Working in Aylesbury
As well as Aylesbury itself (HP19, HP20 and HP21), we survey in Leighton Buzzard, Berkhamsted and Chesham.
In Aylesbury, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For a loft bathroom in a tank-fed Aylesbury home, we work out how the shower will get its pressure before choosing a single fitting. If your Aylesbury house has a combi boiler, a loft shower can usually run on mains pressure without a pump.
Supplies across most of Buckinghamshire are hard. If your supply in Aylesbury 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A check of your hot-water system and of the pressure and flow you actually get at loft level
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.
