I can't see any visible damage, so how could my shower pan be leaking?

While grout between the tiles works to force most of the water down the drain, it's the shower pan liner underneath that provides waterproofing. This pan liner is installed just after framing the shower and before any mortar or other materials are installed.

When water inevitably seeps below the tile and mortar, it meets the pan liner to prevent leaks. Unfortunately, the pan liner may not be installed correctly or suffered a tear during shower construction.
