How a Sydney bathroom renovation runs, week by week
Strip-out, rough-in, waterproofing, tiling, fit-off and handover. What good looks like at each stage, how long it takes, and why the membrane has to cure before the tiles go on.
Short answer: A bathroom is built in a fixed order, and the order cannot be rushed. Strip-out, rough-in, waterproofing and cure, tiling, then fit-off and handover. The week that looks like nothing is happening is usually the week that matters most.
The sequence, stage by stage
Every renovation runs through the same stages in the same order, because each one depends on the one before it. Knowing the sequence means you can tell real progress from a job that has stalled.
Strip-out. The old bathroom comes out to the frame. This is fast and dramatic, often a day or two, and it is where any hidden damage behind the old tiles shows up.
Rough-in. Plumber and electrician set the pipes, drains and wiring in the walls and floor for the new layout. Once tiles go on, these are locked, so this stage is where the layout becomes real.
Waterproofing and cure. A licensed waterproofer applies the membrane to the floor and wet walls, then it cures. Slow on purpose.
Tiling. Floor and walls are tiled, then grouted. The largest visible stage, and the one most affected by the quality of the prep underneath.
Fit-off. Vanity, toilet, tapware, screen and accessories go in. The room starts to look finished in a couple of days.
Handover. Final clean, a walk-through with you, the waterproofing certificate, and the written warranty.

The on-site clock includes the cure. A builder who skips it is buying speed with your walls.
What good looks like on the day
A tidy site is a sign of a tidy build. Tools put away, off-cuts cleared, the rest of your home protected with drop sheets and dust barriers. Falls to the drain checked with a level before tiling. Tiles set out so the cuts land in sensible places, not awkward slivers at eye height. None of this costs more. It just takes care.
Confirm before day one
Get the start and handover dates in writing, and ask how delays are handled.
Confirm which days the bathroom is fully off line so you can plan around it.
Confirm the licensed waterproofer and that the cure time is built into the program.
!Careful
If a builder promises a full bathroom in under three weeks, ask where the waterproofing cure fits. Either the membrane is being rushed or the program is optimistic. Both end the same way.
Common questions
How long does a Sydney bathroom renovation take?
A standard main bathroom is about five to seven weeks on site, plus four to six weeks of design and selections beforehand. The on-site weeks are not all visible progress. Several days go to waterproofing and curing, where nothing appears to happen but the most important layer is being built. A good builder gives you specific start and handover dates in writing.
Why does the waterproofing have to dry before tiling?
The waterproof membrane is the layer that keeps water out of your walls and floor for the next twenty years. It needs its full cure before tiles go on, often a day or two per coat depending on the product and the weather. Tiling over a membrane that has not cured is the single most common cause of a bathroom that leaks within a few years. The wait is not padding. It is the job.
Can I use the bathroom while it is being renovated?
No. From strip-out to handover the room is a building site with no working fixtures for several weeks. Plan a second bathroom in the house, or a temporary arrangement, before work starts. We confirm the off-line dates with you at the start so there are no surprises.
