Working in Isleworth
We work right across Isleworth — TW3, TW5 and TW7 — and in neighbouring Hounslow and Heston.
In Isleworth, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If nobody in your Isleworth home has used the bath in a while, a shower room puts that space to better use. We plan shower rooms in Isleworth around the waste route first, so the tray has a good fall and drains quickly.
Most of Greater London has very hard water. If your supply in Isleworth 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
- Recessed niches or shelving in the shower wall
- Removal of the old bath and suite, waste removal, testing and handover
- A low-profile tray or a tiled level floor, with the waste positioned for a good fall
- An enclosure, walk-in panel or frameless screen in toughened safety glass
Decisions to make first
Storage
With no bath, there is often space for a full-width vanity unit or a tall cupboard for towels.
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.
