Working in Portishead

As well as Portishead itself (BS20), we survey in Nailsea, Clevedon and Bishopsworth.

In Portishead, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Portishead house has a combi boiler, a loft shower can usually run on mains pressure without a pump. We plan loft bathrooms in Portishead around the roof line, so the shower sits where you can stand and the eaves become storage.

Most of Somerset has hard water. If your supply in Portishead 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

Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
A survey of the headroom across the room, with the usable height marked at each fitting position
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

Decisions to make first

Gravity or pumped waste

Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.

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 Portishead?

Who handles building control for a loft bathroom in Portishead?

Building control for Portishead 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.
