I am 48...my grandparents had an outhouse....I just shudder that I am part of the "old timers" history...YUP not only used an out house...but my grandparents would boil water and set up the "tub" for a good old fashion bath...galvanized tub that is...
Our shallow well water wasn't really very good, So we relied on a cistern.
My parents never had an outhouse, but my grandparents did, and I married a man in the 1970s whose family still used one. Our generation is probably one of the last to have that experience.
