Thank you for the responses, I appreciate it!

The average room temp is about 73 during the day and I lower it to 68 at night, but the bathroom can get to 77 if I keep the door shut. I'm not sure if I'd be able to fit the tubs in there and still be able to use it though, as it's very small. Other than that it's just a couple of closets and my room as far as the apartment goes. Both of the tubs are sterilites, I can't remember the quarts...measurements are given up top though. The lids will be secured down with some heavy duty binder clips

The only other option I can think of aside from glass tanks is to bump up the thermostat in my own room to 75 or so and leave it on 24/7, but the cost of heating at these apartments is ridiculous enough as it is and I've already spent a large amount of money on supplies for these snakes. Just not sure why tubs are apparently working fine for these people but I can't get them up there. They're actually even a degree or two *cooler* then the surrounding room temp
