Resources & Guides

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.

Upgrades & Add-Ons

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.

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.

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.

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.

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.

The Elite Chiller runs on a standard 110V outlet, making installation simple without requiring special wiring.

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.

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.

Most cold plunges sold on Amazon and third-party marketplaces are import-drop-ship products: white-label acrylic or plastic tubs paired with an entry-level chiller and shipped from an anonymous warehouse. The NW Immersion Cedar Duo is a curated system, not a marketplace listing.

The tub uses Canadian Western Red Cedar over a 316 stainless steel interior — the same grade of stainless used in commercial food and medical equipment. It is paired with the 1HP Elite Pro Chiller our concierge clients specify for daily protocol use, not a stock economy unit.

You also get things marketplace resellers cannot offer: HSA/FSA eligibility, a 1-year NW Immersion warranty on the complete system, freight coordinated to your address, live US-based support from our Pacific Northwest team, and the ability to visit our Vancouver, WA showroom (Thu–Sat, 10am–4pm PT) before or after you buy.

Wow! So impressed! We’ve had our duo plunge with the 1hp chiller for about a month. We spray the filter weekly and just replaced it for the first time. We’ve been using this daily and every time we get in it is exactly at our 45F temp. We have not used any water treatment yet and the water is crystal clear. This unit looks beautiful on our back covered porch and maintenance is a breeze- very happy with our purchase
