Wet rooms and tanking in Southall bathrooms

A bathroom lives or dies on what sits behind the tiles, so every refit we do in Southall starts with proper waterproofing. For wet rooms and walk-in showers we tank the floor and walls before tiling, form the falls correctly to the drain, and seal every junction so water goes where it should and nowhere else. In the interwar semis around UB1 this protects the timber floors and the ceilings below, which is exactly where hidden leaks cause the most damage.

Ventilation and drainage are planned at the same time. We upgrade extraction to clear moisture properly, reroute or renew waste pipes where the old runs are tired, and make sure everything meets building regulations. New electrical work in a bathroom is notifiable, and we handle that, with no planning permission needed for an internal bathroom. The result is a room that stays dry, warm and mould-free through the winters, not just one that looks good on day one.

Space-saving layouts for interwar Southall homes

Bathrooms in 1930s Southall semis are often modest, sometimes with an original layout that wastes space. We replan them to work harder, choosing space-saving sanitaryware, wall-hung units and walk-in enclosures that free up floor area, and squeezing en-suites out of a corner of a bedroom or a landing where the plumbing allows. Underfloor heating clears the wall of a radiator and warms the tiles underfoot, which suits these solid-floor and suspended-floor interwar homes well.

Tiling and finishing are where the room comes together, so we set out tiles to suit the proportions, keep grout lines clean and detail the shower and niche properly. For families in UB1 who want a second bathroom, an en-suite or a downstairs WC, we find the layout that fits the house and route the drainage sensibly. One team handles the tanking, the first fix, the tiling and the fit-out, so the bathroom is delivered right through in a single, tidy programme.

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.

GS Renovation's team brings over 30 years of hands-on experience to bathroom renovation and wider building work across Southall and the surrounding area. We offer free quotes, a dedicated project manager, full insurance, building control compliance where required, and comprehensive aftercare.

Do I need building regulations for a bathroom in Southall?

Yes. Bathroom electrics in Southall are notifiable under Part P and must be certified, and any drainage, ventilation or structural changes must meet building regulations. We include certified electrical work and manage building control on every bathroom project.

Do you work on 1930s and interwar homes in Southall?

Yes. A large share of Southall's homes are 1930s and interwar properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.

Can you fit a wet room or walk-in shower in my Southall interwar house?

Yes. The key is proper tanking, so we waterproof the floor and walls, form correct falls to the drain and seal every junction before tiling, which protects the timber floors common in 1930s Southall semis. We also upgrade ventilation and drainage and add underfloor heating if you want it. New bathroom electrics are notifiable under building regulations, which we handle. No planning permission is needed for an internal bathroom.
