About Us

Atera AnyTemp® Spas, Swim Spas and Hot Tubs are manufactured in Phoenix, Arizona, U.S.A., by a team of industry veterans. The company's mission includes handcrafting, with only high quality North American components, exclusively featured, year round, fun and therapeutic health and wellness spas and swim spas in America.

After decades of listening to clients complain about their swimming pools being too cold most of the year to use and their hot tubs being too hot in the summer to enjoy, Atera AnyTemp® Spas set out to fill the large existing demand for a year round, indoor or outdoor, perfect temperature fun healing water experience.

After several years of research and development, in 120°F heat and below freezing temperatures, AnyTemp® Technology was invented and perfected in 2005.

The "Original" CTS8 AnyTemp® Spa model achieved an ambient air to water variance minimum of 30°F in 120°F heat and humidity with a low temperature setting of 62°F. The inventor and president filed a U.S. Patent Application in 2006, which was allowed in February, 2010.

This innovation quickly changed everything and now provides thousands of Americans each year with an economical, perfect temperature daily aquatic experience. For outdoor family fun, relaxation and recreation, aquatic exercise, swimming, hydrotherapy, training and rehabilitation in any climate, there’s finally an affordable and logical option.

For 2016 Atera AnyTemp® Spas, Swim Spas, Dual AnyTemp® Contrasting True Zone® Swim Spas and Hot Tubs offer 18 different models in 56 different configurations, all featuring exclusive Full Cycle® Therapy and all hand crafted in America.

The family founders have also owned a brick and mortar store in Glendale, Arizona, since 1996.
