The spacious McKinley® spa offers room for up to seven adults. Delivering total relaxation and value, its classic hydrotherapy experience makes you feel good long after leaving the water. Throughout this 680™ Series spa, configurations and jet formations soothe muscles and release knots to renew your body. A cool-down seat makes it easy to soak and socialize without completely leaving the water’s comforting warmth. And, thanks to classic jets nestled into a foot dome, your feet can find relief from almost any seat in the spa. Hot tubs in the 680™ Collection are available with an optional alternative insulation system. The right insulation can help to retain and regulate the temperature within your spa, creating a better-quality and more energy-efficient hot tub experience for years to come.
