Endless Pools & Swim Spas: Cost, Used Buying Guide, Is It Worth It
What an Endless Pool costs new versus used in 2026, how the swim current works, the seven checks to run before you buy, and what the pad, electrical and crane really add.
The short version of Endless Pool cost in 2026: a new one runs $41,000 to $42,000 for a current-model 7 by 14 foot unit, and a used one on our marketplace sells for anywhere between $8,848 and $35,848 depending on the model and how it was cared for. Across all 82 swim spas we have handled, the median price is $17,724. That is the number to hold in your head, because almost every conversation about swim spas starts with someone quoting a dealer figure that is roughly double it.
I move large backyard equipment for a living. Swim spas are the heaviest, most expensive, most logistically painful category we touch, and they are also the one where buying used saves the most money in absolute dollars. So here is what an Endless Pool actually costs new and used, how the swim current works, what to check before you pay, and what installation really involves once the truck leaves.
Endless Pool cost in 2026: new versus used
A used Endless Pool costs roughly half of new, and a used swim spa from any brand costs roughly half of new. Here is what has actually moved through Commonplace.
| What it is | Price | Notes |
|---|---|---|
| New 2025 Endless Pools EP407, 7 by 14 ft | $41,450 | Current model, cover and heater included |
| Used Endless Pools SwimSpa, like new | $35,848 | Top of the used range |
| Used Endless Pools E550, good condition | $29,146 | Fitness System, swim machine equipped |
| Used Endless Pools RecSport R500, like new | $25,248 | Recreation model rather than a lap trainer |
| Used Endless Pools 12 ft, like new, heater and cover | $17,449 | The realistic middle of the market |
| Used Endless Pools 17 ft, like new | $10,948 | Older generation, still swimmable |
| Used indoor Endless Pool, good condition | $8,848 | Floor of the market. Inspect hard |
| Median across all 82 swim spas we have listed | $17,724 | All brands, all sizes |
Two things jump out of that table. The first is that the drop from new to used is enormous in dollar terms. A $41,000 unit becoming a $17,000 unit is a $24,000 swing, which is more than most people spend on a car. The second is that the used range is wide, $8,848 to $35,848, and the spread is not mostly about age. It is about the swim system, the size, and whether the previous owner kept the cover on.
Swim spa prices do not follow model year the way cars do. A well-kept twelve year old shell with a good equipment pack is worth more than a five year old one that sat uncovered through two winters.
How the Endless Pools swim current actually works
Endless Pools generate their current with a propeller in a housing, not with jets. That single design choice is what you are paying the brand premium for, and it is a real difference rather than a marketing one.
A jetted swim spa pushes water at you through several nozzles. The result is fast, narrow and turbulent, and it tends to shove you around in the middle of a stroke. A propeller-driven swim machine moves a much larger volume of water more slowly across the full width of the swim lane, which feels closer to actual open water. If you are a swimmer with real technique, you will notice the difference in about thirty seconds. If you want a warm place to jog against resistance and play with your kids, you will not, and you should buy the cheaper jetted unit and keep the difference.
Endless Pools sells two families and people confuse them constantly. The Fitness Systems and SwimCross lines are self-contained above-ground swim spas, the ones on this list. The Original Endless Pool is a fixed installation, usually indoors or in-ground, built into a room or a deck. If you are shopping used, read the listing carefully, because an indoor Original is a very different purchase from a portable swim spa and it is not something you casually relocate.
Endless Pools versus Master Spas versus the rest
Here is how the brands sort out on our marketplace, with real used prices attached.
| Brand | Used range we have seen | Current type | Who it suits |
|---|---|---|---|
| Endless Pools | $8,848 to $35,848 | Propeller swim machine | Actual swimmers who care about stroke quality |
| Master Spas H2X and Michael Phelps | $9,749 to $33,171 | Jets | Family use, therapy, wide dealer network |
| PDC TruSwim | Around $23,948 | Jets, dual zone available | Households that want a swim side and a hot side |
| Marquis and American Whirlpool | $16,798 to $27,848 | Jets | Mid-market with good build quality |
| Catalina and Aqua Living | $11,749 to $26,846 | Jets | Budget buyers, more variability unit to unit |
| Premium Leisure and similar | Around $8,749 | Jets | Entry point. Inspect the equipment pack closely |
Master Spas is the volume answer and the H2X line is genuinely good. Endless Pools is the swimmer's answer. Everything else is a value play, and the value plays are fine, as long as you inspect them like a used car rather than a piece of furniture.
One more option people forget: a dual-zone unit. A separate hot tub section at one end, kept at 102 degrees, with the swim section cooler. It costs more up front and more to run, and for a lot of families it is the version that actually gets used every day rather than twice a summer. If you are still deciding between this and a straight hot tub, our used hot tub cost guide covers the cheaper end of the same decision.
What to check on a used swim spa before you pay
Get it running with water in it before money changes hands. Every expensive fault on a swim spa hides until the pumps are under load.
- Run the swim current at full power for ten minutes. Listen for bearing noise and watch for a current that fades. On an Endless Pool, the swim machine is the single most expensive part of the unit.
- Look at the shell in raking sunlight. You are hunting for stress cracks around the jets, the steps and the corners, and for blistering in the acrylic. Surface scratches are cosmetic. Cracks are structural and they end the conversation.
- Open the equipment bay and photograph everything. Two or three pumps, a heater, a control box, a filter housing. Look for white calcium crust, green corrosion at the unions, and any repair done with tape.
