The award-winning Sundance Spas Optima will beautify your backyard, with AquaTerrace waterfall and SunGlow LED lighting that cycles through a color palette. This 7 person hot tub is our #1 best seller. Silent Air injector jets create tiny bubbles of aromatherapy when you add SunScents fragrance beads. A cascading AquaTerrace waterfall, and massaging jets from the reflexology foot dome, the Optima brings the Sundance spa lifestyle to your backyard. And though a 7 person spa, the Optima is surprisingly energy efficient.
