More humidity, modify the opening. Need more heat in a tank? Insulate most of the sides & bottom...easy to do & many cheap ways to do it.

Glass allows me to see my pets & what's going on. I can add privacy to a glass tank, but adding windows to a tub? Not so good... Not a fan of plastic at all.
True. But pvc cages are already insulated, and the nicer ones come with sliding glass display doors.
