The owner of a 21-ft Catalina dual-temp swim spa wrote in 2026 (a BBB review shown on Birdeye) that the first spa was defective and was replaced, and praised the service technicians, a responsive sales team and customer service that answered calls. One owner's account; LPI replied publicly.

In a December 2018 forum thread, two long-time regulars said dealers they knew had stopped selling Catalina swim spas after LPI bought the brand, one citing leaks and frequent quality-control problems. Secondhand, from forum regulars rather than owners (one describes seeing LPI's wholesale prices at a trade show), and years before the current spec sheets.

Owner reports as of September 2026.

What LPI is known for

What salespeople lead with, checked against LPI’s own documents and public records. Of these eight, six are partly true and two are mostly marketing.

Partly trueOnly LPI'The Original Swim Spa', since 1980Catalina calls itself 'The Original Swim Spa' and says it introduced the first swim spa in 1980; the mark is…The catch: The first swim spa was Curtis's, and today's Catalina is built by LPI

The pitchCatalina calls itself 'The Original Swim Spa' and says it introduced the first swim spa in 1980; the mark is printed on its current spec sheets.

Our takeCatalina has a long swim spa history, but its own About page says the first swim spa was built by Curtis Swim Spas, which Catalina bought in 1985. The Catalina sold today is an LPI brand built in Tennessee since LPI bought it in 2016.

Who else has it: No other brand we researched claims to have invented the swim spa.

The catchThe first swim spa was Curtis's, and today's Catalina is built by LPI. Catalina's own About page credits the first swim spa to Curtis Swim Spas, bought by Catalina in 1985, and dates Catalina to 1977. LPI bought Catalina in November 2016 and moved production from Perris, California to Tennessee; its CEO said in 2017 it kept Catalina's designs but would trim the range.

Partly trueFew othersFactory-direct prices, thousands off MSRPLPI sells Catalina and Dr. Wellness swim spas in its own Whisper Outdoor stores and says selling…The catch: Every model was a third off MSRP on LPI's own store pages

The pitchLPI sells Catalina and Dr. Wellness swim spas in its own Whisper Outdoor stores and says selling factory-direct removes dealer markups of 30 to 50 percent; every store page shows a big saving against MSRP.

Our takeSkipping a dealer can lower the price, but the saving is measured against an MSRP LPI sets itself. On September 27, 2026 every one of the 45 swim spas in LPI's store was priced 33.3 to 36.8 percent under that MSRP for cash (26.3 to 30.0 percent financed). Compare real prices across brands, not the 'savings'.

Who else has it: Few swim spa makers own a national store chain; most sell through independent dealers.

The catch, partlyEvery model was a third off MSRP on LPI's own store pages. The store was running a 'Red Tag Clearance Sale' ending October 5, so prices move, but the uniform 33-37 percent gap suggests the MSRP isn't a useful benchmark. LPI's sister brand Pinnacle lists the 21' Marathon Dual Temp at $30,999 against Catalina's $52,499 MSRP.

Partly trueFew othersSwim, soak and cold-plunge in one cabinetThe Tri-Therapy (also listed as C-430 Marathon 21 Tri-Temp) puts a swim lane, a four-seat hot tub and a…

The pitchThe Tri-Therapy (also listed as C-430 Marathon 21 Tri-Temp) puts a swim lane, a four-seat hot tub and a one-seat cold tub with its own chiller in a 21-ft cabinet.

Offered on: Tri-Therapy (C-430)

Our takeThe three zones are real on the sheet, but the cold tub is small (90 gallons, one seat), and the model isn't on the Catalina Swim Spas site; LPI publishes no weights, heater rating, pump layout or warranty terms for it.

Who else has it: No other swim spa brand we researched has a built-in cold-plunge zone.

Partly trueFew othersAnyTemp: heat or chill the waterLPI's AnyTemp Hot and Cold Spa System combines a heater and a water chiller so the spa can be cooled as well…

The pitchLPI's AnyTemp Hot and Cold Spa System combines a heater and a water chiller so the spa can be cooled as well as heated, which LPI pitches for hot climates.

