The AR-500 Premium by AquaRest Spas is a 5-person hot tub including a full-length lounger, patented LED backlit waterfall with 9 color settings, and 4 deep cup holders. Lay back in the body-conforming full-length lounger or captain's seats and enjoy the therapeutic benefits of the 29 two-tone stainless steel, multi-level jets powered by the 2hp/2speed upgraded Jacuzzi pump. Relax knowing that the AR-500 includes an ASTM-certified locking safety cover and full foam insulation, making it extremely energy efficient, and allowing it to meet the strict standards of the California Energy Commission (CEC). Keeping your spa clean is made easy with the patented Easy Kleen 100% water filtration and factory-installed AquaPure Ozone purifier, which can help reduce the use of harsh chemicals by up to 75%, saving you time and money! The AR-500 Premium AquaRest Spas is a 120v plug-n-play, roomy 5-person hot tub with a patented LED waterfall with 9 different color settings, 4 deep cup holders, digital controls, factory factory-installed AquaPure Ozone water purification system, and an upgraded stainless steel heater. The AR-500 Premium comes with a 120v 15-amp GFCI cord to just "Plug-n-Play", but you can also wire the premium version 240v, with the help of a certified electrician. Going 240v does increase the power of the heater, possibly resulting in even lower electric usage.

Free residential delivery and factory warranty are included.
