Working in Ballymena
We work right across Ballymena — BT42, BT43 and BT44 — and in neighbouring Antrim and Magherafelt.
Homes in and around Ballymena vary, so we look at the floor, the walls and the water system before we price anything. For a loft bathroom in a tank-fed Ballymena home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Ballymena around the roof line, so the shower sits where you can stand and the eaves become storage.
Most of County Antrim is supplied with soft water. If that holds for your street in Ballymena, 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.
What the job includes
- A check of the floor joists where a bath or large shower tray will sit
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- 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
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.
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 Northern Ireland
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.
