Luxury bathroom and wet-room refurbishment in Charlton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Charlton, fitting them into the closet wings and tight upper floors of the area's bay-fronted Victorian and Edwardian terraces. With more than 30 years in SE7 and the Royal Borough of Greenwich, we handle the waterproofing, drainage, tiling and finishes so a period bathroom performs like a modern one.

A lasting bathroom starts with getting the waterproofing right, especially in a Charlton terrace with suspended timber floors and solid walls. We tank the wet areas properly before tiling, form falls for a walk-in shower or full wet room, and make sure the drainage and extraction are sized to cope. Skipping the tanking is how leaks and damp start, so we never treat it as optional in SE7 period homes.
Ventilation matters just as much in these older houses, where trapped moisture leads to mould and rot. We fit proper extraction, upgrade the drainage where the original pipework is tired, and can add underfloor heating to keep tiled floors warm and the room drying quickly. The result is a bathroom that looks the part and stays sound in a period Charlton house for years to come.
Charlton's Victorian and Edwardian terraces rarely have space to spare upstairs, so a well-planned layout makes all the difference. We often carve an en-suite out of a bedroom corner or rework the awkward footprint of a rear closet wing, choosing compact fittings, walk-in showers and clever storage to get a usable bathroom into a tight SE7 space without it feeling cramped.
Every layout is planned around the existing structure, the run of the soil pipe and the window positions typical of these terraces. We handle the tiling, the underfloor heating, the sanitaryware and the lighting in-house, and any electrical work in the bathroom is carried out and certified as notifiable under building regulations, so the finished room is safe, warm and built to make the most of the space.
Charlton homeowners choose GS Renovation because we get the parts you cannot see right, the tanking, drainage and ventilation, as well as the tiling and finishes. We plan clever layouts for the tight closet wings and upper floors of SE7 terraces, certify the electrics to building regs, and back every bathroom with 30+ years in the Royal Borough of Greenwich.
I am very happy to recommend George after he completed the work on my 2 bathrooms. He worked very hard to make sure everything was completed and even came on a Sunday evening to finish the work...which shows how committed he is to…
Built a new extension at rear of property. Laid foundations, drainage, raised floor, new roof and completed all fixtures and interior decoration. Also in 2015 completed patio in garden, steps around rear extension. He did a fantastic job…
George was very friendly and helpful from start to finish. He worked really hard to ensure our kitchen was installed to a high standard and was accommodating to the changes we wanted along the way. We're really happy with the end result…
FAQ
We do not price bathroom renovation over the phone for Charlton homes. A figure given blind is a figure that changes, so we survey the SE7 address, then quote in writing for Charlton. 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.
How long bathroom renovation takes depends on how much comes out before anything goes back. We survey the SE7 property and give a Charlton programme GS Renovation can actually hold to.
Aftercare is not a brochure line. If something needs attention once bathroom renovation at the SE7 property is finished, you call the same number and reach the same people who did the Charlton work.
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 Charlton's older solid-wall properties, so we size extraction properly at the SE7 address rather than fitting the smallest unit that complies.
We work on them constantly. bathroom renovation at a SE7 address needs the structure confirmed by an engineer before design, and GS Renovation coordinates that as standard across Charlton.
Usually yes. Charlton's Victorian and Edwardian terraces are tight upstairs, but we regularly carve en-suites out of a bedroom corner or rework a rear closet wing using compact fittings, walk-in showers and smart storage. We plan the layout around the soil pipe and window positions, tank it properly, sort the ventilation and certify the electrics, so a small SE7 space works hard and stays sound.
Yes. We cover the whole of Charlton and the SE7 area for bathroom renovation, and the surrounding parts of Greenwich. Ring 07472 424 226 and we will confirm we work on your street before you go further.
