The gray wicker liner is a replacement part for SaluSpa Cancun AirJet Hot Tubs. This liner is compatible with your AirJet hot tub, with jets around the bottom of the tub that will surround you with a relaxing bubble massage. The sturdy Tritech liner is made out of an ultra-durable 3-layer material that is reinforced for strength and puncture-resistance. The liner features the patent-pending EnergySense insulation, making it as much as 40% more energy-efficient than similar inflatable hot tubs. Simply attach your filter pump, inflate the liner and enjoy a relaxing soak.
