A cold plunge should invite stillness. The Immersion Tub was born from that idea. It combines two natural elements (stainless steel and red cedar) to create a recovery experience that’s both powerful and peaceful.
Inside, the tub’s 304 stainless-steel basin reflects clean, precise engineering. It resists corrosion, retains cold, and provides a perfectly smooth surface for full-body immersion. Outside, the hand-finished red cedar shell adds warmth, texture, and a natural scent that grounds you before you even step in.
The heart of The Immersion Tub is its 2HP commercial-grade chiller, capable of bringing water down to 32°F in a few short hours. It can even form its own ice, holding temperature with accuracy and consistency. The system maintains an even chill throughout so every plunge feels uniform from top to bottom.
This is a true plug-and-play system. No plumbing, no installation, no complex maintenance. Just fill the cold tub, connect power, and let it run. Within hours, the water reaches your set temperature, ready when you are. Every model ships with free U.S. delivery, a fully insulated lid, and a digital guide to help you begin your recovery routine.
Every detail of The Immersion Tub reflects NW Immersion Co.’s belief in functional beauty. It’s quiet, intuitive, and enduring. It’s made for those who understand that recovery is something you return to, again and again, until stillness becomes second nature.
Technology should never get in the way of peace. Our cold plunge tub was designed to make recovery smarter using quiet innovation to preserve the stillness that makes every plunge meaningful. It’s precision wrapped in simplicity, built for daily use without the daily effort.Technology should never get in the way of peace.

At the heart of the cold tub is its WiFi-connected control system. Through the LCD touchscreen or mobile app, you can adjust temperature, or schedule sessions to fit your day. The controls are responsive and intuitive, so you can step into the water when you’re ready, without waiting or second-guessing settings.
Maintenance shouldn’t interrupt the ritual. Inside the system, a filtration process, including a 20-micron filter and ozone treatment, keeps the water consistently clear and fresh.
It removes bacteria, odors, and debris automatically, meaning less time cleaning and more time recovering. No harsh chemicals, no draining after every use. It’s pure, safe immersion.
The built-in 2HP commercial-grade chiller cools to a steady 32°F or warms up to 107°F in hours. That range gives you full control, whether you want a deep freeze for muscle recovery or a soothing warm dip to unwind. Once you’ve found your ideal temperature, the immersive tub maintains it effortlessly, holding steady for as long as you need.
While the technology inside is advanced, the experience feels grounded and human. Every component is chosen for reliability and quiet operation. There are no flashing lights or noisy motors, only the low hum of readiness and the clean, steady cold waiting for you. It’s engineering that serves the ritual, not the other way around.
The Immersion Tub was shaped by craftsmen who know what cedar smells like after rain and how metal feels when it first meets water. Every material tells a story; a story about resilience, balance, and the beauty of simplicity.
Cedar has a calm of its own. It carries the scent of the forest and a warmth that softens the edges of the cold. Its natural oils resist moisture, decay, and bacteria, which makes it as functional as it is grounding. Each panel of red cedar is treated with a natural, non-toxic finish. It enhances durability while keeping the air inside the cold tub pure and clean. It’s part of the experience, breathing life and warmth into every session
Inside, the 304 stainless steel basin gives the Immersion Tub its core strength. It’s non-reactive, corrosion-resistant, and engineered to last through decades of use. Stainless steel keeps the water clean, maintains temperature longer, and reflects light in a way that makes the water itself look alive. Where wood gives character, steel gives permanence. It’s a partnership of nature and endurance.
Nothing in the Immersion Tub is accidental. The seams are smooth to the touch, the cedar joints are aligned with precision, and every connection between wood and metal is sealed for longevity. The finish feels like something made by hand because it is. Every curve and joint speaks of patience, the kind that only comes from a team that builds for people, not production lines.
The real power of cold immersion is in the way you feel when you step out. The Immersion Tub was built for that moment: the deep breath, the calm that follows, and the quiet confidence that stays with you long after the water drains.
Shop All Cold / Hot TubsRecovery is less about intensity and more about consistency. Using The NW Immersion Tub for just a few minutes a day can help the body recover faster, reduce inflammation, and improve circulation. But more than that, it trains the mind to slow down, to meet discomfort with awareness instead of resistance. Over time, the ritual becomes something you crave rather than endure.
Those who use cold immersion regularly report sleeping better, thinking clearer, and bouncing back faster from physical exertion. The sudden drop in temperature shocks the system into alertness, while the gradual return to warmth encourages balance. For athletes, it means better muscle repair. For professionals, it means mental reset. For anyone, it means feeling alive again.
There’s a moment, just after you plunge, when everything goes silent. The rush of thought fades, the air feels sharper, and for a few seconds, you’re completely present. That’s the stillness we build for: the pause that resets everything.
The Immersion Tub isn’t about luxury for its own sake. It’s reclaiming balance, the kind that modern life rarely allows. It brings you back to the simplicity of breath, body, and cold water. A reminder that restoration doesn’t have to be complicated.
