Cold Plunge Chiller

No More Ice. Consistent Cold. On Your Schedule.

Ice baths work — but buying, hauling, and storing ice for every session is an obstacle that keeps most people from doing them consistently. The PlungeBox 1/2HP Water Chiller Pro removes that friction entirely. Connect it to your PlungeBox, set your target temperature through the app, and your cold plunge is ready whenever you are — no ice run required.

The chiller cools your water down to 35°F and holds it there with precision. Bluetooth and Wi-Fi connectivity means you can schedule sessions in advance, adjust temperature remotely, and monitor the system from your phone. The touch screen panel gives you direct local control at the unit. With a built-in water pump, 20-micron filtration, and ozone sanitation running continuously, your water stays clean between sessions without manual maintenance.

For anyone plunging more than a few times a week, the math is straightforward: at 5 sessions per week using 15–40 pounds of ice each time, the chiller pays for itself in 3–4 months. After that, you're saving both money and the time it takes to manage ice — and your cold plunge becomes a permanent, reliable part of your recovery protocol rather than something you do when the stars align.

35°F

Minimum Temperature

Precision chilling to 35°F — held continuously, not just on initial cooldown. The same temperature every session, every time.

Chiller Technology

Four Systems. One Unit. Zero Compromises.

The Chiller Pro combines refrigeration, filtration, sanitation, and smart control in a single compact unit that connects directly to your PlungeBox.

🧊

1/2HP Refrigeration System

A 1/2-horsepower refrigeration compressor drives the cooling capacity — powerful enough to reach 35°F and maintain target temperature through repeated sessions. At typical room temperature (77°F) with the chiller set to 46°F, power consumption runs 1.4–1.8 kWh per day, equivalent to roughly $0.49–$0.63 in daily electricity cost.

💧

20-Micron Filtration + Ozone Sanitation

A built-in 20-micron filter catches particulate matter in the water, while integrated ozone sanitation continuously breaks down bacteria, algae, and organic contaminants. The result is water that stays clear and clean for extended periods between changes — without chemical additives or manual treatment.

📱

Bluetooth + Wi-Fi App Control

Connect via Bluetooth for close-range control or Wi-Fi for whole-home and remote access. The companion app lets you set target temperatures, schedule sessions in advance, and monitor the chiller without being near the unit. Wake up to a 38°F plunge already waiting — no standing by while it cools down.

BLUETOOTH + Wi-Fi · APP SCHEDULING · REMOTE CONTROL

🖥️

Touch Screen Control Panel

A built-in touch screen on the unit itself gives you direct local control without needing your phone. Set temperature, check status, and manage sessions right at the chiller. Two control methods means the unit is always usable regardless of app or connectivity status.

Water Quality System

Clean Water Without the Chemistry.

Cold plunge water quality is a genuine concern with repeated use — warm water grows bacteria fast. The Chiller Pro solves this with two independent systems working continuously: a 20-micron mechanical filter that removes particulate matter, and integrated ozone sanitation that breaks down bacteria and organic contaminants at the molecular level. No chlorine, no bromine, no treatment chemicals.

Built-in ozone sanitation eliminates bacteria, algae, and organic contaminants
Continuous circulation via built-in water pump keeps water moving
No chemical additives required for water hygiene

Ice Cost Savings

The Chiller Pays for Itself in 3–4 Months.

If you're plunging seriously — 5 sessions a week — you're spending $20–$50 on ice every week. That's $1,000–$2,500 per year on ice alone, not counting the time spent buying and hauling it. At 5 sessions per week using 15–40 pounds of ice per session at typical prices, the Chiller Pro recoups its cost in roughly 3–4 months. After that, your cold plunge runs on electricity costing less than a dollar a day.

5 sessions/week with 15–40 lbs of ice per session = $1,000–$2,500/year on ice
Chiller break-even: approximately 3–4 months at 5 sessions/week
Daily electricity cost: ~$0.49–$0.63/day at US average rates
Eliminates ice buying, hauling, and storage completely

3–4 Month Payback ~$0.50/Day to Run No Ice Required

Setup Guide

Connect, Fill, Chill. First Session in Minutes.

Position the Chiller

Place the Chiller Pro near your PlungeBox — within hose reach. The unit is compact at 42×30.5×35.5cm and can sit alongside or behind most PlungeBox setups. Ensure it's on a level, stable surface near a grounded 110V outlet.

Connect the Hoses

Attach the included insulated hose set between the chiller's inlet/outlet ports and your PlungeBox using the provided hose connectors and seal rings. Hand-tighten the seal rings to ensure leak-free connections — no tools required.

