Bathroom Renovation Costs in Australia: What You’ll Actually Pay and Why
Bathroom renovation costs in Australia range from around $8,000 for a cosmetic refresh to $50,000 or more for a full premium renovation. That span isn’t imprecision — it reflects how differently two renovations in the same suburb can be specified, scoped, and executed.
The number in a quote is the output. What determines it is bathroom size, the scope of work, the material tier you’ve chosen, which trades are involved, where in Australia the job is, and how accessible the site is. A quote that looks low is often a quote that’s left several of those variables unaddressed.
Here’s what to know before you call anyone.
What a Bathroom Renovation Actually Costs in Australia
The problem with a single number is that it says nothing about what you’re getting. A $15,000 renovation and a $15,000 renovation are not the same job if one includes full waterproofing compliance and the other doesn’t.
$8,000–$15,000. New tiles over intact existing substrate, updated tapware, new accessories, mirror, vanity update. No structural work and no waterproofing strip-out. The right scope when existing substrate and waterproofing are confirmed sound — not when they’re assumed to be.
$18,000–$30,000. Full strip-out and re-tile, new fixtures and fittings, compliant waterproofing membrane to AS 3740, standard porcelain specification, coordinated trades. The most common scope for a full renovation in an existing Australian home.
$30,000–$50,000. Premium fixtures, imported or custom tile, feature wall treatment, heated floor, frameless shower screen, full trade coordination across multiple specialists. Both material and labour costs elevated above mid-range.
$50,000+. Feature stone, bespoke cabinetry, custom layout reconfiguration, architect or designer involvement. No standard cost ceiling once custom work is in scope. Budget for surprises — both in the build and in the site investigation.
$12,000–$20,000. Functional, durable, fast turnaround. Mid-range porcelain tile, reliable standard-spec fixtures, workmanlike tapware. Designed for rental yield or resale preparation — durability and low maintenance over aesthetics.
Which tier your renovation sits in determines the quote you should expect. A quote significantly below the floor of a given tier is either scoped differently or leaving items out. Both are worth understanding before you sign.
What Drives the Cost Gap
Six things determine where your renovation lands on the cost scale.
Every square metre is a multiplier. Labour and materials both scale with floor and wall area. A 4 m² ensuite and an 8 m² main bathroom at the same specification will have meaningfully different quotes — even if the tile choice is identical.
The single biggest variable. A cosmetic refresh over intact substrate costs a fraction of a full strip-out, re-waterproof, and re-tile. Defining scope before requesting quotes is the only way to get comparable numbers. Without it, you’re comparing different jobs.
Entry-level porcelain tiles cost $20–$50 per m². Premium imported stone runs $150–$350+ per m². That’s the same floor area at up to six times the material cost before any labour is added. The material tier decision is made at the showroom, not on site.
How many trades are required and how long each is on site. A full renovation with a waterproofer, tiler, plumber, and electrician working sequentially across two to three weeks costs more in labour than a single-trade job. Trade coordination is also a cost, whether it’s billed separately or absorbed.
Labour rates in Sydney and Melbourne sit at the upper end of the national range. Regional areas can offer lower rates but sometimes lower availability too. The state you’re renovating in materially affects the labour component of your quote, even when the spec is identical.
Second-storey bathrooms, strata buildings with goods lift restrictions, narrow corridors, and tight street parking all add time and cost. These factors are visible to a tiler before the quote is submitted. If they’re not reflected in it, ask why.
Quotes that don’t itemise these factors separately don’t make comparison possible — they just make the number smaller.
The Labour Side of the Quote
Labour is the cost variable most quotes obscure.
Supply costs are visible. You can compare tile prices across three suppliers in twenty minutes. Labour doesn’t work that way — it varies with the trade, the scope, the site conditions, and how complete the quote actually is. These are the trades typically involved in a full bathroom renovation, what they do, and what their costs look like.
A quote that bundles all labour into a single line doesn’t tell you what’s been included or what’s been left out. Ask for trade-by-trade itemisation before comparing quotes from different renovators.

Materials: What You’re Actually Paying For
Material costs are the part of a renovation budget most people can research. Tile prices, tapware, vanities — the supply side is visible and comparable across suppliers.
What’s less visible are the substrate and waterproofing materials — the fibre cement sheeting, waterproofing membrane, adhesive, and grout that sit between your tiles and the building structure. They’re present in every compliant renovation and they’re frequently absent from low quotes.
