Whenever I searched for toilets/restrooms/.... in the middle ages I only found sketches or engravings about either clerics (probably curches) or about rooms on the side of the walls of castles.
But never did I find anything about either public toilets or other toilets/restrooms that commoners / peasants used / had available to them in the middle ages.
So my question would be here: Did a commoner have any restroom/toilet facility (public or otherwise) available to him on the countryside (small towns) or large cities?
