Frequently Asked Questions

We recommend starting at temperatures between 55-60°F, for anywhere from 3-9 minutes. At first it's definitely going to be more of a challenge so easing into it is a great way to get started.

You eventually want to work your way down to 50°F or below for closer to 10 minutes. Anything above 10 minutes at those temperatures isn't recommended.

It's important to challenge yourself while knowing your limits!

Plunging into cold water first thing in the morning helps trigger chemical reactions throughout the body that increase energy and mental alertness. It's also great to relieve that morning pain and stiffness. Another great time is ∼30 minutes after an intense workout (like cardio) to reduce inflamation and flush lactic acid.

BUT for bodybuilders cold plunging after a workout isn't recommended. It will "kill your pump" by constricting blood vessels, so wait a few hours after your lift, do it before for increased energy, or do it on your rest days to reduce soreness.

For most peope the shock of the cold will cause them to breathe heavy and fast. To reap the most benifits focus on:

1. Before jumping in, take slow, deep breaths.

2. When you're ready, enter the plunge on an exhale. Having empty lungs allows for as much oxygen to enter when the shock hits.

3. Maintain a slow and steady breath as you're in the cold. Your body trick you into short, fast, shallow breaths, so it's very important to slow things down to get the most out of your cold plunge.

4. Throughout the plunge continue to focus on your breathing. Direct your mental energy toward staying in control. With more experience, this practice can deliver a sense of peace and well-being, much the way meditation can.

5. If you feel anxious, slow your breathes down and focus on a longer exhale than inhale.

If your new to cold plunging, we recommend 3 times per week to see how your body reacts to the new stimulus. It's totally okay to do it everyday too and should be something built into your routine. Many people recommend doing it right in the morning to jumpstart their day.

People with:

1. High Blood Pressure

2. Heart Disease

3, Asthma

4. Circulatory problems like peripheral artery disease

Please consult with a healthcare professional first if you are unsure.

The tub can be inflated and setup in under 15 minutes. Make sure the pump is connected to the inflate side and inflate to 10psi.

Our cold plunge tubs are made with military grade dropstitch material. The same material as inflatable paddle boards so there's no worry for it being stored outside. When inflated you can sit on the side of the tub to give a reference for its durability and many are suprised to find out it's inflatable.

You can fill each of the tubs to your desired amount but when filled to the maximum line it's:

FujiTub Solo - 60 gallons

FuiTub Double - 95 gallons

Fujitub 4 Person - 449 gallons

Not often. The water can last for months at a time with up to date filter maintenance. It's recommended to change the water once a month for heavy use with multiple people and once every 2 months for moderate to light use. We encourage you to keep it covered with the provided inflatable lid to prevent any debris from entering the water.

With our 20 micron filter and built in ozone sanitation from the chiller unit, your water is ensured to be cleaned even if multiple people are going to be using it. 100% of the water is cycled through the filters every 15-25 minutes, making it the perfect option for sports teams or gyms where multiple people will be immerging into the water after each other.

If you're not using our chiller that keeps the water clean, please use a spa/pool sanitation kit.

You have the option tp open the water outlet and drain it that way, or connect a hose to direct the water drainage where you would like it to go.

Our chiller can cool the water down to 37°F and heat it up to 107°F.

Depending on the outside temperature, times may vary, but after various tests it's been around 10-12° per hour. This is twice as fast than other iceless cold plunges on the market.

Also keep in mind that our tubs are insulated. By turning off the chiller and putting on the lid, you can expect to come back to your cold tub the next day with water much colder than if you were to refill it. Same if it was heated. This allows for a much faster cooling/heating time after the first fill of your tub.

If desired, the cool down process can be sped up by adding ice while filling the tub with water.

Yes. With our partnered app Smart Life you can control various things remotely including setting the water temperature and even setting an automated time for when you want the chiller to start cooling each day.

The chiller shouldn't operate in conditions below 35°F as the unit would be at risk of freezing, causing severe damage. It also shouldn't operate in temperatures above 101°F. Our warranty does not cover damage due to use in conditions outside of this operating range.

The chiller requires a standard US 120v/60hz power supply on a 15 amp circuit. We recommend that this circuit be dedicated for the chiller as it may trip the circuit breaker if shared with other large appliances such as a refrigerator. The chiller is not multi-voltage and cannot be used in countries that do not supply 120v/60hz power.
However, if you're located outside of Canada/USA and would like one of our tubs with chillers, contact with us so we can order the correct voltage for your located country!

The amount of electricity our chiller uses is dependent on the external temperature, the set point of the water temperature, if it is placed in direct sunlight, and how often it is changed from cold to hot or vice versa. The unit is capable of being programmed to minimize the amount of time it is at the coldest (or hottest) temperature which saves significant energy consumption. In general, we expect costs to be less than $1 per day.

Not much really!

The chiller's 20 micron filter needs to be changed when discolored as shown on the maintenance sheet, which is approximately once per month. The external water strainer should also be checked at this time to be cleaned of any hairs, lint, or debris.

Besides that, when you switch the water approximately once a month, you should check for any visable dirt in the tub and give it a scrub with soap and water if needed.

Again, changing the tubs water depends on how many people are using the tub, and how often. For most users plunging 1-2x/day in a residential setting who keep up with their filter maintenance, the water can last for months at a time. We recommend draining, cleaning, and refilling the tub roughly once a month, or as needed.

The FujiTub is shipped in 2 boxes via UPS or FedEx Ground right to your door. One box contains the tub, and the other contains the chiller. If you just ordered the tub then you'll recieve 1 box. Please note that you must have someone present to sign for the chiller upon delivery.

The Chiller should always remain in its normal upright position (wheels underneath). If The chiller has been on its side or in any other position, it should be left upright for 12 hours before use. Ensure that all components are dry and drained before packing it away for transportation. If shipping the FujiTub, care should be taken to ensure that proper packaging is surrounding the chiller to absorb shocks or impacts. The tub itself is ver durable and fairly light so it's no problem to take anywhere. However flying with the chiller is possible but it's considered an overweight item and can be difficult to protect appropriately. We recommend the safer, cheaper option of shipping the chiller via FedEx or UPS if you desire to air travel with it. You can view our complete takedown and packaging process here.
