Luxury bathroom and wet-room refurbishment in Belgravia. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Belgravia, working within the Georgian and Regency townhouses and mews properties of SW1. Fitting modern, watertight bathrooms into period homes takes real care, especially where a property is listed. With over 30 years of experience, we handle the waterproofing, drainage, tiling and finishes throughout.

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.
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.
Belgravia owners choose GS Renovation because fitting watertight, modern bathrooms into period and listed townhouses demands proper tanking, drainage and ventilation, not shortcuts. We protect original floors and fabric, sign off notifiable work with building control and finish to a high standard. With 30+ years across SW1, your bathroom is built to last in a demanding home.
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!
