@KoiwiGal - That does sound nice, and it will probably last longer than a tile shower pan since, as it says in the article, those tend to leak.
I have just a fiberglass shower pan in my house, which is nice enough, but unfortunately the shower looks like it is a relatively recent addition to the house, and it wasn't planned properly when they put it in. The floor in that room is wooden and I think that there is enough humidity and water leaking out that the wood isn't going to last long.
Of course, I'm renting so there's not much I can do about it, aside from let them know. It drives me a little nuts though, when people don't make sensible decisions that will save them money in the long run.
