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.
Waterproofing and wet rooms in Sutton
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.
En-suites and clever layouts in period homes
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.
