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 Sydney
An ensuite renovation in Sydney is costed high per square metre precisely because it is small, since a compact bathroom off a bedroom still needs the full wet-area build, the waterproofing membrane, the tiling, the plumbing rough-in and the fixtures, all crammed into a few square metres where the fixed costs do not shrink with the room. So a tiny ensuite can cost nearly as much as a bigger main bathroom, because the shower, vanity and toilet each carry their own plumbing and the whole floor and walls must still be waterproofed and tiled.
The waterproofing is the critical, licensed element, as the membrane must be laid to the Australian standard under the tiles, and in an upstairs or strata Sydney apartment a leak into the room or unit below makes it non-negotiable. Carving a new ensuite into a bedroom in a terrace or period home adds the cost of new plumbing runs to reach the room and sometimes a new wall. The fixtures and finishes, from a basic suite to a stone-top vanity and frameless shower screen, swing the figure widely. The city's highest trade rates lift the labour, and the tight space means trades work in sequence, which can stretch the timeline on a small job.
An ensuite renovation is licensed work: the waterproofing by a licensed waterproofer or tiler, the water and drainage by a licensed plumber, and any lighting or heated towel rail by a licensed electrician, in New South Wales under NSW Fair Trading. For a Sydney home, the clearest way to price an ensuite renovation is by the full wet-area fit-out packed into a small room, with waterproofing the critical element and fixtures swinging the figure.
