.
How much does an ensuite renovation cost?
An ensuite renovation typically costs a little less than a main bathroom, usually landing between $10,000 and $20,000, simply because ensuites tend to be smaller.
Why do bathroom renovation quotes vary so much?
Because “bathroom renovation” can mean anything from a $10,000 cosmetic refresh to a $50,000 full rebuild with a layout change. Always compare quotes for the same scope of work, not just the bottom-line number.
How much does a small bathroom renovation cost?
A small bathroom renovation cost typically runs between $10,000 and $18,000, assuming the layout stays put and there’s no structural work needed. Powder rooms and older, compact bathrooms fall into this bracket most often.
How much does a new bathroom cost if I’m adding one?
Adding a brand-new bathroom where one didn’t exist before say, converting a walk-in robe into an ensuite usually costs more than renovating an existing one, typically $20,000 to $40,000+, because you’re running entirely new plumbing, drainage and often electrical circuits from scratch.
How long does a bathroom renovation take?
Most full bathroom renovations take 3 to 6 weeks from demolition to final fit-off, though this stretches out if structural issues turn up, materials are on back-order, or the job involves moving plumbing. A cosmetic refresh can sometimes be done in under two weeks.
Do I need council approval for a bathroom renovation?
Usually not for a like-for-like renovation. But if you’re changing the layout, altering drainage points, or the work affects structural walls, you may need council or strata approval depending on your state and whether you’re in an apartment. It’s worth checking before you commit to a design.
Can I renovate my bathroom myself to save money?
You can handle cosmetic jobs yourself painting, changing a mirror, swapping a showerhead. But plumbing, electrical and waterproofing legally have to be done by licensed tradespeople in every Australian state. Skipping this to save money isn’t just risky, it can void your home insurance and make the property difficult to sell down the track.
Does a bathroom renovation add value to my home?
Generally, yes. A well-executed bathroom renovation is consistently one of the better returns on investment in Australian real estate, particularly for homes with only one bathroom or a dated original one. That said, it’s rarely dollar-for-dollar the value is more about making the home sellable and appealing than directly recouping the full renovation cost.
Is it cheaper to renovate a bathroom or move the layout?
Keeping your existing layout is almost always cheaper. Moving the toilet, shower or vanity means relocating plumbing and drainage, which can add several thousand dollars to your bathroom renovation cost before you’ve even chosen a tile.
