Materials Needed for Wooden Mirror: You may already have some of these in your garage

Step 1: Purchase frameless mirror

You can choose the specific size you want from Home Depot’s website, but I am basing my example off of the 36 in. W x 60 in. H frameless rectangular bathroom mirror.

Step 2: Buy OSB board and cut to size

The next step is optional, but it makes the base of the mirror stronger for adding a frame. So, you will purchase a large piece of OSB board, and it will be larger than your mirror. Then, you will cut the OSB board down to leave enough room around the edge for your frame to be added onto.

Step 3: Glue mirror to the OSB board

Use Wood Gorilla Glue to secure your mirror onto the OSB board. Make sure you center it properly!

Step 4: Buy the wood and build your frame

For the wooden mirror you will need to create your wooden frame. You can use any type of wood and any thickness. For the cheapest frame, buy three (3) 6ft x 5.5 in. pieces of common board, pine. This is where you can decide how much you truly want to spend on your mirror. You may need a friend or family member to help with this part, and if you need to rent any tools check out Home Depot’s Tool Rental.

Each board will need to be cut at a 45 degree angle to line up at all corners.  Start with one of the boards on the longer sides.  Since we didn’t have a miter saw, we measured the width of the board at 5.5 inches.  Then we measured down the board, and marked it at 5.5 inches.  We then used a straight edge to draw a line through the corner of the board.  We had to think way back to good ol’ geometry class and reference a right triangle.  We knew if sides a and b were the same length, it would ensure that angles A and B would be 45 degrees.

Cut your wood at 45 degree angles on the shorter side to line up with with the longer sides while measuring the width of the mirror.  Then we cut the other shorter side with the exact same measurements.  Finally, cut the bottoms off on the longer sides to match the length of their mirror.

Once you’ve got all the boards cut, before attaching them, I found it easiest to sand the wood in this step.  You’ll want to make sure that you get the tops and all sides to make sure they aren’t any sharp edges poking out.

You’re finally ready to build your wooden mirror frame!  You’ll want a friend to help you during this step.  Add a generous strip of Liquid Nails glue to the edge of each side one at a time.  After you glue the side, immediately use the staple gun on the back side of the frame to pop in about 10 staples. This can get a little messy, so you will want to wipe off the staple gun will you do this so it doesn’t get clogged up.  Once you’ve finished all sides, you will want to add weight to all four corners (we used paint cans) and let it dry for 24 hours.

Step 5: Stain your wooden frame

Last step is to stain your frame! You can choose any color stain, I went with a darker stain to contrast my light walls. You can use any rag to stain and ensure you wipe away any access material.

There you have it! Share with your friends and family if they too are looking for a cheaper alternative to a 6ft wooden mirror.
