If you arrived here you may already have a shower leak.
A Show Pan Leak Detection
You may be asking yourself questions like:
- Why is my shower leaking?
- Do I have a shower drain leak?
- Where is the water under my shower coming from?
The following is a video that will show you how a Shower Pan Leak Detection is performed.
The process is simple, but it does take some time to get the right result.
As you can tell you require some specific equipment to perform the leak detection. But in reality it’s a simple process.
Shower Pans In General
Shower pan leaks can be the #1 most overlooked cause of chronic water damage and mold in your home.
In the 1970s shower pans liners were made out of lead which most didn’t last very long. Nowadays Liners are made from thin, strong, flexible plastic.
Generally, shower pans now have a lifespan of 10-40 years depending on the materials used and amount of usage the shower gets. It is also not rare to see a shower pan leak sooner than that because of in-proper installations or due to a defective plastic liner.
The main piece that fails in the shower pan’s construction is the thin plastic shower pan liner (See Image below).

This plastic liner is essential in keeping the water from leaking/filtering out into the surrounding areas while someone is taking a shower.
Areas where you can notice water damage due to this type of leak is on bathroom walls, around the shower curb, first floor ceilings under shower, and crawl spaces. If not addressed quickly this can lead to bigger issues like mold and cause the subfloor to wet rot. Watch the video above to see how you can test the liner.
This test must be done and is recommended by most building codes during inspections before the tile is installed. It can also be done after tile has been installed as well to test for leaks.
We still recommend calling a professional to 100% confirm this is the cause of your leak.
3 Common Problems With Shower Pans
The 3 most common areas a shower pan can leak from :
- Your shower liner having a hole or rip during tile installation
- A general old or faulty shower liner.
- Around the drain area where the bolts hold the liner down.
- The connection found when the shower is bigger than standard size or a bench / sitting area is placed inside the shower area. These benches might look nice but they are prone to leaks and humidity build up inside the voided areas that cause mold. ( see picture below of an example of a bench in shower pan)
