Working in Irvine
As well as Irvine itself (KA11 and KA12), we survey in Kilwinning, Kilmarnock and Ayr.
In Irvine, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Irvine home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. For a loft bathroom in a tank-fed Irvine home, we work out how the shower will get its pressure before choosing a single fitting.
Most of Ayrshire is supplied with soft water. If that holds for your street in Irvine, 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 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
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.
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 Scotland
In Scotland, forming a new bathroom in the loft or altering the drainage may need a building warrant. The Technical Handbook uses 15 litres per second extract for a bathroom, and water fittings are covered by the Scottish Water Byelaws 2014.
