For me: Therapeutic uses only. For bathing purposes, they're a waste of time and water, and most bathtubs I've seen seem to be designed for people 5ft tall or less. The exception is when I've got one of my brutal, horrible, "I wish this was so tame as to be one of those headaches that makes you wish you were dead" headaches, or when I've ignored my RTS long enough that my arms are literally unusable.
