The ground floor bath has two doors to allow entrance from either bedroom. The original clawfoot tub was replaced in the 30s or 40s with a cast iron corner tub. It leaked when we bought the house so we decided to replace it with a cast iron tub.
Step one was to find a tub. Craigslist led me to a tub in great condition with all the hardware and nickel feet that would polish nicely. Thanks to most of the underwriters in the office, we were able to carry the tub into the north bedroom.
Step two was to eliminate the tub, toilet, and floor. That took some work. The original floor was black linoleum. Everything comes back in style eventually.
Step three was to remove the toilet. That happened faster than I wanted. Mark Strand came over one day to help with some plumbing. He watched me take a couple swings at a stuck pipe and just as he started to warn me, the hammer backswing hit the toilet tank (fortunately the old one) and water went cascading everywhere.... just as Jacquie walked in and heard the crash and waterfall.
Step four is to reassemble. That step is still ongoing due to my desire to unstick the windows and strip the paint around the vanity. Nearly done with the repainting of windows and vanity trim.
