Working in Isleworth
As well as Isleworth itself (TW3, TW5 and TW7), we survey in Hounslow, Heston and Southall.
London homes in Isleworth often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For a walk-in shower in Isleworth, we check the water pressure first, so the head you choose will actually perform. If you are planning ahead in Isleworth for easier access, a low-profile walk-in tray gives most of the benefit without a full wet room.
Supplies across most of Greater London are very hard. 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
- Silicone, a full-flow test for leaks and spray, and handover
- Tanking to the shower walls, and to the floor where it is tiled
- A thermostatic valve with a riser rail, a fixed head or both
- A survey of the space, the waste position, water pressure and the hot-water system
Decisions to make first
Valve
An exposed bar valve with a riser rail is easy to fit and service. A concealed valve hides the pipework and suits a fixed overhead head.
Tray length
Go long rather than wide. A 1400 to 1700 mm tray with a 900 to 1200 mm panel leaves a dry walkway; a 1200 mm tray works but gives less margin for spray.
Rules that apply in England
In England, moving or adding lights, a fan or a shower circuit in a room with a bath or shower is notifiable under Part P. A tiled level floor that needs a new drain connection at the soil stack can bring in Part H.
