Introducing The Most Intelligent Salt System on the Planet.
FreshWater IQ is an in-line self-monitoring salt system that tells you what it needs to maintain clean, natural-feeling water, with less time and effort. Because we believe your hot tub should take care of you, not the other way around.
FreshWater IQ uses the FreshWater Salt System to generate the perfect amount of chlorine. With fewer chemicals, water feels softer and gentler on eyes and skin, and can stay clean and fresh for up to a full year*, conserving water and saving money.
Coast Spas™ have over 20 years of experience crafting the World’s Best Built Spas. Our mission is to deliver the highest quality spas with exceptional performance to customers worldwide.
