Disappearing Mother Trick

When people say they can't take a shower while also taking care of a baby, I'm afraid I don't get that. I've been putting H. in a bouncy seat in the bathroom with me and things seems to go okay. Until, of course, she becomes upset because I've disappeared behind the shower curtain for long enough that she's sure I'm gone forever. So I'm thinking of getting a clear shower curtain, so she can see that I'm still there. I think just a clear liner would do, or else something a little more interesting like the one above. Has anyone tried this? Do you think it will work?
