I use glass for the same reason. IMO, tubs and the like just feel thrown together. I haven't had all the issues with heat and humidity that turn many people away from glass. Basically, I use a 1/4in thick piece of tempered glass that covers half of the tank top. I have an EXO Terra light hood that rests on top of the glass. That cuts down on the amount of humidity lost to the surrounding air and decreases the impact that the heat lamps have on humidity. I also use very low wattage bulbs, 25w day, and 15w lunar. On the hot side of the tank, i have a small wad of damp sphagnum that sits in direct contact with the glass bottom, right on the UTH. It's in the corner under a thin layer of substrate.

Another option to try is getting some sort of wood cage furniture. You can use a little branch of grape or mopani. Soak it for a bit in hot water, dry off the excess moisture, and put it in your enclosure.
