The pitchEach seat back is a removable JetPak holding its own jets; you pick from up to 16 massage styles when you buy, move them between seats without tools or draining, and add new ones later.
Offered on: M Series, A Series, STIL, Swim Series (not X Series or Calm)
Our takeThe tool-free swap is real and is the feature owners praise most in reviews on Bullfrog's site, but an extra JetPak costs about $875 at a dealer, one valve sets a whole seat rather than each jet, and NAD found Bullfrog could not support saying it offers more personalization than any rival.
Who else has it: No other brand sells removable jet seat modules. Bullfrog's first JetPak patent (US 7,908,684) expired in 2024, but a later one on its current modules (US 9,662,268) runs to 2034.
The catchAll the jets in a JetPak run off one valve, so a seat's pressure moves up or down together and you can't set individual jets. Bullfrog's 2026 A and M Series manuals (and its 2014 manual) name one valve in the lower part of each JetPak as the only flow control for that pack's jets; only the separate foot, hip, calf and wrist jets in the shell adjust one by one. The valve is also built never to close fully, so a seat can be turned down but not off; one owner-forum post says NeckMasseuse packs add a separate control for their neck jets.
The catchAdding or upgrading JetPaks later, the big selling point, costs $575 to $1,209 per pack. A single broken jet doesn't force a new pack, though: jets, valves and gaskets are sold on their own. The price is real: a Bullfrog dealer's parts store lists complete JetPaks at $575–$1,000 for 2023-on A Series, $604–$919 for 2013–2022 A and R Series and $751–$1,209 for M Series, all built to order. The same store sells single JetPak jets ($30–$82), the valve assembly and gaskets, so only damage to the JetPak body or manifold forces a whole new pack. Complete JetPak $575–$1,209, single JetPak jet $30–$82 (M Series jet inserts $33–$83), JetPak valve assembly $32, JetPak cap assembly $92.99, manifold gasket $9.99–$29.99

The pitchBullfrog builds its tubs in its own plants near Salt Lake City and says most of its parts come from U.S. suppliers.
Our takeThe Herriman, Utah plant is real, though Bullfrog's own wording is 'assembled in the USA', and its claim of above-average domestic sourcing comes with no figure.
Who else has it: Many brands build in the U.S., including Master Spas (Indiana), Cal Spas (California), Nordic (Michigan), PDC (Pennsylvania) and Hot Spring (California, plus a plant in Mexico).

The pitchBecause each JetPak carries its own jets and plugs into a manifold inside the water, Bullfrog says its tubs have far fewer holes, fittings and hoses, so less can leak, more pump power reaches the jets and less heat escapes. Its 2022 brochure put the cut at up to 90% less plumbing.
Offered on: M Series, A Series, STIL, Swim Series
Our takeLess under-shell plumbing is real by design. But after a Jacuzzi challenge, NAD found no support for Bullfrog's claims of more power and better efficiency than conventional tubs, and owners report leaks and buzzing at the JetPak gasket. Bullfrog's parts store now sells a newer version of that gasket for JetPaks made since 2017.
Who else has it: The in-water manifold layout comes with the patented JetPak design; conventional tubs run plumbing to each jet group under the shell.
The catchLess plumbing hasn't been shown to deliver more jet power or lower energy use than a conventional tub. After a Jacuzzi challenge, the advertising watchdog NAD found in January 2025 (case 7384) that Bullfrog had no reliable evidence its tubs are more powerful or more energy-efficient than conventional ones, and Bullfrog has never published a measurement behind its up-to-90%-less-plumbing figure.
The catchWith the plumbing inside the tub, water sits behind every seat, so you pull and scrub every JetPak at each drain. Bullfrog's manuals tell owners to remove all JetPaks at every water change (every 1–4 months) and clean the pod and manifold areas, and a rival Hot Spring dealer knocks the mildew that can build up there; the upside is that the area is easy to reach.
The catchAll the jets in a JetPak run off one valve, so a seat's pressure moves up or down together and you can't set individual jets.

