Bathroom Renovation Timelines

How long a bathroom renovation takes depends less on the tiler and more on the order of work. Every job moves through the same seven stages, and each one has to finish before the next can start. A membrane can’t be laid over wet render, and a vanity can’t go in before the wall is tiled. This guide walks through those stages in sequence and shows where time is usually gained or lost, so you can plan the rest of your household around the work.

SHEET A — ON PAPER

The stages that save the most time happen before demolition

Design

This is where the layout is settled: where the shower, toilet and vanity sit, whether the drainage moves, and how the door and window work with the room. Moving a waste pipe on paper costs nothing. Deciding to move it once the floor is open holds up everything after it. Our Bathroom Design service is where layout decisions are settled before building starts.

Selections

Tapware, the shower mixer body, floor waste, niche size, tiles, vanity and screen. Some of these have to be on site before rough-in, because the plumber sets pipe positions to the exact product. Lead times for imported tiles and custom vanities vary a lot, so the sooner the schedule is confirmed, the fewer gaps open up later. The Renovation Checklist sets out what to choose, and in what order.

SHEET B — ON SITE

Five trades, one strict order

Once work starts, each stage depends on the one before it. When one stage runs long, everything after it moves too, so the dates of later trades should be treated as provisional until the earlier work is signed off.

Demolition and rough-in

The room is stripped back to the frame and slab. This is the moment older St Kilda flats and terraces show what’s hidden: rotten sub-floor, out-of-plumb walls or old leaks. The plumber and electrician then run new pipes, wastes and wiring to the positions set in the design.

Waterproofing

Screeds are laid to fall, then the membrane goes on in coats. Each coat needs the curing time set by the product manufacturer, and rushing it is the most common cause of failure later on. Read more on Waterproofing.

Tiling and fit-off

Large-format and patterned tiles take longer to set out than plain ones. After grouting, the trades come back to fit the tapware, toilet, vanity, screen and lighting, then seal and clean. More detail on Bathroom Tiling.

SHEET C — VARIABLES

What stretches a timeline

— Late selections. A mixer or tile that isn’t chosen by rough-in stops the stages that follow.

— Layout changes. Moving a shower or toilet means new drainage and may need extra floor work.

— Hidden conditions. Water damage or failed sub-floors only show up once the old room is removed.

— Building access. Apartments with owners corporation rules, lift bookings or limited work hours slow deliveries and removal.

— Scope. A small bathroom refresh and a full strip-out are very different sequences.

Many of the same variables drive price too. The Bathroom Renovation Cost Guide explains how.
