Bullfrog Spas Design
  • How does Bullfrog do this? JETPAKS (interchangeable & removable back jet massagers that sit in the water).
  • 90% less plumbing. LESS PLUMBING = MORE POWERFUL JETS
  • LESS HOLES drilled in shell = STRONGER shell
  • Far fewer glue joints = less chances of a leak
  • No diverter valves. ALL jets work at the same time.
  • Customize your massage experience and put the JetPaks in the seats you love most. (deep tissue, soft/soothing, kneading, firm pressure).
  • 23 JetPaks in all.
  • Direct heat transfer into water
  • SAVES more money on your ELECTRICAL bill
  • Easy to service. FAR LESS MONEY TO REPAIR
A & R Series

Sport X Series

Next is the Base & Structure
Bullfrog:

Endurabase:
  • 100% wood free construction (NO rotting)
  • Precision injection molded plastic base and supports (greatly helps to prevent cracks and lasts much longer)
  • 100% accurate, 100% of the time
  • No expansion or contraction issues
  • Rodent resistant, thick ABS base (no animal nesting = no plumbing or electrical damage)
  • Built in electrical chase ways in base (easy installation)
  • Support columns under each seat / foot well (no flexing, no cracks)
Bullfrog Spas Insulation Step
  • Bullfrog uses R-45 insulation to help achieve the lowest energy usage in the industry according to the CEC (California Energy Commission)
  • 90% less plumbing with JetPak technology means that only a small percentage of the plumbing is sealed in the insulation

ALL Other Brands of Spas

ALL other hot tubs are designed like the picture above and this caused expensive repairs and shortness of spa ownership.

90% MORE plumbing(all in the foamed in cabinet) causing excess friction, less powerful massage, less energy efficient

  • Each jet has to have a hole drilled through the shell. Then sealed on both sides to prevent leaks. All these holes can structurally weaken the shell and cause cracks and leaks.
  • Each jet has 5 potential points for a plumbing leak(jet to shell, 2 plumbing to jet body, plumbing to manifold)
  • Jets cannot be moved into other seats or locations
  • Diverter valves added. Cuts off water to whole seats
  • ALL plumbing is sealed in foam (see video below)
  • VERY DIFFICULT to find a LEAK so it’s very EXPENSIVE to repair
  • All the plumbing directly HEATS the CABINET instead of the water
Traditional Built Hot Tubs

(Upside down view)

  • Wood 2×2, 2×3 or 2×4 construction (hand cut with chop saw, stapled together)
  • Wood expands and contracts (causes cracked shells)
  • Wood pieces are not cut to accurate lengths all the time, causing structural weaknesses.
  • Wood touches the ground and rots out over time. Weakens the frame and causes the shell to crack and water to leak out
  • No ABS base= rodent infestation, damaged plumbing/electrical, water intrusion & rot
Traditional Spray in Insulation Process

Watch the video.

  • This design ends up costing you much more in repairs and eventually forces you to have to buy a new hot tub in HALF the time than if you would have purchased a properly designed spa like a Bullfrog Spa.
