Working in Barnet
We cover every part of Barnet, including EN4, EN5, HA8 and 7 more postcode districts, and nearby Potters Bar (3.1 miles) and Borehamwood (3.3 miles).
London homes in Barnet often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Barnet home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain. For a wet room in a Barnet flat, the first step is the lease, because freeholder consent is often needed before any work starts.
Most of Greater London has very hard water. If your supply in Barnet 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
- Slip-resistant porcelain floor tiles and wall tiling
- A frameless glass screen fixed to the wall and floor
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
- Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
Decisions to make first
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.
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.
