The Most Energy Efficient Hot Tubs

Lower Cost to Own and Operate

Everyone says it, but data actually shows that Bullfrog Spa models are the most energy efficient hot tubs in their class.* You’ll save up to 59% on energy costs when compared to other spa brands.


Every single Bullfrog Spa model meets or exceeds the stringent energy guidelines of the California Energy Commission (CEC).


With the superior energy efficiency, you will enjoy keeping extra money each month almost as much as you will enjoy relaxing in your spa.


*Energy calculations based on data compiled by the California Energy Commission and US Energy Information Administration.

Engineering The Best Hot Tub

Less Plumbing =
Less Energy Loss

Because Bullfrog Spas are built with the patented JetPak Therapy System™, they utilize about 90% less plumbing than conventional hot tubs. Less plumbing equals less friction and less energy used to get water to the jets.


In addition, most of the water delivery system in a Bullfrog Spa is inside of the proprietary H2Air Manifold on the JetPak® and is submerged in the hot water.


Any heat from water in the JetPak manifold transfers directly to the spa water rather than being lost to the cold outside environment.

Full Foam Insulated Hot Tubs

Bullfrog Spas’ full foam design insulates the spa completely to prevent heat escape, even in the coldest climates.

Bullfrog Spas utilize an ultra energy-efficient foam throughout the interior of the spa structure to lock in more heat. Infrared heat mapping shows the difference that full foam insulation makes. A full foam insulated Bullfrog Spa locks in the heat and very little escapes to the outside air.


In a conventional hot tub you can see that more heat is lost to the outside environment, requiring the hot tub to use more energy to keep the water warm.
