Cold water immersion involves immersing yourself in water at temperatures of less than 15°C for a few minutes at a time. Studies and research indicate that cold water below 15°C may have positive effects on recovery including reduced inflammation and muscle soreness. Additionally, cold water immersion may help build resiliency, increase energy through a 250% surge in dopamine release, boost metabolism, enhance immunity and improve sleep.

Routine mental resilience training: any time during the day, we recommend first thing in the morning!

Pre-workout: Cold plunging can be a great pre workout tool as it can help stimulate the nervous system and increase your focus and energy levels before a workout.

Post-workout: Research suggests cold plunging 4 hours post-workout to inhibit any hypertrophy muscle gains from your workout.

11 minutes per week. This can be separated however you wish! If you cold plunge daily, immerse yourself in the cold plunge for ~1.5 minutes per session. If you only cold plunge for example, three times per week, cold plunge for ~3.5 minutes per session. Cold plunging for more than 11 minutes per week shows no increased benefits.

Anyone! Cold plunging provides numerous physical and mental health advantages for those aiming to optimize their performance and overall well-being. Many people incorporate cold plunging into their routine for resilience training, enabling them to handle everyday stress. While cold plunging is widely known to be used by athletes, cold plunging is amongst the most effective, controlled ways to boost noradrenaline and dopamine levels, which is why they leave you feeling fantastic and eager to do it again, athlete or not!

While The Krýo Plunge chiller can operate in ambient temperatures down to 2°C/36°F, we recommend once ambient temperatures are naturally bringing the temperature of the water in your Krýo Tub down to 10°C to disconnect your chiller and keep it stored indoors for the remainder of the cold months of the year. The plus side of doing so, simply means less wear and tear on your chiller!

The Kryo Tub is made out of inflatable stand up paddle board material. Once inflated to 8psi, the tub walls are rock hard!

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.

The Kryo Tub is 62” long, 33” wide and 28” tall. We have seen individuals as tall as 6’7 comfortably sit inside of our tub!

The maximum inflated pressure of the tub and inflatable lid is 10 PSI. Filling past 10 PSI will void the warranty and may lead to irreparable damage to the Krýo Tub. When using the dual-action pump included with the Krýo Tub, it takes roughly 2-3 minutes to inflate The Krýo Tub and roughly 20-30 seconds to inflate the Krýo Tub lid.

Standard water pressure with garden hose: 15 minutes 

Standard water pressure, garden hose, RV water filter: 20-25 minutes.

The Krýo Plunge chiller is capable of cooling the water in the tub down to 1.5°C, making The Krýo Plunge the coldest portable ice bath in the world!

The Krýo Plunge can operate in ambient temperatures as high as 45°C/113°F and as low as 2°C/35°F. It is not recommended that the chiller operates in conditions below 2°C/35°F as the unit would be at risk of freezing and may cause severe, permanent damage. Our warranty does not cover damage due to use in conditions outside of this operating range.

Yes! The Krýo Plunge can be placed outside. Our chiller is IPX4 certified meaning, it can handle dusty environments and light water sprays. Keep in mind, the unit’s efficiency will decrease if the tub and chiller is placed in direct sunlight and the longevity of all components will increase if they are placed under shelter.

Our chiller is a 1HP commercial grade chiller. Many competitors offer ½ to ¾ HP chillers which take a long time to chill the water. Our 1HP chiller cools water 4x faster than most other ice baths. The cool down time will depend on the starting water temperature and ambient air temperature. We have found that the Krýo Chiller cools water at a rate of about 5°C per hour. The cool down process can be quickly sped up by adding ice while filling the tub with water.

Yes, our chiller can be adjusted remotely via the Bluetooth app provided upon purchase. The Bluetooth app includes customization options including how often you want the chiller to expel ozone into the tub, change the temperature of the water, or program the chiller to be at a specific temperature during a specific time of the day so the Kryo Plunge is always ready when you are.

