SISU Cold Plunge with 1 HP Signature Chiller – Premium Ice Bath System
The Best Cold Plunge With Chiller On The Market
Revitalize your wellness routine with the SISU Cold Plunge System, engineered for unmatched durability and efficiency. Perfect for both indoor and outdoor settings, our system integrates seamlessly into your lifestyle at an affordable price point. Using high-quality materials and advanced insulation technology, the SISU Cold Plunge guarantees a cold, refreshing experience every time.
The Grizzly Cold Plunge Tub: Our Base
Our system is built on the rotomolded Grizzly Cold Plunge, renowned for its exceptional insulation capabilities. With up to two inches of pressure-injected polyurethane foam, it ensures efficient cooling and impressive water temperature retention. Unlike most tubs, the SISU Plunge features a weatherproof, sealed lid that significantly enhances thermal efficiency, leading to considerable energy cost savings.
Key Features:
- Premium Insulation: Engineered with polyurethane foam and gasket-sealed lids for superior temperature retention and reduced energy consumption.
- Optimal Size: At 24” deep, the tub allows for full submersion up to the neck and is spacious enough to dunk your head if you’re feeling extra brave. We’ve had individuals up to 6’7” tall using the tub and can fully submerge comfortably.
- Portable: Weighing just under 100 lbs when empty, it is equipped with built-in molded handles for easy maneuverability.
- Convenient Draining: 3/4” standard Garden Hose Thread Connections for quick and easy draining.
- Easy Setup: Designed for simple setup without plumbing. Fill the tub with a hose and connect to a standard outlet.
Water Chiller for Ice Bath: SISU 1 Horsepower Signature Chiller
Transform your cold plunge experience with the SISU 1 HP Signature Chiller, engineered to cool water from 80°F to 45°F in about 2 hours —twice as fast as the competition. This powerhouse chiller ensures your plunge into icy cold water is always ready, featuring:
- Superior Cooling: Cools down to 39°F significantly faster than the competition.
- Advanced Filtration: Equipped with a 5-micron filter and UV sanitation to maintain water cleanliness.
- Effortless Setup: Quick Connection Fittings and operation on a standard 110V outlet simplify installation.
The chiller pump not only delivers clean, icy cold water on demand but also keeps the water clean, thanks to its advanced filtration system, ensuring a refreshing and hygienic cold plunge experience every time.
Cold Plunge Dimensions
- Exterior Cooler Dimensions: 60” length x 38.5” width x 31” height
- Weight: Tub only - 102 lbs empty, chiller weight - 45 lbs, total shipped weight - 250 lbs
How Are We Different?
Our SISU Plunge stands out for its superior design and efficiency. While many tubs struggle with poor insulation and flimsy foam lids, our system uses a robust, weatherproof lid similar to those found on top-tier coolers, ensuring water temperature is maintained consistently. This not only cuts down on energy costs but also enhances the overall experience. Additionally, unlike tubs with canvas-wrapped lids that are prone to bacterial growth in outdoor settings, our SISU Plunge remains clean and safe, making it a smarter choice for your wellness routine.
- High-Quality Construction: Uses a rotomolded cooler for durable, efficient insulation, outperforming the inflatable tubs of competitors.
- Superior Cooling: Equipped with a 1HP chiller, offering fast cooling compared to the common 1/2 HP chillers used by the competition.
- Optimal Temperature Retention: Features gasket sealing for enhanced insulation as opposed to a buckled lid without gasket sealing typically offered by the competition.
- Advanced Filtration and Sanitization: Includes a 5-micron filter and UV sanitation, competitors often only offer one or the other, not both.
Frequently Asked Questions
-
What is a cold plunge chiller?
A cold plunge chiller agitates water through a heat exchanger to maintain a consistent temperature, similar to an air conditioner but for water. This constant circulation ensures the water remains chilled and ready for a plunge whenever needed. -
What size chiller do I need for a cold plunge?
