The Flagship Hot & Cold Plunge from NW Immersion

The Immersion Tub Luxury Hot & Cold Plunge is NW Immersion’s flagship recovery system, created for people who want professional-grade cold therapy, warm soaking, and contrast therapy without the complexity of external chillers, complicated plumbing, or constant ice runs.

At the heart of the system is a powerful integrated 2HP chiller and heater capable of cooling water down to 32°F and heating up to 113°F. That means one tub can support cold exposure, ice bath sessions, warm soaking, and sauna-to-plunge contrast therapy from a single, beautifully finished system.

The interior is intentionally spacious, with a 316 stainless steel basin designed for comfort, durability, and full-body immersion. Unlike many compact cold plunges, the Immersion Tub comfortably accommodates users up to 6'5"+, making it an ideal choice for taller users, athletes, and anyone who wants a less restrictive plunge experience.

The exterior is finished in architectural red cedar, giving the tub a warm, furniture-like presence that feels appropriate in luxury homes, backyard retreats, gyms, spas, recovery rooms, and indoor or covered outdoor wellness spaces.

With WiFi control, integrated display, triple filtration, ozone sanitation, and service-friendly mechanical access, the Immersion Tub is designed not only to look beautiful, but to be easier to own, maintain, and use every day.

True Hot & Cold Therapy in One System

Cold plunge, ice bath, warm soak, or contrast therapy — the Immersion Tub gives you both ends of the temperature spectrum in one self-contained system.

Powerful 2HP Cooling

The integrated 2HP chiller is designed for powerful cold plunge performance and can cool water down to 32°F without requiring bags of ice or an external cooling unit.

Heats up to 113°F

When you want warm soaking, contrast therapy, or a gentler recovery session, the built-in heating system raises water temperature up to 113°F.

Built for Taller Users

With a spacious stainless steel interior, the Immersion Tub is designed for comfortable full-body immersion and accommodates users up to 6'5"+.

Plug-and-Play 120V Setup

No external chiller. No permanent plumbing. No complex installation. The Immersion Tub operates on a dedicated 120V / 15A outlet.

Premium Cedar + Stainless Steel Construction

A 316 stainless steel interior provides durability and cleanability, while the red cedar exterior adds warmth, texture, and architectural presence.

Cleaner Water Management

Triple filtration and ozone sanitation help support cleaner water with less daily maintenance.

WiFi Control Included

Adjust and monitor temperature from your smartphone using the integrated WiFi control system.

Hot, Cold & Contrast Therapy

One Tub. Two Temperature Extremes. Endless Rituals.

The Immersion Tub is designed for people who want more than a basic cold plunge. With both powerful cooling and integrated heating, it supports a wider range of wellness routines.

Cold Plunge

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

Ice Bath

For those who want a more intense cold exposure experience, the 2HP chiller can cool water down to 32°F without requiring bags of ice.

Warm Soak

Use the integrated heater to bring water up to 113°F for warm soaking, relaxation, or gentler recovery sessions.

Contrast Therapy

Move between sauna, cold plunge, and warm soak rituals to create a complete contrast therapy experience at home.

Wellness note: The Immersion Tub 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.

Designed for Real Full-Body Immersion

More Space. More Comfort. Better Daily Use.

Many cold plunges are built around compact dimensions, which can leave taller users feeling cramped or restricted. The Immersion Tub was designed differently.

With an interior length of 58", width of 31.6", and depth of 24.6", the tub offers generous space for full-body immersion while maintaining a refined footprint suitable for residential and commercial wellness environments.

Whether you are 5'6", 6'2", or 6'5"+, the Immersion Tub is designed to feel more comfortable, stable, and usable as part of a daily routine.

Built for Ownership, Not Constant Maintenance

Cleaner Water. Easier Access. Smarter Design.

The Immersion Tub is engineered as a complete self-contained system, with integrated cooling, heating, filtration, ozone sanitation, and service-friendly access panels.

The triple filtration system helps capture debris, while the ozone sanitation system supports water cleanliness between changes. Easy-access mechanical compartments make routine care and servicing more straightforward, helping reduce friction in long-term ownership.

Instead of piecing together a separate tub, chiller, hoses, filters, and external controls, the Immersion Tub gives you one complete, integrated system designed to work together.

Immersion Tub Recovery System

Complete all-in-one hot and cold plunge designed for indoor or outdoor wellness spaces.

Integrated 2HP Chiller & Heater

Powerful cooling and heating system capable of cooling down to 32°F and heating up to 113°F.

316 Stainless Steel Interior

Corrosion-resistant stainless steel basin designed for durability, comfort, and long-term performance.

Architectural Red Cedar Exterior

Premium cedar cladding adds natural warmth and a refined design presence for home and commercial wellness environments.

WiFi App + LED Control System

Control temperature and system settings from your smartphone or directly from the integrated display.

Triple Filtration System

Water filtration designed to help maintain cleaner water with easier routine care.

Ozone Sanitation System

Built-in ozone sanitation helps support water cleanliness and reduce maintenance demands.

Premium Insulated Cover

Installation & Setup

Plug-and-Plunge Simplicity

The Immersion Tub is designed for a streamlined installation experience. Because the chiller, heater, filtration, ozone, and controls are built directly into the system, there is no external chiller to place, no hoses to connect, and no permanent plumbing required.

For best performance and longevity, place the tub on a flat, waterproof, load-bearing surface with proper drainage, airflow, and service clearance. Outdoor installations should be covered or partially protected whenever possible.

Quick Setup Process

  1. Position the tub on a level, load-bearing surface with proper clearance.
  2. Confirm the GFCI plug and electrical connection are protected from direct rain, heavy spray, and pooling water.
  3. Make sure all vents, access points, and chiller airflow areas are clear.
  4. Connect the drain assembly using Teflon tape and ensure the valve is closed.
  5. Rinse and wipe down the stainless steel interior before filling.
  6. Prepare the integrated filter housing and fill the filter chamber with water.
  7. Fill the tub to at least 2" above the outlet level.
  8. Open the internal valve and allow the water to settle for approximately 20 minutes.
  9. Plug into a dedicated 120V / 15A GFCI-protected outlet and power on.

Recommended Placement & Airflow

Protect Your Investment with Proper Placement

The Immersion Tub Luxury Hot & Cold Plunge is designed for indoor or outdoor use, but for best long-term performance and protection, we strongly recommend placing it in a covered or partially protected area rather than leaving it fully exposed to the elements.

Like any system with integrated electrical and chiller components, proper placement, airflow, and freeze protection are important for safety, performance, and longevity.

For best results:

  • Place the tub under a covered patio, pergola, sauna shelter, wellness structure, 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 compartment, vents, and access panels clear of dust, leaves, debris, snow, towels, storage bins, or anything that could restrict airflow.
  • Do not block the vents or mechanical access points.
  • Maintain the recommended side and rear clearances so the system can breathe and be serviced properly.
  • Place the tub on a flat, waterproof, 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 and temperature management help the chiller operate efficiently, reduce unnecessary strain on the system, and help protect the electrical and mechanical components over time.
