Wet rooms and walk-in showers in Tooting
Wet rooms and walk-in showers are popular in Tooting, but they only work if the waterproofing is done properly. On the suspended timber floors typical of these terraces, we form the falls, fully tank the floor and walls, and bond the tiles onto a waterproof system rather than relying on grout alone. Getting the drainage right matters too, so we set the gully and pipework to fall correctly into the existing soil stack without ponding or leaks.
Ventilation is the other essential in a period Tooting house, because a solid-wall bathroom holds damp if the moist air has nowhere to go. We fit proper extraction, add underfloor heating to keep the room warm and the floor dry, and choose tiling and finishes that suit both the age of the house and daily family use. The result is a warm, watertight bathroom that will not suffer the black mould and failing seals of a poorly built one.
Housing in Tooting
The stock in Tooting runs to roughly 23,930 dwellings, 62% of them flats and 38% houses, built 67% before 1919, 8% between 1919 and 1939 and 24% after 1945. Since most homes here are flats, a bathroom in a flat in Tooting sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.
Bathrooms over someone else's ceiling in Tooting flats
62% of homes in Tooting are flats, so a new bathroom may well sit over a neighbour's rooms rather than your own. That changes the priorities. The waste has to reach a shared soil stack with enough fall, which in a converted house means working with the joist direction rather than against it, and a properly tanked floor matters more when a failure lands in another home. Ask the freeholder what the lease says about bathroom positions, flooring and sound insulation before the layout is drawn, because moving a bathroom over a bedroom below can be restricted.
Listed buildings add a second layer. Wandsworth has around 500 listed buildings, and consent is needed for interior alterations that affect a listed building's special character. In a bathroom that can mean the route of a new soil pipe through an original floor, boxing in a period fireplace, or taking out a panelled door to fit a pocket door. Check whether your Tooting address is listed before the plumber plans the runs, because listed building consent has to be in place before the first joist is notched.
En-suites and space-saving layouts in Tooting
Finding room for an extra bathroom in a Tooting terrace usually means being clever with space. We often carve an en-suite or a second bathroom out of a bedroom corner, the closet wing, or the space over the stairs, using compact fittings, walk-in showers and hidden cisterns to fit a full bathroom into a tight footprint. Careful planning of the drainage runs back to the soil stack keeps these new rooms practical rather than a plumbing compromise.
The original family bathroom in an SW17 terrace is often the old closet wing off the half-landing, a narrow, cold room that needs rethinking. We reconfigure the layout, reposition the soil and waste, upgrade the ventilation and heating, and tank and tile it to a high standard. New circuits and circuit changes near the bath or shower are notifiable under Part P, so the wiring and any electric underfloor heating are certified by a registered electrician or notified to building control, and everything is finished by one team from strip-out to the final seal.

FAQ
Frequently Asked Questions about Bathroom Renovation Tooting
How much should bathroom renovation in Tooting cost?
Expect bathroom renovation at a Tooting address to cost £6,000 to £20,000 or more (indicative), with the property rather than the postcode deciding the figure. At the SW17 survey GS Renovation confirms the detail that matters most, because soil stack distance decides where a Tooting WC can go. Labour, materials and any Wandsworth Council building control fee are then itemised, so another Wandsworth quotation can be compared line by line.
Can you fit an en-suite into my Tooting Victorian terrace?
Usually yes. In Tooting terraces we create en-suites from a bedroom corner, the closet wing or the space over the stairs, using compact fittings and hidden cisterns to work within a tight footprint. The key is planning the drainage back to the soil stack and getting the tanking and ventilation right. An en-suite needs building regulations sign-off for the electrics and drainage, but not planning permission.
How close must the toilet stay to the soil stack in a Tooting bathroom?
Close enough for its waste to fall steadily without crossing joists. In a Victorian terrace the stack usually runs down the back addition's outside wall, so a toilet on that wall connects easily. Moving it across the room may need a raised floor. In a flat, the stack is shared, and the freeholder usually has to consent to relocating it.
Can a Tooting ground-floor flat bathroom have a wet room?
Often, but the floor type decides the method. A suspended timber floor is stiffened and a pre-formed tray former set between joists to create falls. A solid floor is broken out to form the drain and screeded to falls. Either way, the whole room is tanked before any tile, and the drain position is fixed at the start.
How long is a Tooting bathroom out of use?
About 10 to 15 working days from strip-out to finished room. Pipework and wiring go in first, the waste falls are set, the area is tanked and checked, then tiling, sanitaryware and electrics. If it is the only bathroom, the toilet can often be kept working overnight during the early stages.
What decides the shower type in a Tooting flat?
The hot water system. A combi gives mains-pressure water for one outlet at a time, so a thermostatic mixer suits it. An older flat with a hot water cylinder and cold tank may give low pressure, needing a pump or an electric shower. Any boiler work is done by a Gas Safe engineer. Decide before first fix, since pipe sizes and valve types follow the system.
Does a new roof vent for a Tooting bathroom need permission on the Heaver Estate?
Possibly. Under the Heaver Estate Conservation Area Article 4 direction, changes to the roofs of houses need planning permission, and a new soil vent or extract terminal through the roof slope is a change to the roof. Routing the extract through a rear wall, or into an existing vent pipe, may avoid the question entirely. Where the roof is the only route, ask the planning team before the scaffold goes up.
Can a soil pipe run down the outside wall of a Tooting flat?
Expect to need planning permission for it. Wandsworth's conservation area guidance says flats, and houses converted to flats, have no permitted development rights, so an external change to one of these buildings needs planning permission. A new soil pipe on the wall is an external change. The freeholder will also need to consent under the lease. An internal route through a boxed riser is often quicker, provided the fall works and there is access for rodding.
How much notice does Wandsworth need before bathroom work that involves building control?
Two steps. Wandsworth Building Control wants your application in 48 hours ahead of the start on site, and then a further 24 hours of warning before work begins. That applies where the bathroom includes notifiable work such as new drainage or a structural change to the floor. Submit when the start date is agreed, then give the shorter notice the day before work starts, so the first inspection can be booked around the pipework.
