Replacing a Standard Shower Door Bottom Seal 


  • First, open the shower door fully and inspect the bottom of the door to determine the seal attachment method. In standard shower doors, the seal strips are usually just slid into the bottom of the door. Therefore, it’s pretty easy to remove them (especially when the seal strips have become brittle).
  • Just hold the seal and pull it out of the door. Note that one side of the bottom seal strip will have a drip edge or lip, so install the seal by facing the drip edge inside the shower.

Note: You might need to apply extra pressure if the mineral deposits are holding the seals in place. Carefully grab the seal strip with needle-nose pliers and pull it out of the door.

  • Wipe the bottom of the door with a damp cleaning rag to remove any dirt or mineral deposits. Use ammonia-based glass cleaner to get rid of mildew and soap residues. Wipe the bottom with a dry rag.
  • Now, take the replacement seal strip and align it along the bottom of the shower door. Install the strip by pressing one end of it onto the bottom of the door. Then start working your way towards the other end of the door bottom. Make sure that the seal is tight and in place.
  • Once you have installed the seal, slowly close the shower door to ensure that the seal is working fine. If the seal is rubbing too hard on the floor, push the seal upwards to set it in the right position.


The bottom seal strip is replaced and your shower door is as good as new.
