FAQ

The HD Pro is larger and round, designed for long, deep immersions, and fits two average-size adults. The HD Ultimate is more compact and vertical, with an integrated seat, ideal for individual use and smaller spaces.

The HD Ultimate is designed to fit through standard doors. The HD Pro does not fit through a standard door, so plan for adequate access for delivery and placement.

Both the HD Ultimate and the HD Pro comfortably fit users up to about 6'7". The HD Ultimate is designed for individual seated use, on a molded seat 12" (30 cm) off the floor: you sit instead of squatting. The taller you are, the more you tuck your legs to go under. The HD Pro offers more room to submerge and fits two people seated across from each other, if you're both average-size.

Yes. Eternal Ice tubs use standard 1/2" inlet/outlet fittings, so chillers with matching connections can be used.

The molded seat in the HD Ultimate sits 12" (30 cm) off the floor of the tub. That's the height that puts your shoulders under water once you sit down — no squatting, no bracing yourself: you sit, you breathe, the session starts. The seat is part of the molded shell, so there's nothing to install and nothing that shifts. The HD Pro is a round tub with no built-in seat: you sit on the floor, legs extended or crossed.

The tub and chiller are sold separately. Bundles including both are available (Ultimate or Pro).

Down to 2°C with the Eternal Ice Power Chiller.

The chiller can cool down to 2°C and heat up to 40°C.

Depending on your starting water temperature, it can reach low temperatures in a few hours. After that, it maintains your set temperature automatically.

The Eternal Ice Power Chiller is built to run every day — at home, at the gym, or anywhere else. When the compressor is cooling, it hums like a home air conditioner (≤ 52 dB); between cycles, the circulation pump remains audible. Most customers are comfortable using it in a garage, basement, home gym, outdoor deck, patio or dedicated room. If you're highly noise‑sensitive, we can help you choose the best placement.

The chiller is designed to run efficiently and maintain temperature once it reaches your set point.

Voltage: 110 V (standard). Power consumption: 900 W (cooling) and 1000 W (heating).

Yes. It includes a 50-micron coarse paper filter and an integrated ozone system.

Yes. Built-in Wi-Fi lets you control temperature through a mobile app, including scheduling. Once set up, you can control your chiller from anywhere — even outside your home Wi-Fi network.

It is designed to work with the HD Pro and HD Ultimate using standard 1/2" connections and the included hoses.

The shipment includes the chiller and the accessories listed on the product page, including hoses and filter components.

Yes, as long as the tub has standard 1/2" hose connections. It works best with rigid insulated tubs.

The Power Chiller can connect to an inflatable tub if it has compatible 1/2" hose fittings, but performance may be limited because inflatable tubs are poorly insulated.

Plug the chiller alone into a dedicated 15 A circuit (110 V), no extension cord. At startup the draw can briefly peak around 22 A — that's normal, and a healthy breaker tolerates it. If the breaker trips after the chiller has been running for a while, the running current is too high — almost always for one of two reasons: the condenser fins (the grille at the back) are dirty or airflow is blocked, making the compressor work harder; or the outlet voltage is low (extension cord, shared circuit), so the compressor draws more current to compensate. Gently clean the fins (soft brush or compressed air), keep at least 30 cm (12 in) of clearance around the unit, and check the connection. Still tripping? Call us: 418-809-0331 or ask us in the chat.

No. Place it where you want, connect the hoses, fill it, then set your temperature.

Connect the top fitting on the bath to the chiller outlet, and the bottom fitting on the bath to the chiller inlet.

Yes. Use Teflon tape on threaded connections to help create a proper seal.

Fill the tub first, confirm all fittings are secure, then turn the chiller on and set your temperature.

On the ground beside the tub, at the same level or lower — never on a deck or platform above it. The pump is not self-priming: placed higher, it has to lift water, loses its prime and draws in air instead of water, which stops proper circulation.

Yes. The tub can be used indoors or outdoors. For outdoor use in harsh winters, it is mandatory to unplug the chiller and store it indoors, and to use a de-icer when ice begins to build up. The chiller must never be left in temperatures below 0°C (32°F).

Yes, as long as ambient temperature is above 0°C (32°F). In winter it must be drained and stored in a heated area.

Technically it can, but we strongly advise against it: if the power goes out in deep cold, the water inside freezes and damages it — and that damage is not covered by the warranty (misuse). Store it for the season.

Drain it fully and store it in a heated area.

No — and technically it could, but we strongly advise against it: if the power goes out in deep cold, the water inside freezes and can damage it, and that damage isn’t covered by the warranty (it counts as misuse). Store it for the season: winter freeze protection is the De-Icer’s job.

No. Recirculation does not protect the chiller from freeze damage. Drain the chiller fully and store it indoors as soon as ambient temperatures approach freezing.

