See what our customers are saying

A great pool alternative

"My husband and I debated whether to put in a pool but decided that we didn't want to wreck a large part of the yard in order to do so. Also, the swim spa is practical to use yearround, unlike an in-ground pool."

— Glenna, California

Relief from my pain

"I had back surgery and needed a low-impact workout and a way to strengthen my core. I’ve lost weight, and my back feels better! Plus the jets help massage my back. I’m definitely motivated to work out!"

— Korinne, Texas

Low-impact exercise

"I truly enjoy swimming, stretching, walking against the current, and using the exercise equipment that came with the spa in a much lower-impact environment than at the gym."

— Leah, Texas
