For some unknown reason, our coach came with a set of towel rails inside the shower. Which makes no sense, since you’d have to remove the towels before using it.
So one of the first modifications we did after we got our coach was to remove the bars from those rails and flip the ends upside down, so they serve as hooks, and add another set of towel rails outside the shower.
Here’s a pic from years ago of the inverted ends of the rails (and soap dispensers, but we moved those elsewhere after I knocked them off a couple of times):
Our replacement is mounted above the toilet, next to the shower:
Much better!
