Working in Carshalton
In Carshalton we cover SM1, SM5 and SM6; we also cover Sutton, 1.9 miles away, and Mitcham.
London homes in Carshalton often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Where a Carshalton shower room doubles as the guest bathroom, we plan storage so it stays clear of clutter. If nobody in your Carshalton home has used the bath in a while, a shower room puts that space to better use.
Most of Greater London has very hard water. If your supply in Carshalton 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 survey of water pressure and flow, the hot-water system and the floor where the tray or former will sit
- A thermostatic shower valve, exposed or concealed, with a fixed head, a handset or both
- Tanking to the shower area, then wall and floor tiling
- A basin and WC to suit the space, freestanding or set into a fitted furniture run
Decisions to make first
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.
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.
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.
