Active Aqua 1 HP Water Chiller for Cold Plunge Ice Baths

Active Aqua 1 HP Water Chiller for Cold Plunge Ice Baths

Regular price $1,199.95 USD
Sale price $1,199.95 USD Regular price $1,499.95 USD

Running cold plunge in a hot climate or big tub, a two-person plunge, or a setup that gets used all day? The Active Aqua 1 HP is the largest chiller in the lineup, rated for reservoirs from 80 to 250 gallons with 10,050 BTU per hour of cooling. You get the same pure titanium evaporator, digital temperature control with a 39°F set point, and Boost mode as the smaller units, with the muscle to pull large tubs down to temperature fast and hold it there under heavy daily use.

Replacing the chiller on a Plunge Gen 1? This is the direct replacement. The factory connections on your Gen 1 thread straight onto the ports of the Active Aqua 1 HP, your factory pump and filter stay in place, and there are no adapters, reducers or new hoses to buy. Unthread the old unit, thread on the new one, plug it in, and you are back to cold water the same day.

As an authorized Active Aqua dealer, every unit ships from our Dallas, TX warehouse and is backed by the Plunge Crafters Guarantee.

Note: This unit is approved for indoor and covered outdoor use only (garage, basement, gym, or covered patio). For DIY builds it requires an external water pump with a pre-filter, sold separately; see our Danner water pumps. Plunge Gen 1 owners already have both built into the tub.

FREQUENTLY ASKED QUESTIONS

Is the Active Aqua chiller good for cold plunges?

Yes! The Active Aqua line has been a staple of the DIY cold plunge community for years, and the 1 HP is the largest unit in the lineup. It is built for oversized tubs, two-person plunges, and high-use setups where the chiller runs hard every day. Plunge Crafters is an authorized Active Aqua dealer, so every unit ships new with the full manufacturer warranty.

How cold does the Active Aqua 1 HP chiller get?

The digital set point adjusts from 39°F to 90°F, so you can dial in anything from deep cold therapy at 39°F to a milder recovery temperature. Once your water reaches the set point, the chiller cycles on and off automatically to hold it within a couple of degrees. With 10,050 BTU per hour of cooling capacity, the 1 HP pulls large tubs down to temperature faster than the smaller units and holds its set point even under heavy daily use. Your tub size, insulation, ambient temp and humidity still affect how cold you can get and how fast you get there.

What size cold plunge tub does the 1 HP Active Aqua chiller support?

It is rated for tubs ranging from 80 to 250 gallons, which makes it the choice for hot climates, two-person plunges, and gym or studio setups with heavy daily use. Running a tub in the 90 to 172 gallon range? The Active Aqua 1/2 HP is a better value. For compact tubs from 40 to 92 gallons, go with the Active Aqua 1/4 HP.

Can I use the Active Aqua 1 HP chiller outdoors?

Not in the open elements. This model is approved for indoor and covered outdoor use, which makes it ideal for garage, basement, gym, studio, or covered patio cold plunge setups. If your plunge lives outside, choose an outdoor rated chiller instead: the Active Aqua 1/3 HP All in One has a rainproof housing and a GFCI protected power cord and is built for the elements. Shop all cold plunge chillers.



Does the Active Aqua chiller come with a water pump?

Not in the box. For DIY builds this chiller needs an external high flow water pump with a pre-filter, sold separately. We recommend the Danner 1200, which is built for continuous duty. Replacing the chiller on a Plunge Gen 1? You do not need a pump. The factory pump and filter in your tub stay in place and do the job. Contact us and we will help match the pump and plumbing to your build.

What is the Boost function on the Active Aqua chiller?

Boost runs the chiller at maximum output to accelerate cooling, and it has two modes. Press Boost once for a 2-hour accelerated cycle, useful right after you fill the tub or do a water change. Press it twice for continuous 24/7 maximum chilling, which runs until you switch it off. Once your water is at temperature, you can leave the chiller in normal mode and it cycles automatically to hold the set point.

Will the Active Aqua 1 HP replace the chiller on my Plunge Gen 1 cold plunge?

Yes, and it is a direct swap. The connections already on your Plunge Gen 1 screw straight onto the threaded ports of the Active Aqua 1 HP, so you do not need adapters, reducers or new hose. Your factory pump and filter stay in place and keep circulating water exactly as before. The new chiller simply replaces your failed Plunge Gen 1 chiller. To swap it, unplug the old unit and unthread the two connections. Pull the seals from your old chiller and put them on your new chiller, then thread the connectors onto the new chiller. Plug into a GFCI outlet and set your temperature. If your Gen 1 pump has been weak, noisy or has failed, this is a good time to swap it too with our Plunge Gen 1 Water Pump Replacement Kit.

