Working in Weymouth

In Weymouth we cover DT3 and DT4; we also cover Dorchester, 7.2 miles away, and Poole.

In Weymouth, 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 Weymouth home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Weymouth around the roof line, so the shower sits where you can stand and the eaves become storage.

Water across much of Dorset is hard. If your supply in Weymouth 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 your hot-water system and of the pressure and flow you actually get at loft level
A check of the floor joists where a bath or large shower tray will sit
A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces

Decisions to make first

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.

Eaves storage

Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.

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 Weymouth?

Who handles building control for a loft bathroom in Weymouth?

Building control for Weymouth 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 long does a loft bathroom take?

Allow 6–12 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Weymouth.

Can you put a toilet in a loft?

Yes, if the waste can fall to the soil stack or a macerator can be used. Gravity drainage is the first choice; a macerator is only allowed where the home already has a WC on gravity drainage, which in most houses means the main bathroom.
