Is the leak out into the open area on the floor when you step out of the shower? Does yours have the Shub Shower retracting shower screen?
If it does, odds are high the silicone caulk along the length of the shower track that mounts on the shower basin for the Shub Shower screen (at the floor area) is gone/cracked. We had to scrape out the old caulk and put fresh new caulk in and the leak went away. Lift track up and caulk back down. The caulk holds the majority of it in place.
See this thread, it talks about the caulk and has pics of mine
There is one other source of shower leak, the drain fitting. This leak ends up going under the shower basin and then where ever it wants to end up. Somewhere in your layout is an access panel to get to the shower drain trap. Take that panel off and you can see an aluminum nut on the shower drain. If this is where the leak is, tighten up the nut. This has happended before. If you need a pic, I have some, can post later tonight
Hope this helps
