Wet rooms and walk-in showers in Bexleyheath
Interwar Bexleyheath bathrooms are often a modest size with an original layout that wastes space. Converting to a walk-in shower or full wet room opens the room up, but it only works if the waterproofing is right, so we tank the floor and walls properly before tiling and set the drainage to fall correctly toward the outlet.
Good ventilation matters just as much in these 1930s homes, so we fit extraction that clears moisture and protects your finishes for the long term. Underfloor heating warms the tiles underfoot, and careful tiling and lighting turn a cramped interwar bathroom into a space that feels calm and genuinely modern.
Housing in Bexleyheath
Roughly 8,550 dwellings sit on the valuation list for Bexleyheath. 73% are houses and 27% flats, and by age 19% predate 1919, 40% are interwar and 41% post-war. 41% of homes here are semi-detached; a semi in Bexleyheath can vent its bathroom through the flank.
En-suites for a Bexleyheath house let by the room
Adding en-suites to let a Bexleyheath house by the room starts with planning, not plumbing. Bexley's borough-wide Article 4 Direction on small houses in multiple occupation came into force on 24 September 2017, so changing a family house into a small shared house is under planning control throughout the borough. Get that answer before the bathrooms are designed. Each en-suite also adds a new waste and extract route, and in a two-storey house those routes compete for the same joist runs and the same rear soil stack.
The age of the Bexleyheath house decides how easy that is. 19% of homes here were built before 1919 and 40% between 1919 and 1939. An older house can have one soil stack at the back and floor joists running front to back, so an en-suite at the front needs its waste to run with the joists or to find a new stack. The structural engineer we appoint checks any notching or trimming, and the extract routes are planned before the ceilings are closed, since each en-suite needs its own ventilation.
En-suites and space-saving layouts in DA6 homes
Many Bexleyheath owners want an en-suite off the main bedroom, and interwar semis usually have the room to borrow from a landing, a box room or a corner of a larger bedroom. We plan the layout around existing soil pipes and joists, keeping new pipework runs sensible so the shower drains and the basin fills exactly as it should.
Bathroom renovation of this kind needs no planning permission, though the electrics and any notifiable work fall under building regulations, with the electrics certified by a registered electrician or notified to building control. From compact en-suites to reconfigured family bathrooms, we make period Bexleyheath homes work harder with clever, watertight layouts finished to a high standard.
A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Bexley Council, and doing it without consent is a criminal offence.

FAQ
Frequently Asked Questions about Bathroom Renovation Bexleyheath
Can you quote bathroom renovation for a DA6 property over the phone?
GS Renovation will not give a real quotation for bathroom renovation in Bexleyheath over the phone, only the range, £6,000 to £20,000 or more (indicative). On 07472 424 226 we can explain what moves the cost and whether the job needs Part F extraction to outside, and Part P certification for any new circuit, but the DA6 property has to be seen first. Builders who quote blind across Bexley revise the figure once the floor or walls are opened.
Can you fit an en-suite in my 1930s Bexleyheath house?
Usually yes. Interwar Bexleyheath semis often have enough space to take an en-suite from a landing, box room or the corner of a larger bedroom. We plan the layout around the existing soil pipe and joists to keep drainage reliable. No planning permission is needed, but the notifiable electrics are certified by a registered electrician.
How long will our Bexleyheath bathroom be out of use?
Most DA6 bathrooms take 10 to 15 working days. The stage nobody can hurry is curing the tanking membrane under the tiles, and a floor levelled with compound needs drying time as well. Where the house has no second toilet, we plan the pan to go back on overnight wherever the work allows, and warn you of the exceptions a day or two ahead.
Can a wet room go over the timber floor of a Bexleyheath bathroom?
Yes, with the floor built for it. On the upper floor of a 1930s Bexleyheath house the old boards are replaced with stiff ply, sometimes set down between the joists to create the fall, and a former sits under the drain. The joist direction decides where the waste can run. Tanking goes over everything and up the walls before tiling, because any flex cracks grout and lets water in.
Where can the toilet go in a Bexleyheath bathroom refit?
Close to the soil stack, which in many 1930s houses runs down the outside wall. The pan needs a short run with a good fall, so moving it across the room means a longer connection or a new branch. Replacing an old cast iron stack is a sensible time to fit it.
Which electrical rules apply in a Bexleyheath bathroom?
Part P makes new circuits, and changes to circuits around the bath or shower, notifiable, so the circuits for lights, fan, shaver point and any heated rail or mat are signed off by a registered electrician. Fittings near the bath or shower must carry the rating for their zone, which narrows the choice of spotlights over a walk-in tray. In an interwar DA6 semi, the strip-out sometimes exposes an old lighting circuit with no earth, which is replaced at the same time.
What protects the neighbour below a new bathroom in a Bexleyheath flat?
Membrane, testing and the lease. 27% of Bexleyheath homes are flats, so a bathroom here can sit directly over someone else's ceiling. A waterproof membrane goes under all wet areas, not just the shower, and the waste joints are pressure tested before the floor is closed. Some leases also require the freeholder's consent before a bath becomes a walk-in shower, so read yours before choosing a layout.
Does an external soil pipe on a Bexleyheath conservation area house need permission?
It may. Bexley has 23 conservation areas across the borough and special controls apply to buildings in them. In a conservation area, a new soil and vent pipe on the front wall, or on a side wall facing a road, is not permitted development, so ask Bexley's planning team first. Running the new waste internally to an existing rear stack avoids the question and keeps the front elevation as it is.
Can a walk-in shower tray be recessed into a Bexleyheath bathroom floor?
Sometimes, depending on the floor. 12% of Bexleyheath homes were built in 2000 or later, and newer houses can have engineered joists that cannot be cut down to recess a tray. An older house with sawn joists may allow it, with the structural engineer we appoint checking the reduced depth. Where neither works, a slim raised tray with a short step gives the same shower without touching the structure.
