The Endless Pools E-550 exemplifies a disciplined, user-centered design approach. In contrast to conventional swim spa layouts, the E-550 employs a simplified and highly efficient configuration that increases the effective size of the swim basin by relocating the entry points to the front corners and fully integrating the seating into the overall architecture. This strategic reconfiguration eliminates unnecessary rear geometry, increasing interior volume and reducing disruptive backflow within the swim zone.

The expanded layout provides swimmers with a larger, unobstructed kicking area, preventing contact with steps and improving overall performance. Additionally, the flat rear wall enables a more effective push-off, while vertical resting zones with integrated hydrotherapy support recovery without compromising the swim experience. Together, these design decisions deliver a more refined, functional, and performance-driven product.
