I have seen the fixture that gulfstream uses in there shower. If it is a 2 handle faucet set on 4 " centers same as a bath lavetory faucet. I wiil bet the fixture behind the shower wall has cracked. This is a week point in the water system. If you have ever hooked up to an overpressure or even a high pressure source it will crack at this week link. Its an easy fix if like most the fixture is mounted in a box that is then mouinted to the shower. Hope this helps I had to replace an entire section of flooring and sub-floor to learn this info. Again hopes this helps.
