Remodeling problem - floor

I just recently had my master bath remodeled to fix a shower pan leak. We had the entire shower replaced and the floor tiled (we had carpet in the master bathroom). I just started using the shower 04/25/05 and now, right where the carpet and tile meet, water's coming through the floor and getting the carpet and tile wet. This is near the shower but I don't see any problems w/ the tile directly by the shower. The carpet gets pretty wet after we've taken a shower. Is this something that might possibly cause us rip up everything and start over?

IT would be hard to imagine a shower that was installed even slightly correctly leaking this soon. Until you know what and where the leak is, it is impossible to tell if it is a minor repair or adjustment, or a major rebuild. It could just be a leak from a loose shower arm, for example.
