What this page is and is not
We have not used an Orca system. There is no lab here, no power meter and no owned unit - the method page sets out exactly what we do instead, which is read what sellers publish and check whether it holds together. For a brand we cannot sell, that is the whole of the job.
It also means one thing we can normally do, we cannot do here. Every Amazon product on this site gets its price re-checked automatically and its availability verified before we feature it. Orca is outside that pipeline. The prices below were read on 2026-09-26 and we have no way to keep them current, so treat them as a snapshot rather than a live figure.
What Orca publishes about its 1 HP chiller
The two cooling floors
Two degrees sounds like pedantry. At this end of the scale it is not. 32 F is the freezing point of water, so a chiller specified to 32 F is specified to the temperature at which the thing it is cooling stops being a liquid. 34 F is a cold but ordinary target. The difference between the two claims is the difference between a plausible specification and a boundary condition, and a buyer choosing on “how cold does it go” is being given both.
Neither figure comes with a cooling rate. That matters more than the floor itself. The best-documented chiller we track publishes “110 F to 36 F in about 5-6 hours” - a claim with a stated starting point, which is a claim you could falsify with a thermometer and an afternoon. A bare floor temperature is not falsifiable, because every chiller reaches its floor eventually in a small enough volume of water in a cold enough room. Under the taxonomy we use across the chiller hub, Orca publishes a figure without a rate, and it publishes two of them.
The figure that is missing: gallons
Orca’s chiller page does not publish a rated water volume. That is the single most useful omission on the page, and it is worth being precise about why.
Almost nothing in this category publishes BTU per hour, which is the figure that would actually let you match a chiller to a tub by arithmetic. Because that figure is missing nearly everywhere, our sizing guide has to fall back on the seller’s stated gallon rating - not because gallon ratings are rigorous, but because they are the only number on offer. Orca does not offer one. You can infer 110 gallons from the Mammoth bundle, but an inference drawn from a bundle tells you what the chiller is paired with, not what it is rated for. If you already own a 160-gallon tub, Orca’s own pages will not tell you whether this is the right unit, and horsepower will not tell you either.
Amps instead of watts, and what you can still work out
Orca publishes 7.9 A on cooling at 110 V. Multiply those and you get 869 VA. That is not the same thing as 869 W. A compressor is an inductive load, so its real power is its apparent power multiplied by a power factor - a number between 0 and 1 that Orca does not publish. 869 VA is therefore a ceiling on the draw, not the draw.
Ceilings are still useful, as long as you say that is what they are:
Here is the part that goes in Orca’s favor, and it would be dishonest to bury it. That 869 VA ceiling is below the 1,030 W that the best-documented Amazon 1 HP chiller publishes as its rated power. On the numbers each seller chose to print, the brand-direct unit may well be the cheaper one to run. We cannot confirm it, because one figure is a ceiling on apparent power and the other is a rated real power, and those are not directly comparable - which is itself the point. The full running-cost table shows what the rest of the category costs.
Where Orca is straightforwardly better than the category
Four things on Orca’s spec sheet are genuinely unusual, and three of them are things we have spent a lot of this site complaining that nobody publishes.
It puts a number on noise. 52 dBA. Across every chiller we track, exactly one Amazon listing has ever published a decibel figure, and as of today that unit is out of stock. A chiller lives in a garage, a bathroom or a balcony and cycles on and off through the night, so noise is one of the few specifications a buyer will notice every single day. Almost no seller will commit to a figure. Orca does. We cannot verify it, and neither Orca nor anyone else states the measurement distance, so it is not comparable across brands - but a number you can hold a brand to beats an adjective.
It names the compressor. “Panasonic Compressor” appears on the bundle page. No Amazon chiller in our data names its compressor at all. The inconsistency is odd - the same unit’s own page omits it - but a named component is a checkable claim.
It publishes a real ingress rating. IPX4 is a standard, unlike “weather-resistant”, which is a mood.
Its filled weight arithmetic actually works. The Mammoth is published at 110 gallons, 28 lb empty and 950 lb full. Water weighs 8.34 lb per gallon, so 110 gallons is 917 lb, and 917 plus 28 is 945 - within about five pounds of the published figure. That sounds like a low bar. It is not: we have caught sellers in this category whose stated filled weight and stated capacity cannot both be true. Orca did the sum and printed the answer.
The bundle, and what the premium actually is
The Mammoth bundle is $2,995 and pairs the 1 HP chiller with a 110-gallon two-person drop-stitch inflatable tub at 75 x 28 x 28 in, rated to 10 PSI, with a lockable cover, duffle bag, air pump and repair kit. Drop-stitch is the construction we rate highest in the inflatable roundup, so the tub is not the weak half of this package.
So the premium is real and it is large: roughly $960 on the chiller, about $1,845 on the complete setup. What it buys is disclosure and finish - a noise figure, a named compressor, an ingress rating, WiFi scheduling, a GFCI cord, ozone with a stated output - plus a direct relationship with one seller instead of a marketplace listing. What it does not buy is a longer warranty, a published wattage, a published gallon rating, or a cooling floor the brand states consistently.
What we will not tell you
We have not measured Orca’s 52 dBA, tested whether either cooling floor is reachable under load, or run a power meter on the compressor. We have not handled the tub, inflated it, or left it outside for a winter. We have no data on Orca’s warranty service, shipping damage rates or how long the ozone cell lasts. Orca publishes no return window or trial period that we could find on either page, and we are not going to assume one exists - if that matters to you, ask them in writing before you pay.
Who should buy Orca anyway
If the unit is going somewhere you will hear it - a bedroom wall, a small apartment, a garage under a nursery - then 52 dBA is the only noise figure in this category from a seller currently shipping, and paying for a number instead of an adjective is a defensible reason to spend more. If it is going outdoors year-round, IPX4 and a GFCI cord are the right kind of specific. And if you want one company to call when it breaks rather than a marketplace seller, that is worth something no spec sheet captures.
If you are sizing to a tub you already own, Orca cannot currently tell you whether its chiller fits it, and that is a bad place to start a $2,195 purchase. If running cost is your first question, the brand makes you do arithmetic and still leaves you with a ceiling. And if the premium is coming out of the budget for the tub itself, the trade is a poor one - the four units below are what roughly $400 to $1,230 buys, and the first of them publishes more than Orca does.
Every pick, in full
Each write-up below shows the score broken into its six components, the specs the listing actually publishes, and the running-cost arithmetic where a wattage exists to compute it from.
#1 - Most complete spec sheet
TURBRO FrostCore F85, 1 HP Cold Plunge Chiller

