Things You'll Need
Flat pry bar
1/8-inch metal drill bit
1-1/2-inch metal screws
A shower door with a metal frame usually has a piano hinge on which the door swings open and closed. Over time and with the use it receives in the average home, the door can begin to sag, making it harder to close. This can cause water to leak out of the shower when it is in use. You can adjust a sagging shower door with a piano hinge using the proper tools and with a moderate investment of time.
Remove the screws that attach the piano hinge to the side of the metal frame. Use an electric drill with a driver bit installed.
Place the smaller end of a flat pry bar under the door hinge and use it to adjust the hinge until the door opens and shuts properly. Have someone hold the pry bar in place once you have the correct adjustment.
Drill holes through the existing holes in the hinge and into the frame underneath using an electric drill with an 1/8-inch metal drill bit installed.
Secure the hinge with 1-1/2-inch metal screws using the electric drill with a driver bit installed. The longer screws will anchor deeper into the frame than the shorter one-inch screws that were previously used in most cases.
