Excellent progress! I know the feeling when your covered in dust/rubble/sh*t and you never think you'll finish. I took down a lath and plaster ceiling in a house in Liverpool and all sorts of stuff dropped down on me! The roof insulation was about 2 inches of shredded newspaper and I found a whole one from the 1930s.
Kinda makes me want a little project now!
By the way, is it an optical illusion or is the shower plate not level?
