Working in Crawley
We work right across Crawley — RH10 and RH11 — and in neighbouring Horley and Horsham.
Across a large town like Crawley, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. For a loft bathroom in a tank-fed Crawley home, we work out how the shower will get its pressure before choosing a single fitting. If your Crawley loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Water across much of West Sussex is hard. If your supply in Crawley 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A survey of the headroom across the room, with the usable height marked at each fitting position
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
Decisions to make first
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
Getting the water pressure
A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
