best selection of corner shower units?

We are plumbing novices with an old house & are planning to put a corner shower in a half bath/laundry room (contractor will install). We live in a rural area where shopping choices are limited. Would appreciate any suggestions regarding where to shop (online or stores) & considerations we need to take into account. The space is fairly small. There is a full basement under the room, and we plan to have the contractor remove the lathe & plaster to run electrical lines & new plumbing. Thank you!

The worst shower units I have come across have been by Sterling. Shipping cost, and potential damages, usually make a local purchase more practical.
