they never had any toilet back in the day. the same with prison's back in the day before toilets. they use buckets for the solid and liquid waste before the age of porcelain toilet.
Up until I was about 10, my grandparents lived on nice acreage in Arkansas. They didn't have running water or electricity, or anything but an outhouse for body functions, and a bowl on a stand for washing. When we needed to bathe, we heated water on the wood stove to pour into the wash boiler. In 1957 they got both running water in the house and electricity. They still preferred well water for drinking and bathing, and never gave up the wood stove until they sold the property in the late 60s.
Now admittedly that was a very long time ago - but while in the "last" century, it was still in the "modern era". I actually got a good chuckle out of the buckets etc. in this game.... nothing like that in most other games I've ever played!
