Working in Carshalton
We work right across Carshalton — SM1, SM5 and SM6 — and in neighbouring Sutton and Mitcham.
London homes in Carshalton often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Carshalton shower enclosure has a leaking door seal or a cracked tray, a walk-in panel removes the door altogether. If your Carshalton bathroom has a bath that nobody uses, a walk-in shower in the same space is often a two or three day job.
Water across much of Greater London is very hard. 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
- Tanking to the shower walls, and to the floor where it is tiled
- A survey of the space, the waste position, water pressure and the hot-water system
- Removal of the old bath or enclosure and making good to the walls and floor
- An 8 mm or 10 mm toughened glass panel with a wall profile and support arm, or a frameless fixing
Decisions to make first
Tray or tiled floor
A tray is quicker, costs less and has a small lip. A tiled floor with a linear drain sits level with the rest of the room and lets one tile run throughout.
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.
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.
