PROGRESS!!
Broken old tub is out and the new one is in place, bullshit generic shitter is out. Everything is ready to hook up, trim out and re-paint.
I hope to get a base coat of paint down before I become exhausted. (fucking new fiberglass tub is heavy as hell!) It has really gone smoothly. That's assuming that the heat is enough to dry the drywall patch on the wall. I was afraid I might find some problems from the leaky old tub, but now I'm home free after about five and a half hours.
Painting is my wife's area of expertise.
