How much does a bathroom renovation cost in Perth?
For a Perth bathroom taken back to bare walls and rebuilt with entry-level fittings, our table shows $10,500–$21,000, with $15,750 the usual figure. Stepping up to better tapware, tiles and a frameless screen moves the job to $21,000–$36,750, and premium finishes to $36,750–$57,750. Locals often search for budget work, and the honest answer is that the cheap end still pays for the same hidden layers: demolition, a new membrane and the plumbing rough-in. Perth houses run large, so many owners are pricing an ensuite too, which on its existing layout comes to $15,750–$31,500. All figures include GST.

What each tier actually includes
Northern Suburbs
Joondalup, Wanneroo, Duncraig, Hillarys. Mix of 1980s–2000s homes with standard bathroom layouts and good access. Concrete slab construction simplifies waterproofing. Competitive local trade rates. These suburbs represent Perth's most predictable renovation costs — few surprises behind the walls.
Southern Suburbs
Rockingham, Mandurah, Baldivis, Armadale. Most affordable area for bathroom renovators in Perth. Newer homes (2000s–2020s) with builder-grade bathrooms that need cosmetic upgrading rather than structural work. The high volume of similar homes creates efficiency for renovators, keeping costs competitive.
Eastern & Hills Suburbs
Kalamunda, Mundaring, Midland. Established homes on larger blocks, some with access challenges that increase trade costs. Hills properties may have additional plumbing complexity due to elevation. Older homes (1960s–80s) in these areas can hold surprises — check for termite damage and outdated plumbing before finalising renovation budgets.
Standard full renovation — mid-range
Complete strip-out: demolition ($1,050–$3,150), plumbing rough-in ($2,100–$5,250), electrical, waterproofing to AS 3740 ($735–$3,675), floor and wall tiling ($2,950–$7,900, tiles included), vanity ($525–$3,675), toilet ($420–$1,250), shower screen ($840–$2,625), tapware. Timeline: 3–5 weeks. Perth's most common renovation scope — the slab-on-ground construction typical of WA homes makes waterproofing more straightforward than in raised timber-floor homes.
Premium bathroom — high-end finishes
Layout changes, premium porcelain or natural stone tiles, a freestanding bath ($1,575–$5,250), a wall-hung vanity with stone top, a frameless shower screen ($840–$2,625), premium tapware (Brodware, Sussex, Astra Walker), underfloor heating, LED niches, and a heated towel rail ($370–$1,250). Perth's dry climate means underfloor heating is less essential than in Melbourne but still popular for winter mornings.
Second bathroom addition
Converting a laundry, storage room, or section of a bedroom into an additional bathroom. Includes all new plumbing (a plumbing rough-in alone is $2,100–$5,250), electrical, waterproofing, tiling, fixtures, and potentially structural work. This is a common project in older Perth homes that were built with only one bathroom, and a second bathroom can add to a 3-bedroom home's value in Perth's market.
Budget bathroom renovation cost in Perth (2026): what a cheap, mid-range and premium reno buys
A budget bathroom renovation in Perth costs $10,500–$21,000, with $15,750 typical: the existing layout kept, budget fittings, standard tiles, and the plumbing and waterproofing done properly. A mid-range renovation is $21,000–$36,750 and a premium one $36,750–$57,750. The jump between tiers is mostly fittings, tiles and whether the layout moves.
| Job | Low | Typical | High |
|---|---|---|---|
| Basic renovation (budget fittings) | $10,500 | $15,750 | $21,000 |
| Mid-range renovation | $21,000 | $28,350 | $36,750 |
| Premium renovation | $36,750 | $44,100 | $57,750 |
| Demolition & disposal | $1,050 | $1,900 | $3,150 |
| Waterproofing | $735 | $1,475 | $3,675 |
| Tiling, supply and lay (floor + walls) | $2,950 | $5,250 | $7,900 |
| Vanity (supply + install) | $525 | $1,575 | $3,675 |
| Toilet (supply + install) | $420 | $735 | $1,250 |
| Shower screen (frameless) | $840 | $1,575 | $2,625 |
Where a cheap bathroom renovation in Perth saves and where it cannot: the savings are in the fittings (a $525 vanity instead of $3,675, a framed shower screen instead of frameless at $840–$2,625), standard-size tiles and keeping the toilet, shower and vanity where they are so the plumbing stays put. Demolition ($1,050–$3,150), waterproofing ($735–$3,675) and tiling ($2,950–$7,900) are the same job whatever the budget, and waterproofing is the one line never to cut: a failed membrane is the most expensive bathroom fault there is.
