I want to start off by clarifying my animals are happy and healthy in their existing enclosures, we have a variety of styles.

A dream of mine is to build some sizeable bioactive displays for my reptiles. We keep mostly ball pythons but have a few colubrids and arid lizards as well. I have considered buying pre-made, but we have the tools and skills to build and I think it would be really satisfying to look at it finished and know my partner and I built that. As I have begun the deep dive of research, I see a lot of people prefer PVC. I see a few concerns about warping but overall it seems to be the popular choice right now. Unfortunately, I haven't been able to find anywhere to buy 1/2" sheets for any price, much less an affordable one.

I don't have the skills or tools to work with glass outside cutting flat sheets to use as doors. That, to my understanding, leaves wood. I read a lot about it not holding humidity as well but then a lot of people list what sealants they use. What I have not seen is how well those sealants have held up between heat, humidity, urates, etc.

I'd love to know if anyone has experience and can talk about the pros and cons of their build.

I am looking to build something that will last a long time. If I am going to be replacing it in a few years, I'd rather save and invest in something pre-built.

If anyone knows an affordable place in Washington State (ideally eastern) to get PVC in 48"x96"x0.5" sheets, I would love to know that as well!
