The only thing you will need to do to the tub is make sure you have a good amount of air holes in it. Not so many that your loose all of your humidity, but enough for a good amount of air to flow in and out. I'm in Richmond too, nice to see someone local to the area on here. Good luck with your new friend, and p.s., once you have one, more will follow, so reconsider getting that rack! I just picked up another ball today!
