Symptoms
- Puddle forms on the bathroom floor outside the shower
- Leak happens mainly at the bottom corners
- Rubber strip along the door bottom looks cracked or missing
- Door closes fully but water still seeps under
Likely causes
- CommonWorn or cracked door sweepThe rubber or vinyl strip along the bottom of the door degrades with age and hard water exposure.
- PossibleTrack not sloped correctly toward the shower interiorIf the base track sits level or slopes outward, water will escape regardless of the sweep's condition.
- PossibleGaps at the door's side seals or magnetic stripsVertical seals along the door edges can also wear out and let water through at the sides.
- Less commonShower head aimed directly at the door gapEven a good seal can be overwhelmed if the spray hits the seam directly.
What to do
- Inspect the door sweep along the bottom edge for cracking, gaps, or missing sections.
- Measure the width of the door and purchase a replacement sweep sized to match.
- Remove the old sweep by sliding it off or peeling away old adhesive, cleaning the door edge afterward.
- Slide or press the new sweep into place, trimming to length with scissors or a utility knife if needed.
- Check the side seals and magnetic strips for damage and replace if cracked or no longer sealing.
- Adjust the shower head angle so the spray doesn't hit the door seam directly.
- Run the shower and check the floor outside after a few minutes to confirm the leak is resolved.
Tools and parts

When to call a pro
Call a glass shower door specialist if the track itself is not properly sloped, since that may require reinstalling the frame.
