Offering unobstructed views from your hot tub, Coast Spas’ Cascade Series comprises four vanishing edge models, each providing a practical and efficient solution to eliminating water displacement. Regardless of how many people are in the spa, the water level always stays the same. With no water spilling out of the tub, less chemicals are needed, helping to achieve a smaller environmental impact. Featuring the largest skimmers available, the Cascade series’ patented technology skims the water surface at a higher rate than competing models, keeping spa water free of debris. The vanishing edge design is also available for portable spas.
