Which towns do we cover in the Forth Valley?
Water across much of the Forth Valley is soft. If that holds for your street in Stirling, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier. For a loft bathroom in a tank-fed Stirling home, we work out how the shower will get its pressure before choosing a single fitting.
What the job includes
- A check of the floor joists where a bath or large shower tray will sit
- 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
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- 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
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.
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.
Gravity or pumped waste
Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.
Rules that apply in Scotland
A bathroom inside an existing loft room does not usually need planning permission, but forming one is normally building-regulations work because of the new drainage, extract ventilation and electrics. A macerator or pumped WC is acceptable only where the home also has a WC on gravity drainage. Under the water fittings rules, a shower pump must never be connected directly to the mains supply.
In Scotland, forming a new bathroom in the loft or altering the drainage may need a building warrant. The Technical Handbook uses 15 litres per second extract for a bathroom, and water fittings are covered by the Scottish Water Byelaws 2014.
