Bathroom renovation timelines: how the stages fit together

A bathroom renovation is not one long job. It is a chain of stages, each waiting on the one before it. The length of that chain depends less on how fast anyone works and more on decisions, deliveries and drying times. This guide sets out the order the stages run in and the four things that most often stretch or shorten the whole programme.

The order the stages run in

The sequence rarely changes, because each stage covers up the last. Once tiles are down, nobody can inspect the membrane, and once the vanity is fixed, moving a waste pipe means starting again. That is why the early paperwork stages matter as much as the building ones.

Our full renovation process explains each step in more detail.

01Consultation. The room is measured and the brief agreed: what stays, what moves and what the budget has to cover.

02Design & layout. Fixture positions, tile set-out and finishes are settled through bathroom design.

03Written quote. The scope is priced against the agreed selections, so ordering can begin.

04Strip-out. The old room comes out, exposing framing, floor and pipework for the first time.

05Waterproofing. Rough-in is completed, the substrate prepared and the membrane applied, see bathroom waterproofing.

06Tiling. Floor falls, walls, niches and grout, following the set-out drawn in the design stage.

07Fit-off. Vanity, tapware, toilet, screen, mirror and lighting are installed and connected.

08Handover. A final clean and walk-through before the room goes back into daily use.

Four things that set the pace

No two bathrooms follow the same calendar, so we don’t publish a standard duration. These are the factors that decide yours.

Selection lead times

Custom vanities, imported tiles and made-to-measure glass are ordered, not picked up. Finalising selections before strip-out means the room is never opened up while products are still on the way.

Membrane curing

Each membrane system has drying times between coats and before tiling, set by its manufacturer. Cold or damp weather can lengthen them. It is a wait worth respecting, because rushed membranes are a leading cause of leaks.

Trade scheduling

Plumbing, electrical, waterproofing, tiling and glazing each need their turn on site. When one stage runs over, the next trade’s booking moves too, so a single delay can ripple through the rest.

Behind the walls

Older Oakleigh, Hughesdale and Carnegie homes can hide rotted framing, uneven floors or tired pipework. These only show after strip-out, and fixing them properly comes before anything new goes in.

Keeping the programme moving

Most delays are decided before any tools arrive. A finished room like this one depends on the niche position, screen size and drain location being fixed on paper first, so the glass can be measured and ordered while the earlier stages run.

Confirm every selection before the strip-out date.

Agree how hidden issues will be raised and approved.

Plan where you will wash while the bathroom is out of use.

Avoid changing layout once rough-in has begun.
