Toilet Paper Holder - Aluminium Double Roll Toilet Tissue Holder with Mobile Phone Shelf for Bathroom, 3M Self Adhesive No Drilling or Wall-Mounted with Screws, Rustproof Modern Style Black

You can find a stick on toilet paper holder on Amazon.Mine was coming loose, was in an uncomfortable spot and I couldn't move it because the pocket door is too close... So stuck the thing I got from Amazon on my glass shower the toilet is next to. It has the toilet paper roll plus a pack of babt wipes. It's not ungluing, even after many steamy showers. If you stick that to the wall, I'm afraid it will come off with a chunk of it if you ever want to move it, but plastering is super easy, so not a big deal. You can even get one that holds 2 rolls and there are several finsihes options.
