What does a bath to shower conversion cost in Isleworth?
In Isleworth, a bath to shower conversion typically costs £2,500–£6,200 including VAT, based on London prices. Labour costs in London put local prices at about 25% above the UK guide figure. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Isleworth
We cover every part of Isleworth, including TW3, TW5 and TW7, and nearby Hounslow (0.9 miles) and Heston (1.5 miles).
In Isleworth, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If the bath in your Isleworth home is mainly used for storing things, a walk-in shower in the same space is a quick, contained job. For Isleworth houses with only one bath, we talk through whether to keep it before you decide.
Water across much of Greater London is 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
- A thermostatic shower valve, with the pipework moved for the new head position
- Silicone, a full-flow test and a tidy finish where the new tiling meets the old
- A low-profile tray, or a former and tanking for a level-access floor
- A glass enclosure, walk-in panel or frameless screen
Decisions to make first
Low tray or level floor
A low-profile tray has a small lip. A level-access floor removes the step altogether but needs a former, tanking and a linear drain.
Mixer or electric shower
A thermostatic mixer draws on your hot-water system. An electric shower heats cold mains water as it flows and needs its own circuit.
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.
