Shower Disaster

Doesn't look too bad.  The owner called me because he noticed a little leaking.  The shower head is on the upper left side.      

 

The right lower wall was soaked every time someone took a shower.

No waterproofing on this wall.

About all that's left here is the cement board on the tub deck.       

The shower floor did have a membrane. However water ran down the wall and behind this membrane into the subfloor.   Yes - I did fall through this.
