The LifeTrend Sierra dual temperature 3 person (2 person hot and 1 person cold) combo spa. Optimize recovery, boost circulation and relieve muscle tension and stress with temperature controlled therapy. That’s why we created the Sierra—the first all-in-one contrast therapy tub that lets you switch between hot and cold therapy in seconds. The Sierra is built for serious performance with a Balboa 1100W chiller maintaining your perfect cold plunge temperature, while a robust 4kW heater and 2HP jet pump ensure fast heat-up times and powerful massage action. Our advanced Joyonway touchscreen control system puts complete command at your fingertips, letting you easily adjust both hot and cold zones independently. The spa's intelligent design includes full-foam insulation on the cold side for maximum efficiency and traditional insulation on the hot side, plus convenient built-in drainage and a premium locking cover for hassle-free maintenance. Durable and ease of use, this system features a Magic Slice valve for smooth pump operation, ozonator water purification for cleaner soaking, and energy-efficient LED lighting to set the perfect mood. At 288 gallons capacity and 2,400 lbs when filled, this professional-grade unit requires 220V installation by a certified electrician but delivers unparalleled contrast therapy benefits in your own home. Whether you're an athlete seeking enhanced recovery, a busy professional needing stress relief, or simply someone who values premium wellness technology. All in one beautifully designed package that elevates your home wellness routine to spa-quality perfection.
