Slowly but surely, the water closet is taking shape:
I've installed the first wall of beadboard. It's really very simple. Cut to size, snap into place. The new stuff isn't an EXACT match to the original that had to be removed, but once it's painted it will look great. I decided to put insulation in the outer wall since the opportunity presented itself, so I have to do that before any more beadboard work. I still need to find the hexagonal tile (everyone seems to only carry the octagonal with squares in between - not as historically appropriate) and a light fixture for the wall also.
