I measured my floor space. My bedroom and bathroom are 46 sq/ft and my entire place, including the bedroom/bath is 266 actual. One reason the bedroom is so small is that the queen bed has no flooring under it - just built on top of a storage place.
So, 300 sq/f should do everything. I found a guy that has 550 and he's lettimg me have it for $300 if I take it all,. It's laminate and 1/4" thick, nice looking stuff but the picture is he has posted is not so great. So I think I'll take it though.
