We use a tp holder that sits on the floor. As far as towel bars, you might could use some 3M two sided tape to stick the bars on with. I believe they do make an "industrial strength" tape. I bought my two shelf towel rack at Target, but it is screwed into the wall. My control panel is not behind it. Would post pics but my unit is still in storage.