Typically, you need a chiller of at least 1/2 horsepower. However, in extremely hot climates, a 1 horsepower chiller is recommended to maintain a <45°F water temperature consistently. -
Can you use a water chiller for an ice bath?
Yes, a water chiller can be used for an ice bath. It maintains the water at a consistently low temperature, eliminating the need for actual ice. -
What does a cold plunge actually do to a body?
A cold plunge reduces muscle soreness and inflammation, enhances recovery through improved circulation, boosts the immune system, increases energy levels, and improves mental health by reducing stress. -
Do cold plunges burn fat?
Yes, cold plunges activate brown fat, which burns calories to generate heat, aiding in weight management. -
How long should you stay in a cold plunge?
The recommended duration is between one to three minutes. Beginners should start with shorter durations, such as 30 seconds, and gradually increase as they build tolerance. -
How often should you cold plunge?
It is recommended to cold plunge two to three times per week for optimal benefits and recovery. Start with fewer sessions per week and increase as your body adapts.

FAQs
Please read our FAQs page to find out more.
What are the benefits of cold plunging?
Cold plunging (cold water immersion) offers a cascade of benefits for both body and mind. Research shows it can:
• Improve Circulation & Muscle Recovery: The rapid constriction and dilation of blood vessels helps flush out inflammation and reduces muscle soreness. This process supports faster recovery and better cardiovascular efficiency.
• Boost Metabolism & Activate Brown Fat: Regular exposure can trigger brown fat activation, increasing your metabolic rate and enhancing insulin sensitivity—supporting healthy weight management when combined with a balanced lifestyle.
• Enhance Immune Function: Cold exposure can stimulate white blood cell production, with studies noting up to 29% fewer sick days when cold showers were taken consistently.
• Elevate Mood & Mental Clarity: The release of endorphins and norepinephrine during a cold plunge can improve your mood, reduce stress, and sharpen focus.
Remember: Always start slowly and consult a healthcare provider if you have underlying condition
Do I need ice for my cold plunge?
No—our cold plunge tubs come with powerful built-in chillers that maintain your set temperature, so there’s no need to add ice. Simply fill the tub, set your desired temperature, and let the chiller work its magic.
However, if you desire an extra frosty experience, you can add ice temporarily:
• Initial Cool-Down: A few ice cubes can help bring tap water down faster before the chiller takes over.
• Ultra-Low Temps: If you’re aiming for near-freezing water, a bit of ice can push the limits further.
• Backup Option: For models without a built-in chiller or during power outages, ice remains a viable option.
What temperature should I set my cold plunge to?
The ideal temperature depends on your experience and comfort:
• Beginners: Start at 50–59°F (10–15°C) for a gentle introduction.
• Intermediate Users: Once acclimated, try 41–50°F (5–10°C); many find around 45°F (7°C) to be the sweet spot.
• Advanced Users: Those well-adapted may venture into the high 30s°F (~4°C), but going below 39–40°F isn’t recommended for safety.
Pro Tip: Choose a temperature that gives you a sharp inhale but remains tolerable for 1–2 minutes. Start warmer and gradually dial it down as your body adapts.
How long should I stay in the cold plunge?
Even brief sessions can be effective:
• Start Short: For beginners, 30–60 seconds is a great starting point to build tolerance.
• Typical Session: Most users find 2–3 minutes to be the ideal duration to trigger the benefits without overdoing it.
• Maximum Duration: Generally, sessions shouldn’t exceed 5 minutes continuously in very cold water to avoid potential risks like numbness or excessive core temperature drop.
Always listen to your body—if you experience prolonged shivering, dizziness, or discomfort, exit the tub and warm up.
Do I need plumbing to set up a cold plunge?
No special plumbing is required. Our cold plunge tubs are self-contained with built-in pumping and filtration systems. Simply fill the tub with a standard garden hose and plug it into an electrical outlet. This plug-and-play design means you can set it up on a deck, patio, garage, or gym room without any remodeling or the need for a plumber.
