We shared bath water in a no. 3 tub, maybe once a week, when some of my siblings and I stayed with my paternal grandparents. Our grandmother would heat the water on the stove and turn around and pour it into the tub, which was positioned near the back door in the kitchen.
The outhouse was about 200 yards from the backporch. We had to go down a trail in knee deep weeds to get to it. The seed ticks would jump from the weeds onto our bodies. When we returned to the house, our grandmother would take a soft bristled brush to us to get the little critters off. Oh, and the spiders in the one-holer - eeeek! It wasn't until the late 50s that they (finally) got indoor plumbing.
