Pipe dreams

So... I'm still stuck on the bathroom. I found this great little program at Kohler.com that allows you to design your own bathroom. Unfortunately, all you can use is their products, but it gives you an idea of what can fit in your bathroom and where it would look best. So here's what I've come up with so far...






Now, to me, it looks like I might possibly be able to fit a shower in this bathroom. The question is, would it be too cramped? The bathoom is only about 6.5' by 10' (these are rough measurements; I'll take new ones when we move in), so there's really no other way it could be set up with a separate shower. The only other idea I have is to use a rectangular/square shower enclosure, since those seem to be slightly smaller.
