You need to use some grout to get the slope to the drains, tricky to get just right if this is your first time doing this. Or you could use a pre-fab shower pan.

Rodger:

If I understand you correctly...

Do not just use grout to slope tiles to drain... need to have some kind of pan here... ;)

I like Amricca's idea of a prefab shower base... ;) Fewer issues in the long run... check out this link:

Swanstone Shower Walls & Floors

Prefab shower floors need to be set in a bed of modified thinset mortar or similar.

Otherwise, you need to install a PAN of some kind (can be copper or membrane type pan).

Check out the link below... it shows you exactly how to build a custom pan. I would not skip a single step.

How to Build a Shower Pan

I would also remove the bottom layer of the cement walls, run membrane up wall at least 6-8", then install the concrete board in place (do not screw into bottom 6 inches of the membrane/cement board)

Let me know what you think... Mark

I agree with Mark and amricca about the Swanstone, I use them pretty much exclusively unless the home owner makes a strong request for something else. Its been years since anyone even asked for a custom pan and I like the short cut of Swanstones easy installation. A 32x60 would run you under $300.
