I'm about to lay tile on concrete for a shower.Problem is not sure on how to go about pitching the floor, because the floor was not done that way(new construction) and bit lost oh how and if I should use floor liner? Someone already laid harded backer on walls can some please HELP!!

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 (http://www.swanstone.com/products/showerWallsFloors/?PHPSESSID=a713c5cf2011a4b49eb095913664ecaf)

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 (http://www.hoagy.org/house/HowToBuildShowerPan.html)

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.
