Working in Ewell

In Ewell we cover KT4, KT17 and KT19; we also cover Epsom, 1.6 miles away, and Sutton.

Homes in and around Ewell vary, so we look at the floor, the walls and the water system before we price anything. For a loft bathroom in a tank-fed Ewell home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Ewell around the roof line, so the shower sits where you can stand and the eaves become storage.

Supplies across most of Surrey are hard. If your supply in Ewell 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 survey of the headroom across the room, with the usable height marked at each fitting position
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
A check of your hot-water system and of the pressure and flow you actually get at loft level
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

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.

Is the water hard in Ewell?

Who handles building control for a loft bathroom in Ewell?

Building control for Ewell 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 long does a loft bathroom take?

Allow 6–12 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Ewell.

How much headroom do you need for a loft shower?

Plan for around 2 m of clear height over the whole shower area, and enough standing height in front of the basin and WC. A bath can sit lower under the slope as long as you can stand up where you get in and out. We mark the usable height at each position on the survey drawing.
