If you aren't building a rack, and if she is big enough, I would go with an Iris CB-70 tub. They are the perfect adult BP size, and have a nice sturdy snap-on lid (though I would recommend clamps around the lid for extra security). In normal room temps, you may need to heat both sides to get the right gradient, but 11" flexwatt or an UTH on one side with a good thermostat may work fine (set at 95 degrees F, you will not even be close to melting the plastic). You will be surprised you much better plastic tubs holds heat and humidity if you are switching over from a glass aquarium.
