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.
Whatever type of house you own in Sutton, we start by looking at how a new bathroom would fit it rather than offering a standard package. We cover KT4, SM1, SM2 and SM3 and neighbouring places such as Carshalton, Banstead and Ewell. One named person looks after you from survey to handover, and nothing is booked until you hold our figure in writing, fixed for the work described.

Building in Sutton
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 Sutton, 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 Sutton?
Planning law differs across the UK. For a home in Sutton, 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.
How does the job run?
We look at the job
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new bathroom.
Plan and prepare
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 work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Common 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 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.
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.
Do I need a new boiler for a new shower?
You do not always need a new boiler for a new shower, but your hot water system decides what kind of shower will work well. Combi boilers suit mixer showers directly from the mains. Tank-fed systems may need a pump for good pressure, and electric showers heat their own water. We check your boiler, cylinder and water pressure during the survey and recommend a shower to match.
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 Sutton 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.
