Working in Carshalton
We cover every part of Carshalton, including SM1, SM5 and SM6, and nearby Sutton (1.9 miles) and Mitcham (2.4 miles).
In Carshalton, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If someone in your Carshalton home is finding the bath side harder to step over, a low or level-access tray removes the problem. If you are applying for a grant towards a bath to shower conversion in Carshalton, we provide the itemised written quote the council will ask for.
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
- Repair or replacement of floorboards where the bath has left them soft or damaged
- A thermostatic shower valve, with the pipework moved for the new head position
- A glass enclosure, walk-in panel or frameless screen
- A low-profile tray, or a former and tanking for a level-access floor
Decisions to make first
Your only bath?
If this is the only bath in the house, think about whether you, or a future buyer, will want one before you commit.
Enclosure or walk-in
An enclosure with a door keeps all the water in and suits a shorter space. A walk-in panel makes the most of the full 1700 mm length an old bath leaves.
Rules that apply in England
In England, adding an electric shower usually means a new circuit, which is notifiable under Part P, as is any change to the wiring in the bathroom. Where the conversion is an adaptation for a disabled person, a Disabled Facilities Grant of up to £30,000 may help, but the council must approve it before work starts.
