My grandma (alive today) grew up with no indoor plumbing in the United States. They had to use an outhouse. > In 1940 nearly half of houses lacked hot piped water, a bathtub or shower, or a flush toilet. Over a third of houses didn't have a flush toilet. https://www.aceee.org/files/proceedings/2004/data/papers/SS04_Panel1_Paper17.pdf https://www.aceee.org/files/proceedings/2004/data/papers/SS0...
