Ghanging bathroom into a standing shower want to build my own floor

Stancill,
You've piggybacked on a 4 year old thread so I gave you one of your own. What, exactly, are you asking? In the meantime, answer a few of my own.
What type of shower do you wish to build? Custom tile? Shower on a slab, no tile? What?
What material are your drainage pipes? Copper, cast iron or plastic?
Come back with more details. The more the better. Regards, Tom
