Working in Coulsdon

In Coulsdon we cover CR5, CR8 and SM7; we also cover Purley, 1.7 miles away, and Banstead.

In Coulsdon, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For a loft bathroom in a tank-fed Coulsdon home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Coulsdon around the roof line, so the shower sits where you can stand and the eaves become storage.

Supplies across most of Greater London are very hard. If your supply in Coulsdon 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
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A check of the floor joists where a bath or large shower tray will sit
A survey of the headroom across the room, with the usable height marked at each fitting position

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.

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 Coulsdon: questions

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

Is the home survey in Coulsdon really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

Do you cover CR5 in Coulsdon?

Yes. We cover all of Coulsdon, including CR5, CR8 and SM7, and nearby Purley, Banstead and Sutton. Survey visits are free and arranged at a time that suits you.

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.
