Active Aqua 1/3 HP All in One Outdoor Cold Plunge Chiller

Active Aqua 1/3 HP All in One Outdoor Cold Plunge Chiller

Regular price $1,049.95 USD
Sale price $1,049.95 USD Regular price $1,295.95 USD

Most water chillers were never meant to live outside, which leaves outdoor plungers choosing between hauling their chiller indoors or voiding a warranty. The Active Aqua 1/3 HP All in One solves it: a rainproof, outdoor rated system that cools water down to 39°F with the pump, 20 micron filtration, and ozone sanitation already built in. Connect the plumbing to your tub, plug the GFCI protected cord into a standard outlet, and plunge.

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

It pairs perfectly with backyard stock tank builds and our cold plunge tubs.

Note: No external pump is required; the circulation pump is built in. Drain and disconnect the unit during freezing weather.

FREQUENTLY ASKED QUESTIONS

Is the Active Aqua chiller good for cold plunges?

Yes! The Active Aqua 1/3 HP All in One is the outdoor workhorse of the lineup, built for cold plunge duty with the circulation pump, 20 micron filtration, and ozone sanitation already built in. Unlike the indoor Active Aqua units, there is nothing extra to buy: connect the plumbing to your tub, plug in the GFCI protected cord, and plunge. Plunge Crafters is an authorized Active Aqua dealer, so every unit ships new with the full manufacturer warranty.

How cold does the Active Aqua 1/3 HP chiller get?

It cools water down to 39°F, with a digital set point range of 39°F to 82°F. That covers the full cold therapy range, from deep cold at 39°F to milder recovery temperatures, with no ice required. Once your water reaches the set point, the chiller cycles on and off automatically to hold it. Your tub size, insulation, ambient temp and sun exposure still affect how fast it pulls down and how hard it works to hold temperature.

What size cold plunge tub does the 1/3 HP All in One chiller support?

With its built-in 800 GPH circulation pump, it is sized for typical backyard cold plunge builds, including standard stock tanks. Not sure it is the right match for your tub? Contact us with your tub's gallon capacity and we will confirm fit before you order. Building indoors instead? The Active Aqua 1/4 HP covers tubs from 40 to 92 gallons and the Active Aqua 1/2 HP covers 90 to 172 gallons.

Can I use the Active Aqua 1/3 HP chiller outdoors?

Yes, that is exactly what it is built for. It has a rainproof design, corrosion-resistant ABS housing, and a GFCI protected power cord, and it is approved for outdoor use. It is the model to choose for backyard, patio, and poolside cold plunge setups, and it works just as well in a garage or gym if you ever move it indoors. Shop all cold plunge chillers.



Does the Active Aqua chiller come with a water pump?

Yes, the pump is built in. An integrated 800 GPH circulation pump moves water between your tub and the chiller, so there is no separate pump to buy, size, or plumb. That is one of the biggest differences from the indoor Active Aqua units, which require an external pump sold separately.

What is the Boost function on the Active Aqua chiller?

Boost runs the chiller at maximum output to accelerate cooling, useful right after you fill the tub or do a water change. Once your water reaches the set point, the chiller cycles on and off automatically in normal mode to hold your temperature, so you only run Boost when you need the fast pull-down.

Does this Active Aqua chiller filter the water?

Yes. It has built-in 20 micron filtration with a washable, reusable cartridge, plus a built-in ozone generation system that helps keep water clean and clear between changes. Rinse the filter cartridge regularly and you will go longer between water changes with less chemical maintenance. The indoor Active Aqua units do not include filtration, which makes this the pick if you want sanitation handled in one box.

What are the electrical requirements?

It runs on standard 120V household power, drawing 5.0 amps during operation, and the GFCI protection is built into the power cord itself, which is exactly what you want for outdoor wet-area equipment. No special wiring or dedicated circuit is required for most homes. Never run it on an undersized extension cord.

What fittings are included with the Active Aqua chiller?

It ships with 1/2", 3/4", and 1" fittings plus two water adaptors, so it connects to the plumbing used in most DIY cold plunge builds. Need adapters, hose, or bulkheads to finish the connection to your tub? Browse our fittings, hose and bulkheads collection or contact us and we will spec the connections for your build.

How much space does the chiller need around it?

Install it on a stable, level surface positioned below your tub's water level, with clearance on all sides so it can pull in air and dissipate heat. The locking caster wheels make it easy to roll into position and keep it planted once it is there. Keep it out of direct sunlight where possible: shade helps any chiller work less to hold temperature.

Can I leave the outdoor chiller running in winter?

Not through freezing weather. Drain and disconnect the unit when temperatures drop below freezing to protect the pump, plumbing, and heat exchanger. Water expands as it freezes and can crack internal components. If you plunge year-round in a cold climate, move the system to a garage or covered space for the winter months.

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! 😍

Outstanding Chiller

⭐️⭐️⭐️⭐️⭐️

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!!!!
