Working in Ruislip
In Ruislip we cover HA4, HA5 and UB10; we also cover Northolt, 2.9 miles away, and Uxbridge.
London homes in Ruislip often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We quote wet rooms in Ruislip only after looking at the floor construction, because that is where most of the cost difference lies. If your Ruislip home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
Supplies across most of Greater London are very hard. If your supply in Ruislip 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 pre-formed floor former with a linear or centre drain, or a screed laid to fall
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- A thermostatic shower valve, exposed or concealed, with heads to suit your water system
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
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.
Screen size
A screen of 1200 mm or more keeps spray off the rest of the room in most layouts. In a very small wet room, expect the whole floor to get wet.
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.
