Streamlined for simplicity, the Underscore air bath exudes refined style with contemporary flair that fits with a variety of decors. Airjets release thousands of bubbles to massage your body at the level of intensity you prefer, helping to center your mind and release tension in your muscles. With the Zones of Control feature, the bubbles can be targeted to a specific area of your body, or released throughout the bath for an all-over massage. A slotted overflow drain allows full immersion for a deep, restful bath.
