I think we want to do this for my elderly parents. Stairlift probably not an option as they live in a listed house, and both upstairs bathrooms have steps to access.
Interested in others' experiences. Did you just use a local builder/plumber or a wetroom/ disability specialist? I think we are going to need to move some partitions to make the bets use of the space available.
If you use an ordinary building company is it still VAT exempt?
