If you are asking how long does a bathroom renovation take, the short answer is one to three weeks for most UK homes. The exact number depends on the size of your room and the scope of the work. This guide breaks down every stage so you know what to expect.
At ABL Design & Build, we get this question on almost every call. Below you will find a full week by week timeline, the factors that change it, and honest advice from our own site experience.
Homeowners across London ask us how long does a bathroom renovation take before they even ask about price. We think that is the right order of questions, so let’s start there.
Quick Answer: Average Bathroom Renovation Duration
Not every bathroom job takes the same time. Before you look at the day-by-day breakdown below, here is a quick comparison of the four most common project types we see across London.
Timeline by Project Type
| Project Type | Typical Duration | Rough Cost Range | What’s Included |
|---|---|---|---|
| Refresh | 5 to 8 working days | £3,500 – £6,500 | Like-for-like swap. Toilet, basin, and shower stay in the same position. New suite and re-tiling over existing layout. No pipework changes. |
| Full Refit | 10 to 15 working days | £7,000 – £12,000 | Full strip-out, new plumbing runs, full wall and floor tiling, new suite, new extractor fan. Minor layout tweaks allowed. |
| Layout Change | 15 to 20 working days | £11,000 – £17,000 | Toilet or basin moved to a new position, new pipework routing, possible stud wall changes, larger format tiles, upgraded shower valve. |
| Wet Room / Luxury Suite | 20 to 30 working days | £16,000 – £30,000 | Tanked wet zone, linear drain, bespoke tiling, frameless glass screen, freestanding bath, underfloor heating, and full electrical rewire. |
These figures cover on-site working days only. Planning, design sign-off, and material lead times happen before day one, so always add this to your overall project timeline.
This is the real average bathroom renovation duration across hundreds of UK jobs we have reviewed and worked on. A bigger ensuite, a wet room conversion, or an older period property can push the timeline past three weeks. Below, we walk through the full bathroom renovation process stage by stage.
People rarely ask us just once how long does a bathroom renovation take. They ask again once they see the quote, and again once work starts. That is normal. Timelines shift a little on every real project, and a good contractor will tell you why, not just promise a fixed date and hope for the best.
Same Layout vs New Layout
Keeping your toilet, basin, and shower in the same spots is the fastest route. Moving pipework and waste runs adds several days to any project. If someone asks how long does it take to renovate a bathroom without changing the layout, the honest answer is often just five to eight days.
The Bathroom Remodel Timeline, Stage by Stage
Here is our bathroom remodel timeline based on real jobs across London. This covers a standard three by two metre bathroom with a shower, bath, toilet, and basin.
Day 1: Demolition
Demolition clears out your old suite, tiles, and flooring. This is the loudest and dustiest day of the whole job. We protect the rest of your home with dust sheets and sealed doorways before we start.
By the end of day one, the room is stripped back to bare walls and floor. This gives our team a clean base to check pipework and wiring before moving forward.
Days 2 to 4: First Fix and Plumbing Installation
This stage covers the work behind the walls. Plumbing installation includes new pipe runs, waste connections, and any repositioning of the toilet or shower. Electricians also run cables for extractor fans, lighting, and shaver points.
If you are keeping the current layout, this stage moves fast. If you want a new position for the shower or basin, budget extra time here. This is usually the stage that decides how long to fit a bathroom overall.
Days 4 to 5: Waterproofing and Boarding
Walls get boarded with moisture resistant panels, then sealed with a waterproof membrane. Skipping this step is the top cause of leaks and cracked tiles further down the line. We never rush this stage, even under a tight deadline.
Days 5 to 9: Tiling
Tiling is often the longest single stage of the entire project. Tilers set the walls and floor, then leave the adhesive to cure before grouting. Large format tiles, herringbone patterns, and full height walls all add extra days to this stage.
Choosing simple, standard size tiles is one of the quickest ways to shorten your bathroom renovation stages. Complex patterns look great, but they do take longer to lay well.
Days 9 to 12: Final Fixtures and Fittings
Now the room starts to feel finished. Final fixtures and fittings include the toilet, basin, taps, shower screen, radiator, and bath. Sealant goes in around the edges, and every fitting is tested for leaks.
This stage also covers mirrors, shaver sockets, and any storage units. Once everything passes testing, we move to the final clean and handover walk through with you.
Days 12 to 15: Snagging and Handover
The last few days cover small fixes, paint touch ups, and a full deep clean. We walk the room with you to check every detail before we call the job done.
How Long to Refit a Bathroom vs a Full Renovation
People often ask how long to refit a bathroom compared to a complete renovation. A refit usually means replacing the suite and tiles without changing pipework or layout. This can be finished in five to eight working days.
A full renovation, with new plumbing, a different layout, or structural work, needs closer to two to three weeks. If you are asking how long does it take to do a bathroom renovation on an older property, always add a few extra days for surprises behind old walls.
What Speeds a Project Up or Slows It Down
A few factors control the real timeline more than anything else. Based on the jobs we run across London, here is how often each one actually shows up, and how many days it typically adds.
