Working in Finchley
As well as Finchley itself (N2, N3 and N12), we survey in Muswell Hill, Cricklewood and Kilburn.
In Finchley, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Finchley bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor. We quote wet rooms in Finchley only after looking at the floor construction, because that is where most of the cost difference lies.
Water across much of Greater London is very hard. If your supply in Finchley 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
- 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
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
Decisions to make first
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.
Open or screened
A fully open shower with no glass only works in a larger room, with the basin, WC and towels well away from the spray.
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.
