Luxury bathroom and wet-room refurbishment in Catford. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Catford, working within the compact spaces typical of SE6 Victorian and Edwardian terraces. With over 30 years in South East London, we handle the waterproofing, drainage, tiling, heating and fit-out, creating watertight, well-ventilated bathrooms and wet rooms that make the most of the room available.

A bathroom lives or dies on what happens behind the tiles, which is why we tank and waterproof properly before anything is finished. In Catford terraces the bathroom often sits in the rear closet wing or over a cold external wall, so we apply a full tanking system to the shower area and floor, then lay tiles onto a stable, waterproof substrate. For walk-in showers and wet rooms we form the falls carefully so water runs to the drain and never sits.
Drainage and ventilation matter just as much in these older SE6 homes. We connect into the existing soil stack correctly, upgrade extraction to clear moisture and protect against the damp and mould that plague period bathrooms, and insulate where pipework runs against solid external walls. Get the fabric right and the finish lasts, rather than grout failing and tiles lifting a couple of winters later.
Space is the constant challenge in Catford's terraced houses, where bathrooms are often small and squeezed into the closet wing. We plan layouts that use the room properly, choosing wall-hung basins and toilets, compact walk-in showers and clever storage to make a tight footprint feel generous. Underfloor heating is a favourite here because it frees up wall space that a radiator would otherwise take.
Adding an en-suite is a common request as SE6 families reconfigure the upper floors, often carving one from a large bedroom or the landing. We handle the new drainage runs, the waterproofing, the ventilation and the tiling, and make sure the electrics are done to building regulations. Whether it is a main family bathroom or a compact en-suite, the aim is a practical, watertight room that suits a period Catford home.
Catford owners choose GS Renovation because we build bathrooms from the substrate up, tanking and waterproofing properly before a single tile goes on. We know how SE6 terraces are laid out, we solve the tight closet-wing spaces, and we handle drainage, ventilation and building-regulations electrics in house. Over 30 years locally means a bathroom that stays watertight, not one that fails after a couple of winters.

FAQ
You get a variation, in writing, before anything else happens. The commonest cause on a bathroom renovation job is a homeowner upgrading a finish once the SE6 space is open, which is entirely reasonable and easy to price. GS Renovation also re-checks the programme so a Catford project does not quietly slip. The Lewisham Council inspections are rebooked where needed. Ring 07472 424 226 to hear how that runs on an SE6 project in Lewisham. 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.
We will not open your house and disappear. Bathroom renovation at an SE6 property is scheduled so that the Catford job runs continuously through to making good and sign-off. GS Renovation keeps one team accountable rather than passing the Lewisham site between subcontractors. If a genuine emergency pulls anyone away you are told immediately, not afterwards. The Catford programme and the Lewisham Council inspection dates are reissued whenever anything at the SE6 property changes.
You get the scope in writing before anyone starts. The bathroom renovation quotation for your Catford home lists structure, trades, approvals and making good, and the programme names the weeks and the Lewisham Council inspection points at SE6. GS Renovation appoints and coordinates the structural engineer where the design needs one. Aftercare is a phone call to the same number, not a form. Ask on 07472 424 226 about Lewisham aftercare. The five year guarantee on installations applies in Lewisham too.
Part F sets the requirement, and in practice that means mechanical extraction to outside, never into a loft void. Condensation is a persistent problem in Catford's older solid-wall properties, so we size extraction properly at the SE6 address rather than fitting the smallest unit that complies.
Carefully, and in a defined order. We survey the SE6 property, confirm what the structure is doing, appoint an engineer where bathroom renovation requires a design, then prop, remove and support in sequence. GS Renovation agrees with the Catford homeowner beforehand which original features are being protected. Lewisham Council inspects before anything is concealed. GS Renovation will set out the whole bathroom renovation sequence planned for your SE6 home in Catford before anything at all starts.
It comes down to waterproofing and ventilation. In SE6 terraces we fully tank the shower and floor before tiling, insulate pipework running against cold external walls, and fit proper extraction to clear moisture. Getting the drainage connected correctly and the fabric right behind the tiles is what keeps damp and mould out of these period bathrooms for the long term, not just the visible finish.
There is no part of Catford we would exclude. Bathroom renovation is carried out throughout the area and the SE6 area and across neighbouring Lewisham, on terraces, semis and flats alike. GS Renovation knows how bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns are built, which is what makes an SE6 quotation accurate. Email info@gsrenovationltd.co.uk and we will book a free survey. Building control goes through Lewisham Council in the usual way. Small jobs and whole-house programmes are both quoted on the same basis.
