Once again, with the sink counter space being so tiny. Even with the Floating Shelves, there is just no easy way to keep toothbrushes, cups, toothpaste, razors, and other toiletry stuff around. I found this on Amazon and decided to give it a try.
It uses 3M tape to secure the mounting braket to the wall. Then the holder simply slides onto the mounting bracket. It is very easy to install. Just peel and stick. I waited for 2 days before putting the holder onto the mounting bracket and put the cups in place. It works great and we even had fun figuring out who gets which colored cup.
