Luxury bathroom and wet-room refurbishment in Clapham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Clapham, working within the tight footprints of SW4's Victorian and Edwardian terraces. With over 30 years in South London, we handle waterproofing, drainage, tiling and heating in-house, turning cramped or dated rooms near the Common into properly finished, hard-wearing spaces.

Bathrooms in older Clapham terraces are frequently squeezed into the rear closet wing or a boxed-in landing, where a hidden leak can quietly damage the period fabric below. We tank and waterproof properly before tiling, so wet rooms and walk-in showers stay watertight for the long term rather than failing a few years in and soaking the joists.
Getting the services right matters as much as the finish. We upgrade drainage to fall correctly, add proper ventilation to deal with condensation in these solid-wall rooms, and set out underfloor heating where the floor build-up allows. The tiling, sanitaryware and lighting then go in over a sound, well-drained base that will not give trouble later.
Space is the constant challenge in an SW4 bathroom. The closet-wing rooms and narrow landings of Clapham terraces rarely offer much floor area, so we plan the layout carefully, using wall-hung units, walk-in showers and considered storage to make a small room feel usable rather than cramped, without wasting an inch of the footprint you have.
En-suites are a popular addition when we reconfigure the upper floors of a Clapham house, carving one out of a bedroom or a redundant box room. Bathroom work does not need planning permission, though the electrics are notifiable under building regulations, so we certify the wiring and extract properly and leave you with paperwork that stands up when you sell.
Clapham homeowners choose GS Renovation because we get the parts you cannot see right, tanking, drainage and ventilation, before the tiling ever goes on. One team handles the plumbing, electrics, heating and finish, we make the most of tight SW4 layouts, and our 30+ years mean the bathroom lasts rather than leaks.

FAQ
Usually the structural work and the making good, in that order. Steel, propping and the engineer's design account for the largest share of a bathroom renovation job at an SW4 address, and reinstating a Victorian and Edwardian terraced interior afterwards accounts for more than most people expect. The Lambeth Council fee is small by comparison. GS Renovation shows all three separately on the Clapham quotation. Ring 07472 424 226 and we will explain the balance at an SW4 property. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Three things, in practice: inspections, materials and late changes. A bathroom renovation project in a Clapham home stalls when Lambeth Council cannot attend before work is concealed, when a specified item has a long lead time, or when the specification changes after the SW4 order is placed. GS Renovation manages the first two and warns you about the third. Nothing about a Lambeth delay is hidden. The Clapham programme names when each Lambeth decision is needed.
Enough to know where the problems hide in an SW4 property before quoting. Bathroom renovation in Victorian and Edwardian terraced housing throws up variation that a modern estate does not, and 30 years of hands-on experience is what turns that into an accurate Clapham figure rather than a cautious one. GS Renovation has been incorporated since 2023. The experience behind it is considerably older. Ask on 07472 424 226 about Lambeth projects. References near SW4 are given as addresses, not testimonials.
Usually yes, and it is one of the commonest upgrades we make in Clapham. The constraints are the soil stack route and the floor structure, both checked at survey, and the electrics need Part P certification through Lambeth Council.
Rarely, because we expect what the stock throws up. Bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns bring aged materials, uneven floors and occasional unauthorised previous work, none of which stops bathroom renovation at an SW4 address but all of which affect the programme. GS Renovation allows for them in the Clapham quotation. Lambeth Council inspects the structural work either way. GS Renovation will happily describe what bathroom renovation usually reveals once an SW4 property in Clapham is opened up properly on site.
Yes. The compact closet-wing bathrooms in SW4 terraces often suit a wet room well, as removing the tray frees up floor space. The key is full tanking and correct drainage falls so the whole floor stays watertight over solid-wall construction. We waterproof properly, add good ventilation, and certify the electrics under building regulations, so the room performs for years.
Yes, both. Bathroom renovation in an SW4 flat brings the lease and the freeholder's consent into it, which is the main practical difference from a Clapham house, and GS Renovation will explain what applies before any design work. Building control still goes through Lambeth Council. Ring 07472 424 226, describe the block, and we will tell you what is involved. The survey across Lambeth is free either way. The freeholder's licence to alter comes first at SW4.
