Looking through the entry door. The view straight ahead will retain the vanity; we'll replace with a double sink. To the left in the foreground is the existing shower stall. That comes out and will be replaced with a 3'x6' shower, part of the expansion pushing out the back wall. The new toilet will be tucked around a new wall where the shower is now.
The wall between the shower and the vanity area. I took the first layers of tile and drywall out this weekend. The shower side tile and drywall will come out next, and then the studs. I'm getting pretty good at demo. I have no skills for putting anything back together, but that's a different issue.
Note the intercom system which is next to the toilet in the current layout. I don't think we'll be keeping that feature...
