Mirrors are a staple of interior design, and for a good reason. They enhance lighting and make areas of the home feel more spacious.

In the bathroom, they serve another purpose, helping us see what we’re doing as we navigate our wake-up rituals.

In this lesson, we’ll teach you how to install a bathroom wall mirror so you have plenty of reflective power throughout the day!

Let’s get started on our DIY wall mirror installation project.

Let's Make It


  • Measuring tape
  • Pencil
  • Stud finder
  • Drill
  • Caulking gun
  • Putty knife
  • Level


  • Frameless wall mirror
  • Silicone
  • 4 Mirror clips/brackets/anchors
  • 8 Construction screws

How Mirror Clips Work

Four mirror clips will hold the mirror in place at the top and bottom of the vanity. The clips are also called mirror hanging brackets or anchors.

The larger, flat side of the mirror clips attaches to the wall, while the channel and lip hold the mirror secure.

In addition to the clips, the mirror will also be fastened to the wall with glue/silicone. This establishes a multi-faceted system to hold the mirror in place. We always recommend using both glue and mounting brackets for bathroom mirrors.

Each clip has four holes. The circular holes are for permanent screw locations. These are used when installing the brackets at the bottom of the hanging mirror.

The elongated holes are used for the top. They allow you to fasten the screws in the slot and then drop them down into the final position during the DIY wall mirror install. This way, the bracket can be affixed to the wall, the mirror installed, and the clip slid into place.

How To Hang And Mount A Frameless Bathroom Vanity Mirror On A Wall



Construction Coach

Measure the length and width of the area where you’d like to install a frameless bathroom mirror. 

Info: If there is a row of backsplash above your bathroom sink, the frameless vanity mirror needs to be above the tiles.

Once you have recorded the dimensions, send them off to the glass cutting company to have your custom mirror fabricated. 

The mirror thickness we used for this project is 5mm (about 3/16 of an inch). Frameless bathroom vanity mirrors are most commonly available in 1/8, 3/16, and 1/4 inch thicknesses.

Info: Custom cut frameless bathroom mirrors typically cost anywhere between $6-20 per square foot. However, this price includes professional mirror installation. Since we’re teaching you how to hang s frameless mirror on a wall yourself, the material costs will be even cheaper!

Tip: You can also buy standardized wall mirrors for DIY projects at many home improvement stores. Having said, chances are they won’t fit your specific space exactly. But, if you’re looking for a rectangular or square bathroom mirror, you might be able to find something suitable at a hardware store at a lower price point.


Locate Studs

Construction Coach

Use a stud finder to make the positions of the studs in the area behind the mirror.

The frameless bathroom mirror mounting clips should always be fastened to a stud for adequate support.

You need to find two studs to hold the bottom brackets of the vanity mirror.

Determine which studs will hold the weight of the hanging bathroom mirror evenly.

Make sure there is enough room for the clip to hold a complete section of the mirror. If the stud you plan on using utilizes only half the clip because it’s where the edge of the mirror will be, use a different stud.

Use a pencil to mark the center location of the studs.


Mount Bottom Mirror Clips

Construction Coach

With the studs located, fasten the bottom mirror clips into them with a drill and construction screws.

Use the circular (not elongated) holes in the clips to screw in the bottom brackets. The lip of the bracket needs to be at the bottom as it will hold the mirror from below.

Tip: When working off a backsplash or countertop ledge install the lower section of the mirror clips flush against the edge of tile or countertop material. If you are installing the mirror without a backsplash or countertop edge, use a tape measure and level to ensure the brackets are straight.


Mark Top Of Frameless Bathroom Mirror

Construction Coach

Bring the frameless mirror into the bathroom and place it onto the bottom brackets.

Take a pencil and mark the wall where the top edge of the mirror is located.

Info: The line will help determine where the top clips of the mirror will need to be fastened for the installation

Try to make the line above where the bottom clips are fastened.

Info: The top clips will also need to be secured to the studs, and they will also need to be aligned with the bottom clips for a better finish.

After marking the top edge, remove the mirror.

Tip: While dry-fitting the mirror, use a level to double-check if it’s straight. If not, the bottom clips may need some adjustment. It’s much better to make alterations now before the mirror is glued!


Mount Top Mirror Clips

Construction Coach

Use a level to determine where the top brackets must be placed in order to be even with the bottom brackets. Mark these locations on the line for the top edge of the mirror.

Use a stud finder to ensure both these locations has a stud behind them.

For the top brackets, the lip of the mirror bracket needs to be facing upwards.

Use a drill and construction screws to fasten the mirror clip to the stud, using the elongated holes on the bracket. Use a level to make sure the mirror clips are straight.

Fasten the screws into the bottom of the elongated holes so that the clips can slide downwards. Sliding the clip down will lock the mirror into place.

Slide the clip down fully. Make sure it is just slightly below the top edge of the mirror, according to the line made earlier. This ensures the clip will be firmly in place.

Now that the placement looks good slide the clip back into the up position. It needs to be up so that the vanity mirror can fit into place.

Repeat this installation process for both top mirror clips.


Glue Frameless Bathroom Mirror

Construction Coach

Info: Glue/silicone also needs to be utilized in combination with the mounting mirror clips. If the glue ever lets go, the brackets will hold the mirror and vice versa if the clips should fail. For hanging mirror installation, always use this double fastening system. This way, you know you’re covered, and your mirror will stay in place. Mirrors with only one system call potentially fall — especially during cleaning. 

Use a caulking gun to apply silicone to the back of the mirror.

Apply the silicone glue in roughly one-foot diameter half circles that are evenly spaced apart.

Info: Half circles are used to allow air to escape. This method creates better adhesion between the wall and the hanging mirror.


Mirror Installation

Construction Coach

With the silicone on the back of the mirror, align the mirror on the bottom clips and pop it into place.

Press firmly on the center of all the locations where silicone was applied to make sure the glue sticks to the wall.


Fasten Top Mirror Clips

Construction Coach

It’s now time for the final step of the DIY wall mirror installation project. 

Use a putty knife to gently get behind the top brackets so they can easily slide down into the locked position over the mirror.

Push the clips down, so the metal clips are snug against the mirror.

Tip: For added protection, add a dab of silicone across the top of the slidable mirror clips. Doing this will prevent the clip from moving accidentally, which could potentially happen when cleaning the mirror.
