Mirrors are usually heavy. Bathroom mirrors are quite large, sometimes even taking up entire walls. Install the mirrors to the walls using brackets or heavy duty glue. Use these steps to move your mirror around in your bathroom.
Steps

Step 1. Protect your sink
Place cardboard or plastic on any surface around the mirror.

Step 2. Cover the mirror with duct tape
The duct tape will limit the amount of glass or shards if the mirror breaks during the process

Step 3. Use a hair dryer to loosen the glue
You can also use a small heat lamp.
Dry every corner of the glass evenly. Concentrate the heat flow to areas with a lot of glue

Step 4. Ask someone to act as an insurer
Since you will be removing the mirror from the wall, you will need help to catch the mirror in case it slides down quickly. Especially if the mirror is large

Step 5. Tear the edges of the mirror away from the wall
Use a long spatula for this.

Step 6. Use string wire with both hands
Saw with your hands. This will separate the mirror adhesive from the wall.

Step 7. Repeat the process of tearing the mirror off the wall and heat up the glue if necessary

Step 8. Tear the mirror off the wall
Use a pry bar after sawing off more glue.

Step 9. Move the mirror down the wall
Advice
- You may need to repair drywall after removing the mirror and before installing a new one.
- If you're not worried about keeping a mirror in your bathroom, cover the mirror with plastic and smash the mirror with a hammer. The plastic will catch the debris and take a lot of weight, making it easier to remove the mirror.
- If the bathroom mirror is not attached with glue, it will be much easier for you to remove it. Remove the brackets with a screwdriver and carefully lower the mirror down.
- If all attempts to remove the mirror from the wall have failed, cut drywall around the mirror.
Warnings
- Do not remove the mirror yourself. Ask someone to help you.
- Do not try to remove the mirror with your bare hands. Wear protective equipment. Wear protective gloves and goggles.
