I used drywall anchors to attach the soap dish to my shower/bathtub wall. Ceramic tiles on plasterboard wall. So I had to drill through the ceramic in the drywall. The hardest part was finding the right size drill bit. I started small and then progressed to a larger drill. I used the plastic anchors from that kit and the screws that came with the soap dish. The weight carried by the mounts is minimal. I ended up with a solid soap dish mount that looks nice. I'm happy with the result.
