How Much Does It Cost to Refurbish a Bathroom in Australia?
A bathroom refurbishment and a full renovation are not the same thing, and treating them as interchangeable is one of the more reliable ways to end up with a quote that doesn’t match the job. This guide covers what a refurbishment actually includes, what it costs across Australian markets, when a partial scope makes sense, and when the condition of the existing bathroom means it doesn’t.
The figures in this guide are directional industry estimates, not quotes. What a refurbishment costs on a specific bathroom depends on its current condition, the trades the scope touches, and the local market. Use these numbers as a framework for understanding costs and interrogating quotes — not as a figure to put in front of a contractor.
Bathroom Refurbishment vs. Renovation — Where the Line Sits
A refurbishment works with the bathroom you have. Fixtures come out. New ones go in. Finishes get updated. The plumbing points stay where they are, the floor plan doesn’t change, and the waterproofing membrane underneath the tiles isn’t touched. That’s the scope — and it’s a narrower one than most people assume when they call something a “bathroom refresh.”
The test is straightforward: if tiles need to come up, if the waterproofing system needs to be opened, if a drain is being relocated, or if a wall is coming down, the job has crossed from refurbishment into renovation. Those categories require different trades, different licensing, and a different type of quote.
The reason this matters practically is that the scope drives the quote structure. A homeowner who describes a job as a cosmetic refresh when the brief actually requires waterproofing work and layout changes will receive a quote calibrated to the wrong scope. By the time that gap becomes clear, contracts are often signed and work has started. Getting the scope category right at the beginning — before the first trade is called — is how you avoid that.

What a Bathroom Refurbishment Typically Includes — and Doesn’t
A refurbishment operates at the surface layer. Everything it touches is visible — fixtures, fittings, finishes. Nothing it touches requires opening the wall cavity, lifting the membrane, or moving a drain. That boundary is what keeps a refurbishment a refurbishment. Cross it, and the scope changes category, even if the person quoting the job doesn’t flag it immediately.
- Vanity unit replacement — freestanding or wall-hung, same plumbing points
- Tapware replacement — basin mixer, bath spout, shower rose (same connection points)
- Toilet suite replacement — close-coupled, same waste point
- Mirror or shaving cabinet swap
- Bathroom accessories — towel rails, toilet roll holder, robe hooks
- Lighting fixture replacement — same circuit, same position
- Re-grouting existing tiles
- Tile resurfacing or tile-over where substrate is assessed as sound
- Partial floor re-tile where existing tiles are removed and substrate confirmed intact
- Shower screen replacement — same frame position
- Bath panel replacement or bath resurfacing
- Any work requiring tile removal to inspect or replace waterproofing
- Moving plumbing waste points or rough-in locations
- Structural wall changes or layout alterations
- New waterproofing membrane installation under AS 3740
- Drainage relocation or upgrade
- Subfloor repair or replacement
- New shower base requiring structural modification
- Ensuite additions
- Full gut-and-rebuild
What Bathroom Refurbishments Cost in Australia
The ranges below reflect typical scope and labour conditions across Australian markets. They are industry estimates — not quotes, and not a floor price. The condition of your existing bathroom, which trades the job touches, material choices, and local availability all push the actual cost up or down. Two bathrooms with an identical brief can land at opposite ends of the same range, or outside it entirely, depending on what’s found once the work starts.
One thing worth knowing about regional and outer-metro markets in NSW and elsewhere: licensed plumbers and electricians — both required for even basic tapware and lighting work — sometimes carry a small availability premium over metro rates. A quote that appears cheaper but doesn’t include those trade lines isn’t a better deal. It’s either an incomplete scope or unlicensed work priced in. The question to ask isn’t “what’s the total?” — it’s “what does this total include?”
Three things move refurbishment costs more than anything else. First, what’s found when the scope starts — a vanity removal that uncovers a plumbing configuration that needs correction, or tile removal that exposes a substrate in worse condition than it looked, changes the job. Second, access — in older homes with enclosed plumbing runs or confined spaces behind fixtures, even straightforward tapware swaps take longer. Third, the fixture and fitting spec itself, which has a wide price range at every tier.

