The water service to the tub was a real bear! I had to make an access through the wall coming in from my study. Once it was all done, it seemed pretty simple. But getting there was quite a bit of work.

The access panel in the study will be trimmed with oak that matches the bookshelves. Since the location is beside my study desk, it shouldn't be too conspicuous.

The angle iron at the top with the 1/2-inch hole will be drilled through with 2 each 7/8-inch holes to mount the faucet.  If all goes well, we should have a faucet that can't be pulled out of the wall by over-exuberant grandchildren.
