Tile substrate for bathroom stone tile

Hello, just joined- first post so here goes;
I am a carpenter and familiar with subfloor systems. I am tiling 12 x 12 stone on my bathroom floor in my own 1920's four square. I'm installing 1 1/8" thick subfloor as per several
Recommendations from this site. ( passed deflecto test) My confusion starts from this point. Have seen lots of as you call them " jersey mud jobs" up here in Canada ( metal lathe and scratch coat I assume) but on these threads it seems most people are using 1/4" or 1/2" cement board. If I am correct so far, why is this the preferred method over jmj.
Thanks,
Steve J

Steve,Welcome to the forum.

Just to be sure - your plywood is in two layers and installed as per Frank W's article?

The CBU is to get the tiles to stick to the plywood. You can use 1/4" (properly installed) 1/2" if you need the added height, ditra, greenskin, or a another sheet membrane. I vote for GreenSkin.

Welcome, Steve.

The difference between the CBUs and the Jersey Mud Job is effectiveness and consistency. The CBU panels are very consistent and tested for effectiveness and known to function well. The Jersey Mud Job under the same testing fails far too frequently. Up to you what you use.

Very unusual to have a floor joist structure that meets the required L/720 for a stone tile installation unless it was designed for that.

And, as Paul points out, your subfloor for a stone tile installation must consist of two layers. Object is to ensure that you have no subfloor joint that extends from the joist tops all the way to the subfloor surface.

My opinion; worth price charged.

Stone tile subfloor

Thanks for the prompt advice. Subfloor will be two layers.
What is the preferred adhesive for plywood layers?
What is the preferred method for securing cement board to ply
What is the preferred method to attach electric in floor heat ( cables or mat, haven't purchased yet) and in what order of floor installation does it go?
Thanks,

Steve J
