StormRage has a fully textured bedroom available in the freebies section at 3-D Arena that closely matches your description (window, doors that open and close), but the little sideroom is a walk-in closet, not a bathroom.

I suppose you could always remodel. A little plumbing work, a few fixtures ...

Anyway, it's about 11 pages into the Freebies section, update July 23 2001.
