How To Frame a Bathroom Mirror

Although most new mirrors already come with a frame, you might need to install one yourself if you have a frameless bathroom mirror.

The procedure is relatively easy, and you won’t need any advanced technical skills.

The first thing you need to do is measure your mirror. You have to be precise when measuring because you will find and install the right frame through accurate measurement.

Once you have the measurements, you can head to your local hardware store and buy your frame.

You can either buy unrefined pieces of wood and then shape them if you’re good at shaping wood, or you can purchase pre-made wooden bases, with or without caps, depending on your personal preferences. 

Then you need to apply the measurements and cut the wood to fit your mirror’s shape and size. Most mirrors are rectangular, so the best choice for you would be to cut the pieces under a 45° angle, preferably using a miter saw.

You can then modify the wood by applying color or staining it, but that is just your preference.

If you’re not much into aesthetics, you can leave it as it is. If you’re applying color – be sure to paint the whole piece so that you don’t have any leftovers that will ruin your final look. 

After you’re done, there are two ways you can approach this. You can add the pieces one by one or assemble them and then add the complete frame in one piece before applying it to the wall. 

You should start from the bottom piece if you’re going for the first option. Use a marker to carefully and precisely mark the future position of the frame and then apply glue (it’s best to use an S-shaped trail) to the wood or the mirror.

You will then, carefully, place the bottom piece of wood over the bottom side of your mirror, and – along with the glue – you can use liquid nails or a similar adhesive that dries quickly to position the lower frame.

Once you’re done, apply the other three pieces, and you’re done. Don’t forget to remove any glue sticking out, and if your joints are not completely aligned, you can use caulk to fix it. 

If you decide to use the frame as a single unit, the procedure is slightly different, although not drastically.

Once you’ve done all the measurements and are done with the preparations, you will have to place your pieces together on the floor or some other large, flat surface.

Then, you should glue the corners together using glue and fasten them with an L-bracket before letting them dry a bit.

When the construction is firm enough for you to move it, give it a test framing on the mirror to see if it fits and how you need to position it.

If it fits, mark the necessary spots with a marker and apply glue to stick the frame on. Once you’re done, hold the frame firmly until it stays on the mirror, and then let it dry before removing the brackets and cleaning your mirror.

Again, be careful to wipe off any glue that might have appeared beneath or between the frames. 

5 Things You’ll Need To Frame A Mirror

This section of the article will give you a list of the five most important things you’ll need to frame your bathroom mirror.


The frames are an essential part of your endeavor. You’ll usually buy wooden frames because they look more elegant.

Still, you can also use other materials like plastic or PVC, depending on your personal preferences.

As for the frames, if you’re a good carpenter, you can cut and prepare the frames yourself, but you have to have the right tools and the right skills.

If not, you can buy pre-made bases and then cut them by your measurements. You can also modify the wood by applying color or stains, but that is up to you. Just be sure your wood is completely dry before use so it doesn’t leave marks on the mirror. 


After obtaining your frames, this is the second most important thing on your list. If you’re going with wood, most adhesives (e.g., Loctite) will work perfectly, but if you’re using other materials, you might want to consult with the seller to find the best adhesive in such cases.

You will need an adhesive to connect the frames and an adhesive to hold the wood on the mirror, so be careful to find one that works well with the surface of a mirror.

You might also use liquid nails or similar adhesives to speed up the process a bit (since they’re good and dry up fast), especially if you’re assembling your frame piece by piece. 


You won’t need much here, but a precise tape measure, a level, and a saw will undoubtedly be of much use to you. The tape measure will be used to measure the side of your mirror and the wooden frames so that you know how much you need to cut off.

You’re going to need the level to make sure your frame is attached correctly and doesn’t look like an abstract painting, while the saw – your best option is a good miter saw that could cut angles – is used to cut and shape the frames according to your needs. 


If you have regular wood of the usual color, it might not fit with your bathroom walls and would look disproportionate. In such cases, you can always buy a can of wood color and use a Wooster brush or even a foam roller (depending on the size of your frames) to apply the color.

Be sure to apply it on both sides of the frames so that you don’t have any ugly-looking leftovers. Before you do anything, be sure to leave the paint to dry because your wood needs to be completely dry before use. 


When framing your mirror, you’ll probably end up with some non-aligned joints. Don’t worry, as that is entirely normal, and it happens to many people; you might be lucky to avoid it, but unless you have much experience with it, you’ll probably have some small misalignment.

Luckily for you, there is an easy way to fix it – caulk. Caulk is regularly used to seal and isolate joints, so it is handy and practical even with bathroom mirror frames.

These items can be found at your local Home Depot or Lowes.
