When we were browsing on the 'net looking at places out there, we noticed alot of homes have carpet. EEeeewwww....
You could go with a linoleum product. They've come a long way since the garbage of the late seventies and early eighties.
You probably already have this planned, but in the full bath/baths, put in a heat lamp just outside the shower/tub so when you're drying off you have that nice warm heat bathing you. That should help if you have to use tile.
I'd use tile with multiple rugs.
