No indoor plumbing or modern toilet? Hot and cold running water is mandatory to my way of life! Bathing, hand washing, clean clothes, clean dishes and flat ware – all of this requires water in easy supply.
You know that hypothetical question of “if you could Time Travel, when would you go to?”. My stipulation is only time periods of indoor hot and cold water!
But- even today, everyday, I see folk who don’t have a safe and private place to deficate or pee. Take a walk around your neighborhood and see if you can find a public toilet or shower. I’m betting you are more likely to find signs like this.
