Working in Chalfont St Peter
As well as Chalfont St Peter itself (SL9), we survey in Gerrards Cross, Rickmansworth and Amersham.
Chalfont St Peter gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We plan loft bathrooms in Chalfont St Peter around the roof line, so the shower sits where you can stand and the eaves become storage. For a loft bathroom in a tank-fed Chalfont St Peter home, we work out how the shower will get its pressure before choosing a single fitting.
Water across much of Buckinghamshire is hard. If your supply in Chalfont St Peter 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- 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
- 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
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.
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.
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.
