Working in Hayes
We work right across Hayes — UB3, UB4 and UB11 — and in neighbouring Southall and Heston.
In Hayes, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Hayes bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor. In a compact Hayes bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet.
Most of Greater London has very hard water. If your supply in Hayes 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
- Strip-out, waste removal, a final flow test to the drain and handover
- A thermostatic shower valve, exposed or concealed, with heads to suit your water system
- Slip-resistant porcelain floor tiles and wall tiling
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
Decisions to make first
Former or screed
A pre-formed board gives a consistent fall and suits timber floors. A sand and cement screed suits concrete slabs and larger shower areas.
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.
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.
