EONIX Upgrade 1/3 HP Cold Plunge Chiller
Origins and purpose: A compact cold plunge chiller designed for smaller tubs and home setups. Best for: beginners or spaces with limited capacity. Key strengths include a precise temperature control within 1°F and a built-in fine-mesh filter to reduce debris. The model supports up to 79 gallons (300 L) and uses a marine-grade evaporator. Caution: capacity may limit longer sessions in larger tubs; plan for smaller or mid-sized tubs accordingly.

Overview: A higher-capacity option with faster cooling compared to 1/3 HP models. Best for: larger tubs (roughly 79–105 gallons) and frequent cold therapy. Features include a built-in filtration system that traps debris, reducing maintenance, and an LED touch screen with remote control. Limitation: higher power draw may be a consideration for energy-conscious setups.
AS ColdPlunge Ice Bath Chiller (1/3HP)
Designed for consistent, ice-free cooling down to 42°F. Best for: home users seeking reliable daily ice-free plunges with flexible tub compatibility. It includes a built-in pump and a washable metal filter, reducing disposable filter waste. Caution: check tub inlet/outlet compatibility if using non-standard plumbing.

Buying Guide
What size tub do you plan to chill? If you have a small to mid-size tub, a 1/3 HP model may be sufficient. For larger tubs or frequent recovery sessions, a 1/2 HP option can reduce cooling time and maintain temperature more reliably. Consider capacity ranges (gallons) and whether a tub is already setup for cold therapy or if you need a complete kit with tub, hoses, and filter.
Do you want an integrated filtration system? Built-in filters reduce debris and maintenance but verify filter type and ease of cleaning. For low-maintenance setups, models with reusable metal filters are advantageous. If you platter for continuous use in a busy home gym, a robust filtration and remote control features add convenience.
Is space a constraint? Compact 1/3 HP chillers fit smaller spaces, while larger 148-gallon kits demand more room. If you’re in a warm climate, consider models designed for outdoor or high-ambience operation; some units are optimized for hot environments to maintain consistent temperatures.
Temperature targets and accuracy: Most chillers target near 41–42°F, with some offering tighter variance (1°F). Decide whether you need ultra-precise control or if a stable, ice-free temp suffices for your routine.
Maintenance and longevity: Look for corrosion-resistant components and easy-to-clean filtration. Reusable filters and accessible filter housings reduce ongoing costs and downtime. Consider the lifetime maintenance burden when comparing models with disposable versus reusable elements.
Frequently Asked Questions
- What size chiller do I need for a 100-gallon tub? A 1/2 HP chiller is typically sufficient to reach and maintain temperatures in large volumes, though exact performance depends on tub design and ambient temperature.
- Do these chillers require ice? No. Most units are designed to cool water to 41–42°F without adding ice, though some setups may use ice as a supplement in extreme conditions.
- Can I use a cold plunge chiller with any tub? Many models are universal with standard inlet/outlet fittings, but verify port size (commonly 1/2 inch) and tub compatibility before purchase.
- How often do I need to replace filters? Some models use washable filters; others use disposable options. Washable filters reduce ongoing costs and waste when cleaned regularly.
- Is remote control really useful? Remote control provides flexibility to adjust temperature without getting in or near the tub, especially for garage or outdoor setups.
- Which chiller is best for hot climates? Pro or high-capacity models with stronger cooling power generally perform better in warm environments and outdoor spaces.
