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!

Saved $500!!!

Called Plunge Crafters with a question about a product I purchased. Spoke to an actual person, Nathan, who was exceptionally helpful and even helped me save over $500 by purchasing a new chiller through them vs the competition

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.

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.

BEST CUSTOMER SERVICE EVER. No one comes close!

Nathan and Kristin at Plunge Crafters are quite simply the best customer service providers I have EVER experienced. Every issue and question I had from purchase to installation were handled superbly well! I am recommending Plunge Crafters to everyone I know. We use the plunge pool every day and it makes a monumental difference in our day. Thank you!!!!

FREQUENTLY ASKED QUESTIONS

How cold does a cold plunge chiller get?

The Plunge Crafters Cold Plunge Chiller Pro 1/2HP cools water down to 39°F (4°C), making it one of the coldest consumer-grade cold plunge chillers available at its price point. The 1/3HP version reaches 42°F. For context, most cold therapy protocols recommend water temperatures between 39°F and 59°F — the Pro Chiller's 1/2HP model covers the full therapeutic range. No ice required.

What is the difference between a 1/3 HP and 1/2 HP cold plunge chiller?

Choose the 1/2HP Chiller Pro if:

  • You live in a warm climate (Texas, Florida, Arizona, or anywhere ambient temps exceed 85°F regularly)
  • You want water at or below 40°F for deep cold therapy
  • Your tub holds more than 100 gallons
  • You plan to plunge daily or have two people using the system

Choose the 1/3HP Chiller Pro if:

  • You live in a cooler climate (average ambient temps below 80°F)
  • 42°F is cold enough for your recovery goals
  • Your tub holds 100 gallons or less
  • You're budget-conscious but still want to eliminate ice permanently

Rule of thumb: If you're unsure, go with the 1/2HP. The extra cooling power matters in summer and in any sun-exposed outdoor setup. The performance gap between 39°F and 42°F is significant for serious cold therapy practitioners.

Does a cold plunge chiller work in hot weather?

Yes. The 1/2 HP Pro Chiller is specifically built for warm climates and performs reliably in ambient temperatures above 85°F, making it the right choice for outdoor setups in Texas, Florida, Arizona, and similar climates. For best performance in extreme heat, place the chiller in a shaded area with at least 24 inches of clearance behind the unit and 12 inches on each side for proper ventilation. Restricting airflow around the unit is the most common cause of reduced performance in hot weather. The 1/3 HP model is not recommended for climates that regularly exceed 80°F.

What electrical requirements does a cold plunge chiller need?

The 1/2 HP Pro Chiller runs on standard 110V/120V household power and plugs into a regular 3-prong outlet. No special wiring or dedicated circuit is required for most home setups. The unit draws approximately 8 to 10 amps during operation. If you are installing in a garage or outdoor space, make sure your outlet is GFCI protected, which is standard for any outdoor or wet-area electrical outlet. If you are unsure, consult a licensed electrician before installation.

How long does it take a cold plunge chiller to cool water?

Thanks to its industry-leading high-flow rate, the Chiller Pro can cool water down to 39°F (2.7°C) in just a few hours, depending on ambient temperature and tub size. It's powerful enough to maintain consistently cold temperatures—even with regular use.

Will this chiller work with my existing cold plunge tub?

Yes. The Chiller Pro is designed to be universally compatible with most plunge tubs and tanks that support 3/4", 1/2" NPT or BSP threaded fittings. It works seamlessly with all Plunge Crafters tubs and can be easily integrated into third-party tubs with minimal setup.

Does this chiller work with a Rubbermaid stock tank?

Yes. The Plunge Crafters Cold Plunge Chiller Pro is fully compatible with Rubbermaid 100-gallon and 150-gallon stock tanks — the most popular DIY cold plunge tubs in the U.S. The chiller ships with 3/4" high-flow, steel-reinforced, pre-insulated hose assemblies that connect directly to standard 3/4" NPT threaded fittings used on our tank bulkhead adapters. Setup takes 10–15 minutes. No special plumbing knowledge required.

What should I look for in a cold plunge chiller?

The Chiller Pro is engineered with a high-flow water pump, 3/4" steel reinforced insulated hose assemblies that wont kink and titanium heat exchanger—ensuring faster cooldowns, cleaner water, and unmatched durability. Not to mention having WIFI connectivity that allows you to control your chiller from your phone.

How loud is a cold plunge chiller?

It’s designed to run quietly and efficiently. While any high-performance cooling system produces some sound, the Chiller Pro is optimized for low-noise operation so you can enjoy peaceful plunges without a disruptive hum.

Does a cold plunge chiller filter the water?

Yes. It includes a 20 micron filtration system that keeps your water crystal clear and hygienic. This ensures fewer water changes and a more pleasant, maintenance-free experience. Extend the time between your water changes even further when adding the InlineO3 Ozone Generator Bundle.

How hard is it to set up a cold plunge chiller?

Very. Setup takes just 10–15 minutes. Simply connect the hoses, plug it in, and let the Chiller Pro do the rest. No fancy plumbing or technical expertise required.

Can I use my HSA or FSA to pay for a cold plunge?

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.
