DIY Mirror Frame in Bathroom


Believe it or not, there’s a quick, easy, and affordable way to change the look of your bathroom, without replacing anything. Instead, you’re adding something – a simple DIY mirror frame around your already existing mirror.

Most “builder’s grade” homes today come with one large mirror in some such area. It works as mirror should and I can see my reflection – great. But it’s not the most attractive or decorative item, but it can be MUCH more appealing with a simple frame. Mind you, a frame can be added for any mirror but in particular, I’m going to show you how I put a frame on my large, 58×42 inch, mirror.


The “frame” that I picked out from Home Depot was actually very basic baseboard. It is 2 inches wide, and a ¼ inch thick. This can be the fun part because you can pick something as intricate as you’d like as there’s a ton of baseboard to select from.

Moving on, you can paint it whatever color you want but we painted ours Complex Gray by Behr Interior Semi-Gloss Enamel paint to match the vanity, which we also painted. You can find that post here. I recommend painting it first, as it’ll be much harder to after it’s up, but I don’t recommend painting it until after you make ALL of your cuts.

I used a Wooster Angled Brush to I apply 2 coats of paint to the front surface of the mirror frame. I let the paint dry a couple hours in between coats. I also, applied 1 coat of paint to the back of the mirror because you may see some of the back in the reflection of the mirror. Make sure to save the brush in an airtight plastic bag, so you can reuse the brush in case you have to touch up any areas after removing the painter’s tape.

STEP 1: Cuts

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.

STEP 2: Notches

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. But if the frame has to be flush against the mirror, how do I get around this?

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 to the long frame pieces up to the mirror and 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. You will need some wiggle room with these.

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.

That is as complex as it gets. I had to make sure it was deep enough that the frame was flush against the mirror. It took me a couple tries as I was careful that I didn’t go too deep. Make sure you dry fit your frame to make sure everything aligns before adhering it.

STEP 3: Adhering the Frame

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 that, I did the same thing for the two side pieces and then the top piece last.

We recently replaced the outdated Hollywood glam light fixture with an in expensive brushed nickel fixture. Come back soon for an update on how to install a light fixture.

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. Comment below with any questions.
