Bullfrog JetPaks® are the defining feature of the patented JetPak® Therapy System — the modular hydrotherapy design that sets Bullfrog Spas apart from traditional hot tubs. The JetPak® Therapy System is available exclusively in select Bullfrog hot tub and swim spa series.
If you’re exploring Bullfrog hot tubs or swim spas in Maine or New Hampshire, understanding how JetPaks work — and how they feel — will help you make a confident decision. At Skillful Home Recreation in Portland, Maine, we help homeowners across Southern Maine and New Hampshire personalize their spa seat-by-seat.
If you’re early in your research, our Bullfrog Spa Buyer’s Guide walks through the key decisions involved in choosing the right spa.

What Is a JetPak?
A JetPak is a removable, interchangeable back therapy module that fits into a specific seat inside a Bullfrog Spa.
Instead of permanently plumbing every jet into every seat — as most hot tubs do — Bullfrog engineered a modular system. Each JetPak contains its own targeted jet configuration and locks securely into place behind the seat.
This design allows you to:
• Customize massage styles by seat
• Mix different therapy types within the same spa
• Adjust or change configurations in the future
• Reduce internal plumbing complexity
JetPaks are available in:
• M-Series
• A-Series
• STIL Series
• CALM Series
• Swim Series (model dependent)
The X-Series uses a traditional fixed-jet design and does not include interchangeable JetPaks.
Why the JetPak System Is Different
Most hot tubs lock you into one jet configuration for the life of the spa.
With Bullfrog’s JetPak Therapy System, you choose how each seat feels.
That difference matters in three important ways:
1. Personalized Hydrotherapy
Not everyone wants the same intensity or massage style. One seat can deliver deep tissue pressure while another provides gentle, rolling relaxation.
2. Reduced Plumbing
Because water is routed more efficiently through the JetPak design, there are fewer internal plumbing lines. Fewer fittings mean fewer potential failure points over time.
3. Long-Term Flexibility
If your needs change — athletic recovery, stress relief, or comfort preferences — you’re not locked into a single configuration.
This is not just a feature. It is the engineering foundation of the Bullfrog Spa design.
The Real Advantage: Change the Massage — Not the Seat
One of the most distinctive aspects of the JetPak® Therapy System is how easily you can change your massage experience.
JetPaks are designed to be removed and swapped while the spa is filled. There’s no draining, no tools, and no complicated process — simply lift, reposition, and lock the new JetPak into place.
Most spa owners naturally gravitate toward a favorite seat — one that fits their height, depth preference, or recline angle perfectly.
Instead of giving up the seat that feels right, you can simply change the massage style within that seat.
Deep recovery one day. Gentle relaxation the next.
You don’t move seats — you change the JetPak.
That level of personalization is something traditional hot tubs simply don’t offer.
What Do Different JetPaks Feel Like?
Choosing a JetPak is less about technical specs and more about sensation.
Instead of comparing jet counts, think about the type of massage experience you prefer:
Deep & Therapeutic
Firm, penetrating massage for tight muscles, recovery, and people who genuinely want to feel the work.
Neck & Upper Body
Designed for people who carry tension high — focused relief for neck, shoulders, and upper back.
Rhythmic & Pulsing
Movement-based massage with kneading or pulsing action for those who prefer motion over steady pressure.
Everyday Comfort
Steady, full-back comfort for everyday unwinding without aggressive intensity.
Most homeowners naturally recognize themselves in one of these categories. That’s why understanding the differences between Bullfrog JetPaks — and experiencing them in person — matters more than comparing jet counts.
JetPak Compatibility by Series
Before reviewing individual JetPaks, it helps to understand compatibility.
Most JetPaks are compatible across the following hot tub series, with some exceptions:
• M-Series
• A-Series
• STIL Series
• CALM Series
Swim Series compatibility varies by model.
The X-Series does not use interchangeable JetPaks.
If you’ve already selected your spa series, we can confirm which JetPaks are available for your specific model and seating layout.
