Bathroom Renovation Surbiton

GS Renovation fits bathrooms and en-suites across Surbiton, making the most of the tight spaces in KT6's Victorian and Edwardian houses and converted flats. We handle waterproofing, drainage, tiling, heating and every fixture, so a dated period bathroom becomes a properly built, watertight room.

In Surbiton, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Surbiton: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Surbiton home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Wet rooms and tanking in Surbiton homes

Many Surbiton bathrooms sit in the old rear closet wing or a first-floor return, where the floors are timber and the walls are solid brick. Getting the waterproofing right on these surfaces matters, so we tank the wet areas fully before any tile goes on, rather than relying on grout to keep water out. For walk-in showers and wet rooms we form a properly graded fall to the drain and seal every junction, which is what stops leaks reaching the rooms below.

Ventilation and drainage need real thought in these older houses, where soil pipes and joist runs were never planned for modern bathrooms. We set out extraction to clear moisture and prevent damp, and route new waste so it falls correctly to the existing stack. On the timber floors typical of KT6 period houses we make sure the structure can carry a stone or large-format tile before we commit to the finish.

Housing in Surbiton

Of the 7,740 homes the valuation list records in Surbiton, 34% were built before 1919, 10% between the wars and 56% since 1945; 78% are flats and 22% are houses. Most homes here are flats, and a bathroom in a flat in Surbiton sits over a neighbour's ceiling, so tanking comes first.

New bathrooms in divided Surbiton villas are notifiable work

Adding a bathroom where there was none is the formation of a new bathroom, and Kingston charges for it as a building control item, the same for full plans or building notice and more for regularisation. In Surbiton, where 78% of homes are flats, a second shower room or an en-suite in a divided villa goes wherever the flat has space, which may be over a neighbour's bedroom or kitchen. The drainage then decides the design, because the new waste must reach the soil stack at a proper fall, and in a divided villa that stack usually belongs to the freeholder.

A flat has no householder permitted development rights, so a new soil pipe on the outside needs permission where it changes the building's appearance. In a conservation area even a house loses that cover for a pipe on a wall facing the road. Surbiton has several conservation areas, including the Claremont Road Conservation Area, which was extended in July 1991 and has 391 properties. So where a new bathroom cannot reach the existing stack inside the building, a pumped waste is the usual alternative to a new external pipe. We settle that at survey, before the layout is drawn, because it fixes where the WC can go.

Space-saving en-suites in KT6 homes

Adding an en-suite to a Surbiton house or flat usually means carving space from a bedroom or borrowing from the landing, so every millimetre counts. We plan compact layouts around wall-hung basins and toilets, sliding or pivot shower doors and concealed cisterns, keeping the room usable without feeling cramped. Underfloor heating frees the wall space a radiator would take and warms tiled floors that otherwise feel cold underfoot in a period house.

In the main family bathroom we work with the awkward proportions these older homes throw up, sloping ceilings under the roof, chimney breasts and narrow returns, turning them into recessed storage or a neat shower enclosure. Tiling, sanitaryware, heating and lighting are all fitted by the same team to a proper finish. Across KT6 we make small period bathrooms feel considered and generous rather than merely squeezed in.
