The graceful hourglass design of this tub with a center drain provides plenty of room to soak or to enjoy hydro-massage. The design of this bath offers two backrest relaxation positions and an unobstructed path to fully stretch and immerse yourself. Bring the natural motions of air and water together with a combination system. Allow both the air bubbles and water jets to simultaneously massage the stress from your body. These systems also operate separately via touch control providing you with the flexibility to personalize your bathing experience.
