Compare complete bathroom renovation quotes in Westminster
Repeated leaks and failing finishes can make it difficult to tell which parts of a bathroom are still sound. Tell us about the bathroom in Westminster and what has prompted the renovation. A free enquiry through London Bathroom Fitters can help you obtain up to four quotations from independent firms covering your postcode, depending on suitable contractors being available.
For a home in Westminster, London, include the neighbourhood and postcode. Describe the floor level, delivery route and any shared services before a survey is booked. You decide whether any quotation suits your plans.
Opening up the room before rebuilding it
Everything comes out, including tiles, flooring, boxing and usually the ceiling, so that the pipes, wastes, cables and floor structure can be renewed before the new suite goes in.
Because the walls and floor are open, this is also the stage to reposition a radiator, add a towel rail circuit, move a light or fit a proper ducted extractor. Changes made after tiling are far harder and dearer.
Is a complete renovation right for your bathroom?
Mention any of these to the fitters who quote.
- Hollow or cracked tiles, or tiles laid over an older layer.
- A stain or patch on the ceiling below the bathroom.
- Springy boards around the WC or bath.
- Old lead or iron pipe visible under the bath.
- No working extractor, or one that vents into the loft.
Getting your Westminster enquiry right
Measure the floor and note the ceiling height, window position and door swing. Say whether the property is a house or a flat, and roughly when the bathroom was last done. Mention your boiler or cylinder, because the hot water system affects which shower you can have.
Include a photo of the ceiling below if there has been a leak. Say where a skip could go, or whether waste will need bagging and collecting.
How a renovation usually runs
- Survey the room, agree the layout and choose the suite, tiles and valves.
- Cover floors and stairs, then remove the old suite, tiles, boards and ceiling.
- Repair the floor, then run new pipework, wastes and cabling.
- Prepare the surfaces, tank the wet areas and lay the tiles or panels.
- Fit the suite, lights and extractor, test everything and hand over the certificates.
Most renovations take 8–14 working days once work begins. Drying times, made-to-measure glass and access arrangements can stretch the overall timetable.
Checks before a renovated room is tiled
Tiles are a finish, not a substitute for a waterproofing system. Ask which boarding, membrane and corner details the fitter will use, and how the tray junction and pipe penetrations will be sealed. Compatible components and the required curing periods matter as much as the tile choice.
A full strip-out does not automatically mean replacing every joist. Damaged boards, rotten timber or weakened joists need a priced repair plan. Any structural alteration must be designed appropriately; new pipes should not be routed by cutting away whatever timber is in the way.
Ask the fitter to document hidden services at the preparation stage. The handover should include leak and flow checks, fan testing, relevant electrical paperwork and advice on when sealant and grout are ready for use.
Check these points in the written scope before work starts.
- Agree how isolation valves and concealed shower controls remain accessible.
- Include repair of damaged substrates, waterproof corners and the tray-to-wall junction in the scope.
- Confirm that the extractor duct reaches outside and that the room has an adequate air supply.
What drives the price in Westminster
Use a starting budget range of £8,000–£16,000 for labour, a mid-range suite and tiling. Access restrictions and concealed repairs can take a price outside the guide range. Room size, the amount of tiling, the specification of the fittings and how difficult the room is to reach all move the figure.
Damaged joists, a lead supply pipe, a ceiling that needs replacing or asbestos testing are usually priced once the room is open. Check whether the quote lists provisional sums for hidden repairs.
Rules that can apply to a renovation
Renovating an existing bathroom rarely needs planning permission, but listed buildings can need listed building consent for internal changes. Electrical work in a bathroom can be notifiable under Approved Document P, so ask who will certify it. A new extractor should meet the rates in Approved Document F.
If you own a flat, check your lease before booking the work. Many London leases control changes to floors, drainage and walls.
For a skip licence, parking suspension or listed building questions, contact Westminster City Council. Ask whether the licence fee is included.

London Bathroom Fitters passes enquiries to independent bathroom businesses and is not a contractor itself. We do not survey, supply or fit bathrooms, and the fitters who reply are not our staff. Firms are asked for proof of insurance and for references when they sign up, and any agreement for the work is made between you and the fitter you pick.
Questions about renovations in Westminster
Use these to prepare for the survey visit.
What is the guide price for a complete bathroom renovation in Westminster?
Our indicative London range is £8,000–£16,000 for labour, a mid-range suite and tiling. It is not a fixed quote. Hidden repairs found after the strip-out are usually priced separately.
How long will I be without a bathroom in Westminster?
The work usually takes 8–14 working days, and the room is out of use for most of it. Ask whether the fitter can reconnect the WC at the end of each day during the early stages.
Will the old pipework be replaced?
In a complete renovation the pipework inside the room is normally renewed. Supply pipes elsewhere in the house, such as an old lead main, are a separate item and should be listed in the quote if included.
Do I need to move out during a renovation in Westminster?
Most people stay at home, but the bathroom is unusable for much of the job and there is dust and noise during the strip-out. If it is your only bathroom, plan where you will shower for around two weeks.
Will every joist be replaced in a renovation in Westminster?
No. Sound joists can remain after inspection. Rotten or weakened timber may need repair or replacement, and structural changes need an appropriate design. Ask how any extra work will be agreed and priced.
Is new grout enough to waterproof the shower?
No. Grout and silicone are parts of the finished surface. The shower area needs a suitable waterproofing arrangement beneath the finish, with sealed junctions and penetrations appropriate to the chosen system.
