Building a cement/utility shower in basement.

Greeting gents (and ladies). The last couple of weeks have been stormy and rainy in Indiana. Subsequently, my basement, which is often prone to getting damp anyway, flooded, due in no small part to a ruptured sump pump discharge hose which put about 350 gallons of water into my basement.

So, I had to completely demo my downstairs bathroom. It wasn't a huge loss, considering how wet it had been over the years and how poorly built it was. I plan to reframe the room in steel and use green board and cement board to rewall. The catch is I would very much like to make this bathroom "utilitarian" in nature, meaning, that I could hose the dog off in it, get it wet, and not have to worry a whole lot about water damaging anything, especially if I get another wet basement :whistling2:

So I planned to build a cement shower area. My ignorance led me to believe that I could simply curb-off an area in the bathroom near one of the two drains in the floor, and VOILA, shower area. However, I've since learned this may cause severe damage to the concrete. I then saw the agonizingly complicated process of building a mold, pouring portland inside it, extending the drain, putting down roofing felt, putting down a bladder or liner, then pouring finish cement. This looks stupid complicated, quite frankly, considering I"m already on a concrete floor with a masonry brick wall.

So any suggestions? I'm very much against a pre-fab shower kit which requires assembly and might last ten years of light use. Not to mention, I would have to raise it up off the floor about six-eight inches in order to plumb the drain. I saw some shower pans at Home Depot that are "tile ready" and look like just what I need, but the prices (nearly $600) are absolutely ridiculous. Any guidance is appreciated.
