The natural rhythm of water can be found in the hypnotic cascade of a waterfall, a tranquil brook, and the exhilarating rush of rapids. The KOHLER® RiverBath whirlpool brings home these natural sounds and rhythms combined with mood-enhancing color light therapy. Rapids, whitewater, and whirlpool settings offer a full range of water massage treatments at the touch of a button-in a spacious 75" x 45" rectangular drop-in bath sized for multiple bathers.