When a Refurbishment Isn’t the Right Scope
A refurbishment is the right call when the bathroom underneath the fixtures is structurally sound — when the waterproofing is intact, the substrate is solid, and the brief is genuinely cosmetic. When those conditions don’t hold, a cosmetic scope is the wrong tool for the job. Proceeding with a fixture replacement on a failing waterproofing membrane doesn’t fix the problem; it puts new fittings on top of it. The five indicators below are the ones that most reliably signal a bathroom needs more than a refresh.
Grout failure or mould that keeps coming back
Grout that fails persistently isn’t a grouting problem — it’s a waterproofing question. Water getting through grout joints consistently suggests the membrane behind or below it may already be compromised. Re-grouting in this situation is a cosmetic fix that doesn’t address what’s causing the failure.
Damp, discolouration, or soft spots in adjoining rooms
Water appearing in an adjoining wall, ceiling cavity, or room below means water is already moving past the waterproofing system. That needs a licensed waterproofer and a rectification scope — not a new vanity.
Tiles that sound hollow or are starting to lift
A hollow sound when you tap a tile indicates the tile has separated from the substrate beneath it. Tiles that are visibly lifting suggest moisture movement. Both need investigation before any tiling work proceeds — tile-over or re-tile.
The bathroom has already been retiled over the original
Tile-on-tile installations are common in 1970s–80s Australian housing stock. If a bathroom has already had one round of tile-over, the substrate may be at capacity for additional weight — and the original waterproofing may predate current standards by two or three decades. Another tile-over in this situation can be the wrong call structurally, regardless of how the visible surface looks.
A tapware swap that surfaces a plumbing issue
In older properties, a simple tapware replacement sometimes exposes a plumbing configuration — corroded fittings, undersized supply lines, drainage that doesn’t meet current code — that requires correction before the new fixture can be installed compliantly. A licensed plumber identifies this at inspection. The right time to know is before contracts are signed, not after the old tapware is off the wall.
None of this means a refurbishment is the wrong scope for your bathroom — most bathrooms with a straightforward cosmetic brief are good candidates. But the starting point for any refurbishment conversation should include an honest look at the substrate condition, not just a discussion about which vanity to choose.
Licensing and Compliance — What Still Applies in a Partial Scope
NSW licensing requirements don’t scale down because the scope is described as a refresh. In NSW, any residential building work valued above $5,000 — labour and materials combined — must be carried out by a contractor holding an appropriate NSW Fair Trading licence. A refurbishment that includes tapware replacement, a vanity install, and a lighting update will routinely sit above that threshold. And importantly, the licence class has to match the work being done: a builder’s licence doesn’t cover plumbing connections; a plumbing licence doesn’t cover electrical. Each licensed trade is a separate obligation.
The trades most commonly involved in a refurbishment scope, and what licensing applies to each:
- Tapware replacement — any connection to the plumbing system requires a licensed plumber. This applies to basin mixers, shower roses, and bath spouts. It isn’t optional and it isn’t a job for a handyman, regardless of how straightforward the fitting looks.
- Lighting replacement — swapping a light fixture requires a licensed electrician, even where the circuit and fitting position stay the same.
- Tile resurfacing or partial re-tile — if existing tiles are lifted in the process and the waterproofing layer beneath is exposed or disturbed, a licensed waterproofer is required and AS 3740 compliance applies. What starts as a partial re-tile can become a waterproofing rectification scope once tiles come off.
- Vanity installation — the cabinet and basin can be installed by a carpenter or builder, but the plumbing connection to the basin requires a licensed plumber.
For contracts above $20,000, the contractor is required under NSW law to hold Home Building Compensation Fund (HBCF) insurance before work begins. Most refurbishments sit below that figure — but a mid-to-upper refurbishment that includes tiling, full fixture replacement, and licensed electrical and plumbing can approach it. Ask whether the contractor holds HBCF coverage if the quote is in that range. A contractor who hedges when asked about it is providing useful information, even if they don’t mean to.

Getting a Refurbishment Quote You Can Actually Compare
A refurbishment quote that presents a single lump-sum figure is nearly impossible to compare against a competing quote, and nearly as difficult to verify. You can’t tell what’s included, what’s been left out, or whether all the licensed trades the scope requires have actually been factored in. Itemisation isn’t just a preference — it’s the only way to compare two quotes that are genuinely covering the same job.
