Your estimate sits within the typical range.
An ensuite costs almost as much as a main bathroom despite being smaller, because waterproofing, plumbing and tiling are fixed jobs regardless of size. Keeping the layout and choosing finishes wisely are the main levers.
Ways to save
- Keep the existing layout, moving plumbing is the biggest avoidable cost.
- Use mid-range tiles with one or two statement pieces to get a premium look for less.
- Get waterproofing done properly by a licensed waterproofer, a leak later costs far more than the saving.
How we estimate this
An ensuite renovation in Australia typically costs around $12,000 to $20,000 for a mid-range full renovation in 2026, with budget refreshes lower and premium fitouts $30,000 or more. Moving plumbing and high-end fixtures add to that.

What a ensuite renovation costs in Perth
In Perth the rate per square metre for an ensuite is steep, and the reason is that shrinking the room does not shrink the build: a little bathroom off a bedroom still demands the same waterproof membrane, the same tiling, the same plumbing rough-in and the same suite of fittings, all squeezed into a handful of square metres that carry every one of those fixed costs. That is why a pocket-sized ensuite lands close to a full main bathroom in price, with each of the shower, basin and toilet bringing its own pipework and the entire floor and walls needing the membrane and tiles regardless.
Perth's common double-brick construction shapes the job, because chasing new plumbing and relocating fixtures through solid double-brick walls to carve or reconfigure an ensuite is more involved than in a timber-framed home, adding labour. The waterproofing is the critical, licensed element, laid to standard under the tiles. The dry Mediterranean climate means mould pressure in the small room is lower than in the humid north, though an exhaust fan is still fitted. The fixtures and finishes swing the figure, from a basic suite to premium tiling and a frameless screen. The isolation of the WA market can add lead time for a specialist fitting, and labour sits near the national average on this small but intensive job.
Several licensed trades touch the job in Western Australia under WA Building Services: a licensed waterproofer or tiler seals the wet area, a licensed plumber runs the water and drainage, and a licensed electrician wires any downlight or heated rail. For a Perth home the number comes down to a complete wet-area fit-out crammed into a tiny footprint, with the double-brick plumbing chase and the certified membrane the costs that matter most.

Frequently asked questions
Why does a small ensuite cost so much in Perth?
Because a compact bathroom still needs the full wet-area build, the waterproofing, tiling, plumbing rough-in and fixtures fitted into a few square metres where the fixed costs stay fixed, so a small Perth ensuite approaches the cost of a larger bathroom.
Does double-brick affect a Perth ensuite?
Yes. Chasing new plumbing and relocating fixtures through solid double-brick walls to carve or reconfigure an ensuite is more involved than in a timber-framed home, which adds labour to a Perth ensuite.
Does the dry climate help a Perth ensuite?
A little. The dry Mediterranean climate means mould pressure in the small room is lower than in the humid north, though an exhaust fan is still fitted and the waterproofing laid to standard remains the critical element in a Perth ensuite.
Do I need licensed trades for a Perth ensuite?
Yes. The waterproofing is a licensed waterproofer or tiler's job, the water and drainage a licensed plumber's, and any lighting or heated towel rail a licensed electrician's, in Western Australia under WA Building Services.
