We don`t have a hallway, so our under stairs cupboard is in the living room. It`s a great space, with shelves, but has turned into the biggest junk pile in Christendom! We have another, similar, cupboard, just slightly smaller, in the front bedroom, it goes over the stairs. I`d dearly love to have an extra toilet in there, seeing as our bathroom is downstairs, but the plumber who did our bathroom refit told us it would be horrendously expensive, as there`s no water supply to it. Where we do have a water supply, i.e. water pipes, is the small back bedroom, but that isn`t big enough to take space off for a toilet. It`s starting to be a real bind having to visit the toilet in the night, out of the bedroom, onto the stairlift to go down, then through the living room, kitchen and back lobby to the bathroom, then all the way back again, takes ages, and not much fun on cold nights!
