EnergySave™ means Energy Efficient Most Energy Efficient means Lowest Cost to Own

Energy Efficient Spas and Hot Tubs

Bullfrog Spas are the most energy efficient spas in the world. The “EnergySave” design insulates the spa completely to prevent heat escape. With JetPak® technology, heat is recycled in the spa because the plumbing stays immersed in the hot water. Every single Bullfrog Spa model meets or exceeds the stringent energy guidelines of 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.


Bullfrog Spas are different. Up to 90% of the plumbing is on the JetPak, submerged in the hot water so any heat from water in the plumbing transfers to the spa water rather than being lost to the cold outside environment. Bullfrog Spas also recycle energy by using warm air from the equipment compartment to help to heat the water in the spa, rather than using cold outside air, as is the case with many other spas. These unique energy-saving features will keep monthly power bills surprisingly low and will keep you relaxed and worry free!


Bullfrog Spa

Conventional Spa

Bullfrog Spa with less plumbing and more power

Heat from JetPak plumbing transfers directly into the hot spa water, recycling energy. Bullfrog Spas are fully foam insulated.


conventional spa

Heat from plumbing escapes under the spa and is wasted. This spa has no foam insulation.


The WellSpring Water Management System1 - WellSpring Circulation Pump

Bullfrog Spa's WellSpring Filtration Pump lets you filter your spa water without the noise or high costs. TheWellSpring Filtration Pump is a quiet and vibration-free circulation pump that is more than 8 times as effective at filtering spa water than standard circulation pumps. Moving an astonishing 35 gallons (130 liters) per minute, this pump can push every ounce of water through the dual filters in excess of 160 times per day. The more times your water goes through the filter, the cleaner your water.

The primary benefits of the WellSpring circulation pump include:

  • Ultra-high energy efficiency
  • Virtually silent and vibration-free operation
  • Improved filtration
  • Increased jet performance

2 - 100 Percent Filtration

Bullfrog Spas' unique plumbing design allows 100 percent of the spa water to be filtered during the filtration cycles.

3 - WellSpring Standard- and High-Output Ozone Purifiers

Colorless ozone gas is nature's way of providing one of the strongest disinfectants in the world with 3,000 times the germ-killing power of chlorine. Choose the WellSpring standard- or high-output ozone purifier to maintain a sparkling fresh spa with reduced maintenance and lower chemical costs.

4 - WellSpring Heater

The WellSpring heater uses patented M7T temperature and flow sensor technology for increased reliability and performance. The Smart Sensor technology monitors and regulates water flow and temperature to ensure a proper operating environment for the heating element.

5 - 100 Percent Circulation

The water behind each JetPakT is circulated each time any pump is activated, keeping the entire spa fresh and clean.

Spa Construction

Bullfrog Spas' exclusive UniSystemT structural design is the future of advanced-spa
engineering providing world-class spa construction with superior strength and durability.

The WellSpring Water Management System

1 - UniBaseT

A great foundation is the basis for the best-designed and weather-proof spas. Our molded ABS base provides remarkable noise reduction, anti-vibration control, three convenient electrical chaseways, and a retractable exterior drain. The synthetic materials yield greater longevity compared to wood.

2 - UniFrameT

Bullfrog's injection-molded Z-Beam components connect the base, shell and cabinet to form an integrated framing structure with unmatched precision and strength. The UniFrame design ensures consistency in the manufacturing process and, along with the UniBase, delivers a superior foundation.

3 - UniColumnT

We add foundation supports under high-usage areas to strengthen overall spa integrity. This process greatly improves the structure of the footwell and seating areas of the spa.

4 - UniShellT

Our shell incorporates a bonded three-layer system for added strength and stability. We co-extrude a UV-stabilized acrylic surface to a layer of impact-resistant ABS. Isotec® high-density rigidizer is then applied enabling the shell to withstand the effects of time.

5 - EternaWoodT Cabinet

We use weather- and UV-resistant materials that are textured with a wood-grain pattern to offer years of maintenance-free enjoyment.

The only Hot Tub with a Leak Proof Design

Bullfrog Spas are leak-proof and powerful

Leak Proof Hot Tub

The “LeakGuard” design of Bullfrog Spas with JetPak plumbing ensures that you remain relaxed, not aggravated or worrying about leaks in your hot tub. Bullfrog Spas have up to 90% less plumbing and fewer holes underneath the spa than traditional spas. If a JetPak does happen to develop a leak, the water will stay in the spa rather than escaping. Jets are fitted into removable JetPaks instead of being drilled into the spa shell. The hot tub remains free of holes and, consequently, watertight!
