What a bathroom renovation costs in Perth
A full bathroom renovation in Perth, the main bathroom with a bath, shower, vanity and toilet, is priced on the wet-area rebuild: the waterproofing membrane, the floor and wall tiling, the plumbing, and the fixtures, with the largest variable being whether the layout is kept or the fittings are moved. Keeping the plumbing where it is holds the cost down, while relocating the bath, shower or vanity needs new pipe runs, so the layout choice sets the figure before the finishes.
Perth's common double-brick construction shapes the job, because moving fixtures or reconfiguring the room means chasing new plumbing through solid double-brick walls, which is more involved than in a timber-framed home and adds labour. The waterproofing is the critical, licensed element, laid to standard under the tiles. The dry Mediterranean climate means mould pressure is lower than in the humid north, though an exhaust fan is still fitted. 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, with a main bathroom larger than an ensuite so there is more tiling.
A bathroom renovation is licensed work: the waterproofing by a licensed waterproofer or tiler, the water and drainage by a licensed plumber, and any lighting, fan or heated rail by a licensed electrician, in Western Australia under WA Building Services. For a Perth home, the clearest way to price a full bathroom renovation is by the waterproofing and tiling, the plumbing, and whether the layout moves, with double-brick plumbing chasing a factor.
