Most of Hertfordshire has very hard water. If your supply in Watford 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. For a loft bathroom in a tank-fed Watford home, we work out how the shower will get its pressure before choosing a single fitting.
What the job includes
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A survey of the headroom across the room, with the usable height marked at each fitting position
- 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Decisions to make first
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.
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.
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.
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.
Rules that apply in England
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 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.
