Actually, there has been progress.

It's been much slower than I would prefer (there's so much to DO this summer!), but I am making progress!  Absolute key point - the toilet works.  Hooray!  We also hung a temporary door, not pictured here.  It doesn't touch the ground, but at least you no longer have to yell, "I'm peeing, don't look!" when using the downstairs bathroom...

And yes.  Those are 3 tiles you can see on the shower wall!  Showering - hopefully coming soon!
