I have my guest bath torn down to studs. A new cast iron tub went in. I had to replace a few termite-eaten studs from who knows when. The house is 60 years old. I'm working on putting it all back together now. New insulation, then drywall and backer board. Then, moving on to the shower tile. Also, I have to schedule a new stone top for the vanity and get a new sink and faucet. Then, texture and paint all the walls and finally replace all the floor tile in the area. I started a week ago, but it's all moving quickly. If I can keep up the momentum, maybe I will be finished in a month.
