What does a loft bathroom cost in Dunoon?
Guide price in Dunoon: £6,200–£12,500 including VAT, depending on the room and what you choose. Prices in Scotland run at about 4% below the national guide, mainly because of labour rates. Travel and delivery to islands and remote areas are priced on your quote. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Dunoon
We cover every part of Dunoon, including PA23, and nearby Greenock (6.4 miles) and Helensburgh (8.7 miles). Because Dunoon is further afield, we arrange survey visits in batches; tell us your timescale and we will confirm a date before you commit to anything.
Dunoon gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For a loft bathroom in a tank-fed Dunoon home, we work out how the shower will get its pressure before choosing a single fitting. If your Dunoon loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Water across much of Argyll and Bute is soft. If that holds for your street in Dunoon, 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 drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- 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.
