We are re-modeling a 1/2 bath, and have removed the old 32' x 32" shower. The
drain is 16" centered from each corner. We want to expand the shower to about
34" x 48", making it a ceramic interior. My question is how do I make a new
shower basin? The drain, I believe, is cast iron, in a concrete floor, and now
stands about 2" from the floor (we removed the old basin).

Thanks. Art

Tom, you are wanting other opinions? I guess I would instal a strainer to establish the height needed, and then frame up the outside about the same height. Then mix up a fairly stiff concrete and slope it from the outside to the thickness of the tile below the strainer. Once the concrete is set, instal the tile leaving it slope down to flush with the strainer.

Lab, I moved this question from corrector001 from my E-mail over here. I have company for dinner so I did't get to answer his question. How about taking up the slack today cuse she's a lot prettier then my keyboard. Thanks Tom PS. Good Answer!
