The black waves liner is a replacement part for SaluSpa Hollywood AirJet Hot Tubs. This outer liner is compatible with your AirJet hot tub, with 140 jets around the bottom of the tub that will surround you with a relaxing bubble massage. The semi-transparent liner creates an illuminated pattern on the outside letting the color-changing LED light shine through. The sturdy Tritech liner is made out of an ultra-durable, 3-layer material that is reinforced for strength and puncture resistance. Simply attach your filter pump, inflate the liner and enjoy a relaxing soak. Note: LED light not included. The replacement LED light (1A60P0551321) is sold separately.
