Before Painting Vanity and Framing Mirror

DIY Mirror Frame for Builder Grade Mirror

The frame that I picked out for my builder grade mirror is very basic baseboard.

This mirror frame measures 2 inches wide, and a ¼ inch thick.

The bathroom mirror frame can be painted or stained in color you any color that matches the bathroom in your home.

I decided to paint my mirror frame the same color as the bathroom vanity that I painted for an easy bathroom update.

Both the mirror frame and bathroom vanity were painted the color Complex Gray by Behr Interior Semi-Gloss Enamel.

DIY Mirror Frame – Shopping Checklist

How to Cut the Wood for Large Mirror Frame

For the large master bathroom mirror, I cut the two short sides on 45 degree angles at 42 inches long each.

The long sides were also cut at 45 degrees (both sides put together make a perfect 90 degree angle – High school for the win) and they were each cut at 59 inches.

I know what you’re thinking: “But you said your mirror was only 58 inches long.

Do you even math, bro”? …well, it’s always better to have more than less and the overlap certainly doesn’t hurt because I wanted to make sure it covered the entire mirror.

How to Cut the Wood for the Half Bathroom

I used a decorative mirror for the half bathroom that I had laying in my basement.

The frame on the decorative mirror did not go with my half bathroom, so I removed the plastic frame and made a stick on frame for bathroom mirrors.

Then I measure the mirror and cut the pieces of wood to length instead of cutting the wood at a 45 degree angle.

I was going for a rustic look in this half bathroom, so I did not want it to look perfect.

Once I made all the cuts for this mirror, I stained this mirror with 2 different stains.

Notching the Mirror Frame

Now then, after your pieces are cut, you might run into the issue of the mounts holding the mirror up.

There are probably 4 of them – 2 on the top and 2 on the bottom.

Those are holding the mirror in place so it’s important that I didn’t remove them unless I wanted the mirror to explode all over my bathroom.

DIY Bathroom Mirror Frame for builder grade mirror

This part can be a bit tricky and you might know a better way of doing this than me.

The first step is to hold the long frame pieces up to the mirror then draw an outline on the wood where the clips will align on the frame.

Definitely make the outline bigger because, it gives you some play so the frame actually aligns.

Cutting Around Mirror Clips

Now you’ll want to chisel out a gap in the frame where you traced your clips.

I used a multi tool to carefully make small etches in the wood, then made etches in the other direction so it was like a tiny checker board.

After that, I just “dug it out” with a chisel and hammer, again careful to not puncture the front side.

Then I had to make sure it was deep enough that the frame was flush against the mirror.

Make sure you dry fit your frame to make sure everything aligns before adhering it.

How to Paint or Stain a DIY Bathroom Mirror Frame

After the frame has been cut to size, give the frame a light sanding then wipe down to begin painting.

I recommend painting or staining the mirror frame after all of the cuts have been made.

Once I finished sanding the wood for the half bathroom, I stained the wood with a light gray stain.

Then I stained the wood again with a darker brown stain for a rustic finish.

By the way if you are looking to update your vanity here are tips and tricks to paint your vanity.

Behr Interior Semi- Gloss Enamel

If you want to learn more about this paint, and why I chose to use this view my post here.

I used an Angled Brush to paint the front surface and the back surface of the mirror frame.

If you are painting a larger mirror frame, you could also use a high density foam paint roller to smooth out brush strokes.

Before applying the 2nd coat of paint, I let the mirror frame dry for a couple hours in between coats of paint.

I also, applied 1 thin coat of paint to the back of the mirror frame because you will see a some of the back in the reflection of the mirror.

Make sure to save the Wooster Angled brush in an airtight plastic bag, so you can reuse the brush again.

You might need to touch up a few areas after removing the painter’s tape.

Adhering the DIY Mirror Frame to Builder Grade Mirror

To adhere it to the mirror, I used Loctite – Mirror, Marble, and Granite Adhesive.

I put some on the back of each frame piece in a wave pattern, to make sure that some of the adhesive will make contact with the mirror.

I started with the bottom piece and once it was in place, pressed firmly.

I used painters tape to hold it in place until it dried (48 hours at least).

After removing the painters taper, touch up paint or stain on the bathroom mirror frame.

If you don’t want to spend a ton of time and money to renovate your your bathroom, a painted vanity and mirror frame can make a big difference!

I have painted every room in my home, painted my kitchen cabinets, several pieces of furniture, and more.

If you previously painted your vanity and just don’t love it, here are tips to repaint your vanity or cabinets.

Before this project we decided to add new tile to the floor in our guest bathroom. Take a look at how our bathroom reno on a budget turned out.

Adhering the Frame for the Half Bathroom

I followed all of the same steps as above to adhere the DIY bathroom frame for my half bathroom.

The only difference is that I removed the original oval mirror and I did not cut the wood at 45 degrees.

This was an easy way to take the bathroom up a notch with minimal cost and minimal work.

It doesn’t always have to be a massive reno project to add value to your home! It’s the simple detail that can make the difference sometimes.

  13. Hi! I am new to DIY but am I missing how the side of the mirror is flush to the wall when the frame is glued to the mirror? I don’t understand how the frame is flat to the wall and also over the mirror. Does that make sense?

    1. Hi Jess!
      Thanks for reaching out, so the frame does not actually rest against the wall. The frame goes directly over the mirror, and matches up edge to edge with the mirror. I just took a close up photo of the frame to show how the frame lays over top of the mirror. Scroll through the post to get a better idea of what it looks like. Hope this helps, let me know if you have any other questions!