The pitchEvery Bullfrog sits on a patented molded-plastic EnduraFrame with no wood or metal to rot or rust, and the JetPak lines carry a lifetime frame warranty.
Offered on: Frame: all series. Lifetime frame warranty: M Series, A Series, STIL, Swim Series.
Our takeABS will not rot, but NAD found no support for Bullfrog's claim that it outlasts wood or metal frames, and the lifetime term covers only the original owner on M, A, STIL and Swim models (5 years on X Series, 3 on Calm).
Who else has it: Rot-proof frames are common: Hot Spring's Highlife uses a polymer structure, and Vita Spa and American Whirlpool back steel frames for life.
The catchThe lifetime frame warranty becomes ship-it-to-Utah-at-your-cost after year seven, and it ends if you sell. Bullfrog's current M, A and STIL warranty says a structure or frame failure after seven years must be sent to Bullfrog for repair at the owner's expense, with the owner paying shipping and the cost of removing and reinstalling the spa; the warranty ends on any transfer of ownership, and if a company or trust bought the tub, 'lifetime' means ten years.

The pitchOptional audio uses transducers hidden in the shell, so the tub itself acts as the speaker, plus a built-in subwoofer and Bluetooth, with no speaker grilles to crack or fade.
Offered on: Optional on M Series, A Series, STIL and X Series (not Calm, which gets basic Bluetooth audio)
Our takeThe hidden design is real, but Bullfrog publishes no wattage or transducer count to back its sound-quality claims, and audio is warranted for only one year.
Who else has it: Artesian's Island Spas line also offers transducer audio; Jacuzzi, Caldera and Cal Spas use conventional speakers.

The pitchThe Simplicity filter is a flat panel set into the spa wall that spreads flow across its whole surface, so a smaller filter cleans well, frees room for seating and costs less to replace than bulky cartridges.
Offered on: M Series, A Series, Swim Series
Our takeThe design and patents are real, but Bullfrog publishes no filtration test, filter area or replacement price to back its performance and cost claims.
Who else has it: Bullfrog lists its own filter-system patents (for example US 10,518,202); most rivals use round cartridges, such as Hot Spring's Tri-X.
The catchThe flat filter is a frequent, genuine-parts-only consumable, and you pull a JetPak to reach it. Bullfrog's A and M Series manuals say to clean or replace the Simplicity filter every 4 weeks, replace it at least every 12–16 weeks and use only genuine Bullfrog filters to keep warranty protection, and the swap starts by removing the JetPak in front of the housing. Bullfrog's store sells a 4-pack for $79.99, about $20 a filter, so roughly $80–$240 a year depending on how often you replace. $79.99 per 4-pack (about $20 a filter)

The pitchThe top M Series comes with 4 to 7 JetPaks, a quiet circulation pump, EOS ozone that Bullfrog says makes up to three times the ozone of standard units, and a sensor cover that can send lid-open alerts to your phone.
Offered on: M6, M7, M8, M9
Our takeThe standard kit is real, but the ozone figure is Bullfrog's own, phone alerts need the optional Wi-Fi module, and in California energy filings M Series models use 91–97% of the standby power allowed, versus a 76% median for A Series listings.
Who else has it: Lid-open alerts from a sensor cover are unusual and patented (US 10,934,729); circulation pumps are standard on rivals' top lines too, such as Hot Spring Highlife and Caldera Utopia.
Other things to know1
The catch (partly true)Rivals say everything on a Bullfrog is proprietary, so only a Bullfrog dealer can keep it running. The control packs are standard Gecko in.yt and in.ye systems, and Bullfrog's own online store sells gaskets, headrests and filters to anyone; but that store (62 parts) lists no complete JetPaks, jets or JetPak valves, which come through dealer parts counters, and the warranty is void if anyone other than an authorized Bullfrog agent does a repair.
What rivals and critics say3
Jacuzzi argued that Bullfrog cannot back up its claims that its tubs are more personal, more powerful, more efficient and longer-lasting than conventional hot tubs.Our check: NAD agreed on all four in January 2025 (case 7384), and Bullfrog said it would comply while disagreeing with parts of the ruling; NAD judged the comparisons, not whether the features work.
JetPaks are a gimmick: they limit where jets can go, restrict flow and let dirty water collect behind them.Our check: Bullfrog itself tells owners to pull every JetPak and scrub behind it at each water change, and owners report gasket leaks and buzzing fixed with spacer rings and a newer gasket; the flow claim is unmeasured.
Bullfrog shells are thin and rest on a cradle instead of supporting themselves.Our check: Bullfrog confirms its plastic frame, not the shell, carries the water weight, which is common in the industry; we found no thickness data or teardown, and the shell structure is warranted for 10 years.

