Thanks Robert, lots of things to try there. A little more detail:

Imagine the top view of the shower stall as an upside down U. The left
edge of the U is flush with an outside wall. The right edge of the U has
a tile wall extending 3-4 feet to the right of a toilet. About 6" of
this actually extends into the U. The leak is at the bottom of that 6"
section, but above the rim around the shower. So I think I can eliminate
the pan and the drain but I will check them.

I looked for missing grout once before and found and fixed a couple of
small places on the other walls, but nothing on the 6" section where the
leak is. I'll try the magnifying glass technique and go over it very
carefully. Thanks again.
