Hot and cool dials, temperature settings, joysticks - this machine was certainly more than just a simple bath.
"The blue one (which we also have), with all the knobs on the top of the column, is also a
regular bath tub, that lowers to allow the patient to step into the tub, and then the nurse's
aid/orderly is able to move the tub up to waist height, allowing the aid to bathe the patient
without putting strain on their back. The knobs on the far left are for the shower hose attachment,
the knobs in the middle are for filling the tub, and the joystick is used to move the tub up and down." - Kim.
There - a simple bath tub!
