How to Frame a Builder-Grade Mirror

DIY your bathroom mirror frame and turn your builder-grade mirror into a beautiful design with less than $10 and 2 hours!

Happy day to you, dear friends! I spent yesterday morning out in the garage finishing a project that has been on the to-do list for years. The weather was gorgeous and my kids were occupying themselves – hallelujah!

I’ve had the supplies to finish this project for months now. I’ve recently gone on a mission to wrap up old projects that have fallen by the wayside. So, here’s project numero uno on that list!

Ok, so I know that this project is super basic and other DIY-ers have been doing this for years, but it’s such a good one that I HAD to do it for myself. And just for fun, I’ll share it with you. It’s so simple, though, that it seems silly to need a tutorial. But, I hope it helps you see just how easy it is!

I give you: how to frame a builder-grade mirror. SUCH an easy project, but makes a huge impact when it comes to customizing your home. When we gutted our old house, we put actual mirrors over our vanities in the bathrooms. I loved the look. And super don’t love the look of a plain, clipped-to-the-wall, builder-grade mirror.

Tools you need for a DIY Mirror Frame

• Interior Trim Molding (the length of the perimeter of your mirror)
• Miter Saw or Hand Saw and Miter Box
• Wood Glue
• Duck Tape or Painter’s Tape
• Spray Paint
• Chisel
• Hammer

How to Frame a Mirror

Step 1. Measure the perimeter of the mirror.

You’ll need to measure each edge of the mirror and allocate a couple more inches for each side if you want the frame to hang off the mirror edge at all. My mirror butted right up to the wall on the right and left sides, so the frame has to be placed completely on top of the mirror.

Step 2. Buy some Interior Trim Moulding from the hardware store.

I chose a simple style interior wood casing, but you could get as plain (think 2 x 4) or a fancy as you want. You just want to make sure the back of the moulding is flat.

Step 3. Measure each piece of wood to the desired length and cut the corners at a 45º angle on the miter saw.

I measured my mirror and marked off my cut lines on my boards. I cut them at 45° angle. If you don’t have a miter saw, then a hand saw and miter box will work just fine!

Step 4. Mark the spots on the frame where the clips are located on the mirror.

A big mental block for me was how to get the frame flush without removing the mirror clips. I decided to try to notch out the back of the boards.

I rubbed some blue chalk on the clips, the held the frame pieces on top of the mirror and the blue chalk rubbed off just enough for me to be able to see where they would hit.

Step 5. Notch out the frame where the clips will hit.

I marked off the spot on the back of the boards, and then scored a box using an exact knife.

Then I took my chisel and hammered out a space bigger than the size of the clips. It worked great! (I never thought I would need a chisel, but I’ve surprisingly used this one several projects!)

Step 6. Attach the corners of the frame.

Then I tried to figure out the best way to attach them to each other at the corners. I started off my trying liquid nails. I “clamped” the boards together with some duck tape and left them overnight. When I came back the next morning, all but one joint wasn’t stuck together. I think my liquid nails was old and I didn’t want to buy anything new for this project. Bummer.

So, then I tried to use my kreg jig and screw the joints together with pocket holes. No go there. The boards were too thin for that to work.

I finally went back to the drawing board and just used wood glue to glue the corners together and used duck tape to “clamp” them overnight. Worked like a charm!! Yay! (I had to sit some heavy objects on each corner to make sure they were flush when the glue dried.)

Step 7. Paint the frame the color of your choice.

I spray painted the back first (since are able to see the back side edge of the frame reflect in the mirror). Then flipped it and painted the front with white spray paint. I like this brand of spray paint the best!

I let it dry and then put it on the mirror. My mirror is the width of the bathroom walls, so I almost couldn’t get it in there because I made it just the same size as the mirror.

If yours is like this, I would recommend making your frame just slightly smaller in width than the walls. I had to force mine to go in. And since it had to be forced in there, I didn’t adhere it to the wall/mirror in any way. ☺️

I was planning on using command strips, though, since I don’t like to do anything permanent in case a future owner wanted to take it down. I’ve seen people use anything from hot glue to liquid nails to keep the frame up there.

Have you ever made a frame for your mirror? Is it on your to-do list?

(If not, it should be!)
