I LOVE this tub! Sterilite tub with locking lid. You can find it at WalMart and its really nice. Its a 34qt so its a perfect size for an adult BP. The handles on the end snap over the lid very effectively locking it into place.
Don't use a CHE with a tub - even on a dimmer, it'll get too hot for the plastic. If you turn the dimmer down too low, it won't effectively heat the tub. A UTH on a thermostat is the best way to heat an individual tub. Vypryz made a sticky thread on how to set up a tub and that's a good set of instructions to follow.
I set up my tub according to his directions and its worked really well. I used an Ultratherm UTH (6x11 size) from Reptile Basics on a t-stat for my tub and I have consistant ambient temps at 78-80 and hotspot at 92. No other heat source is used and my home is kept at about 74.![]()
