We have a stand thingy that holds 3 or 4 rolls of paper in a stack. For our Rockwood 8319SS, most of the time it sits in front of the shower door. But no problem to just pick it up and move it when using the shower. When we're moving it goes inside the cupboard.
We mounted ours on the inside of the cabinet door. We purchased a better model at Lowes that allowed us to use command tape. No screws or damage to the door. That way if you don't like there, it's easy to move.
