Working in Portishead
We work right across Portishead — BS20 — and in neighbouring Nailsea and Clevedon.
Homes in and around Portishead vary, so we look at the floor, the walls and the water system before we price anything. For a wet room in a Portishead flat, the first step is the lease, because freeholder consent is often needed before any work starts. In a compact Portishead bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet.
Water across much of Somerset is hard. If your supply in Portishead is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A frameless glass screen fixed to the wall and floor
- Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
Decisions to make first
Underfloor heating
Electric underfloor heating under the tiles dries the floor quickly after a shower; it is typically £700 to £1,500 for a bathroom.
Floor tile
Matt or textured porcelain with good slip resistance. Mosaic gives extra grip on a centre-drain floor because of its many grout lines.
Rules that apply in England
In England, a new drain connection or changes at the soil stack can be building-regulations work under Part H, and new circuits or changes to the wiring in the room are notifiable under Part P. If the wet room is a newly formed bathroom, Approved Document F requires extract of 15 litres per second intermittent or 8 litres per second continuous.
