We HAD a shower, but I don't remember anyone ever using it. We had a shallow well that would dry whenever it felt the urge. We kids just took baths in the same water. Just add some hot as it got cold. I know unheard of today, but back then...things were different.
I also remember taking a bath in a washtub in the kitchen as my father, grandfather, uncles and such worked on the house as they got the time.
I remember using an outhouse too, but I don't know for how long. Even after the plumbing got installed, the kitchen and bathroom sinks just drained out into the woods. The environment hadn't been invented then, and it reduced the load on the septic tank.
We had an old well pump and tank that was outside the well in a "pumphouse." When it got dry, we'd cut the pump off, then as needed, we'd go out and "start the pump." Usually that involved flipping on the electric switch, then taking a stick stored there, and pushing against the pump flywheel to get a prime (I didn't know why when I was a kid. I just did it because that what you had to do.) After a few pushes, the pump would "CLICK", then start, pump until the tank was pressurized, then cut off. Then we'd turn the switch off and wait until the next time my mother called out "go start the pump."
