When your shower door leaks, puddles of water may cause a nasty fall. If the problem persists, mildew can form around your tub or shower. Depending on the magnitude of the problem, it may only take you a few minutes to stop your shower door from leaking.

  1. 1

    Identify the source of the leak. Turn the shower water on and close the door to see where the water is dripping from. Once you pinpoint the problem, turn the water off. Wipe down the area of the leak until it is completely dry.

  2. 2

    If the problem is a crack at the base of the shower track, apply a thin line of caulk to fill in the crack. Use a caulking gun or a squeezable caulking product. Use a caulk finishing tool (see Resources) to remove excess caulk from the area and fill in any gaps. Allow the caulk to dry for at least 24 hours before using the shower.

  3. 3

    Replace the shower door sweep--the rubber strip at the bottom of the door. The sweep may not be thick enough to fit snugly in the track. Measure the space between the bottom of your shower door (not including the sweep) and the track. Remove the door from the track. Remove the sweep from the bottom of the door and replace it with a new strip.

  4. 4

    If the problem is a shower door that will not close completely when you slide it to the wall, measure the length of the shower door. Apply a rubber strip (sweep) to the wall where your shower door hits--or to the shower door itself. Snip the rubber strip as needed so it will fit the length of your door.

Tips and warnings

  • Spray your shower doors and tracks with a mildew remover frequently.
  • Use a highly absorbent cloth, like the Absorber or Sham Wow, as your shower mat to trap moisture on contact.
