The AR-500 Standard by AquaRest Spas is a 110v, 5-person hot tub including a full-length lounger, patented LED waterfall with 9 mood settings, 4 deep cup holders, and factory-installed AquaPure Ozone water purification system that will help reduce the use of harsh chemicals by up to 75%. Lay back in the body-conforming full-length lounger and enjoy the therapeutic benefits of the 29 two-tone stainless steel, multi-level jets powered by the 1.5hp 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). Save time and money keeping your spa clean with the patented Easy Kleen 100% filtration system and factory-installed AquaPure Ozone Water Purifier, which can help you reduce the need for harsh chemicals by up to 75%. Our standard hot tubs are heated by Friction Heat - when the motor is running it creates roughly 1KW of heat, combined from the friction created by the water rushing through the pump and plumbing provides adequate heating to increase the temperature by roughly 1°F per hour. The AR-500 Standard is a full-sized spa that follows the “Simple, Portable, Durable, and Affordable” philosophy that has helped AquaRest Spas become the #1 online hot tub manufacturer. Free residential delivery and factory warranty are included.