| Rated draw | 1030 W |
|---|---|
| Cost per hour at full draw | 18.9 cents |
| Upper bound, running continuously | $137.82 per month |
A chiller cycles. It draws its rated power while the compressor runs and almost nothing while it does not, and how often it runs depends on ambient temperature, insulation, lid use and setpoint. We do not measure duty cycle, so we publish the two figures that need no assumption and no figure in between. Computed at 18.34 cents per kWh (June 2026). The method.
This is what a complete chiller spec sheet looks like: 1,030 W rated power, 9,553 BTU/h maximum cooling capacity, AC 110 to 120 V at 60 Hz, a 36 to 86 F range, and a stated cooling time with the starting temperature named. Every one of those is checkable, and together they let you predict what the unit will do in your room rather than hope.
The BTU figure is the one nobody else publishes and the one that actually lets you size a chiller properly. Horsepower is a compressor rating, not a cooling rating, and the relationship between the two varies by design. BTU per hour is the heat actually removed, which is the number that matters when you are deciding whether it can hold 132 gallons at 40 F in a warm garage.
At 1,030 W it is nineteen cents an hour at full draw - lower than both 1,200 W half-horse units here despite being a full horsepower, which is either better efficiency or a difference in how the figures were derived. The three-stage filtration is named by micron rating rather than described, and the ozone generator is a real sanitation method rather than a marketing word.
Buy it if
Someone who wants to size a chiller by arithmetic instead of by horsepower.
Skip it if
You want the smallest footprint. At 21 by 24 inches this is the largest unit here.
#2 - The only kit sized for its own tub
AS ColdPlunge 1 HP Ice Bath Chiller and 216 Gallon Tub Bundle
A 216-gallon tub paired with a 1 HP chiller the listing rates for 220 to 230 gallons - the only bundle here whose published chiller rating actually covers the tub in the box.
| Small-space fit | 14 / 20 |

No running cost can be computed. The listing does not publish a rated wattage, so there is no honest way to tell you what a session costs. We will not estimate one. How we compute running costs
This is the one bundle on the page that passes its own sizing test. The listing publishes a chiller rated to hold 220 to 230 gallons and puts a 216-gallon tub in the box, which leaves a small margin rather than a deficit. Every other kit here pairs a chiller with a tub larger than any rating its own brand publishes, so this is a low bar that almost nobody clears.
Six of our eight cold-gear checklist items are published, including a warranty term and a product weight - both of which most kits omit. The filtration is an external pump circulating through a 5-inch replaceable cartridge, which is a recurring cost rather than a rinsable screen, and worth budgeting for over three years.
No wattage is published, so the running cost cannot be computed and both computed cost components score zero. For a 1 HP unit intended for continuous operation that is the figure a buyer most needs, and its absence is the main thing holding this product's score down.
Buy it if
Someone who wants a large tub and a chiller that is genuinely rated to hold it.
Skip it if
You need to know what it draws, or you do not want a cartridge to replace.
#3 - Bigger tubs, same design
Active Aqua Water Chiller with Boost, 0.5 HP
The 1/2 HP version of the titanium chiller, rated to 172 gallons - and published at the same 190 W as the quarter-horse unit, which cannot be right for both.

