Build a Wood Mirror Frame with this Easy DIY

Sharing is caring!

Last Updated on December 7, 2023 by lindseymahoney

Bathroom renovations can be costly, so I was very excited to save some money by framing our bathroom mirror with this easy DIY!

This is a quick and easy project that we knocked out in a weekend and spent less than $50. The design for our new master bathroom included pale green walls with gray accents for a spa-like feel. I chose distressed wood to build the mirror frame and it was the perfect rustic touch!

Here is what the mirror looked like before:

1 | Measure the Mirror

Using a measuring tape, measure the length and width of the mirror. Local hardware stores typically have the largest selection with 8’0″ wooden boards.

If the length or width of your mirror is less than 8’0” then you are golden. If it is longer, you may have to special order the type of wood you want if it is not available.

2 | Purchase Materials

Chris found 4 pieces of distressed wood (similar) at our local Home Depot. The weathered finish was exactly what I wanted to offset all of the brand new finishes in the bathroom.

3 | Cut a Groove for Mirror Clips

The mirror is attached to the wall with mirror clips which prevents the wood from lying flat against the mirror. We borrowed our friend’s Dado blade set to cut a large groove on one side of each plank.

We cut a groove about 3/4 the size of the board, which was achieved by cutting multiple grooves next to each other. You can cut any groove size as long as it covers the mirror clip. The larger the gap, the more that the frame will cover the mirror.

4 | Measure and Cut Wood for Fram

Place one board against the side of the mirror until the edge of the groove hits the edge of the mirror. Use a marker and trace a line at the top and bottom of where the wood hits the mirror.

Move that same board to the bottom of the mirror and mark a line on both edges of the mirror. Repeat this process on the other sides of the mirror.

This will create the corners where the inside angle of the wood frame will sit. Measure the length from each inside corner to determine the length of each board at the inside 45 degree angle. Mark the inside corners of each board and cut a 45 degree angle using a table saw.

5 | Attach Wood Mirror Frame to the Wall

We attached the boards individually to the wall using a pin nailer.

When attaching each board, be sure to place the nail at the outside edge of the board to avoid hitting the mirror. We easily attached all four boards to create a rustic frame and it completely changed the look of our dated mirror!
