The AquaRest AR-150 Standard packs a fully customizable massage powered by a 1.5hp Jacuzzi brand pump into a comfortable 4-person hot tub. 12 multi-level stainless steel jets provide pinpoint massages to different muscle groups, providing therapeutic and relaxing hydrotherapy. The AR-150 Standard is manufactured using state-of-the-art roto molding technology that produces a super durable and unbelievably portable hot tub, resistant to all weather types and weighing in at only 234 lbs. Your massage, your way, with therapeutic lumbar arch support alleviates achy backs and the multi-level jet placement delivers soothing water pressure that massages your muscles into relaxation. Take relaxation to a whole new level with a patented multi-color LED backlit cascading waterfall with 9 colorful light settings to help create just the right ambiance. Ease your mind knowing that your AR-150 Standard comes with an ASTM-certified locking safety cover, keeping the leaves and debris out of the heat inside of your hot tub, making it extremely energy efficient. Reduce your use of harsh chemicals with the AquaRest patented Easy Kleen 100% water filtration system, ensuring that all your water passes through the filtration system. Installation is a cinch with the 120-volt 15-amp plug-n-play setup, including a 12-foot GFCI cord. 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-150 Standard follows the "Simple, Portable, Durable, and Affordable" philosophy that has helped AquaRest spas become the #1 hot manufacturer online. Free residential delivery and factory warranty are included.
