Young Curly Brunette Girl Having A Shower And Posing In The Bathtub

A baby bathtub is one used for bathing infants, especially those not yet old enough to sit up on their own. These can be either a small, stand-alone bath that is filled with water from another source, or a device for supporting the baby that is placed in a standard bathtub. Both types are designed to allow the baby to recline while keeping its head out of the water.
Hot tubs
Hot tubs are common heated pools used for relaxation and sometimes for therapy. The "hippie" era (1950–1970) popularized them in America in songs and movies.
