Alright, I hope someone on here has some knowledge of this. I"m getting a pro to ask but maybe someone knows off the top of their head.

The shower liner, does it go on the inside or outside of the drywall? My gut tells me they did something wrong in my shower, here is a teardown photo to try and find a leak.

The drywall however watter proof seems to be between the tiles and the liner, is litterally soaked and was instaled all the way below the base. I'm no expert but it just doesn't look right.
