safety but not all that much.)

In a room/house where temperatures fluctuate wildly (cold winter/hot summer) I highly recommend that you insulate whatever cage you use, and the best
way would be a wood cabinet around the snake's enclosure, with only a minimized front window for viewing. Snakes love their privacy anyway.

If you use only a plastic tub of whatever size & UTH that's hot enough to give adequate warmth to the snake in the winter, I am very concerned that without
the cage being suitably enclosed, the heat will not only warp the plastic* but also could be a fire risk. Please keep safety in mind. (*I personally prefer glass
for safety etc, but I don't currently keep BPs. Popular opinion here is that plastic works best for retaining humidity. There are ways to make glass work too.)
You evidently are not too familiar with racks are you?
Second, properly regulated heat sources will not do any damage to tubs. If that is your thought process then you probably shouldnt hold one in your hand for too long.
