I thought about it when we were putting together the plans. I have a lot of roller experience and don't need a rail to get started and I'm not concerned with falling off. However, I will be adding some sort of shelving on the side of it where I can place another fan, put my towel or phone. As of now, my idea will be to use some metal tubing and build off of that. Step 1 was to build the platform. The next phase will be applying the shelving unit. Just haven't fully designed it yet.
