Towel Rack?

I'm looking for a brushed stainless steel bath towel rack to hang inside of my shower so that we can hang our wet towels without them being seen. We have a plastic like tub so I can't screw anything into it. I'm looking for a suction kind or one with the tape behind it but cant seem to find it. I can only find washcloth ones. Has anyone seen these anywhere and if so, where? And ideas of what else I can do to hang one?
