I don't use cementitous backer, I'm to old to be lugging that heavy stuff around. My go to is Schluter Kerdi board or Kerdi on walls. Floors get Ditra or Dirta Heat.
Well I’m also well into a bath remodel and even though I’m probably older than Tom [poke] I am still willing to lug that cementious based product around. It’s just my knee jerk reaction to using a belt and suspenders approach. It’s also the difference between doing this stuff for a living and doing this stuff for fun. Bottom line is, I’m getting too old too fast to not ensure that every project I tackle will be the last time I need to touch it.
I concur with everything thing else Tom has stated and will be using Kerdi membrane over the cement board and using Ditra Heat on the floor. It appears to be a well thought out system.
There will also be no shower curb. Just another obstacle you have to hurdle.