- Ask when the unit was last full and heated. A spa that has sat empty and dry for two years has hardened seals and gaskets, and you will chase leaks for a season. A spa that was drained properly for winter is fine. Those are different answers.
- Weigh the cover. A waterlogged cover is both a $900 replacement and a sign the spa has been losing heat for a long time.
- Check every jet face and handrail. Missing jet internals are cheap individually and add up fast across forty of them.
- Get the model number and the electrical spec in writing. You need this before you can price the install, and it decides whether your panel can even feed the thing.
If a seller will not fill and run it, price the unit as if the swim system is dead. Sometimes that math still works. Often it does not.
Installation: the pad, the electrical, and the crane
The purchase price is not the project cost, and this is where swim spa buyers get surprised.
The pad comes first. A filled swim spa is a very heavy object, in the range of tens of thousands of pounds once you add water and people, spread across a footprint the size of a small bedroom. It needs a reinforced concrete pad or an engineered deck rated for the load, poured level. A patio slab that was fine for a hot tub is usually not fine for a swim spa. Get a contractor to confirm before you buy, not after.
Electrical comes second. Most swim spas need a dedicated 240 volt circuit with a GFCI disconnect within sight of the unit, commonly in the 50 to 60 amp range, and dual-zone models sometimes need two circuits. Your specific model's manual gives the real number. If your panel is already full, add a subpanel to the budget.
Delivery comes third, and it is the part people underestimate most. A swim spa does not go through a standard gate. It does not go around a house on a dolly. Most deliveries mean a crane lift over the house or the fence line, a permit in some towns, and a crew that has done it before. This is not a rent-a-truck-and-call-a-friend job. Our drivers handle the pickup, the inspection and the delivery, and you see the actual unit on a video call before it leaves the seller's property, which matters a great deal when the item weighs more than your car. Here is how it works. If you want a sense of the smaller version of the same problem, read how to move a hot tub.
What a swim spa costs to run
Expect more than a hot tub and less than a heated in-ground pool. A swim spa holds several times the water of a hot tub and is generally kept warm year round, so heating is the dominant line item and everything else is noise.
Three things drive that number more than the brand on the cabinet. The cover, because a waterlogged or ill-fitting cover is a heater running all night. The cabinet and floor insulation, which is where the cheaper brands cut cost. And your climate, because an uncovered spa in a Minnesota February is a different machine from the same spa in Phoenix.
Chemicals and filters are real but modest. Budget for a fresh cover if the one you inherit is more than five years old, and treat that as part of the purchase price rather than a surprise.
Is a swim spa worth it?
A swim spa is worth it if you will use it three times a week and your alternative is a pool membership plus a drive. It is not worth it if you are buying it to become a swimmer.
That sounds harsh, so here is the practical version. The people I see happiest with these fall into three groups: swimmers who want lap training at home without a commute, people rehabbing joints who need warm water resistance work, and families who wanted a pool but did not have the yard or the budget for one. The people who regret it bought the largest unit available for a hobby they had not started yet.
Buy used and the calculation gets much friendlier. At $17,000 instead of $41,000 you have absorbed the depreciation that already happened to someone else, and swim spas hold value reasonably well after that first drop. Our marketplace has sold 58 of these, so this is a real market with real comparables rather than a guessing game. Browse what is currently listed under hot tubs and swim spas, and if you are cross-shopping brands, the used Master Spas guide is the closest comparison to an Endless Pool at a lower price.
Endless Pool and swim spa FAQ
How much does an Endless Pool cost?
New, about $41,000 for a current 7 by 14 foot model with cover and heater. Used, between $8,848 and $35,848 on our marketplace, with most good units landing near $17,000. Add the pad, the electrical and the crane on top of whichever number applies to you.
Are Endless Pools better than regular swim spas?
For swimming, yes. The propeller-driven swim machine produces a wider, smoother current than jets, which matters if you have a real stroke. For soaking, therapy and family use, a jetted swim spa from Master Spas or Marquis does the same job for less money.
Is it worth buying a used swim spa?
Usually, because the savings are enormous in absolute dollars and the shell is the part that lasts. The risk is concentrated in the equipment pack and the swim system, both of which you can test in ten minutes by running the unit full of water before you pay.
How long does a swim spa last?
The acrylic shell will outlast the equipment by a wide margin. Plan on the heater, the pumps and the control board as consumable parts over a couple of decades, and treat the cover as a five to seven year item. A well-maintained swim spa is a twenty year purchase.
What electrical does a swim spa need?
A dedicated 240 volt circuit with a GFCI disconnect within sight of the spa, commonly 50 to 60 amps, and sometimes two circuits on dual-zone models. Get the exact spec from the model manual and have an electrician confirm your panel can carry it before you commit to the purchase.
Can you move a swim spa yourself?
No, and please do not try. These weigh thousands of pounds empty, do not fit through gates, and normally need a crane lift. This is the one category where the delivery logistics genuinely decide whether the purchase is possible at all.
The bottom line
Buy a used Endless Pool or swim spa in the $15,000 to $20,000 range, from a seller who will fill it and run it in front of you, and budget another meaningful chunk for the pad, the electrician and the crane. That is the honest total. At those numbers a swim spa is one of the better used-equipment buys in a backyard, because the depreciation curve is steep, the shell lasts decades, and the alternative is $41,000.
If you already own one and it has become a very large planter, list it with us. We handle the pickup, the inspection, the buyer and the payment, and you never meet a stranger in your driveway. And if you are buying, do the ten minute running test. It is the difference between a $17,000 swim spa and a $17,000 acrylic box.
