Jetted tubs use either air or water jets to create their soothing sensations, and because of that you can use bubble bath in both types of the tub, but you must do it with extra care to prevent an overflow of foam in your bathroom. However, keep in mind that while relaxing, the bubbles produced by air jets do not provide as much force or as deep of a massage as water jets. The water jets use a pump to pull in water from the bathtub, heat it and send it back into the tub under pressure. Water-jetted tubs provide an experience more akin to intense hydrotherapy. They require more intense cleaning than air jets, however, because they pull in dirty bathwater to create their jets.
