10 / SEQUENCE & DURATION
How Long Does a Bathroom Renovation Take?
A bathroom is a short program with a lot of dependencies. Every stage waits on the one before it, and two or three of those waits are chemical rather than scheduled — no trade can shorten them. This guide walks the stages in order and explains what actually governs the length of each one.
01 / THE SHAPE OF THE PROGRAM
Short trades, long dependencies
Most of the individual trades in a bathroom are quick. What sets the overall duration is the order they must run in, the cure and set times built into the wet-area system, and how long it takes for the last selection to arrive on site. A renovation with everything chosen, ordered and delivered before demolition runs very differently to one where the tile is still being decided during rough-in.
Nobody honest will hand you a fixed number of days before seeing the room. Access, the state of the substrate behind the old tiles, apartment building rules and the lead time on your own selections all move the program. What follows is the sequence and the levers — not a promise.

02 / STAGE LEDGER
Each stage and what governs its duration
01 — Demolition and waste removal
Governed by access and disposal. A ground-floor room with a driveway strips out faster than a first-floor or apartment bathroom where every load travels by lift and booked dock time.
02 — Structural and substrate repairs
The unknown stage. Rotted framing, failed sheeting or an uneven slab only appear once the room is open, and repairs must be finished before any new sheeting or falls are set.
03 — Plumbing and electrical rough-in
Driven by how far services move. Keeping the layout puts pipes back near existing points; relocating a toilet or moving to a wall-hung basin means new runs, new penetrations and coordination between two trades.
04 — Sheeting and screeding
Wet-area sheeting goes up, then falls are formed to the waste. Screed needs to set before anything is applied over it, so this stage carries its own built-in pause.
05 — Waterproofing and cure
Bond breakers, corners and penetrations are detailed first, then coats are applied in sequence. Cure time between coats and before tiling is set by the product data sheet and site conditions — not by the schedule. Read the waterproofing guide or the membrane service page.
06 — Tiling and grouting
Usually the longest single stage. Large-format slabs, mitred edges, mosaic floors, niches and pattern set-outs all add hours, and adhesive must set before grout goes in. See bathroom tiling.
07 — Fit-off: fixtures and tapware
Toilet, basin, mixers, rail and waste are installed and tested. Quick work — provided every item is on site. A single missing mixer holds the whole fit-off open.
08 — Shower glazing (measured after tiling)
Glass is measured to the finished tiled surface, not to the frame, because walls are rarely perfectly plumb. That measure can only happen once tiling is complete, and fabrication then adds its own lead time. It is the most common reason a bathroom looks finished but is not. See walk-in showers.
09 — Joinery installation
Vanity, shaving cabinet and any tall storage are scribed and fixed, with stone tops templated to the installed cabinet where required. See vanity installation.
10 — Painting, silicone and final clean
Ceilings and any painted surfaces are cut in, junctions siliconed, then the room is cleaned and handed over with a defect walk-through. Silicone needs curing time before the shower is used.
WAIT 01
Membrane cure
Waterproofing coats cure to a schedule written by the manufacturer, affected by temperature and humidity. Tiling early over a green membrane risks the one failure that cannot be repaired without stripping the room.
WAIT 02
Screed and adhesive set
Falls have to set before membrane; adhesive has to set before grout; grout has to cure before the shower is used. These pauses are short individually and unavoidable collectively.
WAIT 03
Glass fabrication
Because the screen is measured after tiling, its fabrication window sits at the end of the program rather than inside it. Frameless and custom panels carry longer lead times than standard sizes.
03 / WHAT ACTUALLY CAUSES OVERRUN
Selections, not trades
The most common cause of a bathroom running long is not slow work — it is an item that arrives late. A discontinued tile, a stone slab that has to be re-selected, an imported mixer on back-order or a vanity in a finish that turns out to be a special order will all stall the stage that needs it, and every stage behind it.
Locking selections before demolition is the single biggest thing an owner controls. Confirm stock, order early, and keep a spare box of tile on site. The renovation checklist and materials guide set out what to decide first.

04 / LIVING THROUGH IT
Arrangements while the room is out
If the house has a second bathroom, most people stay put — dust protection, floor covering and a tidy site at the end of each day make that workable. If it is the only bathroom, plan for the full program rather than the tiling stage alone, because the room is unusable from demolition through to cured grout and silicone.
Apartments add another layer: lift bookings, approved work hours and building notice periods can compress the working day. That is factored into how a full bathroom renovation is programmed in buildings around South Yarra and Prahran.

05 / QUESTIONS
Timeline questions we are asked most
Can the waterproofing be rushed to save time?
No. Cure times belong to the product, not the program. Tiling over an uncured membrane is the fastest route to a leak that costs far more time later.
Why can't the shower screen be ordered earlier?
Glass is cut to the finished tiled opening. Ordering off framing dimensions risks panels that don’t seal, so the measure waits until tiling is complete and fabrication follows it.
Does keeping the existing layout shorten the job?
Usually, yes. Less plumbing and electrical relocation means a shorter rough-in and fewer coordination points, though the wet-area stages that follow are the same either way.
When will I know a realistic date range?
After the site assessment and once selections and their stock positions are confirmed. Before that, any figure is a guess — and the substrate condition behind the old tiles can still change it.
