Bathroom refurbishment London
Bathroom refurbishment and renovation in London, start to finish
A bathroom refurbishment brings more trades into one small room than any other job in the house: a plumber for the supply and waste pipes, an electrician for the lighting, extractor fan and towel rail, a plasterer, a tiler and a fitter for the suite. When those trades are booked separately, most delays come from one waiting for another. Plumbery runs the whole bathroom renovation with one team and one point of contact, from strip-out to the final clean.
Most of the bathrooms we refurbish in London are in Victorian and Edwardian terraces, mansion blocks and converted flats, where pipe runs are long, floors are rarely level and the soil stack decides where the toilet can go. We check all of that on the survey, before anything is priced, so the estimate reflects your actual room and not a standard package.
Luxury bathrooms London
Luxury bathroom refurbishment for London homes
Most of our London bathroom clients want the room done properly, once: a principal en-suite with a walk-in shower and double basins, a freestanding bath, natural stone or large-format porcelain, underfloor heating and lighting planned with the layout. We take on complete, design-led bathrooms rather than quick replacements, and keep one project lead as your contact from survey to handover.
We regularly work in period houses and mansion flats in Kensington and Chelsea, Westminster, Camden, Islington, Hampstead, Richmond and Wandsworth, where floors need checking under heavy baths, hot water has to keep up with rain showers, and managing agents ask for method statements before work starts.
What we refurbish
Bathroom projects our London fitters take on
Full bathroom renovation
Everything out back to the walls and floor, new pipework and electrics, waterproofing, tiling and a new suite.
Small bathroom and cloakroom
Compact rooms and downstairs WCs, with wall-hung toilets, short-projection basins and storage built into boxing.
En-suite installation
A new en-suite in a bedroom or loft, including the waste route, a pump where gravity drainage is not possible, and ventilation.
Wet room and walk-in shower
Level-access showers with a fully tanked floor and walls, a linear or centre drain and the correct fall to the outlet.
Bath to shower conversion
Taking out the bath and fitting a low-profile tray or wet-room floor with a glass screen and a thermostatic mixer.
Accessible bathroom
Level-access showers, grab rails, comfort-height toilets and lever taps for older or less mobile family members.
How it works
How a bathroom refurbishment runs, step by step
Free survey
We measure the room, check the soil stack, waste falls, water pressure, the electrics and the existing ventilation, and talk through the layout you want.
Written estimate
Labour at our published hourly rates, with materials listed separately, so you can see exactly what you are paying for before anything starts.
Strip-out and first fix
Old suite, tiles and boards removed and taken away, then new supply and waste pipes and cables run while the walls are open.
Waterproofing and boarding
Cement or waterproof boards, tanking in the shower and bath area, and plastering where walls are not being tiled.
Tiling
Floor and wall tiling, with movement joints and silicone at every change of plane so the finish stays watertight.
Second fix and fitting
Toilet, basin, bath or tray, screen, taps, towel rail, lights, mirror and extractor fan connected and tested.
Testing and handover
Pressure and leak checks, electrical testing and certificates, a full clean and a walk-through of everything before we leave.
Timescales
How long does a bathroom renovation take?
A full refurbishment of a typical London family bathroom usually takes around 7 to 12 working days on site. A small en-suite or cloakroom can be quicker; a wet room usually takes longer, because the tanking has to cure before tiling and the floor has to be built up to the correct fall.
Lead times for tiles and sanitaryware are separate from the time on site. We order materials after the estimate is agreed and start once everything has been delivered, so the bathroom is not left half-finished while a basin is on back order.
Included
What a full bathroom refurbishment includes
- Strip-out of the old bathroom and removal of all waste
- New hot, cold and waste pipework, with isolation valves on every outlet

- Waterproofing (tanking) around showers, baths and wet-room floors
- Wall and floor tiling, boxing-in and bath panels
- Fitting of the bath or shower tray, screen, toilet, basin, vanity unit and taps
- Plastering, making good and decorating where agreed
- Testing, electrical certificate and a full clean at handover
Cost
What affects the cost of a bathroom refurbishment in London
The biggest factors are the size of the room and the tiled area, whether the toilet, shower or bath moves (moving the toilet depends on the route to the soil stack), whether you want a wet room, and the sanitaryware and tiles you choose. Access matters in London too: parking, the congestion charge, a top-floor flat without a lift and building rules on working hours all add time.
To get a figure for your own bathroom, use the bathroom renovation cost calculator: choose a bath or shower, the toilet, basins, tiling and lighting, and see an estimate with labour, materials and VAT. Our hourly labour rates are on the pricing page.
Regulations
Building regulations and bathroom renovations in London flats
Bathroom electrics must follow the BS 7671 zones around the bath and shower, and work such as a new circuit or anything in the zones close to water is notifiable under Part P. Our electricians test the installation and issue the certificate. A bathroom also needs mechanical extraction under Part F, normally a fan of at least 15 litres a second, which we fit and duct as part of the refurbishment.
If you live in a leasehold flat, check your lease before booking: many London freeholders ask for a licence for alterations before a wet room or a change of layout, and some blocks only allow noisy work on weekdays. We can provide the method statement and insurance details your managing agent asks for. For structural or layout changes, see the GOV.UK guidance on building regulations approval.

Questions
Bathroom refurbishment in London: your questions
How long does a bathroom refurbishment take in London?
A full refurbishment of a typical family bathroom usually takes around 7 to 12 working days on site. Small en-suites can be quicker and wet rooms take longer because the tanking must cure before tiling. We give you a timetable with the estimate.
How much does a bathroom refurbishment cost in London?
It depends on the size of the room, the tiled area, whether anything moves and the products you choose. Use our bathroom renovation cost calculator for an estimate with labour, materials and VAT, then book a free survey for a written estimate.
Can you move the toilet, bath or shower?
Usually yes. The toilet position depends on a workable route to the soil stack with enough fall; where gravity drainage is not possible a macerator or pump can be used. We check this on the survey.
Do you supply the bathroom suite and tiles, or can I buy my own?
Either. We can source and deliver everything, or fit products you have bought. If you buy your own, we will give you a list of what is needed so nothing is missing on the day.
Do you install wet rooms and walk-in showers?
Yes. We build the floor to the correct fall, tank the floor and walls, fit the drain and tile, then test for leaks before handover.
Do I need building regulations approval for a new bathroom?
Replacing a bathroom like for like usually does not need approval, but new electrical circuits and work in the bathroom zones are notifiable under Part P, and a new bathroom needs extraction under Part F. Our electricians certify the electrical work.
Will I be without a toilet during the work?
In a home with one bathroom we plan the work so the toilet is out of action for as little time as possible, usually reconnecting it at the end of each working day where the layout allows.
Can you refurbish a bathroom in a leasehold flat?
Yes, we work in flats and mansion blocks across London. Check whether your lease needs a licence for alterations; we can send the insurance and method details your managing agent asks for.
Which areas of London do you cover?
Every London borough, and for bathroom, kitchen and extension projects, towns and cities within about 200 miles of London, including Birmingham, Bristol, Manchester, Leeds, Liverpool and Sheffield.
