Just take a look at this.

This is what happens when a whirlpool tub leaks. You'll hardly ever see it from the inside because the perimeter of the tub is caulked. It leaks out the weep holes on the outside.
There was a new shiny "Quality Assurance" inspection sticker from the Builders third party inspection company on the Kitchen cabinet door.
Guess they forgot about the whirlpool tub...
