Luxury bathroom and wet-room refurbishment in Wallington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms across Wallington, from compact family bathrooms in SM6 terraces to en-suites in the larger Edwardian houses. With over 30 years of experience, we handle the waterproofing, the drainage, the tiling and the finish in-house, so your new bathroom is watertight, well ventilated and properly built to last.

A bathroom that lasts starts with proper waterproofing. Before any tile goes on, we tank the walls and floor of showers and wet rooms with a fully bonded membrane, so water cannot track into the structure of these older Wallington houses. Wet rooms and level-access walk-in showers suit period homes well, but they only work if the falls, the drainage and the tanking are right, which is exactly the part we never cut corners on.
Good drainage and ventilation matter just as much as the finish. We set the pipework to drain cleanly, which sometimes means raising a floor or boxing in a soil pipe on a Wallington terrace, and we fit extraction that clears moisture properly rather than leaving it to sit and cause damp. Getting these hidden details right is what keeps a bathroom fresh, dry and free of the black mould that plagues poorly built rooms.
Bathrooms in Wallington's terraces are often tucked into the rear closet wing or a converted box room, so every centimetre counts. We plan layouts that make a small space feel generous, using wall-hung basins and toilets, walk-in showers in place of bulky enclosures, and fitted storage that keeps clutter out of sight. Careful positioning of the sanitaryware means even the tightest period bathroom can hold everything a family needs without feeling cramped.
Underfloor heating is a favourite in these houses, freeing up wall space and warming the floor of a room that can otherwise feel cold. We lay it beneath tile or stone, then tile the walls and floor to a high standard, sealing everything against moisture. Where there is room, we add en-suites to main bedrooms, running the necessary plumbing and ventilation, and certify the electrics as building regulations require for a bathroom.
Wallington homeowners choose GS Renovation for bathrooms because we get the hidden work right, the tanking, the drainage and the ventilation, not just the tiling you can see. One team fits the whole room, so there are no gaps between trades and no finger-pointing if something goes wrong. More than 30 years across SM6 stands behind every bathroom we build.

FAQ
Location itself is not a line on our quotation. Two South London homes of the same age and construction get similar bathroom renovation figures, and what separates them is condition and access at the SM6 address. GS Renovation does not charge Wallington homeowners a premium for the address, and there is no travel surcharge within Sutton. The survey establishes the rest. Ring 07472 424 226 with the SM6 postcode and we will confirm before quoting. 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.
Longer than the fastest quote you will be given, and shorter than an open-ended one. GS Renovation would rather set bathroom renovation dates a Wallington homeowner can plan around than win the SM6 job on a programme nobody can meet. The stages, the trades and the Sutton Council points are all written down. You are updated against them weekly throughout the Sutton project. Ring 07472 424 226 and we will describe how a comparable SM6 project ran.
Yes, and we will give you addresses rather than testimonials. Seeing finished bathroom renovation work near SM6 or elsewhere in Wallington tells you far more than anything written down. GS Renovation also holds 31 public MyBuilder reviews and a 4.9 rating. Ring 07472 424 226 and we will arrange for you to speak to a previous Sutton client directly. Nothing is arranged in advance with those Sutton clients, and nothing at SM6 is rehearsed.
Yes. Bathroom electrics in Wallington are notifiable under Part P and must be certified, and drainage, ventilation and any structural change must meet building regulations. GS Renovation includes certified electrical work and manages Sutton Council building control on every SM6 bathroom.
By working with the original construction rather than against it. Bathroom renovation at an SM6 address of that age uses methods suited to aged materials, and Sutton Council expects to see that reflected in the application. GS Renovation sets the sequence out in the Wallington programme before starting. Nothing structural is touched until an engineer has confirmed the load path. Ask on 07472 424 226 about the bathroom renovation method proposed for an SM6 property of that age.
Yes. Wet rooms work well in the smaller bathrooms of Wallington's period terraces, giving level access and a more open feel. The key is thorough tanking, the correct floor falls and proper drainage, which we always install before tiling. We also make sure ventilation is adequate so the room stays dry. Done properly, a wet room is one of the most practical ways to use a tight space.
