Working in Warminster

In Warminster we cover BA12; we also cover Westbury, 3.9 miles away, and Frome.

Warminster gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Warminster loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. We plan loft bathrooms in Warminster around the roof line, so the shower sits where you can stand and the eaves become storage.

Water across much of Wiltshire is hard. If your supply in Warminster 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 survey of the headroom across the room, with the usable height marked at each fitting position
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A check of your hot-water system and of the pressure and flow you actually get at loft level
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system

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.

Where the shower goes

Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.

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 Warminster?

Who handles building control for a loft bathroom in Warminster?

Building control for Warminster is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How do you ventilate a loft bathroom?

A loft bathroom fan is usually ducted through the roof to a tile or slate vent, or out through a gable wall. The duct should be insulated where it crosses a cold space, so condensation does not run back into the fan. A roof window helps with daylight and airing but does not replace the fan.
