What should I look for when buying a frameless mirror?
Use a straight edge to make sure there are no high spots on the wall.As the glass will not flex if the wall has an outward bulge the glass may break when you tighten the mounting brackets.Make sure that nothing will contact the mirror during regular activities,opening doors ,cabinets,drawfronts etc.It is also not advisable to mount it next to a doorway such as a bedroom door as it might be confused with the exit in an emergency.Think middle of the night and the smokealarm going off.
