Luxury bathroom and wet-room refurbishment in Forest Hill. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms, en-suites and wet rooms across Forest Hill, working within the tight footprints of SE23's Victorian and Edwardian terraces. With over 30 years in the area, we handle the waterproofing, drainage, tiling, heating and ventilation in-house, so your new bathroom is built to last in a period home near the leafy hills of Forest Hill.

Many Forest Hill bathrooms sit in the rear closet wing or a converted box room, where space is tight and the plumbing is often original. We strip back to the joists, upgrade the drainage and ventilation, and tank the whole area properly before a single tile goes on. Tanking and waterproofing matter most in a walk-in shower or wet room, where water has to be contained fully, especially above a habitable room in a terrace.
Creating an en-suite in an SE23 terrace usually means borrowing space from a bedroom or the landing, so we plan the layout to keep it feeling generous despite the small footprint. Concealed cisterns, wall-hung basins, walk-in showers and good extraction all help. Where a soil pipe needs rerouting or a macerator is the only realistic option, we advise honestly on what the existing drainage and structure will allow.
Period terraces rarely offer a large family bathroom, so clever planning does the heavy lifting. We square up out-of-true walls, use the depth of a chimney breast or alcove for storage, and choose sanitaryware scaled to the room. Underfloor heating frees the walls of radiators and warms tiled floors that would otherwise feel cold, a real benefit in the solid-walled Victorian homes typical of Forest Hill and the streets towards Telegraph Hill.
The details are what make a small bathroom last. We use decoupling membranes over timber floors to stop movement cracking the tiles, seal every junction, and specify extraction that clears moisture before it causes damp in an older house. Tiling, underfloor heating, lighting and the final fit of taps and screens are all done by our own tradespeople, and any new electrics are certified under building regulations.
Forest Hill homeowners choose GS Renovation because we get the hidden work right, the tanking, drainage and ventilation that decide whether a bathroom survives in a period terrace. One team manages the waterproofing, tiling, heating and electrics, so there is no finger-pointing between trades. More than 30 years across SE23 and neighbouring Lewisham inform every detail.
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!

We reinforce and level the floor where needed, install a decoupling and tanking system, and set the falls so water drains correctly to the waste.
