Waterproofing and wet rooms in Belgravia homes

Fitting a wet room or walk-in shower into a period Belgravia townhouse depends on getting the waterproofing right first. We tank the floor and walls properly before tiling, so water cannot reach the original timber floors and lath-and-plaster below. We form the falls, set the drainage and install proper ventilation to manage moisture in rooms that were never designed for modern showering.

Underfloor heating suits these often cool, high-ceilinged townhouses, adding comfort without wall-mounted radiators taking up limited space. We tile to a high standard and handle the plumbing and notifiable electrical work with building control sign-off. On listed properties we plan the installation to protect historic fabric and confirm whether listed building consent applies before altering original features.

En-suites and space-saving layouts in SW1

Belgravia townhouses often need extra bathrooms carved into existing bedrooms, landings or awkward corners, so we design en-suites and family bathrooms that make the most of tight or irregular spaces. We plan drainage runs carefully within the constraints of a multi-storey period house, working out how to connect new soil and waste pipes without disturbing the fabric more than necessary.

In smaller mews properties every centimetre counts, so we specify compact fittings and clever layouts that keep the room practical. From tanking and drainage to tiling, ventilation and underfloor heating, we deliver a bathroom that works reliably for years and suits the quality expected of a Belgravia home, all finished to a high standard by one team.

George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.

Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.

Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!

FAQ

Frequently Asked Questions about Bathroom Renovation Belgravia

How much does bathroom renovation cost in Belgravia?

The cost of bathroom renovation in Belgravia depends on the size of the property, the specification and the scope of work. GS Renovation provides free, detailed and itemised quotations for every Belgravia project. Call 07472 424 226 or email info@gsrenovationltd.co.uk for a no-obligation estimate. 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 long does bathroom renovation take in Belgravia?

A straightforward Belgravia project can be done in a couple of weeks, while a larger bathroom renovation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

Why choose GS Renovation for bathroom renovation in Belgravia?

With more than three decades of hands-on trade experience behind us, GS Renovation is a trusted choice for bathroom renovation in Belgravia. You get one accountable team, transparent pricing, fully insured tradespeople and genuine aftercare on every project.

Do I need building regulations for a bathroom in Belgravia?

Yes. Bathroom electrics in Belgravia are notifiable under Part P and must be certified, and any drainage, ventilation or structural changes must meet building regulations. We include certified electrical work and manage building control on every bathroom project.

Do you work on period, Georgian and listed homes in Belgravia?

Yes. A large share of Belgravia's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.

Can you fit an en-suite into my Belgravia townhouse without damaging period features?

Yes. We plan drainage and pipe runs to connect a new en-suite while disturbing original fabric as little as possible, and we tank the space fully to protect period floors below. Adding a bathroom does not need planning permission, though electrics are notifiable under building regulations. If your townhouse is listed, we confirm whether listed building consent applies before altering any historic feature.

Do you cover all of Belgravia?

Absolutely. Our team works right across Belgravia and the SW1 area and neighbouring parts of Central London. Get in touch on 07472 424 226 to check coverage for your address.
