Recover faster, feel sharper, and embrace the cold with a professional-grade ice bath that sets up in minutes.

♨️ Product Overview

The NetSpa Järvi Ice Bath is a complete cold water therapy system that combines a premium Drop-Stitch inflatable basin with a powerful 5kW Spawer chiller unit, recirculation pump, and everything you need to start cold plunging straight out of the box. Designed for athletes, fitness enthusiasts, and wellness seekers, the Järvi delivers precise temperature control down to 3°C without the hassle of buying and hauling bags of ice for every session.

📋 What’s Included

Everything you need is in the box — the Järvi arrives as a complete system across three packages:

Box 1 – Ice Bath Basin:

✅ Inflatable Drop-Stitch ice bath basin

✅ Thermal cover with clip safety buckles

✅ 2 × connection pipes (250 mm, Ø32 mm) with inlet/outlet caps

✅ Antibacterial cartridge filter with filter support

✅ Manual air pump with pressure gauge

💰 Running Costs

Energy Rate Used: £0.2769/kWh (Ofgem Price Cap, Q1 2026 — January to March 2026)

The Järvi’s 5kW chiller uses Full Inverter technology, meaning it adjusts its power output to match actual cooling demand rather than running at full capacity continuously. The maximum power consumption is 1.35 kW, but typical consumption during maintenance cooling will be significantly lower.

Cost at Maximum Power Consumption:

Metric	Value
Maximum power draw	1.35 kW
Cost per hour (at max power)	£0.37
Cost per hour (typical maintenance)	Varies by ambient temperature and insulation

Estimated Session Costs (at max power consumption):

Scenario	Duration	Max Cost
🏠 Pre-cooling water before a session	2 – 4 hours	£0.74 – £1.49
🧖 Maintaining temperature (per hour)	1 hour	Up to £0.37

Energy Efficiency Advantage:

The chiller’s COP (Coefficient of Performance) of up to 5.2 means that for every 1 kW of electricity consumed, it delivers up to 5.2 kW of cooling energy. This makes it vastly more efficient than traditional cooling methods and eliminates the ongoing cost of purchasing ice (typically £3–£5 per 10 kg bag, with 30–50 kg needed per session).

💡 Compared to buying ice for each session, the chiller typically pays for itself within months of regular use.

⚠️ Actual running costs depend on ambient temperature, target water temperature, session frequency, and insulation. Costs shown are based on maximum power consumption and represent upper estimates.

🛠️ Setup & Installation

The Järvi is designed for straightforward setup without specialist tools or professional installation.

🌡️ Benefits of Cold Water Therapy

Physical Benefits

✅ Muscle Recovery – Cold immersion reduces muscle soreness and accelerates recovery after intense exercise by constricting blood vessels and reducing inflammation.

✅ Inflammation Reduction – Cold exposure constricts blood vessels, helping decrease swelling and pain related to injuries or physical exertion.

✅ Improved Circulation – Cold water stimulates blood flow, promoting better oxygenation of muscles and tissues for faster recovery.

✅ Immune System Support – Regular cold exposure has been linked to increased norepinephrine production (200–300% increase), which supports immune function.

Mental & Emotional Benefits

✅ Stress Reduction – Cold exposure stimulates endorphin production, the body’s natural feel-good hormones, helping lower stress levels.

✅ Enhanced Mood – Cold triggers the production of dopamine and serotonin, neurotransmitters that help combat low mood and boost motivation.

✅ Mental Resilience – Facing the cold builds mental toughness, pushing physical and psychological limits and enhancing self-confidence.

✅ Better Sleep – Cold therapy lowers core body temperature, promoting deeper, more restorative sleep.

✅ Focus & Mental Clarity – Cold water stimulates the nervous system and improves blood flow to the brain, enhancing concentration and reducing mental fatigue.

❓ Frequently Asked Questions