A chiller cycles. It draws its rated power while the compressor runs and almost nothing while it does not, and how often it runs depends on ambient temperature, insulation, lid use and setpoint. We do not measure duty cycle, so we publish the two figures that need no assumption and no figure in between. Computed at 18.34 cents per kWh (June 2026). The method.
The published wattage on this listing is 190 W, identical to the 0.25 HP model from the same brand. A half-horsepower compressor moving nearly twice the heat cannot draw the same power as a quarter-horsepower one. One of those two figures is wrong, and there is no way to tell which from the outside.
We report it as published and score it as published, because the alternative is substituting our own estimate for the manufacturer's number, and an estimate dressed as a spec is exactly what this site exists not to do. But you should treat the running-cost figure for this unit as unreliable in a way the others are not, and that is worth more to you than a confident number would be.
The rest is the same well-proven design as the quarter-horse: titanium evaporator, digital setpoint, a boost mode for pulling temperature down faster, and a published one-year manufacturer warranty, which is one of only two real warranty terms in this category.
Buy it if
Someone with a 90 to 172 gallon tub who wants the titanium design at the larger size.
Skip it if
You are budgeting on the published wattage. It is almost certainly a copy of the smaller unit's figure.
#4 - Best for a bathtub
AS ColdPlunge 1/3 HP Cold Plunge Chiller
600 W, a 42 F floor, a reusable metal filter instead of cartridges, and a submersible pump in the box so it works with a bathtub that has no ports.

A chiller cycles. It draws its rated power while the compressor runs and almost nothing while it does not, and how often it runs depends on ambient temperature, insulation, lid use and setpoint. We do not measure duty cycle, so we publish the two figures that need no assumption and no figure in between. Computed at 18.34 cents per kWh (June 2026). The method.
The submersible pump is what makes this the bathtub answer. A chiller normally needs a tub with inlet and outlet ports; a bathtub has neither. Dropping a pump into the water and running two hoses over the rim is inelegant and it works, and it is the cheapest route to a cold plunge for anyone who cannot give up floor space for a tub at all.
Six hundred watts is eleven cents an hour at full draw, comfortably mid-range here. The 79-gallon rating is a good match for a standard bathtub, which holds somewhere between 40 and 80 gallons at plunge depth.
The reusable metal mesh filter rather than disposable cartridges is a genuine running-cost detail that gets ignored because it is not electricity. Cartridge filters are a recurring purchase; a rinsable metal screen is not, and over a year that difference is larger than the difference in power draw between two chillers.
An availability note, because we said we would keep it current: this listing went to "Currently unavailable" on 2026-09-09 and we routed its buy link to a search rather than to a product nobody could add to a cart. Re-checked on 2026-09-12, it is back in stock with a buy-box offer, so the link points at the listing again.

Anyone plunging in an existing bathtub rather than buying a tub.

Your tub is over 79 gallons.
Questions people actually ask
How cold does the Orca chiller actually get?
Orca publishes two different answers for the same unit. Its standalone 1 HP chiller page says 'Cools to: 32 F'. Its Mammoth bundle page, listing a chiller with identical dimensions, weight, amperage, noise figure and warranty, says 'Cools to: 34 F'. We cannot tell you which is right, and neither page publishes a cooling rate, so there is no way to check either figure against a stated starting temperature.
How much does an Orca cold plunge cost to run?
Orca publishes amps rather than watts: 7.9 A cooling at 110 V. That works out to 869 VA, which is a ceiling on the real draw rather than the draw itself, because a compressor's true wattage is its apparent draw multiplied by a power factor Orca does not publish. At that ceiling and 18.34 cents per kWh it is at most 15.9 cents an hour, or about $29 a month at six hours a day. That ceiling is genuinely lower than the 1,030 W a comparable Amazon 1 HP chiller publishes.
Is the Orca cold plunge worth the price?
The Orca 1 HP chiller is $2,195 and the Mammoth tub-and-chiller bundle is $2,995, read from Orca's own pages on 2026-09-26. The closest Amazon 1 HP chiller we track is around $1,230, and a complete 1 HP tub-and-chiller kit is around $1,150, so you are paying roughly $960 more for the chiller alone. What that premium buys is a published noise figure, a named compressor, an IPX4 outdoor rating and WiFi scheduling - none of which the cheaper units publish. Whether that is worth about $960 is a judgment about your room, not about the spec sheet.
Is Orca sold on Amazon?
No. Orca sells direct from its own site, which is why we earn nothing from this page and cannot price-track the units or fall back to a search listing if one sells out. Every figure here was read from Orca's own product pages on 2026-09-26.
What is the biggest problem with Orca's specifications?
Its chiller page publishes no gallon rating. Because almost no chiller in this category publishes a BTU figure, matching the seller's stated gallon capacity is the only sizing method available to a normal buyer - and Orca's chiller page does not give you one. You can infer 110 gallons from the Mammoth bundle, but inference is not a specification, and it tells you nothing about whether the unit suits a tub you already own.
