The problem is that when you put in the shower pan (floor), it needs to slope 1/4" per foot. In order to look good, you need the same drop from each wall to the drain. That means you need about 9/16" in 6" on the short side. If the drain was in the middle of the 32" (and that is a small shower!), then you'd only need about 5/16ths drop from each wall to the drain.
You really should consider moving the drain to the middle of the shower, then you'd have a bunch of options. If you want help with tiling, consider going over to johnbridge.com probably the best tiling site on the web. They have a bunch of good people (and are friends of Terry's), plus a good library where you can do some research.