Tile or material lead-time delays: appears in roughly 60% of jobs, adds 3 to 5 days
Bespoke, imported, or large format tiles are the single biggest cause of delay we see. If it is not in stock and on site before day one, the tiling stage stalls until it arrives.
Hidden pipework or structural issues: appears in roughly 35% of jobs, adds 2 to 4 days
Period properties across London often hide old lead pipework, rotten joists, or uneven subfloors behind the old suite. This only becomes visible once demolition is done.
Client-driven changes mid project: appears in roughly 25% of jobs, adds 2 to 3 days
Swapping a tile colour, a tap finish, or a fitting after work has started means reordering and reworking a stage that was already finished.
Layout changes: appears in roughly 20% of jobs, adds 3 to 7 days
Moving the toilet, shower, or basin means new pipework and waste runs, which is one of the largest single additions to any timeline.
Access restrictions: appears in roughly 15% of jobs, adds 1 to 2 days
Second floor bathrooms, narrow staircases, or limited parking for deliveries in central London can slow down materials reaching the site.
Weather and curing time: appears in nearly every job, adds 1 to 2 days
Grout, adhesive, and sealant all need proper curing time. This is not a delay we can remove, it is simply part of doing the job properly.
Knowing which of these applies to your home before work starts is the easiest way to get an accurate timeline instead of a guess.
A few factors control the real timeline more than anything else:
- Layout changes. Moving the toilet or shower adds days for new pipework.
- Material availability. Order tiles, taps, and your suite before work starts.
- Property age. Period homes in London often hide old pipework or uneven walls.
- Tile choice. Large format and patterned tiles take longer to lay and cure.
- Access. Second floor bathrooms or narrow staircases can slow deliveries.
- Weather and drying times. Grout, adhesive, and sealant need proper curing time. This cannot be rushed without risking the final finish.

Common Mistakes That Extend the Timeline
Even simple projects can run late when a few small mistakes happen early on. We see the same issues come up again and again on site.
- Changing your mind mid project: Swapping a tile or fitting after work starts causes delays and reorders.
- Ordering materials too late: Popular tiles and suites can take two to three weeks to arrive.
- Skipping a proper survey: Old pipework and uneven floors are easier to plan for than fix on the fly.
- Choosing the cheapest quote without checking the schedule: Ask exactly how long does a bathroom renovation take with that specific contractor, in writing, before you sign anything.
Avoiding these mistakes is one of the simplest ways to protect your bathroom renovation stages from running over.
Do You Have to Move Out During Work?
Most homeowners stay in their home during a bathroom renovation. From the projects we run across London, around 80% of clients arrange a temporary alternative, such as a family member’s house, a friend’s shower, or a short-term gym membership, for the days when water is fully isolated. The remaining clients manage with a second bathroom in the property.
Once demolition starts, the toilet, shower, and basin are disconnected and the water is isolated at the stopcock. If this is your only bathroom, expect to be without it for the full core build, typically 5 to 10 working days depending on the project type, not the full project length.
A good contractor will always plan the noisiest and most disruptive days early in the schedule, and keep the site clean and safe every evening so the rest of your home stays liveable. Ask your builder for a clear day by day plan before work begins so you know exactly when you will be without water, and for how long.

Frequently Asked Questions
Can I use the bathroom during renovation?
No, not once demolition begins. Water is isolated at the stopcock on day one, and the toilet, shower, and basin are disconnected until the new suite is fitted. If this is your only bathroom, plan an alternative for the core build days.
How long after tiling can I shower?
Wait at least 24 hours after grouting before light use, and a full 72 hours after the final silicone bead is applied before showering properly. Tile adhesive, grout, and sanitary silicone all need separate curing time, and rushing this is one of the most common causes of leaks and mould later on.
Is it faster to do the strip-out myself?
It saves at most a day, and often costs more in the long run. A skilled fitter can strip a standard bathroom in a day to a day and a half, and will spot issues like old lead pipework or rotten flooring while they go. DIY strip-outs frequently damage waste pipes or crack tiles that were meant to be reused, which adds delay rather than removing it.
Why do some quotes say 6 weeks and others say 2 weeks?
This usually means the two quotes cover different scopes. A 2 week quote is often a like-for-like refresh, while a 6 week quote may include a full layout change, a wet room conversion, or the lead time for bespoke materials. Always ask a contractor to separate the working-day build time from the material lead time so you are comparing like for like.
Do I need planning permission for a bathroom renovation in London?
In most cases, no. Replacing a suite, retiling, or moving fittings within the existing room does not usually require planning permission. You may need approval if you are adding a bathroom where one did not exist before, altering the external structure, or working on a listed building. Always check with your local London borough council if you are unsure.
What is the biggest cause of delay on a London bathroom renovation?
Material lead times, particularly for imported or bespoke tiles. The second most common cause is hidden pipework or structural issues in older London properties, which only become visible once the old suite has been removed.
