I recently purchased a Tank kind of thingy; it has a bung hole that can be unplugged for draining. The reason for this purchase is that our bathtub doesn't have the capacity to fill up satisfactorily, and I long to submerge my entire body in water with Epsom salts. I wanted the water to reach as high as my neck. The only way to do this is to fill this galvanized metal tank in the basement. We have a drain right in the floor so I can drain it there.
