NW Immersion Matte Black Duo Plunge + Pro Chiller

Built for Two-Person Immersion

The spacious tub design comfortably supports shared plunge sessions, making it ideal for couples, training partners, wellness spaces, and anyone who wants more room than a single-person cold tub.

Cold + Hot Therapy in One System

The Pro Chiller cools water down to 37°F and heats up to 107°F, allowing you to use the system for cold plunge, warm soaking, and contrast therapy routines.

Premium Matte Black Design

The matte black composite exterior creates a sleek, modern look that feels refined in both indoor and covered outdoor wellness spaces.

316 Stainless Steel Interior

The marine-grade stainless steel basin offers durability, cleanability, and a more elevated feel than plastic or inflatable cold plunge tubs.

Advanced Filtration + Ozone Sanitation

Integrated filtration and ozone sanitation help support cleaner, clearer water with less day-to-day maintenance.

App-Enabled Temperature Control

Set your desired temperature, monitor performance, and manage your plunge from your phone using the mobile app.

Simple Setup, No Plumbing Required

Connect the included hoses, fill the tub, plug in the chiller, and set your temperature. No permanent plumbing is required.

Designed for Home Wellness Spaces

Use it in a home gym, garage wellness space, covered patio, backyard retreat, or near your sauna for a complete sauna-to-plunge ritual.

Cold, Warm & Contrast Therapy

One System, Multiple Rituals

The Matte Black Duo is designed for more than one type of use. With both cooling and heating capability, it supports a range of home wellness routines.

Cold Plunge

Set your preferred cold temperature for daily cold exposure, post-workout recovery rituals, sauna-to-plunge sessions, or morning resilience training.

Warm Soak

Heat the water up to 107°F for a relaxing warm soak or gentler recovery session.

Contrast Therapy

Pair your plunge with a sauna to move between hot and cold, creating a complete contrast therapy routine at home.

Wellness note: This product is designed for general wellness, cold exposure, warm soaking, and contrast therapy routines. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or condition.

Recommended Placement & Airflow

Protect Your Investment with Proper Placement

The Matte Black Duo Plunge + Pro Chiller is designed for indoor or covered outdoor wellness spaces. For best long-term performance and protection, we recommend placing the tub and chiller in a covered or partially protected area rather than leaving the system fully exposed to the elements.

Like any system with electrical, refrigeration, and water-care components, proper placement and airflow are important for safety, performance, and longevity.

For best results:

• 
  Place the system under a covered patio, pergola, sauna shelter, wellness structure, garage, gym, or other protected area whenever possible.
  
• 
  Keep the GFCI plug and electrical connection protected from direct rain, heavy spray, pooling water, and standing water.
  
• 
  Keep the chiller vents, fan areas, and access points clear of leaves, dust, debris, snow, towels, storage bins, and anything that could restrict airflow.
  
• 
  Do not block chiller vents or access points.
  
• 
  Maintain proper clearance around the chiller so it can breathe and be serviced when needed.
  
• 
  Place the tub on a flat, stable, load-bearing surface with good drainage.
  
• 
  When ambient temperatures are expected to fall below 40°F, we recommend keeping the tub temperature set to at least 45°F to help reduce the risk of freezing damage to chiller components.
  

Proper placement helps the chiller operate efficiently, reduces unnecessary strain on the system, and helps protect electrical and mechanical components over time.

Benefits of Cold Therapy

Cold immersion is more than a recovery tool — it’s a powerful way to improve mental clarity, physical performance, and overall wellness. Regular cold exposure activates natural biological responses that strengthen the body and mind.

Improves Mood & Mental Health

Cold therapy triggers a significant release of dopamine, boosting motivation, focus, and drive while helping regulate emotions and build stress resilience.

Reduces Inflammation

Cold immersion helps reduce inflammation throughout the body and supports immune function by stimulating the vagus nerve, which plays a key role in regulating the body's inflammatory response.

Better Recovery & Performance

Cold therapy reduces muscle soreness and pain after intense activity by constricting blood vessels, reducing swelling, and limiting muscle spasms, helping the body recover faster.

Increases Metabolism

Exposure to cold activates thermogenesis, forcing the body to generate heat. This process can increase metabolism by up to 350% as the body burns fat and glucose to maintain core temperature.

Cold therapy is one of the most powerful natural tools for improving resilience, recovery, and long-term health.
