See the crack at the bottom of the surround? It couldn't begin to hold enough caulk to keep the water out. This picture was taken after we pulled all the old caulk off which led to the surround tearing, my husband saying a few choice words followed by "Call Buzz (our friend/handyman/brother-in-law) and see when he can tile it" ~ Yea!!
This is what it looked like after the tile was complete (we didn't have the curtain up yet). It's still the toe cracker but at lease it looks better and doesn't leak!