What are the electrical requirements?

The Active Aqua 1 HP runs on standard 120V household power with a regular 3-prong plug, drawing 1100W and 10.2 amps during operation. As with any equipment used near water, plug into a GFCI protected outlet, and never run it on an undersized extension cord.

What fittings are included with the Active Aqua chiller?

The 1 HP ships with 1 inch and 1 1/4 inch barbed fittings to support its higher flow rate. Those are larger than the 3/4 inch plumbing used in most DIY cold plunge builds, so plan on reducer fittings if you are connecting to an existing 3/4 inch loop. Replacing the chiller on a Plunge Gen 1? Skip the fittings: your existing connections thread directly onto the chiller ports. For DIY builds, browse our fittings, hose and bulkheads collection for adapters, or contact us and we will spec the connections for your build.

How much space does the ice bath chiller need around it?

Install it upright on a stable, level surface with at least 12 inches of clearance on all sides, including the back and top, so it can pull in air and dissipate heat. At 21 inches long by 15 inches wide by 20 inches tall and 75 lbs, this is the largest unit in the lineup, so plan your footprint before delivery. Keep it out of direct sunlight and away from high humidity and high heat sources. Never cover the unit or run it on its side. If it does get tipped, stand it upright and wait 20 minutes before powering it on to let the refrigerant settle.

Will the chiller remember my settings after a power outage?

Yes. The Active Aqua has a memory backup feature, so after an unexpected power loss it returns to your previous temperature setting automatically instead of resetting to the default.

Can I use my HSA or FSA to pay for an Active Aqua water chiller?

Yes. Plunge Crafters partners with Truemed to make cold plunge purchases eligible for HSA and FSA funds. This allows you to pay with pre-tax dollars, which effectively reduces your out-of-pocket cost by 20 to 35% depending on your tax bracket. To use your HSA or FSA card, select the Truemed payment option at checkout. You will complete a short eligibility process through Truemed and then apply your HSA or FSA funds directly to your order. If you have questions about eligibility, visit our HSA/FSA program page for full details.

How does the 30-day return process work?

If you are not satisfied within 30 days of delivery, contact our support team at info@plungecrafters.com to initiate a return. Return the product unused in its original packaging and we will issue a full refund once the item is received and inspected. Refunds are processed within 5 to 7 business days of receiving the return. Our support team is available seven days a week from 7 AM to 8 PM CST to walk you through the process if needed.

Great tub- came promptly

Great tub- came promptly, was easy to set up, and works great! Super cold-like, painfully cold if that’s what you’re into (that’s what I’m into, literally)! Company is eager to help, support, answer questions.
It is important to let it sit 24hrs after setup, to allow air to work its way out of the system.
Highly recommend

Top Quality

To begin, I was impressed with the customer service from day one, specifically when I spoke with a representative on the phone who promptly addressed and corrected the issue with the small pump being installed backwards. The hoses are of superior quality, unlike the inferior materials found in cheaper models, making this a worthwhile investment for those seeking durability and reliability.

Total game changer!

Total game changer! I absolutely love this tub from Plunge Crafters! From the sleek design to the quality craftsmanship, everything about this tub feels premium. It's super easy to set up, retains cold temps like a champ, and has totally become my go-to recovery ritual.

After just a few weeks of using it consistently, I've noticed real improvements in my energy levels, mood, and muscle recovery.

Highly recommend to anyone looking to add a serious wellness boost to their routine. Plunge Crafters knocked it out of the park with this one!

Portable, Easy to Set Up, and Perfect for Cold Plunging!

⭐️⭐️⭐️⭐️⭐️
This inflatable cold plunge tub is incredible! Not only is it durable and effective, but it’s also portable, which means I can take it anywhere—whether I’m at home or traveling, It comes with a bag to transport!

Setup was a breeze. It took me just a few minutes to inflate and fill, and I was ready to enjoy a refreshing cold plunge. The materials are high-quality and hold up great even with frequent use.

If you’re looking for a convenient and versatile cold plunge solution, this is it. Highly recommend it for anyone wanting to make cold therapy a part of their lifestyle, no matter where they are!

Once you order it also gets to you super quick! The order went out the next day and I received the product in a few days! 😍

⭐️⭐️⭐️⭐️⭐️

I’m beyond impressed with this cold plunge chiller! Not only does it deliver ice-cold water for the perfect plunge, but the quality and performance are top-notch. It chills the water quickly and maintains the perfect temperature with ease, making every session refreshing and rejuvenating.

