A bathroom installation replaces your old suite with new sanitaryware, a bath or shower, tiling and fittings, including the plumbing, electrics, ventilation and waterproofing needed for a complete, watertight room.
We arrange a new bathroom for homeowners in Hanworth and the wider London. The job is planned, priced and managed by us and carried out by tradespeople engaged under our contract, so there is one agreement and one contact. On a typical home the work takes 1–2 weeks per bathroom, and guide pricing in London is £6,500–£15,500, VAT included.

Homes in London
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
None of this holds for every street in Hanworth, which is why we look at your actual house before pricing a new bathroom rather than assuming from its age alone.
Do you need permission in Hanworth?
Planning law differs across the UK. For a home in Hanworth, it is the England rules below that count, and we check them with the council ahead of any quote.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
We look at the job
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new bathroom, and photograph or measure anything the quote needs to reflect.
Written quote
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Booking the work
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
On site to finish
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.
How we work
Frequently asked questions
How much does a new bathroom cost?
A typical family bathroom costs £6,500–£15,500 supplied and fitted, including tiling, a new suite, shower, lighting and an extractor fan. Shower rooms and simple en-suites cost a little less, while wet rooms, standalone baths and large-format tiles cost more. Moving the toilet or replacing rotten floorboards adds to the total. We confirm a fixed price for the agreed specification after the survey.
Can you combine a new bathroom with other work?
Yes. Because we manage several trades under one contract, we can plan a new bathroom alongside other work on your Hanworth home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
How long does it take to fit a bathroom?
Fitting a typical bathroom takes one to two weeks on site. Strip-out and first-fix plumbing and electrics come first, followed by any plastering or boarding, waterproofing, tiling and then the suite, taps and fittings. Wet rooms and rooms with underfloor heating take longer because screeds and waterproofing need time to cure. We give you a day-by-day plan before work starts.
Can I move the toilet to a different position?
Moving a toilet is usually possible, but it is limited by the soil pipe, which needs a large-diameter pipe with a steady fall to the soil stack. Short moves along the same wall are often simple, while moving it across the room may mean lifting floors or boxing in pipework. A macerator pump is an option where gravity will not work. We check the stack position during the survey.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
