Which towns do we cover in County Down?
Most of County Down is supplied with soft water. If that holds for your street in Bangor, 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. If your Bangor loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
What the job includes
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- A survey of the headroom across the room, with the usable height marked at each fitting position
- 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
Decisions to make first
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.
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.
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.
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 Northern Ireland
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 Northern Ireland, building control covers the new drainage, any structural work to the floor and the ventilation, which is set out in Technical Booklet K. Wiring should be designed, tested and certified to BS 7671.
