A mid-range bathroom renovation in Australia in 2026 typically costs from about $20,000 to $35,000, with budget refreshes often starting from a lower amount and premium jobs exceeding that range. Scope is what moves you between those bands, particularly layout changes and waterproofing standards. Whatever tier you’re aiming for, get at least three quotes from licensed local tradies and build in a 10 to 20% contingency before you sign anything.
TL;DR:
- A mid-range bathroom renovation in Australia in 2026 typically costs between $20,000 and $35,000, depending on scope and layout changes.
- Waterproofing, tiling, and labour generally account for more than half of the total renovation cost, with many quotes excluding fixtures and fittings.
- Moving fixtures or changing layouts, especially involving slab cutting, can significantly increase costs by several thousand dollars, pushing projects into the premium tier.
- Location impacts costs, with Sydney being about 27 to 28% more expensive than Hobart due to higher labour rates and logistical challenges.
- Always allow a 10 to 20% contingency for unexpected issues such as hidden damage or scope changes, especially in older homes.

What does a bathroom renovation cost in Australia in 2026?
Most Australian bathroom projects fall into three clear tiers, and knowing which one you’re in stops you comparing quotes that were never meant to be compared.
A budget renovation typically involves keeping the existing footprint and plumbing locations untouched, and tends to be at the lower end of renovation costs. You’re swapping out the toilet, vanity, tapware and tiles, maybe repainting, without moving a single pipe. Labour involvement is comparatively light because there’s no demolition of walls or reconfiguration of drainage.
A mid-range renovation usually involves a full strip-out, new waterproofing membrane, better-quality tiles and fixtures, and often some minor layout tweaks such as swapping a bath for a bigger shower. HIA and industry data put the national average bathroom renovation around $26,000, which lands within this bracket.
A premium renovation brings in freestanding baths, heated flooring, custom joinery, frameless glass, and often a layout overhaul with plumbing relocated to a different wall or corner.
Per-square-metre figures get thrown around a lot in this space, but treat them with caution. A tiny ensuite can cost close to $2,000 per square metre once you account for fixed trade call-out fees, while a large family bathroom might land closer to $1,000 per square metre because those same fixed costs are spread across more floor area.
That fixed-cost effect explains a pattern a lot of homeowners find counterintuitive:
- Small ensuites often cost nearly as much as much larger bathrooms, because waterproofing, plumber call-outs and trade sequencing create a price floor regardless of size.
- A 3 square metre ensuite can cost nearly as much as a 6 square metre standard bathroom.
- Doubling the floor area rarely doubles the bill, since tiling and fixtures scale with size but labour setup costs largely don’t.
Where does the money actually go? A bathroom renovation cost breakdown
Once you know your tier, the next useful step is breaking the number down by trade, because that’s the only way to sanity check a quote line by line.
- Demolition and waste removal — around 5 to 8% of the budget. Stripping tiles, old fixtures and sometimes a wall.
- Waterproofing — around 8 to 12%. Membrane application to floors and walls in wet areas, non-negotiable under Australian building rules.
- Tiling (materials and labour) — around 20 to 25%, one of the two biggest line items in most quotes.
- Plumbing — around 12 to 18%, higher again if pipes are being relocated.
- Electrical — around 5 to 8%, covering exhaust fans, lighting and heated towel rail wiring.
- Fixtures and fittings (vanity, toilet, tapware, shower screen, bath) — around 15 to 25%, and highly variable depending on brand and finish.
- Labour and project management — often folded across the above but commonly cited separately at 30 to 40% of total spend when tallied across all trades.
Tiling, waterproofing and labour together typically account for more than half the total budget in a standard Australian bathroom renovation, according to trade supplier cost guidance and national aggregator breakdowns.
Here’s the part that trips people up: many trade quotes are labour-only. Tilers, plumbers and electricians will often price their time and fixing materials, but expect you to separately purchase and supply tiles, tapware, the vanity and the bath. If a quote looks unusually cheap next to others you’ve collected, check whether it’s excluding fixtures you assumed were included. That single misunderstanding is behind more budget blowouts than any trade markup.
How much do different bathroom sizes actually cost?
Numbers land better against real rooms, so here’s how the tiers play out across three common Australian bathroom sizes.
- Small ensuite (around 3 to 4 square metres): A mid-range fit-out includes new waterproofing, a compact vanity, semi-frameless shower screen and standard tiling. Timelines typically range from a few weeks.
- Standard family bathroom (around 6 to 8 square metres): A mid-range job often includes a bathtub, full-height tiling and a double-basin vanity, with timelines of several weeks.
- Large family or main bathroom (10 square metres or more): Mid-range budgets cover layouts with separate baths and showers, double vanities, and higher-grade tiling; timelines are longer, especially if the layout changes.
Adding a bathtub where there wasn’t one, or relocating it to a different wall, can add several thousand dollars in plumbing costs depending on drainage and slab work. Moving a toilet or shower more than a metre or two from its existing waste point is one of the quickest ways to turn a mid-range budget into a premium one, because it usually means breaking into the slab.
Does location change your renovation budget?
Where you live in Australia genuinely moves the number, sometimes by more than people expect. Hipages data puts Sydney renovation costs around 27 to 28% higher than Hobart for a comparable scope of work, driven largely by labour rates and trade demand rather than material prices alone.
Brisbane and Melbourne generally sit somewhere between those two extremes, though local demand cycles matter more than the city name on the map. A booming renovation market in a particular suburb, or a shortage of licensed waterproofers in a regional pocket, can shift a quote noticeably even within the same state.
