Our house, when we bought it, had a high cistern toilet in a separate toilet 'room' next to the bathroom which DH (as an American city boy) found very odd. We eventually re-did the bathroom and put a new low level loo in the one room. The 'toilet room' now sans toilet is still known as the 'toilet room cupboard' and still has the backboard that the high cistern was attached to on the wall. I sort of wish we'd kept it now.
He was also horrified that a couple of houses we looked at still had their outside 'privy' intact but doubling as sheds and by carpeted bathrooms - also still around then! (1994) 😂