Swappable JetPaksThe most-praised feature in reviews on Bullfrog's own site: owners like tailoring each seat and moving or adding JetPaks later. 69 of 77 such reviews gave four or five stars.
Owners praise the massage41 reviews on Bullfrog's own site praise how the jets feel, all at four or five stars; the brand solicits and moderates those reviews.
Factory steps in when dealers stallOn an owner forum, a Bullfrog support account asks for serial numbers and takes cases offline, and regulars say calling the Utah office settles issues a slow dealer won't.
What they complain about
JetPak seals that leak or buzzOwners across model years describe the seal where a JetPak meets its port shifting, spraying water behind the seat or buzzing loudly; reported fixes include spacer rings and a newer gasket.
Service hinges on the local dealerThe most common complaint on independent sites: warranty work runs through the selling dealer, and owners describe unreturned calls, farmed-out repairs and being stranded when a dealer closes.
Delivery delays and damageOwners report long waits and tubs arriving with cracked corner panels, wrong or missing covers or loose control panels, mostly in 2020 and 2021 but also in 2026.

Cloudy water and filter costs A cluster of 2026 reviews on Bullfrog's own site say the filter struggles to keep water clear and replacement cartridges are costly.
What decides whether a tub lasts is mostly hidden under the shell. Here is what Bullfrog Spas publishes about it, and where it publishes nothing, we say so.
NoSelf-supporting shellA molded ABS frame carries the water weight, not the shell.
Not publishedClamped plumbingBullfrog Spas doesn't publish this. Ask the dealer to show you.
PartlyManifold-fed jetsEach seat feeds from a manifold, but seats may run in series.
How it's kept hotInsulation100% closed-cell full foam on every series, per Bullfrog; density and R-value not published.
NoSelf-supporting shell · Applies to: All series, which share the EnduraFrame structure and full-foam insulation
Bullfrog builds the structure into a separate ABS EnduraFrame with extra supports under high-use seats, then fully encases the acrylic shell in closed-cell foam. The shell warranty promises no leaks rather than structural integrity. Full foam also means a tech has to cut foam away to reach a plumbing leak.
Not publishedClamped plumbing · Applies to: All models
Bullfrog never says whether its joints are glued PVC or barbed fittings with clamps, and the manual only tells you to hand-tighten a leaking fitting. One outside site claims glued and clamped lines, with nothing to back it up. Ask a dealer to open the equipment bay and show you.
PartlyManifold-fed jets · Applies to: JetPak lines (M Series, A Series, STIL and Swim Series); plumbing on X Series and Calm is unknown
Every JetPak gasket seats into the H2Air manifold instead of splicing into a hose run, and the jets inside a pack feed off that manifold. Bullfrog's own older patent shows the seat manifolds chained one to the next along the supply line. Whether current tubs still do that is not published.
Boards, topside panels, pumps, motors, jets and filters are industry-standard parts any tech can buy. The JetPaks, the H2Air manifold and the frame are patented Bullfrog designs that independent retailers do not stock. Routine repairs stay cheap and easy, while anything JetPak-related goes back through the dealer.
PartlyCompression-fitted jets · Applies to: All series
Bullfrog's parts store sells shell jet bodies with nuts and gaskets for fixed-jet seats. A JetPak lifts out whole and seals to the shell with a gasket. How the jets attach inside the pack isn't published, and packs are sold only complete.
PartlyAdjustable jets · Applies to: A Series checked directly; other JetPak lines likely work the same. X Series and Calm not verified
Foot, hip, calf and wrist jets molded into the shell turn like normal jets. Inside a JetPak, one valve in the lower housing raises or lowers flow for that whole seat, and it will not shut off completely. So you get per-seat control, not per-jet control.
PartlyService network · Applies to: All models, North America
Bullfrog sells through authorized dealers and its own factory stores, and the manual sends every warranty issue to them. Manuals are published free and commodity parts are easy to source, which helps an independent tech. The proprietary JetPak and manifold parts are not widely stocked outside the network.

Founded in 1996 in Salt Lake City, Utah. Never sold; owned today by a private company.
In 1989 David Ludlow, a pool builder's son, came up with removable jetted seat backs that would hold the jets and most of the plumbing. He formally set up Bullfrog International in Salt Lake City in 1996; its first production spa had six JetPaks and two pumps.