Supply logistics play a part too. Freight costs for tiles, tapware and custom joinery climb the further a project sits from a major distribution hub, which is part of why regional and remote renovations often carry a premium over metro equivalents even when local labour rates are lower.
The practical takeaway: treat national ranges as a starting point, then read at least two or three local quotes before locking in a budget. When you brief a tradie, mention your suburb and ask directly whether local labour availability or supply timeframes are likely to push the job above the ballpark figure you’ve seen online.
What causes bathroom renovation budgets to blow out?
Three things push a budget from mid-range into premium territory more often than anything else.
Layout changes top the list. Moving a toilet, shower or bath to a new position means relocating waste and water lines, which usually means cutting into the concrete slab. That single decision can add several thousand dollars and a week or more to the timeline, and it’s the point at which a straightforward renovation starts resembling a partial rebuild in terms of trade sequencing and cost.
Hidden damage is the second big risk, particularly in homes built before the 1990s. Once the old tiles and waterproofing membrane come off, it’s common to find rotted timber framing, corroded pipes, or evidence that a previous renovation was never properly waterproofed at all. This is exactly why a 10 to 15% contingency isn’t optional padding, it’s the realistic cost of not being able to see behind the wall until demolition is done.
Premium add-ons are the third, and they’re the ones you choose rather than discover:
- Underfloor heating: typically $800 to $1,500 extra
- Heated towel rails: around $300 to $600 installed
- Freestanding baths: often $1,500 to $3,000+ above a standard built-in bath, once plumbing changes are factored in
Pro Tip: Ask your tradie to price layout changes as a separate line item on the quote. That way you can see exactly what you’d save by keeping the toilet, shower and vanity where they already are, and decide if the new layout is worth it.
Which trades need licences for a bathroom renovation?
Plumbing, electrical work and waterproofing in Australian bathrooms must be carried out by licensed tradespeople, and waterproofing specifically needs to meet AS 3740, the national standard referenced in the National Construction Code for wet areas.
This adds cost, but it’s the cost that protects the rest of your investment. A poorly waterproofed bathroom risks water damage to framing and adjoining rooms, a problem that can cost far more to remediate than it would have to do properly the first time. Depending on your council, layout changes may also trigger notification requirements or the need for a certificate of compliance from your plumber, which adds a modest fee but gives you the paperwork you’ll want if you ever sell.
How do you get accurate bathroom renovation quotes?
Before you call a single tradie, put together a simple scope pack: rough measurements of the room, photos of the current layout, and a one-page list of what you want changed versus kept. Handing this to every tradie you approach means you’re comparing quotes on the same job, not three different interpretations of a vague conversation.
When quotes come in, ask each tradie the same set of questions:
- Are you licensed for plumbing, electrical and waterproofing work, or will you be subcontracting those parts?
- Does this quote include materials (tiles, tapware, vanity), or is it labour only?
- Who supplies items I need to choose myself, and what’s the lead time on ordering them?
- What warranty applies to the workmanship, and separately, what warranty applies to the waterproofing?
- How are variations handled if something unexpected turns up once demolition starts?
Collect three quotes minimum. It’s enough to spot an outlier without dragging the process out for weeks, and it gives you real leverage to query anything that looks off. Once you’ve settled on a tradie and a final figure, add a contingency of 10 to 20% on top, held back rather than spent, for the hidden damage and small variations that show up in almost every older bathroom once the tiles come off.
Pro Tip: Ask for the waterproofing warranty in writing before work starts, not after. Verbal assurances about compliance mean nothing if a leak shows up two years down the track.
How should renovation spend align with your property strategy?
If you’re renovating to sell or to grow equity for your next purchase, the finish level should match what buyers in that suburb actually expect, not what looks impressive online. High-end tapware and freestanding baths add real value in a suburb where buyers already expect that standard, but in a mid-market family pocket they often just eat into your margin without lifting the sale price to match. If you’re weighing renovation spend against buying in a growth suburb instead, our Banyo suburb profile shows how local market data shapes that decision.
A few honest observations from the renovation trail
Most budget blowouts I’ve seen trace back to two mistakes: accepting a quote without confirming what’s excluded, and skipping proper waterproofing to save a few thousand dollars upfront. Both feel harmless at the time. Neither is. If you want a second set of eyes on how a renovation fits your broader property plan, that’s where a managed approach earns its keep.

FAQ
Can you renovate a bathroom for $10,000 in Australia?
Yes, but only at the budget end, keeping the existing layout and plumbing untouched while updating tiles, tapware, the toilet and vanity. Any layout change or new waterproofing membrane typically moves the job into the mid-range bracket, starting from about $20,000.
What is the most expensive part of a bathroom renovation?
Labour and tiling together usually make up the largest share of the budget, often more than half of total spend once waterproofing is included. Plumbing costs climb sharply if fixtures are relocated rather than replaced in place.
What does a $10,000 bathroom remodel look like in Australia?
A budget refresh typically covers a cosmetic update: new toilet, vanity, tapware, shower screen and tiling within the existing footprint. It rarely stretches to moving plumbing, replacing the waterproofing membrane, or premium fixtures.
Can I renovate my bathroom for $5,000 in Australia?
It’s tight but possible for a very minor cosmetic update, such as repainting, replacing tapware, and swapping the vanity, without any tiling or plumbing work. A genuine renovation involving new tiles, waterproofing or fixtures generally requires a budget starting from the mid-range level, around $20,000 and up.
How much contingency should I budget for a bathroom renovation?
Set aside 10 to 20% of your total budget as contingency, held back rather than spent upfront. Older homes with unknown hidden damage behind existing tiles sit toward the higher end of that range.
