Benefits

Submerge into your

best self.

From boosting recovery and reducing inflammation to enhancing mental clarity, our ice baths brings proven benefits to your mind and body whether you're an athlete, a wellness enthusiast, or just looking to elevate your daily routine.

Accelerate Injury Recovery

Ice baths act like a supercharged whole-body ice pack, reducing pain and swelling from acute injuries. Speed up recovery time and get back to doing what you love.

Combat Inflammation Naturally

Reduce pain, recover faster, and boost immunity by lowering inflammation. Less inflammation can also mean a happier gut, improved mental health, and better protection against diseases.

Elevate Your Mood & Wellbeing

Ice bathing stimulates dopamine release, creating a natural mood boost and sense of calm. Regular cold plunging builds resilience to stress, leaving you feeling happier and more balanced.

Relieve Fatigue and Pain

Our Cold Plunge System resets your central nervous system after intense exercise, reducing muscle fatigue and soreness. With better circulation, bursts of endorphins, and a calm mind, you’ll recover faster and feel ready for the next challenge.

Ease Migraine Discomfort

Cold plunges reduce migraine frequency and intensity by narrowing blood vessels (vasoconstriction). This natural method can help limit the release of neurotransmitters that trigger migraines, providing much-needed relief.

Boost Your Immune System

Cold exposure helps boost white blood cell production, enhancing your immune system's ability to fight infections. Take fewer sick days and recover faster with a stronger immune response.

Ignite Energy and Metabolism

Ice baths activate brown fat, improve blood flow, and release stress hormones, all of which help increase your metabolism. Feel energized and ready to take on the day.

Sharpen Focus & Mental Clarity

Cold plunges stimulate neurotransmitters that boost focus, improve circulation, and promote mental clarity. Enjoy sharper cognitive function and enhanced concentration.

Calm Anxiety & Reduce Stress

Ice baths trigger endorphin release, helping you feel more relaxed and less anxious. Cold exposure reconditions your parasympathetic nervous system to better handle chronic stress, giving you a sense of control and calm.

Enhance Sleep Quality

Ice baths help regulate your body temperature, reduce stress, and relax muscles—all key to better sleep. Enjoy a deep, restful night’s sleep and wake up feeling refreshed.

There is nothing - no medication, no other form of exercise - that can shock you out of your head and back into your body like cold water can.

PhD Cold Exposure Therapy

The mental barrier one has to get over in a moment, it’s called willpower. Cold exposure is a very potent tool because of the amplitude and timing of adrenaline that it creates.

— Dr. Andrew Huberman

Neuroscientist

It’s a ritual for me, a silent thing I do by myself, the commitment to it, it’s super uncomfortable but I still do it everyday, I win one little battle everyday.

How It Works

Put Your Stress

On Ice

Stress is one of the biggest causes of disease and fatalities worldwide. Here’s how the Cold Plunge System keeps you cool and calm both in and out of the bath.

Cold Water Response

Cold water shocks your body into Fight-or-Flight mode.

Stress Hormone Surge

Fight-or-Flight mode triggers the rapid release of stress hormones.

Physiological Response

The surge in stress hormones cause an increase in heart rate, blood pressure, and alertness.

PNS Rapid Reversal

These extreme changes force an equal response by Rest-and-Digest response bringing your heart rate and blood pressure back down.

Increased Resilience

Frequently repeating this stress cycle conditions resiliency to stress while helping avoid the negative outcomes of chronic stress conditions.

Frequently

Asked

Questions

There are several ways to plunge, such as sitting upright in a barrel or reclining against an angled wall. At Submerge, we prefer a position where you sit with your feet stretched, knees bent, and back slightly arched without touching anything. This minimizes distractions, so we designed a flexible tub with a flat back to prevent shoulder rounding and provide support for your neck. Your neck, seat, and heels are the only touchpoints—everything else is immersed in cold water.

