GS Renovation builds bathrooms, wet rooms and en-suites across Dulwich, making the most of the awkward spaces that come with SE21's Victorian and Edwardian terraces. With over 30 years in South London, we handle the waterproofing, drainage, tiling, heating and ventilation properly, so your bathroom near Dulwich Park stays dry and warm for the long term.
Waterproofing and wet rooms in Dulwich
A bathroom is only as good as what sits behind the tiles, so we tank and waterproof thoroughly before anything is fixed. This matters in Dulwich's older terraces, where timber floors and solid walls move and settle over the years and a poorly sealed shower will find every weakness. For walk-in showers and full wet rooms we form falls to the drain correctly and bond the tanking into the surrounding surfaces.
We also sort the parts nobody sees but everyone feels. Old SE21 houses often have long or shallow soil runs and tired ventilation, so we upgrade the drainage and fit proper extraction to keep humidity, mould and condensation under control. Underfloor heating goes in where the floor build-up allows, giving you a warm, dry bathroom that suits a solid-walled period home rather than fighting against it.
Space-saving layouts for SE21 period homes
Bathrooms in Dulwich terraces are often tucked onto a half-landing or squeezed into the end of the closet wing, so clever planning matters more than square footage. We rework the layout to make every inch count, choosing wall-hung sanitaryware, slimline concealed cisterns and walk-in showers that open up a tight room, while keeping the proportions sympathetic to the age of the house.
Adding an en-suite to a main bedroom is a popular SE21 upgrade, and we plan the drainage, waterproofing and ventilation to work within the existing structure without weakening it. Internal bathroom work does not need planning permission, though the electrics are notifiable under the Building Regulations, so we make sure every new circuit near water is correctly certified. The finish, from tiling to lighting, is handled by the same team throughout.
