Hi Gheezy, it is a composting toilet. Specifically it is a BIOLAN Composting ECO Toilet. I don't know about it being on Amazon or not, we ordered it from canadianecoproducts.com. Hope this helps and we would love an update if you move ahead with the bathroom. :)
@@gheezymarro8755 Thank you Gheezy! We highly recommend it, especially since you spend so much time outside. The washroom even allowed us to have a backyard campout without needing to go inside the house, which made it feel much more like real camping.
