Framing a large bathroom mirror is a quick, easy, and affordable way to dramatically update your bathroom without replacing anything.

Bathroom Mirror Trim

Buying new a bathroom mirror isn’t as easy you would think because it is not simple task to take down a large builder grade mirror.

Builder grade mirrors have several clips and heavy duty adhesive holding them in place.

These bathroom mirrors are practically stuck on a wall forever after the adhesive is applied.

You can get the large mirror off with a few tricks, but there is no guarantee that it wont shatter all over the place.

7 Years of Bad Luck – Avoid This and Add Mirror Trim Instead

I remember hearing this as a kid if you shatter a mirror. Is this even true?!

I don’t want to find out, so my large bathroom mirror is not coming down and I am adding a frame to it instead.

A DIY mirror frame can be customized for any size builder grade bathroom mirror.

I’m going to show you how to add mirror trim and how to update decorative mirror with scrap wood.

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.

Best Bathroom Mirror Trim and Vanity Paint

Both the diy mirror frame and bathroom vanity were painted with Behr Interior Semi-Gloss Enamel and tinted with Sherwin Williams paint colors.

I have used this Behr paint on several pieces of furniture, cabinets, this vanity, and more. This is the best paint to use for this project, especially because it can withstand moisture and mildew.

The bathroom mirror frame was painted in the color Green Black by Sherwin Williams and the bathroom vanity was painting in Mountain Road by Sherwin Williams.

How to Cut the Wood for Large Bathroom 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.

Notching the DIY 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.

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 Bathroom 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 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.

Apply Loctite to back of each frame piece in a wave pattern as seen below.

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.

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

Repainting Bathroom Vanity and DIY Mirror Frame

I just didn’t love how this gray came out, so after a few years I finally decided to repaint it.

The mirror frame and painted vanity still looked great, but just need a quick sand to repaint them.
