How to Patch a Shower Base
Repairing a shower base is not as difficult as it may seem. (shower image by Dragan Trifunovic from

The base of your shower, whether made from fibreglass or plastic, can crack and cause leaking. If this happens, you can contact a professional or replace the base yourself. For small cracks in the shower base, you can actually patch them to save yourself money and time, and you won't need to replace the shower. A small crack in your shower base will require less than an hour of work, but you'll need to let the patch dry for several days to seal it properly.

  1. 1

    Clean the base of the shower with tile cleaner. Spray the tile cleaner and allow it to sit for a few minutes before scrubbing it with a damp sponge. Rinse the tile cleaner completely with hot water.

  2. 2

    Find the cracked area of the shower base.

  3. 3

    Sandpaper the cracked area to remove any sharp edges.

  4. 4

    Cut a piece of fibreglass cloth to the shape of the crack of your shower base. Make the fibreglass cloth a half inch bigger in diameter.

  5. 5

    Apply epoxy to the crack in the shower base. Place the fibreglass cloth into the crack in the shower base. Press down firmly until the patch is as smooth as possible.

  6. 6

    Place cellophane tape over the cracks as tightly as possible to make sure that the crack holds together until everything is dry. Allow the patch to dry for two to three days to ensure that the crack is completely sealed.
