Inspecting the Shower Pan
Factors Contributing to Shower Pan Leaks
If you are dealing with a leaking shower pan, it is important to understand the common factors that can contribute to these leaks. Some of the main culprits include age-related deterioration of the pan, improper installation, faulty seals, cracks, and poor drainage.

Little cracks and damage can easily go unnoticed, so it is important to conduct a meticulous inspection of your shower pan. Start by examining the grout lines and seals for any signs of wear or damage. Use a flashlight to look for water stains or mold growth around the edges of the pan. Knowing the early warning signs can help you prevent costly repairs down the line.