We decided to add this sanitization feature in our chiller due to ozone acting as an antimicrobial agent that effectively eliminates bacteria, viruses, and other pathogens present in the water. Infusing ozone into the cold water of the Krýo Tub, the risk of infections and waterborne illnesses is significantly reduced, ensuring a clean and hygienic cold plunge experience. Many competitor chillers will not offer this option and you will notice when using other branded chillers that do not have ozone sanitization, the water inside the tub will become murky and look dirty after just a few cold plunges.

The Krýo Plunge offers a 1HP commercial grade chiller. Majority of competitors offer a ½ to ¾ HP chiller. Our chillers not only work great for personal, at-home use as they cool the water down at very fast rates but they can also be used in commercial settings.

The amount of electricity the Krýo Plunge uses is dependent on the ambient temperature, the set point of the water temperature, if it is placed in direct sunlight/shade, and local electricity rates. The unit is capable of being programmed via the Bluetooth app to minimize the amount of time it is at the coldest desired temperature which saves significant energy consumption. In general, we expect costs to be less than $1 per day.

When the water is in the desired range, the Krýo Chiller does not need to run and the unit is nearly silent. When cooling the water, the fan on The Krýo Plunge creates about the same amount of noise as a window AC unit, or roughly 60 decibels at 5 feet.

We offer a 1 year warranty on The Krýo Plunge and its peripherals against manufacturing defects and other issues associated with normal product use. Our warranty for commercial use is 1 year, only when purchased through The Krýo Plunge Commercial Package. This warranty does not cover wear-and-tear or abuse of the product. 

If you are interested in purchasing multiple units (3 or more), please send us a message to support@thekryo.com, and we will get back to you in regards to your specific needs.

If the standard, 1 year warranty period has expired, and something goes wrong, please send us an email (support@thekryo.com) and we will work with you on repairing any damaged components to get you up and running as soon as possible.

We offer a 30 day return window that the Krýo Plunge may be returned for a full refund (net return shipping costs) for any reason. The product must be received in like-new condition without damage for a refund credit to be issued. 

The Krýo Plunge is equipped with a 1HP commercial grade chiller and ozone sanitization. If used in a commercial setting, you must be on top of the Krýo Plunge maintenance protocol. This includes regularly cleaning the filter, strainer filter and change of water more regularly than if The Krýo Plunge were to be used for personal use. If your Krýo Plunge is being used in a commercial setting, and you have questions about how often you should be maintaining The Krýo Plunge, reach out to us at support@thekryo.com and our team will be happy to offer clear and concise support. 

We currently only ship to North America. If you are interested in shipping outside of North America, please contact our team at support@thekryo.com.

Our Chiller cools the water down upwards of 4x faster than most competitors. Our 1HP commercial grade chiller is equipped with state of the art technology, making our product the coldest portable ice bath in the world, capable of chilling water temperature down to 1.5°C. Many competitors do not offer ozone sanitization in their chiller’s due to most competitors offering dual temperature. Ozone sanitization cannot live in warm temperatures, which is why competitors do not include it. The reality of dual temperature chillers is it can take hours upon hours, loads of wear-and-tear and lots of electricity to bring the water temperatures from cold to hot tub temperature and back down to cold temperature. We do realize there are many DIY solutions for as cost effective as $200. This could include used chest freezers, steel troughs, etc. Keep in mind when proceeding with this route, your water will not stay clean and sanitary for long periods of time and will require a water change every few days. Not to mention, to cool the water below standard cold tap water temperatures of ~12°C, it will require you to purchase bags of ice which can cost upwards of $4 per bag. To drop water temperatures to ~7°C., it can take upwards of 8 bags of ice, costing $32 just to chill your tub. Once the ice melts and the DIY tub sits outdoors in an unshaded area, water temperatures will immediately start to drop, meaning you will have to continuously purchase ice.

Our lead time is posted on The Krýo Plunge product page underneath the cost of the product.

The Krýo Plunge is shipped in two boxes via UPS, FedEx, Canada Post or Purolator Ground right to your door. One box contains the Tub and the second box contains the Chiller. Please note that you must have someone present to sign for the Chiller upon delivery. 

