A bathroom renovation is an exciting project, but one of the first questions homeowners understandably ask is:
Written by the team at The Bathroom Project — hands-on bathroom, plumbing and heating specialists serving Bromley, Orpington and across Kent.
“How long will we be without our bathroom?”
The honest answer is that every project is different. A straightforward replacement bathroom may be completed relatively quickly, while a complete renovation involving layout changes, extensive tiling or multiple trades will naturally take longer.
At The Bathroom Project, we believe it’s important to give customers a realistic idea of the work involved before a project begins.
Quick answer: How long does a bathroom renovation take?
As a general guide:
Small or straightforward bathroom: approximately 1–2 weeks
Average bathroom renovation: approximately 2–3 weeks
Large or more complex bathroom: approximately 3–5 weeks or longer
These timescales can vary depending on the scope of work, product availability, plumbing changes and the condition of the existing room.
A properly planned project is usually more important than simply trying to finish as quickly as possible.
What happens during a bathroom renovation?
Although every project is different, most complete bathroom renovations follow a similar sequence.
Stage 1: Planning and preparation
Typical time: Before installation begins
Before work starts, the bathroom design, layout, products and materials should ideally be agreed.
This stage can include:
Measuring the existing bathroom
Discussing layout options
Selecting bathroom products
Choosing tiles
Planning lighting
Identifying plumbing requirements
Ordering materials
Good planning helps reduce unnecessary delays once installation begins.
Stage 2: Removing the existing bathroom
Typical time: 1–2 days
The old bathroom is removed, including any existing sanitaryware, tiles and fittings that are being replaced.
Depending on the project, this may include:
Bath removal
Shower removal
Toilet and basin removal
Removing wall and floor tiles
Removing old flooring
Stripping back walls where necessary
At this point, the condition of the room underneath can also become clearer.
Stage 3: Plumbing and first-fix work
Typical time: 1–3 days
This is where any required plumbing alterations are carried out.
For example:
Moving pipework
Changing the position of sanitaryware
Installing new shower valves
Altering waste pipes
Preparing plumbing for new fixtures
More significant layout changes can naturally increase the time required.
This is one reason experience in plumbing is important when carrying out a complete bathroom renovation.
Stage 4: Preparing the room
Before the finished bathroom starts to take shape, the room often requires preparation.
This may include:
Repairing walls
Levelling floors
Boarding walls
Waterproofing wet areas
Preparing shower spaces
Creating niches or recesses
This work isn’t always immediately visible in the finished bathroom, but it’s critical to creating a durable installation.
Stage 5: Tiling
Typical time: 2–5 days
Tiling can be one of the most time-consuming parts of a bathroom renovation.
The timescale depends on:
How much of the room is tiled
Tile size
Tile patterns
Cuts and detailing
Feature walls
Shower areas
Recessed niches
A large-format tiled bathroom may have fewer tiles to install but can still require careful preparation and handling.
More detailed designs, patterns and feature walls can increase the installation time.
Stage 6: Installing the bathroom
Typical time: 2–4 days
Once the room is ready, the main bathroom products can be installed.
Bath
Shower
Shower screen
Toilet
Vanity unit
Basin
Taps and brassware
Mirrors
Accessories
This is the stage where the bathroom starts to look like a finished space.
Stage 7: Finishing touches
The final stage includes the details that bring everything together.
This may involve:
Silicone sealing
Grouting
Installing accessories
Final plumbing connections
Finishing trim
Final checks
A final inspection should ensure everything is functioning properly and the room is ready for use.

What can make a bathroom renovation take longer?
Some factors are outside anybody’s control.
Common causes of longer timescales include:
Hidden problems
Once the old bathroom has been removed, issues can sometimes be discovered, such as:
Damaged floors
Water damage
Uneven walls
Old pipework
Structural issues
These problems should be dealt with properly rather than covered over.
Layout changes
Moving a toilet, shower or basin can involve additional plumbing and building work.
Complex tiling
Large feature walls, patterns, natural stone and intricate cuts all require additional time.
Product availability
A project can be delayed if a key product arrives late or damaged.
Additional work
Occasionally, customers decide to make changes once work has started. Where possible, finalising the design before installation helps keep the project moving.
Can a bathroom be renovated in one week?
Some straightforward bathroom replacements can potentially be completed in around a week.
However, a full renovation involving:
Complete strip-out
Plumbing changes
Waterproofing
Extensive tiling
New flooring
Multiple bathroom products
will usually require longer.
A quicker installation isn’t automatically a better installation.
The important thing is allowing sufficient time for each stage of the work to be completed properly.
How can homeowners prepare for a bathroom renovation?
There are several things that can make the process easier.
Choose products before work starts
Where possible, finalise:
Bathroom suite
Taps
Tiles
Furniture
Lighting
before installation begins.
Clear the room
Remove personal belongings and anything that may get in the way.
Plan for temporary disruption
If the bathroom is your only bathroom, consider how you’ll manage while work is taking place.
Discuss access
Make sure the installation team knows about:
Parking
Access to the property
Pets
Working hours
Any special requirements
Frequently Asked Questions
How long does it take to completely renovate a bathroom?
A complete bathroom renovation typically takes around 2–3 weeks, although smaller straightforward projects may take less time and larger or more complex renovations can take longer.
How long will I be without a shower during a bathroom renovation?
This depends on the project and the existing facilities in the property. During a complete renovation, the shower may be unavailable for part of the installation process. This should be discussed before work begins so you can plan accordingly.
What takes the longest during a bathroom renovation?
Tiling, waterproofing, room preparation and significant plumbing changes are often among the more time-consuming stages.
Can I stay in my house during a bathroom renovation?
In most cases, yes. However, there will be noise, dust and disruption while work is carried out.
Is it better to renovate a bathroom quickly?
The goal should be an efficient but properly managed installation. Rushing important stages such as preparation, waterproofing or finishing can create problems later.
