Working in Egham
In Egham we cover TW20; we also cover Staines, 2 miles away, and Chertsey.
Homes in and around Egham vary, so we look at the floor, the walls and the water system before we price anything. We quote wet rooms in Egham only after looking at the floor construction, because that is where most of the cost difference lies. If your Egham bathroom is upstairs on timber joists, we check their size and direction before planning the wet room floor.
Water across much of Surrey is hard. If your supply in Egham 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 frameless glass screen fixed to the wall and floor
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
- A pre-formed floor former with a linear or centre drain, or a screed laid to fall
- A thermostatic shower valve, exposed or concealed, with heads to suit your water system
Decisions to make first
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.
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.
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.
