Yeah! I'm glad you had the same idea as me. A lot of the 'how-to's I've read build the entire thing of wood and then put the heater on the inside, with holes in the wood for airflow, then put the tile over it. I was like...why not just put PVC on the bottom...lol.

How big is that enclosure? Is it super heavy? Did it ever begin to sag even a little? We've been debating doing a cage style for the snakes as well, I know they aren't display or anything, but I like the idea of coming in from the side when I have to pick them up. So, if we go that route we'd make them stackable to save space. Of course, they're stuff won't be as big. I was thinking like... 34 x 24 x 10, and then section it off until they're bigger. P: But I'm still afraid of any sagging no matter the wood.

The post was very great, btw. A lot of the other stuff I read didn't put it in terms like you did with the sealants.