It is very important that the Chiller always remains in its normal upright position (handles up). If the Chiller has been on its side or in any other position, it should be left upright for 12 hours before use. We recommend ensuring that all components are dry and drained before putting away for transportation. If shipping The Krýo Plunge, care should be taken to ensure that proper packing is surrounding the chiller to absorb shocks or impacts.

You can fly with The Krýo Plunge tub, no problem. However, flying with the Chiller is possible but it is considered an overweight item and can be difficult to protect appropriately. With the proper protective packaging, the chiller exceeds the maximum weight of checked luggage. We recommend the safer, cheaper option of shipping via FedEx, UPS or Purolator if you desire to air travel with it. We also recommend keeping the wooden crate that the Chiller is originally shipped in, even if you don’t plan to fly with the Chiller.

Our Chiller has built in 2-step water filtration and non-chlorine/bromine sanitization. The Krýo Plunge has an external strainer to catch any hair or debris from entering the unit, a built in ozone sanitizer and 20 micron filter for extra filtration. The high-flow water pump circulates 100% of the water every 15-25 minutes and ozone sanitization engages every 5 minutes.

Our once per week maintenance protocol takes less than 5 minutes. This allows you to keep the Kryo Plunge running optimally and the water clean and clear. We recommend setting a reminder in your calendar for a day of the week that works well for you to perform the weekly maintenance. You can follow along with our step-by-step maintenance protocol video here.

For most users plunging 1-2x/day in a residential setting who keep up with their sanitation, the water can last for months before draining and refilling. We recommend draining, cleaning the tub and refilling it roughly every 3 months, or as needed. 

The Setup and takedown process is very simple and no tools are required. All you have to do is inflate the tub with air with the dual-action pump provided, connect the hoses to the Chiller and plug the power cord in to a standard 120 volt outlet and fill with water. Simply reverse these steps for the takedown. On average, this takes 15-20 minutes for setup or takedown depending on your water pressure for filling the tub. We have a detailed video for both setup and takedown of The Kryo Plunge found here.

You can drain your Krýo Plunge a few different ways, depending on your setup. If set up outdoors, you can simply open the valves on the tub and let the water drain out. If you want to direct the flow of water somewhere nearby, you can use the Chiller hose to direct the water to drain. Click here for detailed instructions to drain your Krýo Plunge no matter what environment your Krýo Plunge is set up in.

If you are indoors or want to empty and drain somewhere further away (shower, bath tub, sink, etc.), we recommend using a submersible pump and dropping it inside of the tub so you can drain to your desired location. Click here for detailed instructions to drain your Krýo Plunge no matter what environment your Krýo Plunge is set up in.

The Krýo Tub is made of military grade drop-stitch material which is designed to have very minimal air leakage. The Krýo Tub may need to be topped up with air once every few months depending on local conditions, and can be done with the dual-action hand pump provided even if water is in the tub. To check on the air pressure of your Krýo Tub, simply connect your dual-action pump to the tub and the gauge will read the precise amount of PSI inside of the Krýo Tub.

Absolutely! The Krýo Tub can be used without the Chiller and you can add ice accordingly.

Epsom salts and other additives are not recommended as they are corrosive and would damage the heat exchanger in the Chiller.

Absolutely! Many customers of ours love setting up their Krýo Plunge on their balcony. It is very important to check with your building or your blueprints to verify the load rating. The Krýo Plunge weighs approximately 1100 lbs with the Chiller (~100lbs). To fill up, you can either use a faucet to garden hose adapter to attach a garden hose to your sink faucet and fill up via your sink or, you can purchase a submersible pump and attach a garden hose to the pump and drop it into your bathtub to fill up that way. To drain, we highly recommend utilizing a submersible pump to drain through your tub or sink indoors.

Absolutely! Many of our Krýo Plunge customers keep it in deployed in one spot and don’t utilize the portability. When inflated, the tub is very durable and sturdy and doesn’t look portable/inflatable! The benefit of portability can come into play if you ever decide you want to move it to a different location in your home, if you move homes, or decide one day you’d like to take it with you on a trip.
