Luxury bathroom and wet-room refurbishment in Sutton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Sutton, working within the layouts of its 1930s semi-detached and interwar suburban houses. With over 30 years in SM1, SM2, SM3, SM5 and SM6, we deliver fully waterproofed bathrooms, wet rooms and en-suites, handling the drainage, tiling, heating and ventilation as a complete job.

A bathroom lives or dies on what sits behind the tiles, so every one we build in Sutton is properly tanked before a single tile goes up. For wet rooms and walk-in showers we form the falls, lay the waterproof membrane and seal every joint and upstand so water goes only where it should. In an interwar semi with timber floors, that groundwork is what stops leaks reaching the rooms below.
We plan drainage and ventilation as carefully as the finish. Moving a soil connection or adding an extractor is often needed when reconfiguring an old bathroom, and we route these correctly rather than compromising the layout. Underfloor heating, well-lit mirrors and quality tiling complete the room, giving these 1930s Sutton houses a warm, dry, modern bathroom that performs as well as it looks.
The interwar semis around Carshalton and Wallington often have a single family bathroom and a landing or box room that can become an en-suite. We plan these carefully, working out the drainage runs and the framing needed to add a shower room without eating into the bedrooms more than necessary, so the house gains a second bathroom that genuinely adds comfort and value.
Where the existing bathroom is tight, as it frequently is in a 1930s house, the layout does the heavy lifting. We choose sanitaryware to suit the dimensions, use a walk-in shower to free up floor space and build in recessed storage where the wall allows. Bathroom electrics fall under building regulations and are certified, and the plumbing, tiling and heating are all completed by our own team.
Sutton homeowners choose GS Renovation because we build bathrooms that are waterproof where it counts, not just smart on the surface. One team handles the tanking, drainage, ventilation, heating and tiling, with the electrics certified under building regulations. Over 30 years across the borough means we know how to fit a proper bathroom or en-suite into an interwar Sutton 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!