What moves a bathroom renovation quote in Perth:
- Layout: moving the toilet or shower means new drainage through the slab or floor; keeping the layout is the biggest single saving.
- Size: a larger bathroom is more tiles, more waterproofing and more labour.
- Tiles: floor-to-ceiling, large format or feature tiles add material and laying time over a standard height in a standard size.
- Fittings: tapware, vanity, toilet and screen each span a wide price range at the same quality of installation.
- What is found: an older Perth home can hide rotten framing, old waterproofing or asbestos sheeting behind the tiles, all priced once uncovered.
For a renovation quote that holds, give the builder the room size, whether the layout changes and the tier of fittings you want; Perth renovators price the bands above from that.
What Affects Bathroom Renovation Costs in Perth
Where a budget job stops
A budget renovation keeps the layout and pairs a standard vanity with plain tiles; much of its band goes on labour that every tier shares. Mid-range pays for nicer tiles and tapware plus a frameless screen, premium adds stone tops and a freestanding bath, and a luxury fit-out reaches $57,750–$84,000. If money is tight, keep every fixture in its current spot and spend on the membrane rather than the taps.
Big houses, two wet rooms
Perth homes run roomy: 45.7% have at least four bedrooms, next to 34.8% Australia-wide, and detached houses make up 77.8% of the city's housing (ABS 2021 Census). Bigger homes often have a second wet room off the main bedroom. Refitting a 3 to 5 m² ensuite without moving anything is $15,750–$31,500, and pricing both rooms on one quote lets a single crew share the strip-out and trade visits.
Written contract, 6.5% deposit
WA home building contracts priced from $7,500 up to $500,000 at a fixed cost fall under the Home Building Contracts Act, whether or not the builder is registered, and every renovation tier in our table sits inside that range. The contract has to be in writing and signed by both parties, 6.5% is the ceiling on any deposit, and progress payments may only cover work actually done.
Registration and indemnity cover
Most work worth $20,000 or more that needs a building permit must be carried out by a builder on the Building and Energy register. When a permit is needed and the value tops $20,000, home indemnity insurance, taken out in your name, is compulsory too, protecting a lost deposit up to $40,000 and incomplete or defective work up to $200,000. A typical mid-range job sits above that value ($28,350), so ask whether yours needs a permit.
Wet winters, bone-dry summers
July is the wettest month at the Perth Metro gauge, with 147.0 mm on average, while December gets 9.6 mm (BOM averages), and the city lies in NCC climate zone 5. Winter is when a bathroom with a weak exhaust fan stays damp and grows mould on the ceiling, so ask for a fan ducted to the outside. Membranes, adhesives and grout also cure more slowly in cool, wet weather, which can add time to a winter job.
Membrane, tiles and fittings
The National Construction Code makes waterproofing compulsory in wet areas, and the membrane here costs $735–$3,675; a failed one is redone in full, never patched. Tiling the floor and walls, materials included, adds $2,950–$7,900. Fittings follow: vanity $525–$3,675, frameless screen $840–$2,625, freestanding bath $1,575–$5,250, toilet $420–$1,250 and a warm towel rail for $370–$1,250.
Plumbers and old wall sheeting
Apart from small tasks such as repairing a tap, which an occupier can do or have done unpaid, every other water, sanitary or drainage job in WA belongs to a licensed plumber or a permit-holder. Budget $2,100–$5,250 for the rough-in before any fixture moves. Stripping the room is $1,050–$3,150; if older sheeting turns out to hold asbestos, the state's advice is a licensed removalist and a clearance certificate afterwards.
How to Save Money on Bathroom Renovation Cost in Perth
Larger ensuites and walk-in setups in Perth
Perth bathroom renovations support larger footprints than east-coast equivalents due to bigger block and house sizes. Premium ensuite work in Cottesloe, Subiaco, and Mosman Park ($25,000–$50,000) commonly includes walk-in setups with twin vanities. Standard main-bathroom work in Joondalup, Wanneroo, and Morley estate homes sits at $14,000–$25,000. Coastal salt-zone fittings (Hillarys, Scarborough) need stainless tapware and frameless glass with corrosion-resistant hardware.
Perth's hard water (high mineral content) shortens lifespan of standard chrome tapware — local renovators steer toward solid brass or stainless cartridge taps. Worth confirming a contractor specifies these as default rather than cheapest-option chrome. The price difference is small at install; the failure-rate difference is large at year 3.
