Luxury bathroom and wet-room refurbishment in Kensington and Chelsea. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes bathrooms and en-suites across Kensington and Chelsea, fitting out the townhouses and mews homes of SW3, SW7, W8 and W11. With 30+ years in the Royal Borough, we handle full waterproofing, drainage, tiling and heating, designing wet rooms and space-saving layouts that work within the awkward proportions of Georgian and Regency period properties.

Bathrooms in the townhouses of Chelsea and Notting Hill are often carved out of former bedrooms or landing space, on upper floors with timber joists that must stay dry. We tank and waterproof the whole area before tiling, forming falls to the drain for walk-in showers and wet rooms so water goes where it should. Correct drainage and mechanical ventilation are designed in to protect the period structure below.
Underfloor heating, tiling and the finishing work follow once the waterproofing is proven. In the tall, narrow homes across SW3 and W8, running new soil and waste pipes takes planning, so we route them discreetly through cupboards and voids. Notifiable electrical work for the bathroom is certified under building regulations, and the whole installation is designed to cope with the demands of daily use in a busy household.
The period homes of Knightsbridge, South Kensington and Holland Park rarely offer generous bathroom space, so clever layout matters. We add en-suites to principal bedrooms and reconfigure tight family bathrooms, using wall-hung sanitaryware, walk-in showers and concealed cisterns to free up floor area. Every layout is planned around the existing joists, chimney breasts and window positions of the original room.
Waterproofing standards stay the same whatever the size: full tanking, proper drainage falls and adequate extraction to prevent damp in these solid-walled properties. Underfloor heating warms cold period floors, and considered tiling and lighting lift a small space. Bathroom renovation is internal work requiring building regulations rather than planning permission, though in listed homes we check whether altering the room affects anything requiring consent.
Kensington and Chelsea owners choose GS Renovation because a bathroom in a period townhouse depends on getting the waterproofing, drainage and ventilation right on timber upper floors. We tank properly, route services discreetly and finish to a high standard, adding en-suites and wet rooms that suit tight period layouts. Thirty years across SW7, W8 and W11 stands behind the work.
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!