Our tubs are constructed with drop stitch materials, allowing them to be inflated to higher pressures for superior rigidity compared to standard inflatables. The unique shape of our Cold Plunge Tub requires it to be handmade, ensuring long-lasting quality.

The internal dimensions are 46.5" long, 27" wide, and 24.5" high, comfortably fitting anyone up to 6'2".

The Cold Plunge Tub is highly insulated, ensuring the water temperature will only increase by 1-2°F per hour when not in operation, even in hot outdoor conditions.

Once inflated, connected, filled with water, and turned on, the system is controlled via a smartphone app. The app allows you to turn the system on/off, set the desired temperature, monitor its status, and schedule operation times. After setup, you can plunge each day without thinking, it’s ready for you when you are.

The Ice Bath Chiller works as both a chiller and a heater, ranging from 37°F to 108°F. While heating is often an extra-cost feature, Submerge includes both chilling and heating for the same price.

The Ice Bath Chiller cools water by 6-7°F per hour. Starting from room temperature (73-74°F), it can reach 40°F in about 5-6 hours. Heating is faster, taking 25-30% less time than cooling.

High horsepower is only necessary for commercial systems in constant use. Paying more for a machine that cools an hour faster isn’t worthwhile if you’re using it for just 5-10 minutes a day. Higher horsepower also means larger fans and louder operation, which is why most luxury or high end home ice baths don’t use high horsepower systems.

No, it’s not necessary to run the Ice Bath Chiller constantly. Once your desired temperature is reached, usually in 3-4 hours, you can turn it off. The Cold Plunge Tub is well-insulated, and the water temperature will only increase by 1-2°F per hour, even in hot outdoor conditions. Running the chiller twice a day for 4-6 hours each session is enough to maintain the ideal temperature and keep the water clean.

No, the water doesn't need to be extremely cold to be effective. A temperature of 57°F is a great starting point. There's no rush to make it colder—everyone progresses at their own pace. Some may never go below 50°F, while others may challenge themselves to lower temperatures.

Staying in an ice bath for 5-6 minutes is enough to get most of the benefits. The general rule is longer for less cold, shorter for colder temperatures for example, 5 minutes at 56-57°F or 2-3 minutes at 37°F. Start at a comfortable temperature for 5 minutes, then gradually lower the temperature and adjust the duration as you progress.

The best time is generally in the morning before starting your day. Avoid ice baths within 4 hours of exercise, as it can impact muscle gains. Evening baths can affect sleep unless you warm up adequately afterward. A morning ice bath is an invigorating way to kick off the day.

Daily ice baths are ideal. The more often you do it, the better you'll adapt, eventually tolerating colder temperatures and maximizing the benefits.

Taking a break, such as when traveling, provides an opportunity to observe your body without the routine. When you return, it will feel familiar but different, offering insight into your progress. Breaks are natural and can help you notice and appreciate the long-term benefits of regular ice bathing.

The Cold Plunge System comes with a 3 stage water filtration system; a metal strainer for the big stuff, a 20 micron filter for the small stuff, and o-zone disinfection for everything you can’t see.

No, additional sanitization is required, just like with any hot tub or pool. We recommend using a small amount of chlorine—about 5g per week—to keep the water clean. Some brands claim their tubs don't need chemicals or suggest expensive alternatives, but these are often less effective. The simplest solution is best: keep your water clean with minimal effort and cost.

To keep your Cold Plunge System running smoothly, regular maintenance is required. Weekly maintenance takes about 10 minutes, and monthly and every 6 months maintenance takes about an hour.

It depends on how frequently you use your ice bath and how clean you are when using it. As a general rule, it's best to drain and refill the water every 1-2 months or as needed.

No, we do not recommend using Epsom salts or other salt-based additives to your Cold Plunge System. They can potentially damage the Ice Bath Chiller and void your warranty. It also takes time for the skin to absorb minerals and since you spend so little time in your ice bath there aren't any health benefits to adding anything to the water.
