How to Identify Shower Leaking from the Bottom?

Why is My Shower Leaking from the Bottom

Identify Leaking Shower Door

One of the most common places for a shower to leak is the door. The seal between the door and the floor often comes to lose and with the tiny gap between the door and the wall, water leaks from the shower.

For an ordinary shower door, this could happen for two reasons.

  • When the seal is worn
  • The door does not fit correctly anymore.

A worn seal is a common cause and happens eventually to all the showers. The more the seal between the door and the floor is worn, the less watertight it becomes and allows water to leak.

The other reason, why the shower door does not fit correctly can happen for two reasons. First, it was an installation error, and wrong measurements were used while installing this door.

And secondly, time. When the shower door is being used for time after time and it is old, the door loses that perfect fitting to the designated position. This makes the water leak to the floor.

You will know if the water on the floor is leaking from the shower when seeing water on the shower floor right beside the shower door. Even when you have closed the door while showering, water will leak to the floor.

You can also check for wear in the seals and even the smallest holes or cracks can lead to a big amount of water per month.

For showers with a sliding door, the door track is the main culprit for the water to leak outside on the floor. Usually, water gets stored in the door track and they get out back on the shower with small holes.

But, sometimes these holes get blocked with small debris or dirt, and water gets stored in the track. Then, when the door slides back or front, this stored water moves outside of the shower, onto the floor.

To identify if it is the track or the seal, check if the track is putting the stored water back to the shower area. If it doesn’t, the holes are stuck. If The track releases water back properly, check the seal between the floor and the track.
