Working in Bonnyrigg
We cover every part of Bonnyrigg, including EH18, EH19 and EH24, and nearby Musselburgh (5.2 miles) and Penicuik (5.5 miles).
Being a smaller town does not change how we work in Bonnyrigg: free survey, written quote, one team. For a loft bathroom in a tank-fed Bonnyrigg home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Bonnyrigg around the roof line, so the shower sits where you can stand and the eaves become storage.
Water across much of the Lothians is soft. If that holds for your street in Bonnyrigg, 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 survey of the headroom across the room, with the usable height marked at each fitting position
- 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
- 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.
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 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.
