Maintenance & Care

The Cedar Duo Plunge features an integrated drain for simple and convenient water changes.

For optimal water quality, we recommend a full water refresh every 4–8 weeks, depending on usage.

Maintenance Schedule

  • Residential Use: Rinse filters every 2–4 weeks and replace every 4–6 weeks for peak performance.

  • Commercial Use: Rinse filters weekly and replace every 1–2 weeks to maintain high-volume hygiene.

Setting up your Cedar Duo Plunge + Pro Chiller is simple and can typically be completed in about 10 minutes. No plumbing or special tools are required.

Step 1 – Position the Tub

Place the cedar tub on a flat, stable surface capable of supporting the filled weight of the tub. Ideal surfaces include concrete, pavers, reinforced decking, or other solid foundations.

Step 2 – Connect the Chiller

Attach the included hoses between the tub and the Pro Chiller using the supplied quick-connect fittings and valves. Ensure all connections are secure and properly sealed using the provided sealing tape and O-rings.

Step 3 – Fill the Tub

Fill the tub with clean water to the recommended level (approximately 110 gallons).

Step 4 – Plug in the System

Connect the Pro Chiller to a standard 110V household outlet.

Step 5 – Set Your Temperature

Turn on the chiller and set your desired temperature using the control panel or mobile app. The system will begin cooling or heating the water automatically.

Installation Tips

  • Keep the chiller unit in a well-ventilated area for optimal performance.

  • For outdoor installations, we recommend placing the chiller under a cover or sheltered area to protect it from direct weather exposure.

  • Ensure the hoses are free of kinks or restrictions for proper water circulation.

Once installed, your system will automatically maintain the set temperature, so your plunge is ready whenever you are.

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.

Frequently Asked Questions

We build some of the most reliable, high-performance cold therapy systems on the market.

Why? Because NW Immersion was founded on a commitment to durability, quality, and real-world performance.

To achieve that standard, we partnered with world-class engineers to design complete cold therapy systems optimized for power, reliability, and long-term functionality.

From the beginning, we’ve had a simple rule: we only sell products we would use ourselves. Our standards are high, and every system we offer goes through months of testing and refinement. We obsess over every detail—from performance to build quality—until it meets the level of reliability we expect.

Only then do we bring it to our customers.

NW Immersion systems are built to perform, built to last, and built for people who take their recovery seriously.

Yes, the system can be used outdoors. However, we recommend placing the chiller under a cover or protected area to prevent direct exposure to rain, snow, and harsh weather conditions.

For optimal performance and longevity, the unit should be kept out of full weather exposure whenever possible.

If outdoor temperatures drop below 33.8°F (1°C), the chiller should be drained and brought indoors to prevent freezing damage.

Taking these simple precautions will help ensure your chiller continues to operate reliably for years to come.

  • Residential Use: Rinse filters every 2–4 weeks and replace every 4–6 weeks for peak performance.

  • Commercial Use: Rinse filters weekly and replace every 1–2 weeks to maintain high-volume hygiene.

  • If you experience a water flow failure or notice that the water flow drops below 14 L/min, check the filter element. A dirty or clogged filter can restrict circulation and should be cleaned or replaced as needed.
Cooling time depends on the starting water temperature, tub size, and ambient conditions, but most systems can reach cold therapy temperatures within a few hours.
Your NW Immersion Elite Pro Chiller can cool water down to 37°F and heat it up to 107°F, allowing you to customize your recovery or contrast therapy experience.
The system includes a multi-stage filtration system, including built-in ozone generator and external water filter that helps keep water clean and circulating properly.
The Elite Chiller runs on a standard 110V outlet, making installation simple without requiring special wiring.

Yes, the Cedar Duo Plunge + Pro Chiller can be installed indoors, provided the space is properly prepared.

Because the tub holds over 100 gallons of water, it’s important to place it on a strong, level surface that can support the filled weight of the tub and users. Many customers install their plunge in home gyms, wellness rooms, garages, or dedicated spa spaces.

We also recommend ensuring the area has adequate ventilation and proper drainage in case of splashing or water changes.

With the right setup, the Cedar Duo can turn any indoor space into a private wellness retreat for cold and contrast therapy.

Stories from the Steam

Our greatest pride comes from the people who use our saunas every day.
“
NW Immersion has been a great help during my sauna build. I found them a little late in the build process, but right in time. I was able to get beautiful tongue and groove clear cedar. I gave Eric my dimensions and he got me setup with exactly what I needed. Then to finish things out, he setup me up with cedar for my benches and walked me through the tips a tricks of making the style bench that he puts in his custom builds. Speaking of custom builds, he walked me through a few of them happening in his shop and they are well thought out and immaculate. I would recommend NW Immersion if you are looking for someone else to build a custom setup for you, and if you don't use them for a build you are working on yourself you are missing out on great pricing, and a wealth of knowledge and experience.

My wife and I are DIYers and we were looking for help in design and materials for building our in home sauna. We found NW Immersion online and decided to visit their showroom for ideas and material sourcing. Once we met Michelle and Eric, we knew we had walked into the right business to help us. They not only provided knowledgeable answers to a lot of our questions about design and materials, but they were also very encouraging along the way. Once we got started, I let Eric know what materials I needed and he had everything ready and waiting for me. I was a little worried that I didn't pick out any of the cedar pieces like I would normally do at a hardware store. Once I was finished putting up all the cedar pieces and putting together the benches, I realized that every piece of wood I purchased was high quality clear cedar. On top of that, Eric had estimated the perfect amount I needed for not only the ceiling and walls, both also for the construction of the benches. I would highly recommend sourcing your materials from NW Immersion if you are planning a sauna project and want to be sure you are getting the best quality materials at a good price. We completed out sauna and are excited with how it turned out. My wife and I thank Michelle and Eric for the help with our technical questions and encouragement they provided along the way. I will encourage anyone looking to buy or build a sauna to stop by NW Immersion's showroom, you will not be disappointed.

From the moment we stepped into Eric’s showroom we knew we had found the answer to making our outdoor sauna dream a reality. He and his wife helped us from design, installation, and operation in such a personal and understanding way. The craftsmanship and attention to detail in its construction is outstanding. Their commitment to providing us with the sauna of our dream was always evident in every conversation during the process. Eric sent regular photos and updates throughout the build and the day of delivery and installation they were both eager to make sure we had all our questions answered. Taking a sauna has become an important part of our health routine and we feel great! We cannot recommend NW Immersion enough. Thanks! Rick and Pat Zimmer Camp Lolo Zigzag, Oregon

We recently ordered a sauna stove kit from NW Immersion Co. Michelle was so helpful from start to finish. She was friendly and knowledgeable, able to answer all of our questions, and kept us up to date on tracking. While visiting their showroom we were given a tour of their build shop. They had several sauna units in various stages of construction. My husband and I were very impressed by the build quality and attention to detail that has clearly gone in to each unit. It was obvious that they are very passionate about delivering quality units to their customers. We will definitely be visiting them again soon to stock up on sauna towels and other accessories.
