While true I have a similar setup for a baby boa in QT in my master bedroom and the ambient in the room is 70*F at the moment. I'm using this tub - 6.2 qt Sterilite latch box:

I like this one because it's short with lots of surface area. Put the heat pad under 1/3 or even half of it, and it will warm up inside just fine.
