concrete shower

Why not use a waterproofing membrane like "Kerdi" on the walls and floor with the associated Kerdi drain. Then you could apply any kind of tile you wish to the inside wall. For the outside you could find tiles with a stone look, apply flagstone, or cultured stone.

Where I live we would use Hardibacker board or Wedi board. Tile them with whatever you want. Not sure I would use fossilcrete though. Is it rated for a shower? What about Indian fossil stone? Perhaps take the customer to the stone yard and let them select. They would need sealing like Travertine.

What are you going to use for the floor a store bought pan or mud?

I used Hardibacker for my shower too. It's a bit lighter than cement board, and cuts cleaner.

Unless you have a standard sized shower area, or want to splurge on a copper pan, it's fairly easy to slope a mortar bed for a Kerdi membrane. I did our 6'x6' shower that way and had no problems.

could you post some pics of that shower, love to see it, 6x6 is nice size, wanted to go that big, but was too costly at the time for us.

I'll go one better, check out my old shower building thread on the John Bridge forum at:
