Steven, it'll help if you'll keep all your project questions on one thread so folks can see what you're working on and what's been previously asked and answered. A moderator can give it a more generic title any time you'd like to suggest one.

For a shower floor or pre-slope I would not hesitate to make your deck mud that thick at the perimeter.

My opinion; worth price charged.

What's on the area beneath? If it's gravel or soil, think twice. YOu want a stable surface that is connected to the slab before building a shower pan.

For a large area like that, I like to drill into the edge of the slab and insert the rebar as far as possible.

Do not use deck mud or topping mix to fill that hole,use rebar and concrete mix. Do not mix the concrete wet and soupy. The wetter it is the weaker it is.

Then you can set your drain and do your deck mud. Laticrete call for aprox. 1.25" of mud at the drain. Add in about .75" for slope and you will be about 2" at the entry of your shower. How are you going to address that to make the shower curbless? Are you planning to mud the entire bath floor and have a fairly high transition at the doorway?

Thanks CX, I will keep all my questions related to the current job in this one post from now on.

I was considering using the rebar as was suggested by multiple people but I think my question was overlooked.

"How far apart should the rebar be placed, how far should they stick into the old and how much should stick out for the new for the new to get a solid joint?"

Also concerned about the rebar rusting out. Should I be?