Our takeIt's an extra-cost upgrade on every Catalina model, not standard, and LPI publishes no cooling capacity, energy use or price for it. LPI owns a 2010 patent for a spa with a water-chilling assembly (US 7,712,161, assigned to LPI in 2019).

Who else has it: Cooling is uncommon on swim spas; the other brands we researched that offer it do so with optional or add-on heat pumps (Master Spas' Temp+Control and PDC's TempLock, for example) rather than a heater-plus-chiller package.

Mostly marketingOnly LPIHeat Flow Manifolds: 'free' heat from the plumbingLPI says its patented Heat Flow Manifolds, standard in its swim spas, warm the water by friction as it flows…The catch: No energy data, and a 2020 efficiency settlement

The pitchLPI says its patented Heat Flow Manifolds, standard in its swim spas, warm the water by friction as it flows, supporting the temperature and cutting heater use.

Offered on: LPI's store says every swim spa has it; only the dual-temp and Tri-Therapy sheets list it as standard

Our takeThe patent describes teeth inside the manifold that create friction while the pumps run and calls the result 'free' heat, but that heat comes from electricity the pumps draw. LPI publishes no measured saving, and its own pages disagree on whether the design is patented or 'patent-pending'.

Who else has it: LPI holds the patent (US 9,795,533, 'Hot tub manifold with raised frictional sections').

The catchNo energy data, and a 2020 efficiency settlement. LPI gives no standby-power figures for any swim spa, and we found no LPI listing in California's efficiency database. In 2020 LPI settled with California for $77,000 over spas sold there in 2016-2019 that missed the efficiency standard or weren't certified (no models named).

Partly trueFew othersInground-ready versions of seven familiesSeven of the 13 Catalina families come in 'inground' versions built to sit 24 in below grade, with the lower…

The pitchSeven of the 13 Catalina families come in 'inground' versions built to sit 24 in below grade, with the lower half of the frame in pressure-treated wood wrapped in polyethylene.

Offered on: Freestyle, Monterey, 16'-18' Catalina, 18'-20' dual-temps, 16'-18' Pool and 21' Pool families

Our takeA purpose-built inground model is a real option for a flush install, but its cabinet is 13 to 26 in longer than the portable version (except on the 21' Pool), the lower frame is wood below grade, and LPI's manual says making the spa accessible for service isn't covered by the warranty.

Who else has it: Most makers only allow recessed installs; Catalina sells dedicated inground models.

Partly trueFew othersBuilt in Tennessee, serviced by the factoryLPI builds its swim spas in Johnson City, Tennessee and supports them through its own stores and in-house…The catch: 20 technicians for five product lines across the country

The pitchLPI builds its swim spas in Johnson City, Tennessee and supports them through its own stores and in-house, factory-trained technicians rather than independent dealers.

Our takeThe plants and store chain are real (two Johnson City plants over 444,000 sq ft; 90 to 100+ stores), but LPI's July 2026 article counts 20 in-house technicians for hot tubs, swim spas, golf carts, UTVs and boats nationwide.

Who else has it: A maker-owned store and service network is unusual; most brands rely on independent dealers.

The catch20 technicians for five product lines across the country. LPI says its technician team grew from 8 to 20; ask where the nearest technician is based and who else services the brand locally. The BBB profile for LPI's parent company logged 101 complaints in three years across all its brands (as of September 23, 2026), and a 2026 owner review describes a 21-ft dual-temp swim spa that had to be replaced.

Mostly marketingFew othersDr. Wellness: designed with doctorsLPI markets Dr. Wellness as designed with input from board-certified doctors and 'the #1 most prescribed hot…The catch: Rebadged 2018 designs, and the E-8 has no swim current

The pitchLPI markets Dr. Wellness as designed with input from board-certified doctors and 'the #1 most prescribed hot tub line worldwide', and sells the S-12, S-16 and E-8 swim spas under that name.