What really stood out was how fast it shipped—I received it in just a few days! The setup instructions were clear, and the unit was up and running in no time. Best purchase!

Excellent Service and Solid Product

Ordered my chiller from Plunge Crafters on a Thursday and had it at my door by Saturday—can’t beat that kind of shipping speed. I set everything up on Sunday and thought I was having technical issues. I called the number that afternoon and was surprised when Nathan, the owner, answered the phone himself.

I explained what was going on, sent over a few photos and videos, and we exchanged several emails—on a Sunday. He wasn’t totally sure what the issue was, so he planned to reach out to the manufacturer and get back to me the next day.

As luck would have it, I found out they were located only about 30 minutes from me here in Texas (love supporting local when I can). I asked if I could bring the unit by and swap it out. Without hesitation, Nathan said yes.

Here’s where it gets good: I show up at their warehouse ready to exchange the unit, and Nathan already has a new one set up and running. He walks me through the setup, and pretty quickly I realize—turns out the issue wasn’t the unit… it was operator error. Once I mimicked the proper setup with my own unit, it worked perfectly.

I spent a few minutes chatting with Nathan and his wife—great people—then took my unit home. Got everything reconnected, fired it up, and boom, ice-cold water ready to go. Took my first plunge the next morning and couldn’t be happier.

The chiller looks great, works exactly as it should, and has no leaks or problems whatsoever. But what really stood out was the customer service—from the handwritten thank-you note on the receipt to the personal support on a weekend, to the flexibility and professionalism during the exchange process. I’ve been complaining for a while about how rare good service is these days, and this was hands-down the best I’ve experienced in a long time.

If you’re looking for a cold plunge chiller, I can confidently say you won’t go wrong with Plunge Crafters. Great product. Even better people.

This is the chiller setup I was hoping to find. Plunge Crafters nailed it!

I looked at a ton of chillers before finding these guys. Most were overpriced, confusing, or looked like a DIY nightmare.

Then I found Plunge Crafters. Straight up, this setup is awesome.

The ½ HP chiller handles Texas heat with no problem.
The filter is separate from the unit, so it’s easy to access and clean.
The hoses come wrapped in insulation.
It comes with a strong pump.
The clamps are plug and go. I set it up in minutes.

It’s simple, it works, and it doesn’t cost a fortune.

I already had a tub, but if I had to do it again, I’d buy everything from them.

I even visited their warehouse. It’s a great setup, and you can tell they care.

If you’re on the fence, stop overthinking it. These guys are legit.

Active 1hp chiller & water pump install kit

I purchased the Active 1hp chiller, Plunge Gen 1 water pump kit and Ozone Generator. Nathan and his crew were outstanding! Product showed up with 2 days. I had some questions on the water pump install and again Nathan helped me out and called back right away. Super easy to do business with them. I saved a ton of money and extended the life of my cold plunge for at least 5 years! Definitely recommend these guys. Great value!

very impressive machinery

very impressive machinery, well worth the $$$. 3rd times the charm, I tried 2 other chillers before this one and they were total garbage from the start never worked. the Chiller pro is performing like a champ it cools at an average of 5 degrees per hour. I purchased this machine for the health benefits, and I'm deeply impressed with this company's products. I only wish I could have purchased the tub along with the chiller, but price was out of my range so had to go with something cheaper less insulated and sturdy. I would give them a sixth star if I could.

First chiller for me

I got the 1/3 hp and it seems to be doing well enough for my 100 gallon Rubbermaid tank. Setup thru the app was easy enough and I can control the chiller on/off/set temps/ thru my phone. It’s only been a few days in use. I will say this company, Plunge Crafters has been excellent to deal with. I just came across them while searching for plumbing kits and I liked the company’s customer service so much that I bought my chiller thru them as well. Thanks Nathan and Kristin!

Highly recommended

I'm really happy with this purchase. This kit makes for such an easy setup because all the tubing, connectors, insulation, spares, and fittings to fit various tubs is included. No planning or trips to the hardware store necessary. The hoses come pre-assembled and labeled, the instructions are clear, and I was up and running quickly. Ease of use is great. Just flip the power switch, or plug it in to a simple timer, and everything turns on.

Got the whole shabang

Aries tub, 1/2 HP chiller, pump and Ozone cleaning system. Couldn’t be happier with this system, upgraded from my DIY version. Probably spent less money overall compared with what I had been patching together over the past couple of years. Much more aesthetic, efficient, effective, and quiet. Should have done it sooner. Customer service is top-notch every time I have made a purchase.

We use the plunge pool every day and it makes a monumental difference in our day. Thank you!!!!
