Working in Devizes
We cover every part of Devizes, including SN10, and nearby Calne (6.1 miles) and Melksham (6.5 miles).
Being a smaller town does not change how we work in Devizes: free survey, written quote, one team. If your Devizes house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Devizes loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself.
Most of Wiltshire has hard water. If your supply in Devizes 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 check of the floor joists where a bath or large shower tray will sit
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A survey of the headroom across the room, with the usable height marked at each fitting position
Decisions to make first
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
