Working in Banstead

We cover every part of Banstead, including KT17, SM2 and SM7, and nearby Sutton (1.9 miles) and Ewell (2.6 miles).

Homes in and around Banstead vary, so we look at the floor, the walls and the water system before we price anything. We plan loft bathrooms in Banstead around the roof line, so the shower sits where you can stand and the eaves become storage. If your Banstead loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself.

Supplies across most of Surrey are hard. If your supply in Banstead 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 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
A survey of the headroom across the room, with the usable height marked at each fitting position

Decisions to make first

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.

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.

Loft bathrooms in Banstead: questions

How much does a loft bathroom cost in Banstead?

Is the water hard in Banstead?

Who handles building control for a loft bathroom in Banstead?

Building control for Banstead 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.
