Working in Chippenham

As well as Chippenham itself (SN14 and SN15), we survey in Calne, Melksham and Devizes.

In Chippenham, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For a loft bathroom in a tank-fed Chippenham home, we work out how the shower will get its pressure before choosing a single fitting. If your Chippenham house has a combi boiler, a loft shower can usually run on mains pressure without a pump.

Water across much of Wiltshire is hard. If your supply in Chippenham 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
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it

Decisions to make first

Getting the water pressure

A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.

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.

Is the water hard in Chippenham?

Is a bath too heavy for a loft floor?

A standard acrylic bath is usually fine on a loft floor built for a conversion, but a filled bath with someone in it is heavy, and stone-resin or cast-iron baths are much heavier still. We check the joist size, span and direction at the survey, and a heavy bath may need a structural check and strengthening first.
