Working in Streatham
We cover every part of Streatham, including SE27, SW12 and SW16, and nearby Mitcham (2.4 miles) and Brixton (2.8 miles).
London homes in Streatham often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We plan loft bathrooms in Streatham 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 Streatham home, we work out how the shower will get its pressure before choosing a single fitting.
Supplies across most of Greater London are very hard. If your supply in Streatham 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 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
- 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
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.
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.
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.