Offered on: Dr. Wellness S-12, S-16, E-8

Our takeLPI names no doctors and gives no evidence for the 'most prescribed' claim, which is about hot tubs. The S-12 and S-16 layout pages are titled '2018 Signature Spa 12FT Swim' and '2018 Signature Spa 16 FT Swim', designs from LPI's Signature Spas brand.

Who else has it: Doctor-input branding is unusual, though the claim is made for the hot tub line.

The catchRebadged 2018 designs, and the E-8 has no swim current. The S-12 and S-16 layout pages are titled '2018 Signature Spa 12FT Swim' and '2018 Signature Spa 16 FT Swim', designs from LPI's Signature Spas brand. The E-8 is a 92 1/2 in square tub with no swim current.

Swim currentTwo or three 'river jets' (four on the Tri-Therapy), on most models fed by the seat…Partly

Catalina makes its current with 'river jets': two on 2- and 3-pump single-zone models and three on 4-pump models and every dual-temp, fed through diverters by the same jet pumps that serve the seats. The C-620 and C-621 dual-temps are the exception, with swim pumps shown feeding only the river jets. The Newporter, Malibu, Monterey and Marathon 18' and 20' sheets call the jets 8-inch and the C-630's lists the same part; the other sheets don't name the fitting. LPI publishes no flow, current width, top speed or air figures. Speed control is one two-speed pump plus single-speed ones, and Balboa's SmartSwim upgrade isn't offered on 4-pump models. Ask to see one run at full speed.

Applies to: All 41 Catalina codes, the Tri-Therapy (4 river jets, no layout published) and the Dr. Wellness S-12 and S-16; the Dr. Wellness E-8 has no swim current.

Room to swimLPI doesn't publish this. Ask the dealerNot published

LPI gives outside sizes only: from 150 in (S-12) to 250 in (Tri-Therapy) long, 87 to 92 1/2 in wide and 45 to 66 1/2 in tall (the E-8 is a 92 1/2 in square). Seats take one end of every single-zone model and a spa section takes the far end of the dual-temps, and no model has a published open swim length or water depth. The Pool 800 Series is sold as '62″ High', but that's the cabinet, not the water.

Applies to: All 45 models.

Frame and shellFiberglass-backed acrylic over an ABS base on the dual-temp models; frame material…Partly

LPI's dual-temp and Tri-Therapy sheets list 'Multi-Layered Fiberglass Reinforcement' and 'ABS Bottom Protection', and the Dr. Wellness sheets list multi-layer glass reinforcement, but the single-zone Catalina sheets say nothing about shell backing, frame or base. The only frame detail LPI gives is that the lower half of an inground model's frame is pressure-treated wood wrapped in polyethylene. Structure is warranted 10 years, but no warranty document says what that covers.

Applies to: All Catalina models (detail varies by sheet); Dr. Wellness S-12, S-16, E-8.

What this means, and how to check it →whisperoutdoor.com ↗catalinaswimspas.com ↗

Site prepLPI asks for a 6-8 in steel-reinforced concrete pad and a 60 A, 240 V circuit (two…Partly

LPI's manual calls for a level concrete pad 6 to 8 in thick, reinforced with steel and 8 in larger than the spa, footings below the frost line where ground shifts, no shims, and spreader bars whenever a swim spa is craned. The 2025-26 sheets call for 60 A on every single-zone model code and two circuits on the dual-temps, while LPI's 2023 website lists 50 A for many of the same codes, so have your electrician work from the sheet for your exact model code. Swim spa filled weights run from 13,575 lb (12.6-ft Newporter and Malibu) to 32,750 lb (21' Pool); the E-8 is 9,723 lb.

Applies to: All models; figures per code are in the model files.

