Collection: Cold Plunge Chillers

A cold plunge chiller — sometimes called a cold plunge water chiller or ice bath chiller unit — is a self-contained refrigeration device that connects to your tub via two quick-connect hoses: one inlet, one outlet. It pulls water through a refrigeration cycle and returns it chilled to your target temperature, holding it automatically without any ice, refilling, or monitoring. The integrated heater lets you set a warm temperature for contrast therapy or recovery soaks.

Both the 0.8 HP and 1.0 HP units are rated by the manufacturer for tubs up to 135 gallons. The difference is cooling speed: the 0.8 HP cools 1–3°F every 30 minutes; the 1.0 HP cools 1–3°F every 20 minutes. For smaller tubs (under 80 gallons) in climate-controlled indoor spaces, the 0.8 HP is plenty. For larger tubs, outdoor setups, or when you want the water ready faster, choose the 1.0 HP. When in doubt, size up — a chiller running with headroom runs quieter and lasts longer. Call us and we'll match you to the right unit: (888) 500‑5675.

The formula: BTUs needed = (Gallons × 8.33 × Temperature Drop °F) ÷ Hours to reach target. Example: 100-gallon tub, dropping from 72°F to 50°F in 4 hours = (100 × 8.33 × 22) ÷ 4 = 4,582 BTUs/hr required. Insulation quality and ambient temperature affect real-world results — a covered, insulated tub with a lid pulls significantly less load than an open stock tank in a warm garage.

Ice typically runs $8–$15 per session when you account for bags, sourcing time, and frequency. A cold plunge chiller uses roughly $0.30–$1.00 in electricity per session depending on your utility rate and starting water temperature. At 5 sessions per week, that's a break-even of roughly 14–18 months versus ongoing ice costs at mid-range pricing — after which you're saving over $2,600 per year compared to buying ice, while plunging on demand at a consistent temperature every time.

Both the 0.8 HP and 1.0 HP chillers run on standard 120V household current with a built-in GFCI plug — no dedicated circuit or electrician required for most installs. The outlet should be within cord reach of the unit and not shared with other high-draw appliances on the same circuit. Commercial or outdoor installations with long runs should verify voltage drop with a licensed electrician.

Yes, in most cases. This cold plunge chiller attachment connects via two quick-connect hoses included in the box — you'll need two compatible ports on your tub, one inlet and one outlet. Many stock tanks, purpose-built cold plunge tubs, and chest freezer conversions are compatible. Looking for a tub that comes with the chiller already matched? See our cold plunges with chillers — pre-paired combos are a common choice. If you already have a tub, send us the model or a photo and we'll confirm compatibility before you buy: (888) 500‑5675.

Yes. Both the PRO and Premier units include an integrated resistance heater in addition to the cooling compressor. The heating range reaches approximately 98–104°F, which supports contrast therapy protocols — cycle from cold immersion to a warm soak in the same tub without a separate device. The WiFi app lets you schedule temperature changes in advance so the water is at the right temperature before you step in.

Both PRO and Premier units use replaceable 20-micron filter cartridges. Rinse or replace every 4–6 weeks under regular use (3–5 sessions per week), or sooner if the water appears cloudy. Premier units include an upgraded two-stage filtration system with longer service intervals. Both units also include an automated ozone sanitation system that helps keep the water clear between filter changes. Two replacement filters ship in the box so you're covered out of the gate.

Chillers ship via FedEx or UPS Ground to the 48 contiguous US states at no additional charge — no freight truck, no liftgate required. Delivery is standard parcel service to your door. Estimated transit time is 3–7 business days after your order is processed. We do not currently ship to Alaska, Hawaii, or international addresses.

Cold water immersion is not appropriate for everyone. If you have cardiovascular disease, arrhythmia, uncontrolled hypertension, are pregnant, have Raynaud's syndrome, or have a history of epilepsy or seizure disorders, consult your physician before use. This is not an exhaustive list. When in doubt, your doctor is the right first call. Our team is happy to answer equipment questions: (888) 500‑5675.

Returns are accepted within 30 days of delivery. A 20% restocking fee applies, and the customer is responsible for return freight costs. Units must be returned in original, uninstalled condition in original packaging. If your unit arrives damaged or defective, contact us within 48 hours of delivery with photos of the damage and we will arrange a replacement or full refund at no cost to you.
