GS Renovation renovates bathrooms across New Malden, where the interwar semis of KT3 often have a single family bathroom and awkward, dated layouts to work around. With 30+ years in Kingston upon Thames, we deliver fully waterproofed bathrooms, wet rooms and en-suites, handling the drainage, tiling and finish from start to finish.
Waterproofing and wet rooms in New Malden
A bathroom that lasts starts with what you cannot see. In New Malden's interwar homes we tank and waterproof the walls and floor properly before a single tile goes on, which matters on the timber upper floors typical of these 1930s semis. For walk-in showers and wet rooms we form the falls carefully so water drains where it should, then tile onto a fully sealed substrate.
Good drainage and ventilation finish the job. We upgrade waste runs where the original pipework is undersized and fit effective extraction to manage the moisture that older KT3 bathrooms struggle with. The result is a warm, dry room that protects the interwar structure around it rather than slowly damaging the joists and plaster over the years.
En-suites and space-saving layouts in KT3
The bedrooms in a New Malden semi often have room to carve out a compact en-suite, and we plan these tight spaces around the existing soil stack and joists so the drainage runs sensibly. Wall-hung basins and toilets, walk-in showers and clever storage make the most of the footprint, turning an unused corner of a 1930s bedroom into a genuinely usable second bathroom.
Underfloor heating suits these renovations well, freeing wall space and warming the tiled floors that can feel cold in an interwar house. The wiring for a heated floor and the bathroom electrics are notifiable under the Building Regulations, so we certify them correctly. From layout to the final grout line, one KT3 team delivers a bathroom that works hard in a small space.
