The main difference between
Yenisey and Yukon and Lena tubs lies in the materials used to construct them.

Yenisey is made from cast stone, giving it a more traditional feel and appearance similar to a normal bathtub.

Yukon and Lena are constructed from DWF (double wall fabric), a lightweight yet sturdy material similar to what is used to make stand-up paddleboards.

Yes, TUNDRA is engineered for both indoor and outdoor use.

The Cooler & Heater - Borealis features an IPX4 rating, ensuring protection against splashing water from any direction.

However, we do recommend setting up the equipment in a sheltered area to minimize wear and tear and prolong its lifespan.

Yes, you can adjust temperature, set time schedules and switch on/off your TUNDRA Ice Bath with your smartphone.

TUNDRA comes with a strong cleaning system that includes ozone sanitation and a polypropylene filter (more information here). This can keep the water fresh for a couple of weeks or even months.

Changing water is very easy, just follow these simple steps:

1. Disconnect the water-in-hose (which is usually connected to the bath tub to fill in water)

2. Place the hose to any water drainage

3. Switch on the cooling/heating device

4. The water will now get sucked out of the tub and flow directly into the drainage

5. Once the water reaches the lowest level of the water-out-hose you can disconnect the hose and put it directly into the bath tub to really pump out all the leftover water

6. As soon as the tub is empty, re-connect the hoses

7. Fill in fresh water

BE AWARE to switch off the device once there's no water to pump anymore. The device shouldn't run with sucking air for too long.

We recommend changing the filter at least once a month to maintain clean water. This frequency may vary depending on the overall hygiene practices of those using the plunge.

The regular model takes approximately 4.2 hours and the pro version takes around 2 hours to cool and heat 200 liters of water from 23°C to 5°C and vice versa.
