Luxury bathroom and wet-room refurbishment in Mayfair. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates bathrooms, en-suites and wet rooms across Mayfair, fitting them into the Georgian and Regency townhouses of W1. With over 30 years of experience in Westminster, we handle the waterproofing, drainage, tiling and finishes, making the most of the often awkward spaces found in period homes near Hyde Park and the West End.

Fitting a new bathroom or en-suite into a Mayfair townhouse means working with solid walls, existing drainage runs and rooms that were never designed for modern plumbing. We tank and waterproof thoroughly before tiling, form falls correctly for wet rooms and walk-in showers, and add proper ventilation to protect the historic fabric from damp. Underfloor heating is often the neatest way to warm these tall, cool rooms.
Space in period W1 homes is frequently tight, so we design layouts that use every inch, tucking en-suites into former dressing rooms or under staircases and choosing fittings that suit the proportions. Drainage in a multi-storey townhouse needs careful planning to run new soil pipes discreetly through the structure. Because bathroom electrics are notifiable under building regulations, we handle the certification as part of the works.
A bathroom in a Mayfair townhouse can be traditional or contemporary, but it should sit comfortably within a period home. We fit everything from classic roll-top schemes with heritage-style brassware to sleek walk-in showers finished in large-format stone, tiling to a high standard throughout. Quality tanking beneath the surface is what keeps a beautiful bathroom watertight for years, and we never cut corners on it.
Many of Mayfair's finest homes are listed or in a Westminster conservation area, so we work sympathetically with original features and use appropriate materials where consent applies. Internal bathroom work does not need planning permission, though it is governed by building regulations. From concealed cisterns to underfloor heating and considered lighting, we manage the plumbing, electrics, tiling and decoration as one coordinated job.
Bathrooms in Mayfair's period townhouses hinge on getting the waterproofing, drainage and ventilation right beneath a beautiful finish. GS Renovation handles the tanking, the pipework, the notifiable electrics and the tiling as one accountable job, making clever use of tight period spaces. With 30+ years across W1 and Westminster, we deliver en-suites and wet rooms that stay watertight and look the part.
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!
