We have a cassette toilet / shower combo that I think I'm going to have to do some custom shower curtain job for. First time we used the camper, it was an unexpected trip so I just stopped at Dollar General and bought the first cheap shower curtain I saw, for privacy. I don't see how people use these things with nothing to hook the curtain to. It was all over the place. I'm thinking, when I find the one I want, I'm going to have to cut it to fit and then sew Velcro on in numerous places. I'm thinking about Velcro to hold it in place behind the toilet and along tub edges on other three sides. Has anyone else done this? Our pup came with the outdoor shower curtain, but the one for inside was disgusting and molded. I threw it away without even looking at it. They had it folded up in a plastic box. Gross.
