We are currently in the process of building a larger indoor Tegu enclosure for the winter months. The room the enclosure will be kept in is pretty drafty (the entire house is hard to heat and cool due to it being EXTREMELY old... like turn of the century plantation style old) so I want to make something that's going to hold heat fairly well. With that in mind, this is what I've come up with, and I'd like opinions and thoughts.

I've purchased a large rubber stock tank - about 4 feet long and 2 foot deep. We are cutting a piece of plywood for the top to fit securely - each end of the top will have a screened "window" for airflow and also to place lights on. In the center of the top will be a hinged door for getting into the cage.

Planning on having cypress mulch bedding, a kane heating mat with rheostat (already purchased) as well as the necessary night lamp and Powersun lamp. I'm thinking I'll need the 160 watt Powersun bulb due to the size of the tub.

What is everyone's thoughts/suggestions on this?

I can send pics when we are a little further along.
