Final planning for hall bathroom remodel
This is my first time tiling over a wooden subfloor. I'm about to start the remodel on the upstairs hall bathroom. This is a tub to shower remodel, the current floor is tile which I'm assuming is mounted on concrete backer board given the house is 25+ years old and appears elevated above the subfloor in the hallway. I'm trying to figure out what I'm going to find when I do the tear out and how to restore the subfloor to the condition to install new tile and the shower. Was watching a recent Landberg video and it appeared he used self-leveling to prep the main bathroom floor due to the damage to the subfloor during tile/backerboard removal during demolition.
I was already figuring I'd need to use self-leveling for the former tub area to ensure it's level and ready for the RRS shower pan. Reading a post from February is seems that if the rest of the floor is out of level then doing self-leveling over the new Hardibacker is the correct approach our would doing self-leveler across the entire bathroom work better? Since my house using i-joists hopefully the floor isn't too out of whack and I'm just dealing with damage to the subfloor as I pull up the old tile.
The cement board might not have been thinsetted and it may come up easy. You wont know until you tear it up what needs to be done.
