Working in Holloway
In Holloway we cover N7, N19 and NW5; we also cover Highbury, 1.1 miles away, and Archway.
London homes in Holloway often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We quote wet rooms in Holloway only after looking at the floor construction, because that is where most of the cost difference lies. If your Holloway bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.
Supplies across most of Greater London are very hard. If your supply in Holloway 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 thermostatic shower valve, exposed or concealed, with heads to suit your water system
- Strip-out, waste removal, a final flow test to the drain and handover
- Slip-resistant porcelain floor tiles and wall tiling
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
Decisions to make first
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.
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.
