You can use any kind of wood that will hold up to the job, but I wouldn't use redwood or cedar. I've made several of them out of 1/2" exterior plywood. Because I use a moist substrate, I then lined the inside with sheet plastic.
Thank you. Do I need to put a waterproofing stain on the wood and will this be harmful to the tortoise? The enclosure will be in my family room so I would like to possibly use a hardwood. Is there anything I should stay away from?
I used a shower curtain for mine, but my Russian has put holes in the corners, just to give you a heads up. I just put a piece of wood in the corner, & when I change the substrate next I will just change it out.
I used garden paper my dad had laying around the house, though I only wrapped the bottom. I think I'm going to be building a new table in the next few weeks, perhaps I'll do a pictorial as I go.
