How Long Does a Full Bathroom Renovation Take?

The short answer: two to three weeks on site

For a standard family bathroom of around 2m x 2m, most full renovations take 10 to 15 working days once work starts. That covers stripping the old suite, first fix plumbing and electrics, plastering, tiling, fitting the new suite and finishing off. A small cloakroom might be done in a week; a large bathroom with underfloor heating, a walk-in shower and full height tiling can stretch to four weeks.

The on-site time is only part of the story. Add two to six weeks beforehand for design decisions, ordering and lead times on sanitaryware and tiles. Booking a fitter in Surrey often means a wait of several weeks too, so from first quote to finished room, two to three months is a sensible overall expectation.

A week by week breakdown

Every job varies, but a typical full renovation follows the same sequence. The order matters because plaster and adhesive need drying time, and electrics must be signed off before boarding over.

Here is how the days usually fall on a standard bathroom:

• Days 1 to 2: strip out the old suite, tiles and flooring, and deal with any surprises behind them
• Days 3 to 5: first fix plumbing and electrics, moving pipework or wiring for showers, lighting and extractor fans
• Days 5 to 7: boarding, tanking wet areas and plastering, with drying time before tiling
• Days 8 to 11: wall and floor tiling, then grouting once the adhesive has cured
• Days 12 to 14: second fix, meaning the bath, basin, toilet and shower go in, plus sealant, lighting and accessories
• Final day: snagging, testing everything under pressure and a full clean

What makes a renovation take longer

The biggest cause of delay is what turns up during strip out. In older properties around Addlestone, Weybridge and Chertsey, it is common to find rotten floorboards under a leaking bath, crumbling plaster behind tiles, or old lead and imperial pipework that needs replacing. None of these are disasters, but each can add two or three days and it is worth having some contingency in both budget and diary.

Product lead times are the other regular culprit. Standard suites from the big merchants arrive within days, but made-to-order vanity units, bespoke shower enclosures and imported tiles can take four to eight weeks. A good fitter will not start the strip out until everything is on site, because a half-finished bathroom waiting on a shower screen helps nobody.

Structural or layout changes add time too. Moving the toilet means altering soil pipe runs, which can add several days. Converting a bathroom to a wet room involves tanking the whole floor and forming falls to a drain, typically adding a week.

How to keep your project on schedule

Most overruns are avoidable with decisions made early. Choose your suite, tiles, brassware and flooring before work is booked in, and have everything delivered and checked before day one. Damaged tiles discovered mid-job are a frustratingly common cause of a stalled second week.

It also pays to agree the small details up front: exactly where the shower controls sit, which way the door on the vanity opens, where the towel rail and shaver socket go. Changing your mind after first fix means redoing pipework or chasing walls again, and that is where days quietly disappear.

Finally, ask your contractor for a written schedule showing the trades involved and when the water will be off. A well-run job only needs the water off for short periods, and you should have a working toilet at the end of each day wherever possible.
