Working in Paisley
We work right across Paisley — PA1, PA2 and PA3 — and in neighbouring Barrhead and Renfrew.
Across a large town like Paisley, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. If your Paisley loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. If your Paisley house has a combi boiler, a loft shower can usually run on mains pressure without a pump.
Water across much of Renfrewshire and Inverclyde is soft. If that holds for your street in Paisley, 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A survey of the headroom across the room, with the usable height marked at each fitting position
- A check of the floor joists where a bath or large shower tray will sit
- 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.
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 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.
