Working in Walthamstow
In Walthamstow we cover E4, E10, E11 and 1 more postcode districts; we also cover Leytonstone, 2 miles away, and Tottenham.
London homes in Walthamstow often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We plan loft bathrooms in Walthamstow around the roof line, so the shower sits where you can stand and the eaves become storage. If your Walthamstow house has a combi boiler, a loft shower can usually run on mains pressure without a pump.
Water across much of Greater London is very hard. If your supply in Walthamstow 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- A survey of the headroom across the room, with the usable height marked at each fitting position
- 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
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
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.
