Luxury bathroom and wet-room refurbishment in Southall. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refits bathrooms across Southall, from family bathrooms to en-suites and walk-in wet rooms in 1930s semi-detached and interwar homes. With over 30 years of experience in the UB1 area, we get the waterproofing, drainage and ventilation right first, then fit tiling, heating and fixtures that last in these solid interwar houses.

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.
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.
Southall homeowners choose GS Renovation because we build bathrooms from the waterproofing up, not just the tiles down. We tank wet rooms properly, sort drainage and ventilation, handle notifiable electrics under building regulations, and plan space-saving layouts that suit modest interwar rooms. With 30+ years across West London, one team delivers a bathroom that stays dry and looks right for years.
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!
