Luxury bathroom and wet-room refurbishment in Barnes. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Barnes, working within the tight, awkward spaces typical of SW13's bay-fronted Victorian and Edwardian terraces and period cottages. With more than 30 years in South West London, we handle the waterproofing, drainage, tiling, heating and finish in one go, turning dated or cramped bathrooms into rooms that work.

A wet room only lasts if the waterproofing is done properly, and in a Barnes terrace with timber suspended floors that matters even more. We tank the whole area with a bonded membrane behind the tiling, form the falls to the drain, and make sure the shower cannot find its way into the joists below. Walk-in showers suit the narrower bathrooms of an SW13 home, giving a clean, open feel without a bulky enclosure.
Getting waste and ventilation right is half the job in a period bathroom. We reroute drainage to fall correctly, upgrade extraction to clear moisture from a room with little natural airflow, and often add underfloor heating so tiled floors are warm underfoot and dry quickly. Tiling is set out to suit the proportions of the room, and everything is finished to a standard that copes with daily family use in a Barnes home.
Barnes terraces rarely offer generous bathrooms, so clever planning counts. We carve en-suites out of a corner of a bedroom or the space over the stairs, choose compact sanitaryware, and use wall-hung units and recessed niches to keep floor area free. Sliding doors, concealed cisterns and considered lighting all help a small SW13 bathroom feel bigger. The aim is a room that is practical for a busy household yet still feels calm.
A new bathroom inside the house does not need planning permission, and most Barnes projects run straight from design to install. We manage the lot, moving pipework and waste, adding the extraction, running the electrics and fitting underfloor heating, then tiling and finishing. New bathroom wiring is notifiable and certified under building regulations. Working in an occupied home, we protect the rest of the house and keep to a clear, agreed timetable.
Barnes homeowners choose GS Renovation for bathrooms because the parts you cannot see, the tanking, the falls and the ventilation, are done right, not just the tiles on top. We work confidently in the tight spaces of SW13 terraces, manage every trade in-house, and certify the electrics under building regulations. With 30+ years locally, your bathroom is built to stay watertight.

FAQ
Rates per square metre are how quotations go wrong. What decides a bathroom renovation figure for a Barnes home is the structure, the access at SW13 and the reinstatement afterwards, none of which appear in a market average. GS Renovation itemises so the total can be traced back to real work. Homeowners across Richmond upon Thames are welcome to a free survey first. Ring 07472 424 226 and GS Renovation will explain what your SW13 property actually needs. 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.
Structure first, then services, then finishes, with the Richmond Council inspections fixed between them. That sequence is what stops trades undoing each other on a bathroom renovation job at an SW13 address, and it is written into the programme GS Renovation issues with the quotation. Your Barnes project is updated against it weekly. Nothing is concealed anywhere in Richmond upon Thames before it has been inspected. Ask GS Renovation on 07472 424 226 for the written SW13 programme before you commit.
Happily. Previous Barnes clients are usually willing to talk about how a bathroom renovation project actually ran, including what went wrong and how GS Renovation dealt with it. We will point you at recent work near SW13 and in Twickenham. The 31 MyBuilder reviews behind our 4.9 rating are public and cover the same ground. Ring 07472 424 226 to arrange a Richmond upon Thames introduction. Nothing about a Richmond upon Thames reference is curated by us at SW13.
Not for internal work. Converting a bedroom to a bathroom in a Barnes house is an internal alteration, so planning is not engaged, though building regulations are. External changes such as a new soil vent pipe on an SW13 property may need permission in a conservation area.
Assuming the structure is what it appears to be. In bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns the load path at an SW13 address is often not where the drawings suggest, and bathroom renovation priced on that assumption produces variations later. GS Renovation opens up and confirms before quoting a Barnes job. An engineer is appointed wherever the design requires one. Ring 07472 424 226 and we will explain how bathroom renovation confirms the load path at an SW13 address first.
Yes. In Barnes we often create en-suites by borrowing a corner of a bedroom or the awkward space over the stairs, using compact, wall-hung fittings to save room. It needs full tanking, proper drainage falls and good extraction, especially in a period house with timber floors. No planning permission is required for an internal en-suite, though the new wiring is certified under building regulations. We handle the whole job in-house.
We do not think of it as travelling, because Barnes is inside our normal working area. Bathroom renovation projects run across Richmond upon Thames most weeks, so reaching an SW13 address is routine and there is no surcharge for it. GS Renovation also returns for aftercare, which matters more than the initial journey. Ring 07472 424 226 and we will confirm the position. The survey costs a Barnes homeowner nothing. Snagging visits to SW13 are equally routine.
