We desided that we are going to add a knock down texture to the ceiling. We scraped all the terrible 'popcorn' off, but it being perfectly smooth is unlikely so a light texture just makes good sense. It'll hide the little issues.
We've also reconsidered doing wainscoting. We were considering it originally then decided not to do it. Now we are going to do it again. Of course that could change again before we are done.
I think we are about ready to get the backer board on the floor and get the Kerdi on the shower walls. That means tile shouldn't be too much further out.
