What does a loft bathroom cost in Ascot?

Working in Ascot
In Ascot we cover GU20, RG12 and SL5; we also cover Bracknell, 3.3 miles away, and Egham.
Ascot gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For a loft bathroom in a tank-fed Ascot home, we work out how the shower will get its pressure before choosing a single fitting. If your Ascot home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Water across much of Berkshire is hard. If your supply in Ascot 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
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A check of the floor joists where a bath or large shower tray will sit
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
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.
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
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.
