Working in Hamilton
In Hamilton we cover ML3; we also cover Motherwell, 2.2 miles away, and Blantyre.
Homes in and around Hamilton 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 Hamilton home, we work out how the shower will get its pressure before choosing a single fitting. If your Hamilton home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Most of Lanarkshire is supplied with soft water. If that holds for your street in Hamilton, 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 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
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.
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.
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.
