Bathroom Renovation Timeline: What to Expect Week by Week

A standard bathroom renovation typically takes 1-3 weeks from strip-out to completion, depending on the scope of work, whether plumbing positions are changing, and whether the property runs into any unexpected issues once the old bathroom is opened up. Here's a realistic breakdown of what a professionally managed job usually looks like.

Days 1-2: Strip-out and first fix preparation

The old suite, tiles and flooring are removed, and the water and electrics are isolated. This is also when any unexpected issues tend to surface — old pipework in poor condition, damp behind tiles, or a floor that needs more preparation than expected. A good contractor will flag these early rather than partway through, since they can affect the rest of the timeline.

Days 2-4: First fix plumbing and electrics

New pipework and wiring is run to the positions needed for the new layout. If the layout is changing (moving the shower, adding a second basin), this stage takes longer than a like-for-like replacement. This is also when any Building Regulations-notifiable electrical work (Part P) needs to be carried out by a qualified electrician.

Days 3-5: Waterproofing and floor preparation

Waterproofing (tanking) around shower areas and any wet zones is applied and needs to properly cure before tiling begins — rushing this stage is one of the most common causes of leaks later. Floor levelling, if needed, also happens here.

Days 5-8: Tiling

Wall and floor tiling typically takes 2-4 days depending on the size of the room, the tile size and pattern (large format tiles are often quicker to lay than small mosaic-style tiles, but need a flatter surface), and whether any feature tiling or pattern work is involved. Grout then needs time to cure before fittings go in.

Days 7-10: Second fix — fitting the suite

The toilet, basin, bath or shower enclosure, taps and any accessories are fitted. This is when the room starts to look finished, though final testing and snagging still remain.

Days 9-11: Decorating and finishing

Painting, sealant (silicone) around joints, and final accessory fitting (mirrors, towel rails, shelving) happen last, once all the wet trades are complete. See our guide on how long bathroom silicone takes to dry for what to expect before the room can be used normally.

How to keep your renovation on schedule

A few practical steps help keep a bathroom renovation close to its planned timeline. Agree the exact fittings, tiles and finish before work starts rather than deciding as you go — mid-project decisions are one of the most common causes of delay, since ordering a tile or fitting partway through means everything after that stage waits for delivery. Order anything with a longer lead time (bespoke shower screens, certain tile ranges, specific sanitaryware) as early as possible, ideally before strip-out begins, so it's ready when the second fix stage arrives. Ask your contractor upfront what happens if strip-out reveals an unexpected issue — a clear plan for how additional work would be priced and scheduled avoids both delay and dispute if something does turn up.

What extends the timeline

• Moving the layout significantly (relocating the toilet or shower) adds several days for pipework changes.
• Unexpected issues found during strip-out — old damage, structural problems, or non-compliant existing work — can add days or more depending on severity.
• Waiting on bespoke or backordered fittings can hold up the second fix even if the rest of the job is on schedule.
• Access difficulties — a bathroom on an upper floor with a narrow staircase, or a property with restricted parking for skips and deliveries, can add time to even routine stages simply through slower material handling.
• Doing some work yourself around a job or other time commitments naturally extends the schedule compared with a dedicated professional team.

Budgeting for the disruption

For a family with only one bathroom, it's worth planning ahead for 1-3 weeks without normal access — whether that means arranging alternative washing facilities or scheduling the work around when it's least disruptive. It's also worth asking your contractor for a realistic estimate specific to your property's access and layout, rather than relying on a generic timeline, since the biggest swings come from site-specific factors rather than the work itself. See our full bathroom renovation cost guide and our comparison of DIY vs hiring a fitter if you're weighing up how much of the work to take on yourself, which affects both cost and timeline.