Labour separated from supply
The quote should show what you’re paying for labour and what you’re paying for materials — as separate lines. This makes it possible to compare quotes where you may be supplying your own fixtures, and gives you a clearer picture of where the cost actually sits.
Each trade as a separate line item
Plumbing labour, electrical labour, and tiling labour should each appear separately — not bundled under a generic “labour” line. Without that separation, you can’t confirm that all the required licensed trades have been properly costed in. A single labour line covering work that spans multiple licence classes should prompt questions before you sign.
Substrate assessment noted explicitly
If the scope includes any tiling work, the quote should note whether the substrate has been assessed — and what happens if tile removal reveals a compromised substrate. “We’ll deal with it if we find it” is not a contingency position. A quoted contingency allowance with a defined scope for what it covers is.
Waterproofing position stated clearly
If tiles are being lifted as part of the scope, the quote should confirm whether the existing waterproofing will be inspected and what the position is if it’s found to be deficient. This isn’t a formality — it’s the point where a refurbishment scope can become a rectification scope, with real cost implications. That conversation belongs in the quote, not mid-project.
Waste removal — included or excluded, stated explicitly
Disposing of an old vanity, toilet suite, tiles, and associated materials is a real cost. It should appear in the quote as either included or excluded — not left ambiguous. If it’s excluded, understand who is responsible for it and factor that into the comparison.
A quote that pushes back on itemisation — or presents a heavily discounted headline figure with no supporting detail — is telling you something. The most common cause of refurbishment budget blowouts isn’t scope creep from unexpected site conditions. It’s a quote that never included everything the job required in the first place.
Not Sure Whether Your Bathroom Needs a Refurbishment or Something More?
That question — refurbishment or full renovation — often can’t be answered from a description or a photo. It depends on what a proper scope assessment finds. Submit a quote request and a licensed specialist will be in touch within 48 hours to discuss your brief, establish what the bathroom actually needs, and give you a clear picture of cost and scope before any commitment is made. No obligation, no travelling sales representative.

Common Questions About Bathroom Refurbishment Costs
A refurbishment replaces what’s visible — fixtures, fittings, and finishes — without touching the structure, waterproofing system, or layout underneath. A renovation goes further: tiles come up, a new waterproofing membrane is installed to AS 3740 standard, and the scope can include layout changes or structural work. The practical test is simple. If tiles are being lifted, if plumbing points are moving, or if waterproofing is being opened, the job is a renovation regardless of what it’s called in the quote.
A basic fixture swap — vanity, tapware, and toilet suite with no tiling or structural work — typically runs $4,500 to $8,000. A more complete cosmetic refresh that includes partial re-tiling, a new shower screen, and a lighting update sits in the $9,000 to $15,000 range. These are directional industry estimates, not quotes. The condition of the existing bathroom, which trades the scope touches, material selection, and location all affect where a specific job lands. A quote conversation is the only way to get a number that applies to your bathroom.
In NSW, yes — and the licensing obligations don’t disappear because the scope is partial. Any residential building work valued above $5,000 (labour and materials combined) must be carried out by a contractor holding an appropriate NSW Fair Trading licence. Tapware connections require a licensed plumber. Lighting fixture replacement requires a licensed electrician. Using an unlicensed contractor above the $5,000 threshold is illegal, voids the statutory warranty that would otherwise apply under the Home Building Act 1989, and can affect insurance claims if a defect surfaces later.
Sometimes — but it’s not a blanket option, and it’s not a decision that should be made without assessing the existing substrate first. Tile-over is viable where the existing tiles are fully adhered with no hollow spots, the substrate is structurally sound, and the additional tile weight falls within structural tolerances. In homes where tiles have already been laid over the original substrate once before — which is common in Australian housing from the 1970s and 80s — another tile-over may not be appropriate. A tiler who quotes tile-over without inspecting the existing installation first is skipping a step that matters.
The items that disappear most often from lower-priced quotes are: a substrate assessment before any tiling work begins; waste removal for old fixtures and tiles; individual trade line items for plumbing and electrical work (often buried in a single labour line, which makes it impossible to confirm licensed trades have been costed); and a stated position on waterproofing if tiles are being lifted. A quote that bundles all of this into a single figure is hard to compare, harder to verify, and is where most refurbishment budget blowouts originate — not from unexpected site conditions, but from work that was never included in the first place.
