A bath cabinet mirror is an essential part of our daily lives. We rely on it for many tasks that we may not even think about, such as brushing our teeth and combing our hair. If the cabinet mirror becomes worn or it breaks, it's going to affect your daily routine. It's simple to replace a bathroom cabinet mirror with just a few common household tools.

Step 1 - For a Broken Mirror

If the mirror is broken, place masking tape over the surface in the shape of an “X” over the break. Allow it to extend several inches beyond the break. Glass that is shattered or has multiple fractures will require more work. It will be easier to use plastic wrap over the surface of the mirror, and tape the wrap down to the mirror. Doing so will prevent broken glass from falling when you make the repair.

Step 2 - Remove the Cabinet Door

Remove the door in order to access the mirror. Open the mirrored door, and use a screwdriver to remove the hinges. Depending on the size of the door, you may need an assistant to hold the door while you remove the hinges. Doing so will prevent damage. Remove the bottom hinge first, then work your way up. If the hinges are in good condition, set them aside to reuse later.

Step 3 - Remove the Mirror

Remove the framing. Most bath cabinet mirrors can be removed by locating the interior screws which hold the frame together. Remove them and set them aside. The back panel should come off easily, and the frame should come apart in several sections. Carefully remove the mirror and set it aside.

Step 4 - Measure for New Mirror

A lot of companies make their mirrors to a standard size. Check with the manufacturer to see if you can reorder a new mirror. If not, just measure the size of the old mirror and order a replacement to the specifications. If a custom order is out of your price range, just purchase a mirror slightly larger and have it cut to size. Most home improvement stores will cut glass and mirror panels for you for a small fee.

Step 5 - Install New Mirror

The new mirror will be installed in the same manner that you removed the old one. Ensure that the panel which holds the mirror in place is secure. You may want to consider using an adhesive in addition to the screws. Use adhesive to attach the mirror to the frame. Hang the mirrored door, starting with the top hinge and working your way down. Have a friend hold the cabinet door in place as you work.
