This Underscore bath offers both a relaxing whirlpool hydromassage and a blissful BubbleMassage experience, with separate keypads to control each independently. Eight adjustable whirlpool jets deliver a powerful hydromassage, while a built-in heater keeps the water at your desired temperature. With BubbleMassage, 122 air jets push air through the water, completely surrounding your body in a blissful cushion of massaging bubbles. The air jets can be targeted to a specific area of your body, or released throughout the bath for an all-over, tension-relieving massage.