The waterproofing and substrate rows appear in every compliant renovation. They don’t disappear if they’re absent from a quote — they reappear later as variations, or they’re skipped and become a problem that surfaces years after the work is done.

Cost by State: Why Where You Are Matters
Two renovations with identical scope and specification can land at different final costs depending on where in Australia they’re located. The variable isn’t material cost — it’s labour.
The highest-demand market on the east coast. Labour rates sit at the upper end of the national range, particularly in Sydney metro where access and logistics add time to most jobs. The primary service area for the Lifestyle Bathrooms network.
Strong renovation demand. Melbourne metro rates are broadly comparable to Sydney. Regional Victoria generally lower, with trade availability varying by area. Lead times in inner-city Melbourne can extend timelines.
Brisbane and south-east Queensland sit mid-range nationally. Regional Queensland can offer lower rates where demand is lower, though trade availability is less predictable for specialist waterproofing and tiling work.
Adelaide generally has lower labour rates than the east coast capitals. A mid-range renovation in Adelaide will typically cost less in labour than the same scope and specification in Sydney or Melbourne.
Perth labour costs are elevated by competition from the mining sector for skilled trades. The WA market can run close to east coast capital rates, which tends to surprise investors managing properties across state lines.
These are directional differences, not precise percentages. A local renovator quoting on a local job will reflect current market conditions better than any published guide. What the guide tells you is that location belongs in the conversation when you’re budgeting — particularly for investors managing properties in more than one state.

What’s Usually Not in the Quote
These are the costs that turn an $18,000 quote into a $26,000 job.
The renovation budget conversation almost always focuses on tiles and tapware. The unplanned costs come from what’s behind the wall. By the time they’re visible, they’re not optional.
Waterproofing Failure Remediation
When old tiles come off and the waterproofing membrane underneath is cracked, bridging, or absent, the job changes. The membrane has to be replaced before anything else goes back on. Depending on the extent of the failure and whether the substrate has been compromised by water ingress, this can add $2,000–$6,000 to a job that was quoted without a prior site investigation.
The tiler couldn’t quote for it because they didn’t know it was there.
Substrate That Has to Be Replaced
Plasterboard behind tiles in a shower enclosure is not a compliant substrate in a wet area. It can’t be tiled over and it shouldn’t have been there in the first place. When a strip-out reveals plasterboard where fibre cement sheet is required, it has to be replaced before waterproofing and tiling can proceed. Budget $1,500–$4,000 depending on the extent, and expect a variation if this wasn’t flagged in the original quote because the scope was priced without a site visit.
Asbestos
Homes built before 1990 — and some built into the mid-1990s — may contain asbestos-containing materials in wet area linings, floor coverings, and tile adhesives. If asbestos is found during strip-out, work stops.
A licensed asbestos removalist is required by law. Testing and removal can add $1,500–$8,000 or more depending on the extent and type of material involved. This is not a cost that can be estimated from a desktop quote. Sometimes it’s only discovered mid-job, after demolition has started.
If the property was built before 1990, raise the question before work starts. An experienced renovator will know to check.
Drainage Relocation
Moving a floor waste or shower outlet position means cutting concrete, extending drainage lines, and reinstating the slab. It’s not a standard line item and it’s not a quick task — a plumber and concreter may both need to be on site on the same day. If your renovation involves any repositioning of wet area fixtures, confirm drainage relocation is in scope and explicitly costed before work starts. Finding it’s missing halfway through the job is a poor negotiating position.
Council or Strata Approvals
Not every bathroom renovation requires a DA or strata approval, but some do — particularly if you’re moving walls, relocating drainage, or working in a strata building with specific by-laws about wet area works. The tradie’s cost doesn’t change if approvals are required. The project timeline does — sometimes by months. That has its own carrying cost for investors and its own disruption cost for owner-occupiers.
Important: A quote that doesn’t include a site investigation — or that doesn’t clarify exclusions for existing substrate and waterproofing condition — is quoting what’s visible. What’s behind the wall is a separate conversation. One worth having before you accept the number.
Nine Things a Complete Bathroom Renovation Quote Should Include
A quote is a document. What it doesn’t say is as important as what it does.
These are the items most commonly absent from bathroom renovation quotes — and the ones most likely to produce a variation or a dispute when they’re missing.
Scope of demolition itemised separately
What is being removed, how it is being disposed of, and who is responsible. Demolition is a cost. It should not be assumed or bundled.
Substrate type and preparation method specified
Sheeting type, any levelling compound required, and preparation method for the tile format being used. “Substrate prep included” is not a specification.
