How to Hang a Plate-Glass Bathroom Mirror

Framed mirrors are simple to hang because they usually come with hooks, brackets or hanging wire mounted on the frame. However, plate-glass mirrors are flat and do not have any hanging hardware. They must be secured to the wall without framing. Due to the weight of glass, properly securing a plate-glass mirror is a safety concern. If you do not securely fasten the mirror to the wall, it can fall and break, causing injury to you or damage to the room or mirror.

  1. 1

    Measure the length and width of the mirror with a tape measure.

  2. 2

    Use a pencil to draw a line across the wall where you want the bottom of your mirror to rest. Draw the line the length of the mirror. Use a level to make sure the mirror will hang straightly.

  3. 3

    Draw another line, the same length, for the top of the mirror. Space it from the lower line by 1/4 inch plus the height of the mirror. Use the level to make sure this line is also straight.

  4. 4

    Cut two pieces of J-channel with a hacksaw. Cut each piece the length of the mirror.

  5. 5

    Find the studs in the wall along the pencil lines with a stud finder. Mark the studs by drawing an "X" where they are located along the lines.

  6. 6

    Put on a pair of work gloves and hold one of the cut pieces of J-channel along the bottom pencil line. Attach it to the wall with drywall nails and a hammer through the marked stud locations.

  7. 7

    Attach the remaining cut length of J-channel to the upper line the same way you did the lower piece.

  8. 8

    Apply mirror adhesive to the back of the mirror with a caulk gun in 1-inch dots every 12 to 16 inches. Do not place any of the adhesive within 6 inches of the edges of the mirror, or it may seep out and make a mess on the wall.

  9. 9

    Lift the mirror from the sides and push the top edge of the mirror all the way into the top strip of J-channel.

  10. 10

    Swing the bottom of the mirror closer to the wall and press the mirror against the wall firmly. Allow the bottom of the mirror to gently drop into position, keeping your hands clear of the bottom edge.

  11. 11

    Adjust the mirror by sliding it from left to right you centre it along the J-channel. Do this right away, or the adhesive will dry and the mirror will be stuck in place.

Tips and warnings

  • Do not attempt to lift a mirror unless you are certain you can do so without help.