Running costLPI doesn't publish this. Ask the dealerNot published

LPI gives no standby-energy figures, and we found no LPI listing in California's efficiency database. In 2020 LPI settled with California for $77,000 over spas sold there from 2016 to 2019 that didn't meet the efficiency standard or weren't certified, without naming models. Catalina sheets don't say what insulation is standard ('Extreme Foam Insulation' is an upgrade), while Dr. Wellness lists full foam. The patented Heat Flow Manifold and the AnyTemp heat-and-chill upgrade come with no energy data.

Applies to: All models.

Dual zoneSix dual-temp models, each side with its own pack and 4 kW heater; the Tri-Therapy…Yes

The 16' C-630, 18' and 20' Marathon (C-410, C-411), 21' Marathon (C-420) and 18' and 20' Catalina Dual Temp (C-620, C-621) each run the swim side and a 4- or 6-seat spa side on separate Balboa packs with their own 4 kW heater, touch panel and 100 sq ft of filtration. That doubles the equipment and the circuits: two 240 V supplies, 60 A plus 50 or 60 A depending on which LPI document you read. The Tri-Therapy adds a 90-gallon, one-seat cold tub with a 120 V 1 HP chiller on a third supply.

Applies to: C-410, C-411, C-420, C-620, C-621, C-630 and the Tri-Therapy (C-430).

What this means, and how to check it →whisperoutdoor.com ↗whisperoutdoor.com ↗

Service accessOrdinary jet pumps and Balboa controls behind a marked equipment end; LPI asks for…Yes

LPI's layout sheets mark the equipment access area: the seat end on most models, both ends on the 21' Pool and several inground model codes, and the long side plus the spa end on dual-temps. Its manual asks for 24 in of clearance on that side, 18 in elsewhere and removable deck panels on all four sides. The current runs on standard jet pumps rather than a hydraulic drive, and slice valves let a technician isolate equipment without draining. The manual also says making the spa accessible for service isn't covered by the warranty, and the pack is an LPI-coded Balboa unit ('LPIBP20').

Applies to: All Catalina models; Dr. Wellness layouts mark the equipment side too.

What this means, and how to check it →whisperoutdoor.com ↗catalinaswimspas.com ↗

Warranty terms10 years on structure and 5 on shell, parts and plumbing, but labor stops at 18…Partly

The only warranty LPI publishes for its swim spas is a one-line summary on each spec sheet; nothing says what 'structure' covers, who pays travel or removal, or whether coverage transfers, and the 21' Pool and Tri-Therapy sheets carry no terms at all. LPI's own pages disagree on Dr. Wellness: the S-12 and S-16 sheets say 10 years on structure, while LPI's store blog and comparison page say 5. The manual excludes damage from installation, electrical work, cranes and site preparation, and access costs.

Applies to: All models (Dr. Wellness terms differ; 21' Pool and Tri-Therapy unpublished).

What this means, and how to check it →whisperoutdoor.com ↗whisperoutdoor.com ↗

Cover and lifterAn insulated locking cover is standard on Catalina models, but LPI gives no…Partly

Catalina's Pro-Fit cover is marine-grade vinyl over a 1.25 lb foam insert with a 20-gauge steel frame and locks on the skirt; LPI doesn't say how thick it is, how many sections it has, or which cover any energy test used. No cover lifter is listed as standard or optional for the swim spas. The Dr. Wellness S-12 and S-16 sheets list no cover, and the E-8 comes with a locking hard cover.

Applies to: Catalina models (all list an insulated cover); Dr. Wellness varies.

LPI builds its spas in two Johnson City, Tennessee plants and sells Catalina swim spas factory-direct through its Whisper Outdoor stores (formerly Aqua Living), which handle warranty claims in-house. Its own July 2026 article counts 20 in-house technicians, up from 8, now covering hot tubs, swim spas, golf carts, UTVs and boats nationwide, so ask who would come to you and from how far. The BBB profile for LPI's parent company logged 101 complaints in three years across all its brands (as of September 2026).
