The short answer
A typical bathroom installation takes 7 to 12 working days. A straightforward like-for-like refit can be at the shorter end, while moving fixtures, full tiling, a wet room or any complications push it longer. The job runs in a fixed sequence — strip-out, first fix, tiling, second fix, sealing — and waiting on deliveries or extra trades is the most common cause of delay.
One of the first questions homeowners ask is how long they will be without their bathroom. The honest answer is that most projects take roughly a week and a half of working days, but the exact figure depends on the scope. This guide sets out the typical timeline, the day-by-day stages and what stretches a job out.

The typical timeline
Most bathroom installations run over 7 to 12 working days. A like-for-like replacement — same layout, standard suite, part-tiled — sits toward the shorter end. Add full floor-to-ceiling tiling, relocate fixtures, build a wet room, or hit problems behind the old panels, and the job extends. Crucially, some stages need drying or curing time: adhesives, grout and tanking membranes cannot be rushed, which builds natural pauses into the schedule. Our cost guide and labour guide cover the trades involved.
| Stage | Typical days | What happens |
|---|---|---|
| Strip-out | 1–2 | Remove old suite, tiles, fittings |
| First fix | 1–2 | Plumbing and electrical in walls/floor |
| Plaster / tanking | 1–2 | Prep surfaces, waterproof where needed |
| Tiling | 2–3 | Wall and floor tiling, grouting |
| Second fix | 1–2 | Fit suite, taps, shower, electrics |
| Sealing & snagging | 1 | Silicone, final checks |
The day-by-day stages
The job follows a strict order. Strip-out clears the room back to the walls and floor. First fix runs the plumbing and electrical pipework and cables before surfaces are closed up. Plastering and, where needed, waterproof tanking prepare the surfaces — see our waterproofing guide. Tiling follows, then second fix installs and connects the suite, taps, shower and electrics. Finally the room is sealed with silicone and snagged. Our what to expect guide walks through the experience day by day.
What makes a job take longer
Several things stretch a bathroom out: moving the WC or soil stack (regulated drainage work), full tiling over part-tiling, building a wet room with full tanking, hidden problems uncovered at strip-out such as rot or dated wiring, and waiting on deliveries or specialist trades. Curing times for tanking and grout also add fixed pauses. Our wet room guide and en-suite guide cover the more involved projects. This page is general information; your timeline depends on the scope, your home and your chosen specialist.

Frequently asked questions
How long does a bathroom take to fit?
A typical bathroom installation takes 7 to 12 working days. A simple like-for-like refit is at the shorter end, while moving fixtures, full tiling or a wet room pushes it longer. Drying and curing times for tanking and grout add fixed pauses to the schedule.
Can a bathroom be fitted in a week?
A straightforward like-for-like refit can sometimes be completed in around a week of working days, but curing times and any complications often push it past that. Allowing 7 to 12 working days is more realistic for most projects.
Why is my bathroom installation taking longer than quoted?
Common reasons are waiting on deliveries, hidden problems found at strip-out such as rot or old wiring, a change of mind mid-job, and the unavoidable drying time for adhesives, grout and tanking. Ordering everything before work starts reduces delays.
Does a wet room take longer than a standard bathroom?
Yes. A wet room requires full waterproof tanking and a graded floor to the drain, plus curing time for the membrane, so it generally takes longer than a standard bathroom of similar size.
