Working in Melksham
We work right across Melksham — SN12 — and in neighbouring Trowbridge and Chippenham.
Being a smaller town does not change how we work in Melksham: free survey, written quote, one team. For a loft bathroom in a tank-fed Melksham home, we work out how the shower will get its pressure before choosing a single fitting. If your Melksham house has a combi boiler, a loft shower can usually run on mains pressure without a pump.
Water across much of Wiltshire is hard. If your supply in Melksham 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 drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
Decisions to make first
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.
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.
