Meet Monk, the world’s first smart ice bath


Cold plunge with the power of technology

You deserve to meet the version of you on the other side of the ice. Stronger. More resilient. In control. That’s why we’re making it easier, safer, and slicker to transform your life with the world's first smart ice bath and cold water therapy app.

Schedule your plunges remotely, integrate with your wearables and track your cold water progress with key health indicators.

Self-cleaning ozone sanitisation

Ozone is so potent that it kills viruses, bacteria, and algae. No chlorine, chemicals, or manual cleaning here, folks. Simply change the water every 3 months, by connecting the hose to the reversible flow valve.

Temperature controlled

At the touch of a button – on the ice bath or the app. No more guesswork or temperatures that don't match the health benefits you deserve.

Beautifully compact

Small enough to fit through doorways, yet spacious enough for 6'6 125kg athletes. Built for both indoor and outdoor use (and so beautiful it’s guaranteed to make your neighbours jealous).

Plug and plunge

No plumbing needed – just fill Monk with water and you’re ready to plunge.

Energy efficient

Our insulation's so powerful that our cooling unit only runs for minutes every hour (it's equivalent to running an LED lightbulb). Monk will keep the water cool (even in warmer climates), and stop it freezing over when the temperature drops. Magic.

your personalised cold water therapy coach

Get ready for personalised, immersive plunges that combine guided audio, soundscapes, and breathwork to instil you with the confidence and resilience you need to override your flight or fight system, and discover just how capable you are. We’re developing game changing protocols that are tailored to your goals, from muscle recovery to neuroprotection. This is 5,000 years of ancestral wisdom matched with cutting edge science - and it’s coming soon to your pocket.

Integrate with your health wearables

You can’t manage what you can’t measure. Monk integrates with your wearables, like Whoop, Oura, and many more, so that you can see how cold exposure impacts important health metrics over time, like HRV and sleep, all in the Monk dashboard.

Schedule your plunges

Your life, your schedule. You can schedule your plunges in advance, and Monk will be at the temperature you want, when you want it. Afternoon triathlon recovery on Wednesdays, and a colder morning wake-up on Thursday? Monk’s got you covered. Plus, you can add it to your calendar for added accountability.

about the app

“For me, ice baths are about mental resilience as much as they are physical recovery. This is a wellness innovation that helps me be a better athlete and human. I’ve witnessed the evolution of Monk firsthand, and I stand by them – not just as an investor, but as a true believer in their mission to become the world leaders in cold water therapy.“


"Cold water therapy has had the biggest impact on my mental clarity and my mindset. It's helped me to make better business decisions at BrewDog, and I've been using the Monk prototype before important meetings and most mornings. Unquestionably, Monk is leading the seismic shift in health."

Jo Dalton, Founder & Entrepreneur

"As a professional who needs to stay at the top of my game, I found the stress relieving, endorphin-creating, immune-boosting benefits immense. But the options of continually buying bags of ice in ugly tubs & barrels didn’t fit my high standards around aesthetic or the environment. I cannot recommend Monk enough."

Backed by athletes, leaders, and technologists


It’s nearly time to shed the weight of the digital world with Monk.⁠



Mental Health

Depression, anxiety, and stress have been closely linked to chronic inflammation. Not only is anti-inflammation one of CWT’s most profound physiological responses, it’s also proven to stimulate the vagus nerve. On a biochemical level, CWT created a euphoric explosion of neurotransmitters, and has been proven to increase dopamine by 250% and norepinephrine by 530%.

Mental Health benefits

Cold water immersion has been shown to provide long-lasting positive changes to our immune, lymphatic, and circulatory systems, which underpin our immunity and ability to deal with disease and infection.

Find out more on how CWT increases disease-fighting white blood cells, boosts natural killer cells that are related to tumour immunity, and increases glutathione, an antioxidant that’s vital for detoxing and combating oxidative stress in the body.

Fat loss + Metabolism

When you cold plunge, your body goes into overdrive to stay warm. To cope, it burns stored white fat (aka “the bad fat”) which aids weight loss, activates brown adipose tissue (aka “the good fat”), and has been proven to boost metabolism by 350%.

Cold exposure has been shown to improve leptin sensitivity (one of the most important regulators of body mass). Learn more about brown fat, hypothyroidism, leptin, and thermogenesis.

Muscle Recovery

There’s a reason elite athletes and sports teams have used ice baths as an integral part of their recovery protocols for decades. Predominantly, cold immersion causes blood vessels to tighten (vasoconstriction) which stems inflammation, helps the lymph nodes move lactic acid and other toxins out of the body, increases blood flow and speeds circulation, and delivers much needed oxygen and nutrients to the muscles which aid their recovery. 

Learn more about lactic acid, how norepinephrine lowers inflammation, what training styles benefit most, and exertional hyperthermia.


Cold therapy activates cold shock proteins, which have been found to play a role in neurodegenerative diseases like Alzheimer’s and Parkinson’s, and acute and age-related diseases including cancer, type 2 diabetes, chronic kidney disease, atherosclerosis, chronic liver disease, and asthma.