Fill Your PlungeBox with Water

Fill your PlungeBox tub to the recommended water level before starting the chiller. The pump circulates water from the tub through the chiller and back — the tub needs to be filled first for the system to work correctly.

Pair the App & Set Your Temperature

Download the PlungeBox app, connect via Bluetooth or Wi-Fi, and set your target temperature. Use the touch screen on the unit or the app — both give full control. Set a schedule for your first session or start cooling immediately.

Wait for Temperature & Plunge

Initial cooldown time depends on starting water temperature and your target. The app shows live temperature so you know exactly when you're ready. From that point forward, schedule sessions in advance and step in whenever it's time.

The Numbers

Ice vs. Chiller — The Math Is Clear

For anyone plunging regularly, the question isn't whether a chiller is worth it. It's how quickly it pays for itself.

💸

3–4 Month Payback

At 5 sessions per week using 15–40 pounds of ice per session at ~$3/10 lbs, the Chiller Pro recoups its full cost in approximately 3–4 months. For daily plungers, the payback is even faster — and after break-even, every session is essentially free to run.

⚡

~$0.50/Day to Run

At US average electricity rates and typical operating conditions (77°F ambient, chiller set to 46°F), daily energy consumption runs 1.4–1.8 kWh — approximately $0.49–$0.63/day. That's less than the cost of a bag of ice, every day, indefinitely.

💳

HSA/FSA Eligible

The PlungeBox 1/2HP Water Chiller Pro may qualify for HSA/FSA purchase through Truemed for customers with qualifying medical conditions. Using pre-tax health dollars typically saves 25–35% on average. Eligibility is confirmed through Truemed's qualification process at checkout.

Common Questions

Frequently Asked Questions

Everything you need to make a confident decision about the Chiller Pro.

The PlungeBox 1/2HP Water Chiller Pro is compatible with both the PlungeBox Standard and the PlungeBox PRO. All necessary connection hardware is included — hose connectors, seal rings, and the insulated hose set. No additional fittings or adapters are required for either PlungeBox model.

The Chiller Pro cools water down to a minimum of 35°F (1.7°C). Unlike ice baths that start cold and warm up quickly, the chiller actively maintains your target temperature throughout the session. You can set your precise target anywhere between 35°F and ambient temperature and the system will hold it there.

At typical operating conditions — 77°F ambient room temperature with the chiller set to 46°F — the unit consumes approximately 1.4–1.8 kWh per day. At the US average electricity rate of $0.35/kWh, that's roughly $0.49–$0.63 per day. Actual cost varies with your target temperature and local electricity rate, but most users find daily operating cost well under $1.

For someone plunging 5 times per week using 15–40 pounds of ice per session at approximately $3 per 10 pounds, the chiller recoups its cost in about 3–4 months. After that, each session costs only the electricity to run the chiller — roughly $0.10–$0.15 per session at typical usage. For daily plungers, the payback period is even shorter.

The Chiller Pro has two built-in water treatment systems. The 20-micron mechanical filter removes particulate matter as water circulates through the unit. Integrated ozone sanitation continuously eliminates bacteria, algae, and organic contaminants without chemicals. Most users can go several weeks between full water changes without any chemical treatment. You should still perform periodic water changes — follow the manufacturer's maintenance guidelines in the instruction manual.

Both. The Chiller Pro connects via Bluetooth for close-range control and Wi-Fi for whole-home and remote access. Wi-Fi connectivity means you can adjust the temperature or start a session from outside your home — useful for scheduling a cold plunge before you get back from training. The built-in touch screen panel also provides full local control without the app.

The Chiller Pro runs on standard 110V household current at 500 watts. The US plug (110V) power cable is included. It plugs into any standard grounded outlet — no dedicated circuit or special wiring is required. Place it near a grounded outlet within hose reach of your PlungeBox.

Initial cooldown time depends on starting water temperature, target temperature, ambient room temperature, and your PlungeBox's water volume. The app shows live water temperature so you always know exactly where you are. For best results, schedule your session in advance through the app so the chiller has time to reach your target temperature before you're ready to plunge.

The PlungeBox 1/2HP Water Chiller Pro may qualify for HSA/FSA purchase through Truemed for customers with qualifying medical conditions. Cold water immersion therapy has documented medical and rehabilitative applications supporting potential eligibility. Eligible customers typically save 25–35% using pre-tax health dollars. Eligibility is determined through Truemed's qualification process at checkout.

The Chiller Pro measures 42 × 30.5 × 35.5 cm and weighs 25 kg (approximately 55 lbs). It has a compact footprint that fits alongside most PlungeBox setups in a home wellness space, garage, or patio. The unit should be positioned on a level, stable surface near a 110V outlet and within hose reach of your PlungeBox tub.
