What Endless Pools is known for

Holds upFew othersPropeller current, not jetsEndless Pools moves water with a hydraulically driven propeller that pushes a broad, even current you can…2 catches

The pitchEndless Pools moves water with a hydraulically driven propeller that pushes a broad, even current you can swim against with normal strokes, instead of the narrow, bubbly stream jets make. Its top system claims 5,000 gallons a minute in a current 24 inches wide.

Offered on: E-Series swim spas and all modular pools with Hydrodrive; X-Series SwimCross and R-Series RecSport swim spas use airless jets instead.

Our takeEven jet makers concede a propeller gives a smoother, wider current, and Endless publishes real pace and flow specs. Its boast of beating every other swim current is unproven, since SwimEx makes the same boast, PDC claims a wider current, and all the figures are self-reported.

Who else has it: Most swim spas use jets; PDC Spas sells a propeller system (TruSwim, 29 inches wide, up to 5,000 gpm) and SwimEx uses a paddlewheel.

The catchThe propeller runs on hydraulics that need scheduled service, including a new underwater motor every six years. Endless' 2026 swim-spa manual calls for new hydraulic fluid and filter every 500 hours of use (about every 16 months at an hour a day) and, after six years, replacing the submerged swim-machine motor so the non-food-grade hydraulic fluid can't get into the water, while the swim-spa component warranty runs five years. Its modular-pool schedule warns that skipping the motor swap can leak hydraulic fluid into the pool.

The catchOnly the priciest E-Series swim spas get the propeller; SwimCross and RecSport models use jets. Endless says the E-Series are its only swim spas with Hydrodrive, while the X-Series uses four airless jets and the R-Series three, and the entry E500 starts at $55,999. E500 from $55,999 MSRP

The pitchModular pools ship in sections that fit through a standard doorway and down stairs, so a 7-by-14-foot swim pool can go in a basement, garage or sunroom, and handy owners can install it themselves.

Offered on: Modular pools (Original, Performance, Elite, Dual Propulsion, Streamline, WaterWell); swim spas ship assembled.

Our takeEndless documents sectional delivery and owner installation, and its base 7-by-14 pool lists at $33,999 before installation; swim spas, by contrast, arrive fully assembled and need an opening wider than 89 inches to go indoors.

Who else has it: SwimEx also sells compact freestanding current pools for indoor use, from $51,900; we found no other maker selling a sectional kit that owners can assemble.

The catchHandy owners can assemble the modular pool, but the warranty covers parts for only two years and steers installation to licensed pros. Endless' 2025 modular-pool warranty covers parts for two years (steel panels ten), never covers labor or freight, isn't transferable, recommends a qualified licensed professional for installation, voids the panel warranty without proper drainage and bonding, and excludes use with salt chlorine generators. Extended warranty $540 (must be bought within 30 days of purchase)

The catchA modular pool is a vinyl-lined steel box with wear parts: a new liner every 6–10 years and cover fabric every 5–7. Endless' own maintenance schedule for its Original Series and WaterWell pools lists liner replacement every 6–10 years and cover fabric every 5–7 years, plus filter cartridges every four months; rival SwimEx pitches its liner-free fiberglass pools against exactly this.

Holds upFew othersAdd a current to your poolThe Fastlane machine mounts on the deck or wall of an existing pool and gives it an endless swim lane with…1 catch

The pitchThe Fastlane machine mounts on the deck or wall of an existing pool and gives it an endless swim lane with the same propeller approach, while its hydraulic power unit can sit up to 200 feet away.

Offered on: Fastlane Swim (deck- or wall-mounted) for existing pools; Fastlane Tread for new or renovated pools.

Our takeIt is a real, patented propeller machine, but at $10,999 list before installation it costs much more than a Slipstream, and the unit stays visible above the water.

Who else has it: Fastlane's design is patented (US 7,526,820, in force until 2027). Slipstream, started by Endless Pools' own founder, sells a battery-powered machine for $5,495–$6,495, and jet units such as Badu serve recreational swimmers.

The catchThe $10,999 price is for the machine only. Endless' 2026 Fastlane price list excludes shipping and installation, includes only a 25-foot hydraulic hose (50 to 200 feet costs $300–$1,500 more) and charges $250 for an outdoor power-unit shield; the in-pool unit runs on a submerged hydraulic motor for which Endless publishes a replacement procedure. $10,999 plus $300–$1,500 for longer hoses, $250 outdoor shield, shipping and installation

The catchThe propeller runs on hydraulics that need scheduled service, including a new underwater motor every six years.

The pitchEndless offers an underwater treadmill set into the pool floor, so the same pool handles low-impact walking and running as well as swimming.

Offered on: Modular pools and E-Series swim spas

Our takeIt is a real option running 0.5 to 5.5 mph, but Endless calls it exclusive when rivals sell comparable treadmills, and it adds $14,999 to a modular pool.

Who else has it: SwimEx offers treadmills in its 500, 600 and 800 Series pools and HydroWorx builds treadmill therapy pools; Endless says Master Spas' Michael Phelps swim spas offer none.

The catchIn the swim spa the treadmill shares the swim current's hydraulic power, so the two compete. Endless' manual says top swim speed drops when the treadmill runs at its highest speeds, a slight current runs even with only the treadmill on, and the treadmill can pulse at its slowest settings; its motor and drive belt are due for replacement after six years, and on modular pools the treadmill is a $14,999 option. $14,999 option on modular pools

Partly trueFew othersThe original swim-in-place poolSalespeople tell the founder's story, a swim-in-place pool first built for Columbia University swimmers in…1 catch

The pitchSalespeople tell the founder's story, a swim-in-place pool first built for Columbia University swimmers in 1985 from an idea his father had in Arizona's irrigation canals, and note that USA Swimming now names Endless Pools its official swim spa supplier.

Our takeThe history is real (Endless' first pool patent was filed in 1989), but the USA Swimming deal is a sponsorship rather than a performance test, and the founder now sells a rival machine, Slipstream.

Who else has it: Counter-current swimming is older than Endless Pools: Badu jets date to 1973 and the SwimEx paddlewheel to 1984. Master Spas' Michael Phelps line leans on a star endorsement the same way.

The catchUSA Swimming's 'official swim spa supplier' title is a partnership deal, not a product test. The USA Swimming title is an official-supplier partnership that involves no product testing. Endless' founding pool patent (US 5,044,021, filed 1989) has lapsed, and Endless' own founder now sells a competing swim machine.

What rivals and critics say3
  • The propeller unit sits inside the swim area, only the pricier E-Series swim spas have it, and you get fewer therapy jets and standard extras than in a Michael Phelps swim spa. Our check: True that SwimCross and RecSport models use jets and that the Hydrodrive sits at the front of the swim area; both brands' current-flow figures are self-reported.
  • A Fastlane stays visible above the water and complicates pool covers, and a prefab Endless pool limits size and shape and has no massage option. Our check: The deck-mount unit is visible, but Endless sells custom sizes and a four-jet hydrotherapy option ($1,610) for its modular pools, so the no-massage point is out of date.
  • Propeller systems need specialist technicians, parts can take longer, and you are committed to a specialty pool. Our check: The machine runs on a hydraulic power unit whose biodegradable fluid is changed in a five-year tune-up, and Endless says owners or local pros can service it without voiding the warranty; parts ship from its Pennsylvania factory.

How it’s built. In plain words.

What decides whether a tub lasts is mostly hidden under the shell. Here is what Endless Pools publishes about it, and where it publishes nothing, we say so.
