Water Treatment: Ozone
Ozone sanitation is a is a great chemical-free option for keeping your water clean. A generator attaches to the back of your cold plunge tub, releasing ozone into the water daily using an air pump. The ozone generator turns on and off by a timer, making it a hands-off maintenance option. While ozone can be a great sanitation method, you need to ensure you are entering the plunge after rinsing off and wearing swimsuit material only. Ozone is a powerful oxidizing agent which when dissolved in water, produces a broad spectrum biocide that helps eliminate bacteria and viruses; ozone for water treatment has been used since 1904. See also our Ozone FAQs and check out the video for more information. Please note, if you keep your cold plunge outside in freezing temperatures, ozone tubing will need to be monitored for blockages, and ozone should not be used in temperatures below 20 degrees F.
Water Treatment: Sirona
Our Sirona Water Maintenance Kit is a chlorine free and bromine free product that you’ll add to your cold plunge water based on the results of weekly testing; testing info and pH strips are included.
The Sirona Water Maintenance Kit is a stronger cleaning agent than ozone; it is ideal if there are a number of people regularly using your cold plunge or if your are not as diligent about rinsing off before getting in the water. See more information about Sirona use and testing on our care and maintenance page.

WHAT THEY’RE SAYING
We purchased our Desert Plunge Wide Grizzly 450 Cold Plunge about a month ago, using it daily since arrival. Two of my sons have assembled their own cold plunges, one with a stock tank and the other using the Grizzly 450. I had experimented with both tubs and after seeing the simplicity of utilizing the Grizzly 450 I was sold on the platform. I did a lot of research, watched a lot of YouTube reviews and read as many reviews as I could find on Desert Plunge. Besides the excellent reviews, the back story on why Matt and his wife started the business sold us on Desert Plunge.
Shipping, delivery and setup were as easy as the ordering process. The tub was ordered with the optional Ozone Generator pre-installed making for a professional and neat looking setup. We took the additional step of insulating all of the lines prior to doing the final assembly to reduce condensation, which has worked wonderfully. We were able to completely setup, fill and have the chiller cooling our tub within 30-45 minutes from the time it was taken off of the shipping pallet.
While the cost of the Desert Plunge was a little more than DIY, it was worth every penny to not spend the time tracking down, ordering, fitting and assembling the various parts necessary to start using our cold plunge. We are extremely pleased with our purchase from Desert Plunge.
I was super excited to purchase my Desert Plunge, and pleasantly surprised at how quickly it went from order to arrival. Every component was packed inside the cooler and the cooler was repackaged in its original Grizzly packaging, which in my opinion was a great way to minimize waste and ensure the product was adequately protected for delivery.
Assembly was so very easy and straightforward. I am super pleased with how quick I went from unpacking to assembled and filling it with water.
I have mine set to 44 degrees, which the chiller easily maintains, I live about 45 miles east of SF where the weather can get into the low 100s, so far this year we have hit high 90s and the water is within the degree range I configured the chiller to be in, consistently.
Sure I could have DIY'd it, but given the polished final product and the frustrations of sourcing the parts myself, it was an easy choice to purchase this product.
As someone who has often plunged elsewhere, but never at home it's been a real pleasure having the Desert Plunge now just a stone's throw away in my backyard. While I was initially intimidated when it arrived, the instructional video and ease of touching base with Desert Plunge HQ has made the first month a breeze. Looking forward to many plunges to come!
The "Grizzly" cold plunge tub is nothing short of AWESOME! It arrived within 10 days of ordering it (it had to ship to North Carolina and I had to wait a few days to schedule delivery due to my work schedule), took me literally about 15 minutes to set it up, and - after adding some ice bags to it to get the temp down - was ready to use in an hour (at 40 degrees). I've only been using it for two days but it is truly a dream from ordering to setting up to using. I watched a great video (by David Maus Jr. - they have the link on the "accessories" page for the ozone add-on) to take me through the step-by-step setup but all the connections (e.g. hoses to fittings on the tub) were numbered so even without the video, I think I could have figured it out fairly quickly even without the video. As background, I started doing "cold plunges" last fall using my outdoor pool after learning about the benefits through a podcast by Dr. Anthony Balduzzi of the Fit Father Project where he interviewed the Desert Plunge founder Matt Kuiper. After benefitting IMMENSELY from the cold plunges (the "serotonin/dopamine" effects are for real as are the circulatory, metabolic, muscle recovery, mental toughness, etc. benefits) throughout the winter, I started to experience a noticeable decrease in the benefits as the water in my pool warmed up in the spring. My wife INSISTED I get this as even she noticed the difference. I am SO glad I listened to her (as usual). I splurged and got the ozone and sanitation kit and I'm happy with both as I want to keep this thing clean and humming for as long as I can. The whole thing seems sturdy, the pump and filter are SO quiet, and I'm hoping that it lasts a LONG time. It's actually smaller than I thought (but exactly per the dimensions on this site) but I fit in it comfortably (I'm 6 foot even, about 165-170 lbs) and it's easy to step into. It may seem like a lot of money but I truly believe it's worth it given the MANY benefits I receive from it. IMHO - It's better to pay a couple of thousand and live a healthy, quality life now (I'm in my late-50s) than suffer for a couple of decades and pay TENS of thousands to doctors and pharmacies to heal all the the mental and physical aches (which is ultimately just treating the symptoms - NOT the causes) later. THANK YOU MATT.
First I want to thank the Family at Desert Plunge!! You are amazing and I wish you great success!!! My plunge was delivered to the house and the shipper did not show up with a lift gate. This was an issue as the driver had to pull it off of the truck thus damaging the cooler and the feet were missing and the unit had cosmetic damage. I reached out and was given a response immediately. I received new feet and after setting up did not notice any other issues with the unit. The plunge itself is very easy to set up as everything is numbered and they include video directions as well. I have been using it twice daily and could not be happier!!! Thank You so much Tammie and Matt!!! I wish every company had the same service and support.
