I have rack systems for most of my BP's, I also have a fairly large custom made enclosure I made far an adult female i have & to tell you the truth the adult very very rarely comes out of her hide. the floor size on the enclosure is approximately 3.5 x 2 ft & she only uses about 1x2ft the only time i ever see her use the whole thing is when she is hunting for her rat. I think as humans we think its cruel to keep them in a small tote, because we like our open spaces, but in the wild they would find a tight space after their meal & lay there until they get hungry again only coming out to warm up.
