Toothbrush holders are too small for most toothbrushes, but this DIY wall-mounted neodymium magnet holder can handle any size, from large battery-powered to unusual curved designs.

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.

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.
