Luxury bathroom and wet-room refurbishment in Bromley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms across Bromley, from family bathrooms in interwar BR1 semis to compact en-suites carved out of period homes in Chislehurst and Beckenham. With over 30 years in the borough, we handle the waterproofing, drainage, tiling, heating and ventilation as one job, so your new bathroom is built to last and properly protected against leaks.

A walk-in shower or full wet room is a popular upgrade in Bromley's interwar houses, but it only works when the waterproofing is done properly. We tank the walls and floor before a single tile goes on, forming falls to the drainage so water runs away cleanly rather than pooling. Skipping this step is the usual cause of the damp and staining we are so often called in to put right in older BR-postcode homes.
In a 1930s semi in BR5 or BR6 the original bathroom is often small, so we plan the layout carefully to fit a generous shower, the sanitaryware and storage without it feeling cramped. We upgrade the drainage and extraction at the same time, because a well-ventilated bathroom stays free of condensation and mould, and we finish with tiling and heating designed to work together.
Interwar Bromley houses rarely came with en-suites, so we create them from the corner of a bedroom or an oversized landing, adding a bathroom near where the family sleeps without losing a whole room. We run the new drainage back to the existing soil stack, which needs planning around the layout of a 1930s semi, and we soundproof and ventilate the space so it works well within the house.
Underfloor heating suits these projects, freeing wall space in a tight en-suite and warming tiled floors that would otherwise feel cold. In period homes near Beckenham Place Park or Chislehurst Common we design space-saving layouts that use every inch, wall-hung basins, recessed shelving and slim shower enclosures, so a small footprint in BR3 or BR7 still delivers a proper, comfortable bathroom.
Bromley homeowners choose GS Renovation because we get the hidden work right, the tanking, the falls, the drainage and the ventilation, before any tiling begins. One team handles the plumbing, electrics, heating and finish, so there is no gap for leaks to appear later. With 30+ years across BR1 to BR7 and SE20, we build bathrooms that stay watertight.
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!
