I was skeptical at first if you can mount a hair dryer holder without drilling and with adhesive. But it is for 1 year in use and adheres to the tile and does not give up. Installation is super easy, 2 holes on the bracket are available. In one of the adhesive is injected into it and until the adhesive is pending from the 2nd hole. Fix for a day with a tape and even the hair dryer holder is criticized. Highly recommended.
