Our little sink was getting crowded, so I designed a wall mounted holder to keep our toothbrushes out of the way. I'm not about to drill holes in our landlord's ceramic tile, so I fixed them to the wall with 3M double sided tape (best stuff ever!). If you so desired, you could easily add a hole to mount this using screws.

This fits the "PowerUp model" of electric toothbrush from Philips (the one that runs on AA batteries).
