Working in Bath

We cover every part of Bath, including BA1 and BA2, and nearby Keynsham (6.4 miles) and Trowbridge (7.7 miles).

In a city the size of Bath, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Bath home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Bath loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.

Supplies across most of Somerset are hard. If your supply in Bath 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
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
A check of the floor joists where a bath or large shower tray will sit
A check of your hot-water system and of the pressure and flow you actually get at loft level

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 Bath: questions

What is the price of a loft bathroom in Bath?

A loft bathroom in Bath 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.

Is the water hard in Bath?

Who handles building control for a loft bathroom in Bath?

Building control for Bath 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.

Do I need a pump for a loft shower?

You need a pump if your hot water comes from a cylinder fed by a cold tank, because the tank usually sits at or below the height of a loft shower and gives almost no pressure. A combi boiler or unvented cylinder supplies mains pressure, so no pump is needed, though the flow can drop when other taps run. Shower pumps must only be used on gravity systems, never connected to the mains.
