Just about anything that would hold water and your snake would work. Just make sure the water is about half the depth of your snake so he doesnt have to swim and make sure you are watching while soaking. I use my QT tank when its not in use 10 Gal and put about 1/2-3/4 of an in of water in it. Set them temp to about 82f and let your snake soak in it. You could also add a small hand towel or cloth for the snake to crawl on if desired
