Working in Welwyn Garden City
We cover every part of Welwyn Garden City, including AL7 and AL8, and nearby Hatfield (2.8 miles) and Hertford (5.5 miles).
Homes in and around Welwyn Garden City vary, so we look at the floor, the walls and the water system before we price anything. For a wet room in a Welwyn Garden City flat, the first step is the lease, because freeholder consent is often needed before any work starts. If you are planning a wet room in Welwyn Garden City for level access, we design the fall and drain so the floor is flush from the doorway.
Supplies across most of Hertfordshire are very hard. If your supply in Welwyn Garden City 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
- Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
- 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.
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.
