Reviving an old thread here. Lots of good information. I have a bathroom VERY much like the OP. Hallway bathroom. Raised foundation plywood floor from the 70s. It currently has laminate floor (poor choice put in by PO at time of sale). I put down laminate in the hallway and most of the rest of the house.
It looks like I have a good set of instructions here from the best, but my main worry is the
stack height of the tile and hardibacker exceeding the hallway significantly. With a door, I can't do any of this wedging tricks seen above. How can I check this without ripping up the existing floor? I want to plan this out carefully ...
My plan is to pull out the vanity and toilet, tile all of that, and then install a new vanity and re-install the toilet (if it still meets my wife's spec, not fitting the vanity). The tub will stay, it is pretty decent, aside from the 80s color. New shower door will be all it needs. I have only laid tile once in my life helping a friend. I think I can handle it. And if it doesn't come out perfect, that's fine - I never use that bathroom. Only the kids and guests!
