What does a loft bathroom cost in Dumfries?
For Dumfries, our guide range for a loft bathroom is £6,200 to £12,500 including VAT. Prices in Scotland run at about 4% below the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Dumfries
We work right across Dumfries — DG1 and DG2 — and in neighbouring Locharbriggs and Annan.
Homes in and around Dumfries vary, so we look at the floor, the walls and the water system before we price anything. If your Dumfries loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself. For a loft bathroom in a tank-fed Dumfries home, we work out how the shower will get its pressure before choosing a single fitting.
Water across much of Dumfries and Galloway is soft. If that holds for your street in Dumfries, 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 drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A check of the floor joists where a bath or large shower tray will sit
Decisions to make first
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.
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.
