Working in Hatfield
In Hatfield we cover AL9 and AL10; we also cover Welwyn Garden City, 2.8 miles away, and St Albans.
In Hatfield, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Hatfield home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain. If you are planning a wet room in Hatfield 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 Hatfield 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
- Slip-resistant porcelain floor tiles and wall tiling
- Extractor fan and lighting by a qualified electrician, tested and certified, with underfloor heating if you choose it
- Floor strengthening or a ply overlay on timber floors so the surface does not flex
Decisions to make first
Former or screed
A pre-formed board gives a consistent fall and suits timber floors. A sand and cement screed suits concrete slabs and larger shower areas.
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.
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.
