GS Renovation renovates bathrooms across Mitcham, making the most of the sometimes tight bathroom spaces in 1930s semis and interwar terraces in CR4. With over 30 years in the Merton area, we handle everything from waterproofing and tanking to tiling, underfloor heating and the drainage, so the finished room lasts.
Wet rooms and en-suites in Mitcham houses
Interwar Mitcham houses were rarely built with the bathrooms families want now, so we often reconfigure the original layout to create a proper walk-in shower, a wet room, or an en-suite carved out of a bedroom or a landing recess. Getting a wet room right starts below the tiles, with full tanking and waterproofing so there is no risk of water tracking into the floor structure of an older house. That groundwork matters far more than the finish that sits on top.
Drainage and ventilation are planned from the start, because a good-looking bathroom that steams up or drains slowly is a false economy. We set falls correctly, run new soil and waste where the original runs are undersized, and fit extraction that actually clears the moisture. In the smaller bathrooms typical of CR4 semis, careful layout and space-saving fittings free up room without making the space feel cramped.
Tiling, heating and finish across CR4
Once the room is watertight, the finish is where a Mitcham bathroom earns its keep. We tile floors and walls to a standard that suits a period home, set out so the lines run true against the not-always-square walls of a 1930s house. Underfloor heating warms the floor and frees up wall space that a radiator would otherwise take, which is welcome in the compact bathrooms these interwar homes were built with.
We coordinate the plumbing, the electrics and the tiling so the trades follow in the right order and nothing is disturbed later. Bathroom electrics are notifiable under building regulations, which we handle as part of the work, and there is no planning permission needed for an internal bathroom. From a family bathroom refit to a discreet en-suite, the result is built to cope with daily use for years.
