How To Test a Shower for Leaks
Several shower components may leak and result in water damage. You should test every part of a shower for signs of a bathtub leak or leaky shower pan.
Test the Shower Pan
Signs of a shower pan leak will be evident under and around the shower. Closely examine the surrounding area:
- In the basement or crawlspace, for a first-floor shower
- On the ceiling of the floor below the shower
- In rooms that share a wall
Stop the drain and fill the shower with 1.5 inches of water. Wait eight hours or up to three days to see signs of a leak. Walk around in the shower while someone else monitors the area underneath. Homeowners should replace pans that are more than 30 years old.
Test the Seal
Test the seal of a shower door track or caulking with a spray from the shower head. Allow the area to dry before re-caulking. If you notice gaps in the grout around wall tiles, you should:
- Look for visible signs of mold or odors
- Have the area tested
- Complete remediation before replacing grout or tiles
A bathtub leak can allow water to get behind walls. This may pose a risk of hidden mold.
Test the Head
A clogged shower head or a damaged O-ring can cause a leak. A homeowner should replace worn out:
Seal around the escutcheon with caulk or putty. Cap the shower head to check for leaks between the head and valve.
Test the Drain
Have someone monitor the area beneath a shower as you pour water down the drain. Drain leaks may be caused by a:
- Leaky drain body
- Cracked flange
- Damaged gasket
- Worn rubber sealing ring
Any of these components can be replaced. Make sure that the leak is due to the drain and not the shower pan.
