How Long Does a Bathroom Installation Take in the UK?

Bathroom Timelines — What's Realistic for Your Project

The first question almost every homeowner asks before a bathroom installation is how long they'll be without a working bathroom. The honest answer depends on the scope of the work. Here are the realistic timelines for every project type — and the factors that most commonly push them over schedule.

Like-for-Like Swap: 1–3 Days

Replacing a toilet, basin, or bath in the same position without moving any pipework is the fastest possible bathroom job. If all three are replaced but the layout stays identical, most standard suites are installed in 1–3 working days with minimal disruption.

Standard Full Refit: 4–6 Days

A full bathroom refit — new suite, new tiles, minor plumbing changes — takes most professional teams 4–6 working days. This is the most common project in Peterborough homes. Day 1 is strip-out and first fix plumbing. Days 2–3 cover boarding and tiling. Days 4–5 are second fix plumbing and finishing. You'll have limited bathroom access throughout, so a second toilet is useful if you have one.

Layout Changes or Replastering: 7–10 Days

Moving the toilet or bath to a different wall requires rerouting soil and supply pipes — adding 1–3 days. If walls need replastering, add another 5–7 days drying time before tiling can begin. Wet plaster cannot be rushed without producing cracked tiles later.

Wet Room: 7–12 Days

A wet room requires full tanking, a graded screed, and careful tile installation — and each layer must cure before the next can begin. Allow 7–12 working days minimum. See our comparison of wet rooms vs shower enclosures if you're still deciding which option is right for your bathroom.

New En-Suite from Scratch: 8–14 Days

Adding a new en-suite requires stud walling, new plumbing runs, electrical work for lighting and extraction, plastering, and a full suite installation. Co-ordinating the plumber, plasterer, tiler, and electrician typically adds days to the schedule.

What Causes Delays

The most common causes of bathroom projects running over are: hidden damage found on strip-out (rotted floorboards, failed waterproofing, corroded pipework), materials not on site when work begins, and trades not properly co-ordinated. Having all tiles, sanitaryware, and fittings delivered before day one is the single most effective way to keep a project on track.
