Tools and Materials You Will Need
Essential Tools
You only need a drill, a tape measure, a pencil, a level, and a screwdriver. These basics help you measure, place, and secure the mirror so everything sits straight.

Studs offer natural support. If your mirror lines up with one, great. A stud finder helps or you can tap the wall and listen for a solid knock.
