Anyone have any ideas as to what our problem or how much it could cost
us? The main thing I want to avoid is having our shower re-tiled 2 or
3 times and still not stopping the problem. I have taken some pictures
because they say more than I have put into this entire post.

Thanks in advance for all your help,

Good pics.
There appears to be no watertight membrane commonly called a shower pan,
installed. A licensed 'reputable' tile contractor can install one for
about 1K by removing the shower floor tile and wall tile up 3 rows or
so, like this http://www.thetiledoctor.com/repair/leakypan.cfm
Then installing a membrane like this:

Agreed- the problem isn't the grout, it was a bad install from the get-go.
I'd be as inclined to suspect leakage around the floor drain, since it was
traveling down the outside of the drain stack, and he didn't mention wet
drywall on first floor ceiling. After all these years of leaking, quite
likely the subfloor under shower is rotted, and maybe the top of the joists.
Adding a pan over all that is a temporary fix- proper fix is to gut the
shower, replace rot as needed, and build it right this time. Seaming in the
tile field, while possible, takes a real talented tile guy to not look like
a patch. Probably not much more labor to rip it all out. If they cheaped out
on the floor pan, they probably also used greenboard rather than concrete
board for the wall backer anyway. OP can save money by doing the demo and
installing the new backer board himself- that doesn't take an expert.
