moisture meter or infrared camera. We like to use hot water to fill the shower floor, because leaks show up as bright yellow hot spots on our infrared camera, as in the photo sequences below of the shower curb and the common wall of adjacent closet.

   Sometimes visible evidence of a shower leak is on the exterior wall. The wet stain and green algae growth on the side of the floor slab in the photo below aligned with the side of a master bathroom shower, and the area gushed water when the pan was tested.

The labor and materials cost for a new liner, mortar bed, and tile replacement make a failed shower pan an expensive defect to repair. Plus, the potential for damaged wood wall framing and mold growth in the wall cavity if it has been a long-term problem may increase the cost further.

   So be sure to ask your home inspector to do a shower pan test during the home inspection, especially if it is an older home. However, it is worth noting that a shower pan test is not required by the Standards of Practice for home inspectors under Florida Statute 61-30.806, which states that “the inspector is not required to test shower pans, tub and shower surrounds for leakage.” So not every inspector will do it for you.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