With the De-Icer plugged in, it is designed to activate automatically below 2°C and help keep the water from freezing solid. Without it, the water can freeze solid during extended sub-zero temperatures.

No. Insulation slows heat loss, but it will not prevent full freezing during sustained sub-zero weather. Use the De-Icer for daily winter use.

Yes. Eternal Ice Bath is based in Lévis, Quebec, and the tubs are designed for real Canadian winter conditions. With the De-Icer (your Winter Kit — free with any bundle), you can use your bath outdoors year-round, including in sub-zero weather.

It is designed to help prevent ice formation. It is a 1000 W unit with a thermostat that activates below 2°C and deactivates at 25°C. It's your Winter Kit: free with any bundle — unlock it on your bundle's page (Ultimate or Pro).

No. Do not leave the De-Icer in the bath or connected while you are in it. Unplug it before entering the water.

The De-Icer should not rest directly on inflatable walls or floors because it can damage the material. It is best used with rigid insulated tubs.

Ozone sanitation helps disinfect the water, and the 50-micron coarse paper filter helps remove particles. Keep the lid on when not in use to reduce debris.

Replace the filter as needed based on usage and water flow. If you notice reduced flow, it is time to change it.

Yes. Maintaining pH, alkalinity, and hardness helps support water quality and protect components, and helps reduce the need to change the filter.

Use the ozone system regularly to help maintain water quality. Frequency depends on usage. Each time the chiller starts, a 1-hour ozone cycle is automatically initiated.

Cold exposure carries real risk if misused. Start gradually, keep sessions short at first, and consult a healthcare professional if you have a medical condition or concerns.

No. Many people use cold exposure as part of a wellness routine. Start gradually and build consistency.

2–4 sessions of 2–5 minutes a week — about ten minutes of total cold is enough. Mood and energy: measurable from the very first session. Recovery: less muscle soreness within 24–96 h of training. Start short — even 30–90 seconds works — and build at your own pace.

Cold therapy is deliberate exposure to cold water. Many users use it to support recovery, energy, mood, mental resilience, and sleep. Results vary, and cold exposure is not a medical treatment.

Beginners should start with 1–3 minutes. Experienced users often stay 5–10 minutes. Start gradually, keep sessions controlled, and exit if you feel lightheaded, numb, or unwell.

Beginners often start around 10–15°C. Experienced users may prefer 2–5°C.

An ice bath provides full-body, consistent cold exposure that a shower cannot fully replicate. Cold showers are a useful starting point, but immersion gives more controlled and even exposure.

Yes, but commercial use has warranty implications. The warranty covers non-commercial use for the original consumer purchaser. Commercial use requires explicit prior written consent.

If goods are shipped into the EU, the refund policy outlines the applicable cancellation and return window and conditions.

A limited 2-year warranty covering cracks and material defects when used as intended and properly maintained. It covers parts: if a part is found defective, we ship it to you free of charge. It does not cover labour — installing or replacing the part is your responsibility.

No. We cover the part, not the work of installing it. In practice that usually amounts to very little: remote diagnosis is free and most parts (filter, hoses, fittings, seals) swap out in minutes, with our guidance by email or phone.

Two different things. The warranty does not apply at all to damage from improper installation, relocation, accidents, misuse or abuse, unauthorized modifications, neglected maintenance, or to surrounding surfaces and structures. And on a valid claim, labour stays on you: parts are covered, the installation work is not.

Email us or reach us in the chat: we diagnose remotely, at no cost. If a covered part is at fault, we ship it free of charge and walk you through the swap by email or phone — most parts (filter, hoses, fittings, seals) take minutes. Labour stays on you. Rather talk to someone? 418-809-0331.

If the defect is confirmed under warranty, we reimburse your documented shipping costs up to CAD $250. You arrange the shipment, we pay you back. And in many cases no return is needed at all: we sort it out remotely and send you the part.

Yes, in one specific case: leaving the chiller outside through winter is misuse. It can technically run in cold weather, but if the power goes out the water inside freezes and damages it — that damage is not covered. Store it for the season; the De-Icer is what keeps the bath water from freezing.

Slight fading can show up over the years, especially in full sun: that's normal for equipment that lives outdoors — the tub as well as the chiller housing — and it's purely cosmetic. It doesn't affect the seal, the insulation, the strength of the shell, or how the chiller runs — those stay covered against cracks and material defects.

The warranty applies to non-commercial use by the original consumer purchaser. Commercial use requires explicit prior written consent.

Our warranty and support apply to installations built with Eternal Ice components, hoses, and fittings as supplied. Custom or modified setups — homemade hoses, non-Eternal Ice fittings, custom plumbing, or altered configurations — can cause air intake, leaks, poor circulation, reduced efficiency, or premature damage, and our technical team may not be able to fully investigate or support them. Planning a custom setup? Tell us first — we'll tell you what stays covered and what doesn't.
