I was going to build a shower from scratch, even going as far as welding up a nice stainless pan, but I ended up buying a fiberglass 32" x 32" prefab from a big box store. It was cheap, easy, and quick. In the end this worked out very nicely for my project.
It is difficult to get good pictures of it because of the close quarters, but it as I see it it looks nice, and a "full size" shower works for our use pretty well.
Superat stultitia.
