You could stop using it for a few days, let it dry some, plug the drain, and then fill the shower pan to see if the water is leaking from the pan.

Good call! We actually haven't used it in the years we've been here, so this is water damage from the previous owner. However I hadn't thought to put water in and plug the drain-great idea to be certain if the tub is leaking or not
