Finally finished up this project.
Two coat mud on the walls, 1" mud bed on the floor with lath/paper/easy heat. Laticrete hydroban sheet membrane on the pan, Laticrete Hydroban on the walls.
32" laticrete linear drain.
his/hers shower left and right, with a soaker tub below the window. I'm not crazy about the pan being flat under the tub (but it had to be) in case of overspray from the showers. But the whole room is waterproofed with Hydroban sheet membrane, so it won't hurt anything even if it does.
I don't know how I would have done this job without learning mud work. (still have lots to learn admittedly) and I will thank the JBF forum and the "mud work hints and methods" thread for that.
