I think if you offer a large shallow pool with a few layers of paper towel, they'll be just fine. Just make sure to add lots of cover with plants, and maybe a background. I think my guy seems pretty comfortable actually lol. I have a three layers, and it's more then enough for comfort in my opinion. Let's keep in mind these are wild animals, and don't know what "comfort" even is...I can't see keeping them on paper towels detrimental to their health in the slightest. They don't have knobby elbows, and have a fat belly to keep them comfy haha. I personally think it's a good idea, and is working great for me.
