Working in Harpenden
We work right across Harpenden — AL5 — and in neighbouring St Albans and Luton.
Homes in and around Harpenden vary, so we look at the floor, the walls and the water system before we price anything. We quote wet rooms in Harpenden only after looking at the floor construction, because that is where most of the cost difference lies. If you are planning a wet room in Harpenden for level access, we design the fall and drain so the floor is flush from the doorway.
Most of Hertfordshire has very hard water. If your supply in Harpenden 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 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
- Strip-out, waste removal, a final flow test to the drain and handover
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.
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.
