The Avalon E-840L is a large, 8ft spa that delivers on style and performance. Perfect for friends and family gatherings, it comfortably seats 6 adults with 5 bench-style seats in addition to a full-size lounger. The Avalon EC-840L measures 7′9” x 7′9” x 40.5″ and boasts 40 jets powered by a 2-pump system.

Each seat in the Avalon EC-840L has a unique jet configuration. This allows you to switch up your hydromassage by simply moving to a new seat. The jets are also adjustable for added customization. The spacious footwell allows everyone to relax comfortably while enjoying time together in the spa. The Avalon EC-840L also features a beautiful curved cascade LED waterfall and perimeter LED lighting.

Like every Cal Spas hot tub, the Avalon EC-840L has thermo-shield side panels that are filled with premium insulation for maximum energy efficiency and heat retention. The wood cabinet frame is pressure-treated and resistant to decay, rot, and insects. The Avalon is available in a wide range of cabinet and shell colors to fit the aesthetic of your choice.

With the Avalon EC-840L, it’s easy to make the most of your outdoor living space while customizing your hot tub experience. The digital control panel allows you to easily adjust the jets, water temperature, lights, and more. This spa also comes with a 10-year structural warranty, 7-year finish warranty, and 5-year warranties on labor, cabinet, and parts for added confidence in your purchase.
