How To Mount Gym Mirrors The Right Way: All Types

Don’t ruin your expensive gym mirror by mounting it the wrong way. Nobody wants to get to the gym and see the mirror on the floor in a thousand pieces. Proper mounting is safer and gives you peace of mind. 

When mounting gym mirrors, consider the surface’s weight-bearing capacity and use appropriate mounting hardware. For frameless mirrors using J-channels is the best choice. Mirror tiles should be installed on a clean and level surface using adhesive, with careful attention to alignment.

Below you can read some general guidelines for mounting gym mirrors and then some specific tips for the different types of gym mirrors.

Besides those (important) points, what are some things to keep in mind when mounting workout mirrors? Here are some general guidelines that go for all types of mirrors. Below you can also find some more specific tips for the different types of popular workout mirrors. 

Here are some general guidelines for mounting gym mirrors:


First, make sure the surface (wall) the gym mirror is going to be mounted on can handle the weight. In most cases, this won’t be an issue but on drywall for example, you’ll have to make sure to mount most of the load on the studs. 

Glass gym mirrors can get quite heavy, especially the very large ones. Checking if your wall can handle it and where to put the load can help prevent a lot of cleaning and buying a new mirror later on. 

Mounting Hardware 

Use appropriate mounting hardware designed for gym mirrors. Heavy-duty anchors, screws, or mirror clips are commonly used. Ensure the chosen hardware is capable of securely holding the weight of the mirror. Follow the manufacturer’s instructions for the specific mounting hardware you are using.

Most proper gym mirrors will come with mounting hardware but some cheaper ones might not. Don’t skimp on cheap mounting kits. Those might work for smaller mirrors but not for large, heavy gym mirrors. 


 Use a level to ensure the mirror is mounted straight and level. This is important for both functionality and aesthetics. Adjust the mounting hardware as needed to achieve a level position.

You want the mirror to be exactly 90 degrees perpendicular to the floor. If it isn’t, you get weird visual distortions. If one of the sides of the mirror is closer to you, that side of your body will look bigger. E.g. if the top of the mirror is closer to you, your upper body will look bigger. That might be fun but doesn’t give you proper visual feedback. 


 Take necessary precautions to ensure the mirror is securely mounted. Double-check the stability of the mirror after installation by gently pushing or shaking it. Ensure it doesn’t wobble or come loose. If there are any concerns about stability, reinforce the mounting or seek professional assistance.

When lifting (and especially dropping) heavy weights, this sends vibrations through the whole structure. Not a big deal in most cases but there should be no chance the mirror falls off because of those vibrations over time. 

Other Considerations 

Avoid mounting the mirror in a location where it may be exposed to excessive moisture or direct sunlight, as these factors can affect the longevity and quality of the mirror. Additionally, consider the positioning of doors or windows that could cause unwanted reflections or interfere with visibility. 

How to Mount Frameless Gym Mirrors

The best gym mirrors are large, frameless mirrors made from tempered glass. Here’s what you need to know about mounting them. 

1. Determine the Mounting Method

There are a few common methods for mounting frameless mirrors. The choice depends on the size and weight of the mirror, as well as the type of wall you’re mounting it on. The options include adhesive mounting, mirror clips, J-channels, or a combination of these methods. For heavy mirrors, as you use in a gym, J-channels are the best option for heavy gym mirrors. For frameless mirror tiles, see below. 

2. Prepare the Wall 

Ensure that the wall surface is clean, dry, and free from any debris or dust. If necessary, use a stud finder to locate and mark the studs in the wall. Mounting the mirror on studs provides better support and stability.

3. Mounting

J-channels are metal or plastic channels that provide a secure ledge for the bottom and sides of the mirror. 

  • Measure and cut the J-channels to match the dimensions of the mirror. 
  • Attach the J-channels to the wall using screws or nails, making sure they are level and properly aligned. 
  • Carefully place the mirror into the J-channels, ensuring a snug fit.

4. Check Stability

 After mounting the mirror, check its stability by gently pushing or shaking it. Ensure it is securely held in place and doesn’t wobble or come loose. Make any necessary adjustments or reinforcements if needed.

How To Mount Mirror Tiles In a Gym

When building a gym mirror from tiles, it’s better to use adhesive. This is because using clips or j-channels will create large gaps between the tiles. These gaps obviously don’t reflect anything so you’re getting a very segmented reflection which is no good for gym mirrors.

Most tiles come with adhesive backing which makes the process easy but also provides a few challenges. 

1. Level Surface

The key thing to get right when using mirror tiles is a very flat wall. If one tile is at a slightly different angle because the wall isn’t flat or there is a little bit of debris stuck under it, that tile will reflect light in a different direction. That means you’re not seeing a smooth, realistic reflection but more something from a fun fair. 

2. The Right Surface

The surface of the wall is also important. Mirror tiles aren’t super heavy but they aren’t going to stick on peeling wallpaper for example. You want a solid surface that can’t come off under the weight of the mirrors. Also, these tiles often don’t stick on wood very well. 

3. Prepare the Surface 

Ensure that the surface where you’ll be mounting the mirror tiles is clean, dry, and free from dust or debris. Use a mild cleaner and a cloth to wipe the surface and remove any dirt or grease. Let it dry completely before proceeding.

Adhesives will stick to dirt or grease but the dirt and grease don’t stick to the wall very well, which means the tiles will come right back off if there is too much dirt and grime under them. 

4. Measure and Plan

Determine the layout and position of the mirror tiles on the wall. Measure and mark the desired locations where each tile will be placed. Use a level to ensure that the lines are straight and the tiles will be properly aligned.

Use a pencil to mark the final outline of the mirror on the wall. After drawing check if all the lines are level and if the corners are 90 degrees. 

The old saying goes: measure twice, cut once. While there’s nothing to cut in this case, the tiles are very hard to get off once they’re on the wall so correcting a mistake is not so easy.

5. Install the Mirror Tiles 

Press each mirror tile firmly onto the wall, aligning it with the marked positions. Apply even pressure to ensure good adhesion.

The easiest is to start at the top left. Place the first tile in the corner of your outline.  Make very sure the first tile is perfectly level and square. This is the tile that all the other ones are going to be tight against so if the first one is crooked, the whole mirror is going to be that way. 

A single tile being slightly off isn’t that bad. 20 tiles being off is going to be very noticeable and irritating. 

After you get the first one perfect, move on to the two tiles to the right of the first one. Push them right up against the first and second tiles to get the smallest seam possible. After installing, check if there is a straight line over the top and bottom of the seam of all tiles. If not, correct it while you still can. 

If you got a straight line, you can now fill in the rest of the outline a bit easier since you can use the top row as a guide. 

6. Allow the Adhesive to Cure

Follow the manufacturer’s instructions regarding the curing time for the adhesive. It typically takes at least 24 hours for the adhesive to fully set and bond the mirror tiles to the wall. Avoid disturbing or putting any pressure on the tiles during this time.

If you see any distortions in the image by a misaligned tile, you can try to correct it now. Later on, it’s going to be impossible.
