Ready to experience the ultimate in spa luxury? Step into the Bel Air EC-851B. This roomy, 8ft spa is the perfect place to relax and unwind after a long day or host gatherings with friends. It comfortably seats six adults with inviting, bench-style seats. It also features a unique kool-off seat – a shallower seat that allows you to stay partially submerged in the spa.

The Bel Air EC-851B measures 7′9” x 7′9” x 40.5″ and boasts 51 total jets that are powered by a 2-pump system. The exclusive Velocity jets are positioned in such a way to target specific muscle groups and release tension right where you need it most. When you’re ready to switch up your massage, simply move to a new seat, as each one has unique jet configuration. And the jets are adjustable so you can fine-tune your massage.

In addition to an incredible hydromassage, you’ll enjoy the ambiance created by the beautiful curved cascade LED waterfall and perimeter LED lighting. Plus, the digital control panel allows you to quickly and easily adjust the settings of your spa’s jets, water temperature, lights, and more.

For maximum energy efficiency and heat retention, The Bel Air EC-851B features Cal Spas’ thermo-shield side panels filled with premium insulation. The wood cabinet frame is pressure-treated to resist rot, bugs, and decay. And the Bel Air is available in a variety of cabinet and shell colors so you can create a spa that matches your aesthetic.

Investing in total body wellness is easy with the Bel Air EC-851B. And for added confidence in your purchase, this spa comes with a 10-year structural warranty, 7-year finish warranty, and 5-year warranties on labor, cabinet, and parts.
