Working in Portsmouth
We cover every part of Portsmouth, including PO1, PO2, PO3 and 3 more postcode districts, and nearby Gosport (1.7 miles) and South Hayling (5.1 miles).
Portsmouth is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. For a loft bathroom in a tank-fed Portsmouth home, we work out how the shower will get its pressure before choosing a single fitting. If your Portsmouth house has a combi boiler, a loft shower can usually run on mains pressure without a pump.
Supplies across most of Hampshire are hard. If your supply in Portsmouth 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
- 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
Decisions to make first
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
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.
