Working in Windsor
In Windsor we cover SL4; we also cover Slough, 1.8 miles away, and Egham.
Homes in and around Windsor vary, so we look at the floor, the walls and the water system before we price anything. We plan shower rooms in Windsor around the waste route first, so the tray has a good fall and drains quickly. Where a Windsor shower room doubles as the guest bathroom, we plan storage so it stays clear of clutter.
Supplies across most of Berkshire are hard. If your supply in Windsor 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 enclosure, walk-in panel or frameless screen in toughened safety glass
- A low-profile tray or a tiled level floor, with the waste positioned for a good fall
- A basin and WC to suit the space, freestanding or set into a fitted furniture run
- A thermostatic shower valve, exposed or concealed, with a fixed head, a handset or both
Decisions to make first
Tray size
A 1200 by 800 mm or 1400 by 900 mm tray with a single panel makes a comfortable walk-in. Go as long as the room allows; length does more than width to keep spray inside.
Glass
8 mm toughened glass is the usual standard for a walk-in panel. An easy-clean coating helps a great deal in hard-water areas.
Rules that apply in England
In England, any change to the wiring in the shower room, or a new circuit for an electric shower, is notifiable under Part P. If you are replacing the fan, keep it at least as effective as the old one; Approved Document F gives 15 litres per second intermittent for a bathroom.
