I promised some pictures
We have bathroom! All functioning and flushing and no leaking or other issues!
new light fixture and medicine cabinet
old sink with a few faucet makes ALL the difference
the floor before the edging tile and toilet went back in
The area you see beyond the step will be screened off for now. There is the bathtub back there, but that whole section might need to be demolished (long story), so we'll just hide if for now with a nice curtain until we decide what to do.
Now all we need are a few finishing touches, but WOOT! new, functional bathroom!
