Supplies across most of Derbyshire are moderately hard. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Derby. Hardness varies street by street, so check the figure for your postcode with your water supplier. For a loft bathroom in a tank-fed Derby home, we work out how the shower will get its pressure before choosing a single fitting.
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
- 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 shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- 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
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.
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.
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.
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
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.
