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.
Getting a new bathroom right in Finchley starts with understanding the house you already have: its age, how it was built and what has been altered over the years.

Across London, guide prices run at £6,500–£15,500 including VAT, and homes in Golders Green, Muswell Hill and Cricklewood are covered too.

What are homes like around Finchley?
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.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
These patterns matter for a new bathroom: older walls, roofs and floors in Finchley can need different materials or extra preparation compared with newer homes.
Do you need permission in Finchley?
The notes below cover England, which is where Finchley sits. Rules change and every property is different, so we speak to the council before pricing your job.
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.
From survey to handover
Survey and measure
A free survey comes first. It gives us what we need to price a new bathroom properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Quote in writing
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Getting ready
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new bathroom are in place before the first day on site.
Finish and handover
Our trades complete a new bathroom while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

Common questions
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.
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.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Which postcodes in Finchley do you cover?
We cover N2, N3, N12 and NW4, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
What ventilation does a bathroom need?
A bathroom needs mechanical ventilation, usually an extractor fan, to remove steam and help prevent condensation and mould. Building regulations set minimum extraction rates for new or refitted bathrooms. A fan linked to the light with an overrun timer, or one with a humidity sensor, works well. Ducting should vent outside by the shortest practical route. We include a suitable fan in every bathroom quote.
