How Long Does a Bathroom Installation Take?

How Long Does a Bathroom Refit Take?

The most common question homeowners ask before a bathroom project is how long they'll be without a working bathroom. Here are realistic timelines:

• Like-for-like swap (same layout, new fixtures) — 2–3 days
• Standard full refit (new suite, tiling, some layout changes) — 4–6 days
• Full bathroom renovation (new layout, plumbing rerouting, plastering) — 7–10 days
• Wet room (full tanking, gradient floor, frameless glass) — 7–12 days
• New en-suite from scratch (stud wall, new plumbing run, electrical) — 8–14 days

These are working days, not calendar days. Weekends and drying times are not included.

Day-by-Day Breakdown of a Standard Refit

• Day 1: Strip out — remove old suite, tiles, and flooring. Inspect subfloor and pipework.
• Day 2: First fix plumbing — reroute or extend supply and waste pipes. Lay new subfloor if required. Board walls ready for tiling.
• Day 3: Tiling — wall tiles fitted. Allow adhesive to set overnight before grouting.
• Day 4: Second fix plumbing — install bath, basin, toilet, and shower. Connect to waste. Grout tiles.
• Day 5: Finishing — fit accessories, sealant, flooring, radiator. Final checks and pressure test.

What Can Slow a Bathroom Project Down?

• Hidden damage on strip-out — rotten floorboards, failed waterproofing, or corroded pipework adds 1–2 days
• Tile adhesive and grout drying time — cannot be rushed without causing cracked or loose tiles
• Bespoke or long-lead items — some sanitaryware and tiles have 2–6 week lead times
• Replastering — wet plaster must dry fully (5–7 days) before tiling, which can pause the project
• Electrical work — if an electrician is needed for lighting or extractor fans, their availability affects the schedule

How to Keep Your Project on Schedule

• Have all materials and fixtures on site before work starts — don't wait for deliveries mid-project
• Agree a scope of works in writing with your plumber before day one
• Ask your plumber to inspect the existing pipework before stripping out, where possible
• Choose tiles that are in stock rather than special order
• Book a second bathroom (or temporary shower) in advance if you only have one

Why Timescales Vary

The time required to complete a bathroom installation is one of the most common questions homeowners ask, and also one of the hardest to answer without knowing the specifics of the project. A basic bathroom refresh with new sanitaryware in an existing layout is a very different undertaking from a full bathroom conversion involving new plumbing routes, underfloor heating, and bespoke tiling.

Factors That Extend a Bathroom Installation

Several variables can push a bathroom project beyond the baseline timeline. Layout changes that require moving soil pipes or relocating the soil stack are the most time-consuming — moving a WC to a different wall, for example, can add two to three working days. Installing underfloor heating before tiling adds roughly a day. Plastering after removing old tiles takes 24–48 hours to dry before tiling can begin, which stretches overall programme length even if working days remain similar. Properties with solid concrete floors require different methods for routing waste pipework compared to properties with suspended timber floors, and concrete can slow progress significantly.

Wet Rooms vs Standard Bathrooms

Wet room installations typically take longer than standard bathroom replacements because the waterproofing membrane must be applied to the entire floor and shower walls and allowed to cure fully before any tiling begins. For a full wet room conversion with a linear drain, allow an extra two to three days compared to a conventional shower enclosure installation. Wet rooms in Peterborough's older housing stock — where floors may not be level and joists may need reinforcing to carry the additional weight of the screed — can take even longer to prepare correctly.

What Happens on Each Day

Day 1 is typically strip-out: removing the existing suite, tiles, and flooring, and checking pipework condition once exposed. Days 2–3 cover first-fix plumbing — running new supply and waste pipes to the new layout. Days 4–5 are often tiling and boarding. Days 6–7 cover second-fix: fitting the new suite, installing shower enclosures or screens, and connecting all fixtures. A final day covers snagging, sealing, grouting touch-ups, and customer sign-off. Your installer should give you a day-by-day programme before work begins so you can plan around the disruption.
