Luxury bathroom and wet-room refurbishment in Southgate. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms, en-suites and wet rooms across Southgate's 1930s semis and interwar houses, where the original bathroom is often small and awkwardly placed. Drawing on more than 30 years in N14, we handle the waterproofing, drainage, tiling and heating so your new bathroom is built to last, not just made to look good.

A bathroom fails from the inside out, so we start with proper tanking. Before a single tile goes on, we waterproof the walls and floor of the wet zones, which matters in a Southgate semi where the bathroom often sits above a habitable room. For walk-in showers and full wet rooms we form the falls, lay the tanking membrane and test it, so water reaches the drain and nowhere else.
Drainage and ventilation are the parts nobody sees but everybody notices when they go wrong. In these interwar houses the soil pipe and vent runs are often original, so we upgrade them to cope with a modern shower and extract moist air properly to prevent damp and mould. Underfloor heating, warmed towel rails and quality tiling then turn a cold 1930s bathroom into a genuinely comfortable room.
The bedrooms in an N14 interwar semi are usually generous enough to carve out an en-suite, particularly the main bedroom over the bay. We plan the layout carefully so the new drainage can reach the existing stack without ugly boxing, and choose space-saving fittings that give a usable shower, basin and WC without crowding the bedroom. Careful setting out is what makes a small en-suite feel considered rather than squeezed.
The family bathroom in these houses is often a tight, single space, so clever planning earns its keep. A walk-in shower in place of a bath, a wall-hung WC and basin, and a well-placed mirror can transform how big the room feels. All the electrical work, from the shower to the lighting and heating, is carried out and notified under the building regulations, so your Southgate bathroom is safe as well as smart.
Southgate homeowners choose GS Renovation because we build bathrooms that stay dry for the long term, starting with thorough tanking and sound drainage rather than rushing to the tiling. One team handles the plumbing, electrics, waterproofing and finish, all to the building regulations. Thirty years in N14's interwar homes means we understand where these bathrooms sit and how to make them work.
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!

In most cases, yes. The main bedroom in a Southgate interwar semi usually has room for a compact en-suite, and the key is routing the new drainage to the existing soil stack cleanly.
