This old house only has one bathroom so an alternative will be nice. It probably had an outhouse when it was first built in the 50’s. I’m not above putting another one in the yard. LOL I have used many of them.
Back before I hurt my ankle, I was riding a mountain bike 20-30 miles back in the woods and hills. I carried a 5-gal bucket in my truck. I put a seat on it and put a small trash bag with kitty litter in it. My truck had a back seat area and the bucket sat there when I rode. That was my way of not having to use a public outhouse. Yuck!
