Bathroom Renovation London

Luxury bathroom and wet-room refurbishment in London. Trusted, professional, 30+ years' hands-on experience.

GS Renovation fits bathrooms, en-suites and wet rooms across London, working in the Victorian and Edwardian terraces that line streets from Greenwich to Chelsea. With more than 30 years in the capital, we handle the waterproofing, drainage, tiling and heating, making the most of the tight, awkward spaces these period homes so often provide.

Wet rooms and walk-in showers in London

A wet room or walk-in shower makes a small London bathroom feel bigger and far easier to use, but it only works if the waterproofing is right. We tank the floor and walls with a proper membrane system before a single tile goes down, form the falls so water runs to the drain, and set the waste into the joists of a suspended timber floor, which is what most London terraces have upstairs. Skip this and leaks find their way to the ceiling below.

Ventilation and drainage are the parts people forget until they go wrong. A London bathroom needs a proper extractor to clear the moisture that would otherwise rot timbers and blacken grout, and the new waste has to tie into the existing soil stack, often a Victorian cast-iron run at the back of the house. We plan both from the start, add underfloor heating to warm the tiles and dry the room quickly, and finish with tiling laid true and grouted to last.

En-suites and space-saving layouts in London

Space is the constant challenge in a London terrace, so we are used to carving a workable bathroom or en-suite out of very little. A boxroom above the stairs, the end of a landing, or a corner of a large bedroom can all become a neat shower room with the right layout. We use wall-hung sanitaryware, slim concealed cisterns and carefully chosen door swings to claw back every inch, and we plan the pipework so the room feels considered rather than squeezed in.

Period homes reward a bit of sympathy in the detailing. In a Victorian or Edwardian house we can pair traditional fittings, metro tiles and panelled bath surrounds with modern showers and heated towel rails, so the room suits the age of the property without feeling dated. Adding an en-suite to a main bedroom is popular across Islington, Wandsworth and Hackney, and where a new soil connection is needed we work out the run early, because in these houses the drainage dictates what is possible.

FAQ

Frequently Asked Questions about Bathroom Renovation London

Do you charge for a survey before quoting bathroom renovation in London?

There is no charge, and no pressure afterwards. GS Renovation surveys the London property, checks what bathroom renovation would actually require there, and issues an itemised figure for your London home. Quotes are free and no-obligation, which is the only fair way to price work of this kind. Call 07472 424 226 or email info@gsrenovationltd.co.uk to arrange a visit. Nothing at all is owed for the London survey or for the written London quotation. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

How many trades are on site during bathroom renovation in London?

It varies by stage, and they are coordinated rather than overlapping. The structural phase of bathroom renovation at a London property is a small team, after which electricians, plumbers, plasterers and decorators follow in sequence through your London home. GS Renovation manages them in-house so nobody waits on anybody. One named project manager runs the London site throughout. Ring 07472 424 226 and GS Renovation will name the trades due at a London property in London.

How do you handle problems during bathroom renovation in London?

Straight away and in writing, which is the only approach that survives a dispute. If the structure at your London address is not what the survey suggested, GS Renovation stops, brings the engineer back where bathroom renovation requires it, and re-prices honestly. The London programme is reissued. Weekly updates mean a London client never hears bad news late. Ring 07472 424 226 and we will explain the process. Weekly London updates on the London job keep surprises out of it.

Does a new bathroom in London need planning permission?

Not for internal work. Converting a bedroom to a bathroom in a London house is an internal alteration, so planning is not engaged, though building regulations are. External changes such as a new soil vent pipe on a London property may need permission in a conservation area.

How does London's Victorian and Edwardian terraced housing affect a bathroom renovation project?

Mostly by removing the guesswork a modern house allows. GS Renovation cannot assume how a Victorian and Edwardian terraced London property is built, so bathroom renovation starts with confirming it and the quotation follows from there. That is slower at the start and far more reliable afterwards. Homeowners right across London and London get exactly the same approach. Ask on 07472 424 226 what bathroom renovation at a London property in London has to establish before any design work.

Can I fit a wet room upstairs in my London Victorian terrace?

Yes, and we do it regularly, but the key is the timber floor. Upstairs in a London terrace the bathroom usually sits on suspended joists, so we tank the whole area with a waterproof membrane, form the falls to the drain, and set the waste neatly between the joists. Done properly it will not leak to the room below. The electrics and any new circuits are notified under building regulations.

Do you take bathroom renovation enquiries from anywhere in London?

Anywhere in the area, and there is no minimum job size. Bathroom renovation enquiries reach GS Renovation from across London and London, and each gets a free survey at the London property and a written quotation afterwards. Building control is coordinated with local authorities across London where the work requires it. Email info@gsrenovationltd.co.uk to get started. Nothing is owed whether you proceed or not. Small jobs at a London address are just as welcome here.
