Have no experience of these wash basins above the loo concept, but I have heard of them. I do have a smallish downstairs loo, but with a very small sink. Some people have mentioned having an outward opening door, but how about one of those concertina doors to give you a bit more room in there and then you may be able to accommodate a small wash basin?
A super-quick, easy dinner for Gdcs when you’ve all been out all day and they’re ‘starving’….
