I have a 30 gallon breeder tank, UTH , 2 hides, 1 large flat water dish, I use a thick towel over the side with the hide& UTH. The other side, I have the red nocturnal heat bulb., my temps stay between 88-95. The room temps here is about 70-75. I also use a small hand towel/wash cloth wet it & hang it in the middle of the tank, that helps with the humidity, also misting throughout the day.
