The tub setups I've seen are all fundmentally a set of dresser drawers. I can see the efficiency angle, but for a person that has one or two snakes it just doesn't seem that great.

When you use tubs do you just have to take them out anytime you want to see them? I love peeking in even to just see a part of my BP's body in his hide. That's when I say "I see you Snakey.... I see you hiding in there....".
