Working in Northolt
In Northolt we cover HA2, UB5 and UB6; we also cover Greenford, 1.5 miles away, and Harrow.
In Northolt, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If you are planning a wet room in Northolt for level access, we design the fall and drain so the floor is flush from the doorway. If your Northolt home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
Water across much of Greater London is very hard. If your supply in Northolt 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
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- 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
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
Decisions to make first
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.
Linear or centre drain
A linear drain along one wall lets the floor fall in a single direction, so large tiles can be laid without awkward cuts. A centre drain needs a four-way fall and suits smaller tiles or mosaic.
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.