How often should I change the water?
Routine water maintenance is key:
•Standard Use:Change the water every 2–4 weeks if you use the tub frequently.
•With Filtration & Sanitation:If you utilize built-in filtration and sanitation methods (like ozone or UV purification), you might extend the water change cycle to every 2–3 months.
•Without Sanitizers:If you prefer pure water with no additives, you may need to change it more often (about every 2 weeks).
Watch for signs like cloudy water or odor. A simple drain and refill will ensure a fresh, inviting plunge every time. See our Maintenance Guide for more details.
Can I use my cold plunge indoors?
Yes—you can use a cold plunge indoors. Here are some tips:
• Choose a Suitable Spot: Place the tub on a water-resistant surface (tile, concrete, etc.), ideally near a floor drain, and consider using a waterproof mat or tray.
• Ensure Proper Ventilation: Cold water can cause condensation; open a window or use a fan/dehumidifier to manage humidity.
• Check Floor Support: A filled tub is heavy (700–1000+ lbs), so ensure your floor can support it, especially on upper levels.
Indoor use offers privacy and protection from weather extremes, making it a convenient option for many.
Do your cold plunges include a chiller?
Many of our premium cold plunge models include a built-in chiller unit that maintains your desired temperature (often down to 39°F).
If you prefer a model without an integrated chiller—or already have a tub—we also offer standalone chiller units that can be purchased separately. This gives you the flexibility to customize your cold therapy setup based on your needs and budget.
Chiller vs. Ice: Traditional ice baths are less consistent and more costly over time. An electric chiller provides steady, precise control for a reliable, on-demand cold plunge experience.
Do you offer free shipping?
Yes, we offer free shipping on all orders within the contiguous United States. This means no hidden freight charges at checkout. (For Alaska or Hawaii, please contact us as additional fees may apply.)
Do you ship internationally?
Currently, we ship only within the United States. Our cold plunge tubs are designed to meet U.S. electrical standards (240V).
If you’re outside the U.S. and interested in our products, please contact us to discuss potential options or to receive updates on future international availability.
What payment methods do you accept?
We accept all major credit and debit cards (Visa, MasterCard, American Express, Discover, Diners Club) along with popular digital wallets such as:
• PayPal
• Apple Pay & Google Pay
• Venmo (on supported devices)
• Shop Pay (which also offers installment options)
Our checkout is secure and encrypted, ensuring a safe shopping experience.
Do you offer financing?
Yes—we offer financing through Shop Pay Installments. This option lets you spread the cost over time rather than paying the full amount upfront. During checkout, if your cart qualifies, you’ll see available installment plans (some interest-free if paid within a set period). Approval is quick and typically does not affect your credit score.
Can I cancel or modify my order?
If your order hasn’t shipped yet, we can typically modify or cancel it for a full refund. Please contact us as soon as possible with your order number and desired changes (such as updating the shipping address or model). Once an order has shipped, modifications become more complex and may require a return. The sooner you reach out, the better we can assist.
What is your return policy?
We offer a 30-day return window from the date of delivery for items in new, unused condition and in their original packaging. If you experience any issues (such as damage or missing parts), contact us immediately so we can resolve it. For standard returns, return shipping costs are typically the customer’s responsibility unless the return is due to a defect. Once we receive and inspect the item, we’ll issue a refund to your original payment method. For full details, please refer to our Refund Policy.
Is there a warranty on your cold plunges?
Yes—all the cold plunge tubs we offer come with a manufacturer’s warranty covering defects in materials and workmanship. Standard coverage is typically 1 year, though certain models or components may have extended warranties. Warranty specifics are provided on the product page and in the accompanying user manual. This warranty covers functional defects (like chiller or structural issues) but does not include damage from misuse or normal wear-and-tear.
