"I'm fixin' a hole ..."
All have known about the water problem from the upstairs bath since Day One.

We articulated to our contractor our desire that the water not leak through the new subfloor, through the newly painted ceiling and drip onto the newly laid red oak floor.

Despite our consultation, the contractor did little, simply caulking the shower. Consequently, wood had to be replaced before the floor could be finished because several pieces were water damaged.

Looking into the hole in the ceiling, it's clear that the upstairs shower must be replaced entirely.
