Working in Purley

We cover every part of Purley, including CR2, CR5 and CR8, and nearby Coulsdon (1.7 miles) and South Croydon (1.9 miles).

London homes in Purley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Purley house has a combi boiler, a loft shower can usually run on mains pressure without a pump. For a loft bathroom in a tank-fed Purley home, we work out how the shower will get its pressure before choosing a single fitting.

Supplies across most of Greater London are very hard. If your supply in Purley 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

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

Decisions to make first

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.

Eaves storage

Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.

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 Purley?

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.
