Working in Dorchester

In Dorchester we cover DT1; we also cover Weymouth, 7.2 miles away, and Yeovil.

Being a smaller town does not change how we work in Dorchester: free survey, written quote, one team. For a loft bathroom in a tank-fed Dorchester home, we work out how the shower will get its pressure before choosing a single fitting. If your Dorchester home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.

Water across much of Dorset is hard. If your supply in Dorchester 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 drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
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

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.

Bath or no bath

A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.

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.

More about loft bathrooms

Loft bathrooms in Dorchester: questions

How much should I budget for a loft bathroom in Dorchester?

A loft bathroom in Dorchester usually costs £6,600–£13,250 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Do you cover DT1 in Dorchester?

Yes. We cover all of Dorchester, including DT1, and nearby Weymouth, Yeovil and Poole. Survey visits are free and arranged at a time that suits you.

Is the water hard in Dorchester?

Who handles building control for a loft bathroom in Dorchester?

Building control for Dorchester 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.
