Working in St Austell

We cover every part of St Austell, including PL25, and nearby Bodmin (9.2 miles) and Truro (13.5 miles).

Being a smaller town does not change how we work in St Austell: free survey, written quote, one team. If your St Austell loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. For a loft bathroom in a tank-fed St Austell home, we work out how the shower will get its pressure before choosing a single fitting.

Supplies across most of Cornwall are soft. If that holds for your street in St Austell, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
A check of the floor joists where a bath or large shower tray will sit
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
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

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.

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.

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 St Austell?

Who handles building control for a loft bathroom in St Austell?

Building control for St Austell 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 St Austell.

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.
