Building a better toothbrush holder

Photo 1: Glue the magnets

Mark the position of the magnets and glue them on the mounting strip, orienting the magnets so they attract each other.

Photo 2: Mount the holder

Glue the mounting strip to the wall with Super Glue, hot-melt glue or silicone caulk.

The problem:
Battery-powered toothbrushes don’t fit in toothbrush holders and end up lying on a wet, messy countertop.

The solution:
Mount neodymium (“rare earth”) magnets on a Corian mounting strip with Super Glue. Glue the strip to the wall with Super Glue or clear silicone caulk.

Tools and materials:
To make the mounting strip, cut a Corian threshold (available at tile stores and home centers) with a miter saw or jigsaw. Neodymium magnets are available from internet suppliers (search “neodymium magnets”). We used 1/2-in. x 2-in. x 1/8-in. magnets, grade N42 (the higher the grade, the stronger the magnet). You can double them up if you need more holding power.

Note:
Neodymium magnets are incredibly strong but break if handled roughly. Order several more than you need—shipping is expensive. Also, don’t handle neodymium magnets if you wear a pacemaker, and never leave them next to your computer or credit card. For more safety information, search “neodymium magnet safety” on the internet.

Make Any Toothbrush Stick

Battery-powered toothbrushes have hidden steel parts that stick to magnets. Mount standard toothbrushes by adding a tiny screw or metal washer to the back.
