Working in Southampton
In Southampton we cover SO14, SO15, SO16 and 3 more postcode districts; we also cover Hythe, 3 miles away, and Totton.
Southampton 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 Southampton home, we work out how the shower will get its pressure before choosing a single fitting. If your Southampton loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Supplies across most of Hampshire are hard. If your supply in Southampton 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 your hot-water system and of the pressure and flow you actually get at loft level
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- 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 check of the floor joists where a bath or large shower tray will sit
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.
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.
