In The Swim was founded in 1982 by a husband and wife team. Shipping chlorine from the back of their garage and taking orders on their front porch, they began to have a vision that this could be something big.
40 years later, In The Swim remains one of the country's largest online retailers for pool chemicals, supplies and equipment. Thanks for shopping with us!
