I have a pretty tiny shower/tub in my TT. It's like taking a shower in a phone booth.
I was looking into the Extend A Shower product to get enough extra room to at least keep the curtain from sticking to me, but after looking at it, I don't believe it would fit my shower. I have a 3 1/4 wall shower, with the quarter-wall serving as the side support for the sink and medicine cabinet, and the curtain has to cover the quarter-wall as well as the opening.
If I could put an extra joint in the Extend A Shower in precisely the right spot it might serve, but I'm pretty sure I can't. (Tell me if I'm wrong.)
Are there other products that people have successfully used to fit problem-shaped showers?
