Which towns do we cover in Powys?
Water across much of Powys is soft. If that holds for your street in Newtown, 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. We plan loft bathrooms in Newtown around the roof line, so the shower sits where you can stand and the eaves become storage.
What the job includes
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- A check of the floor joists where a bath or large shower tray will sit
- 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 shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
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.
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.
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.
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
Rules that apply in Wales
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.
Wales applies its own Part P, with a wider notifiable list than England, and its own Part F with similar extract rates. Part H covers the new drainage route down from the loft.
