SS - No tape. Got it. Though, I've seen people leave wood exposed in their builds, but they emphasize the varnishing/sealing part. The one I saw recommended a non-toxic varnish, which besides tung oil, I didn't know existed. But I can see where snake urine and wood might not be great companions.

You mentioned tile, which I thought of, pretty good material at transferring heat, that's what they pair in-floor heating with usually anyway. Could be a cozy alternative to glass on the bottom. I'll have to look into that more thoroughly. Thanks.
