Cascade Series by Coast Spas

The Edge is the most compact Cascade Series spa available. Being smaller than its predecessors allows for installation in a broader range of environments. The new Edge sports a unique seating arrangement with a bench-style area that will accommodate a surprising amount of bathers, without feeling crowded. The two massage seats are designed to position the bather deep into the spa with jets aligned to target the back, neck, hips, hands and legs for a premium hydrotherapy experience.

In keeping with all other Cascade models, the Edge provides zero water displacement, keeping the water level consistently perfect. The Cascade IV has a sleek low profile that distinguishes it from other Cascade Series Spas, making it the right choice for a location with a 360 degree view. The Edge comes standard with a sheer descent waterfall which slightly overhangs the spa shell, allowing a soothing stream of water to drop directly into the hot tub. This creates a pleasing ambiance that will melt away your tension, providing the ultimate environment to relax and spend time with loved ones or socialize with friends.

A simple, elegant design that accentuates function and practicality while maintaining a size that can fit into any space. The Cascade IV has the Edge when it comes to being the most versatile negative edge spa we build.
