We felt it needed to be a complete rebuild. There was lots of water damage, bees in the rafters and wood rot. Everything was leveled and rebuilt. The total size is 8 by 7. We found an old window that had been boarded up. The was even newspaper from the 50s used as insulation.
Yes even a bath this small can feel like a spa. They make whilpools for every size. We had to cut in to the 2x4s, as you can see, to get the pipes to fit.
