I wouldn't reccommend something like that. You can heat tubs using a UTH (under tank heater) or by flewatt (heat tape) Reptile Basics sells heat tape. Thermostats regulate heat sources such as a UTH or flexwatt, to ensure that you don't burn your animal. I wouldn't recommend using those kind of tubs, because I'm not certain that the heat tape wouldn't melt them. You can always build a rack, that way you can build it exactly the way you want it.
