AAAAAAAAAAAAAGH!! Actually, I think he's sort of cute, but like the cartoon ghosts hanging around in the castles in Mario Brothers games, he's probably got a dark side, too.
As you can see, we now know where the tub was originally. These holes indicate where the hot and cold lines and the drain were (notice the odd offset ... I found a set of pipes with the same offset at Vintage Plumbing, so it's not just a case of bad measuring). Also, on the wall behind the tub are the ghosts of two shelves, and on the wall beside the tub are two round spots that probably indicate where a towel bar was (see pic below with the pink arrows).
Based on this new evidence, our plan is to install the clawfoot tub in its original location. Hey, the holes are already there, so why not? This way, the sink will now be directly across from the toilet and closer to natural light to allow for my beautifying treatments (see the new shoebox arrangement below).
I'm still debating what to do about the sink. We might stick with a pedestal or do a sink-in-old-dresser deal, maybe with a marble top. Not sure. I hoped that when we got the whole bathroom demo'ed and cleared of debris, the right solution would just come to me. So far, nada.
Anyway, I'm happy it's done.
P.S. Check out the cool paper lining the bathroom drawers. Sadly, it is water damaged.