Waterproofing standard and membrane type named
Which product, applied to which standard. AS 3740 compliance is not optional in a wet area. “Waterproofing included” without a named standard is not a commitment.
All trade inclusions listed separately
Waterproofer, tiler, plumber, electrician — each listed. If one is missing, confirm whether it is out of scope or simply not mentioned. The difference matters.
Tile format and adhesive type specified
Large-format tiles require flexible adhesive and back-buttering. If the quote does not name the adhesive type, it has not committed to the right one for the format being installed.
Movement joint locations noted
Silicone sealant at all internal corners and changes of plane. If the quote specifies grout at internal corners, request a correction before work starts, not after.
Fixtures and tapware specified or marked “by owner”
Ambiguity about who is supplying fixtures is how post-quote conversations become expensive. Brand and model, or a clear “owner supply” notation on every line.
Payment schedule tied to milestones
Progress payments at defined completion points — rough-in done, waterproofing done, tiling done — rather than arbitrary weekly payments with no link to progress on site.
Exclusions clause for existing conditions
What happens if strip-out reveals a failed membrane or non-compliant substrate? How will it be quoted and approved? No exclusions clause means no agreed process for the most common variation scenario.
Three or more items missing from a quote doesn’t necessarily mean the renovator is inexperienced. It might mean the quote is early-stage, or it might mean it’s been structured to look competitive. Either way, it’s not a basis for comparison with a quote that includes them.

Common Questions
The honest range is $8,000 to $50,000 or more, depending on the scope and specification. A cosmetic refresh — new tiles over intact existing substrate, updated tapware, new accessories — can be done at the lower end of that range. A full strip-out renovation with new waterproofing, premium fixtures, and custom tile work sits at the upper end.
What determines where your renovation lands in that range is scope (are you replacing just the visible surfaces, or everything including substrate and waterproofing?), material tier (entry porcelain vs premium imported stone is a 4–8× cost difference per square metre), the number of trades involved, and the labour market in your state. A mid-range full renovation in Sydney — full strip-out, AS 3740-compliant waterproofing, standard porcelain specification, coordinated trades — will typically cost between $18,000 and $30,000.
Labour and trades. Most people assume tiles. Tiles are visible and the per-metre price is easy to compare — but for a standard bathroom, total tile supply cost is often $1,500–$5,000. Labour across a waterproofer, tiler, plumber, and electrician on a full renovation runs $8,000–$18,000 or more, before materials.
The other item that surprises people is substrate and waterproofing. Not because it’s luxurious, but because it’s mandatory in a wet area and it adds $3,000–$8,000 to the job before a single tile goes on the wall. It’s also the item most commonly absent from low quotes.
Yes — with some qualifications.
A bathroom renovation generally adds more value than it costs to complete, particularly in the $15,000–$35,000 scope range applied to a property in the mid-to-upper tier of its local market. A dated, poorly maintained bathroom is a discount factor at auction. A clean, well-specified renovation removes that discount and can add a margin above it.
Where it gets complicated is overcapitalisation. A $60,000 luxury renovation on a property worth $600,000 in a suburb where comparable unrenovated properties are selling for $640,000 will not return its full cost at sale. The renovation scope has to be calibrated to the property and the market, not just to personal preference.
For rental properties, the calculation is different. The question is yield impact, not capital gain. A functional, durable, well-specified bathroom renovation in a rental typically pays back in reduced maintenance cost and improved tenant retention over a 5–7 year horizon, not in a single sale price uplift.
Two to three weeks on-site for a full renovation with a coordinated trade team working through sequenced stages — waterproofing, tiling, plumbing fit-off, electrical. Longer if trades aren’t coordinated, if approvals are required, or if the strip-out reveals substrate or waterproofing conditions that need to be resolved before work can continue.
Add two to four weeks before that for the planning and quoting phase, and two to four weeks for lead time on tiles and fixtures if you’re ordering anything that isn’t stocked locally.
For a cosmetic refresh in a small bathroom with an intact and sound existing substrate — yes. New tiles over a solid existing surface, updated tapware, new accessories, fresh grout and silicone. That scope can be achieved under $10,000 in most markets with the right specification.
For a full renovation — full strip-out, new AS 3740-compliant waterproofing membrane, new fibre cement substrate, new fixtures, new tiling with coordinated trades — no. A compliant full renovation in the current Australian market will not land under $10,000. Anyone quoting that figure for a full-scope job is either working with a very different definition of “full” or leaving significant items out of the price. It’s worth clarifying which, before accepting it.
