As a contact, I thought about reaching out to a bath tub installation company to ask what type of bathtub they provided that consumes the least amount of water and to see if this idea is at all possible. In order to get the tub at different angles, it would probably have to be remote controlled similarly to the remote controlled angled beds. This might be a silly thought but I wonder if this would be safe considering the interaction between water and electricity.
