The Spray'n Play S4 Series Water Slides: Our unique S4 Series of water slides offers a level of quality and performance not found elsewhere in the industry. The tower and supports are manufactured of stainless steel, the flume is a wide design with integral curve wall extensions, and the non-slip steps and platforms remain cool even in the heat of a summer afternoon. A variety of color combinations are available for the steel and fiberglass components, meeting virtually any theme requirement. Designed for the long term, our S4 Series slides are fabricated in such a manner as to allow expansion of the system as time and finances may allow. This thoughtfully engineered system allows a seamless combination of individual designs so that you can expand or enlarge your water slide offerings to accommodate ever-increasing numbers of participants. Amazingly, with the advanced design and quality material selection found in the S4 Series, these slides are competitively priced, providing an even greater investment value.
