FAQ

Can I use it indoors and outdoors?

Yes - it's built for both indoor and outdoor environments. Its weather-resistant exterior, insulated rain cover, and durable construction are designed to perform year-round in any climate, while still being perfectly suited for indoor wellness spaces. Nevertheless, we recommend placing the unit under some form of shelter to extend its lifespan and protect it from prolonged exposure to harsh weather.

Do you ship overseas?

Yes. We ship internationally. Delivery times vary depending on your country and customs clearance. You will receive shipping information once your unit ships.

Does it require professional installation?

No professional installation is required. Simply place it on a flat surface and connect it to your Borealis™ heater and chiller using the provided hoses. Once connected, fill it with water and set your desired temperature.

What if I didn't book a setup service?

If setup service is not booked, delivery is to the doorstep only.

Bringing the unit into position may require at least 2 people due to the weight and size, but the actual setup and installation are very simple — place the unit, connect the provided drainage valve, fill it, and plug it in.

Please note that setup services are not available in every country.

To check availability in your area, please contact support@tundra.health.

What power outlet do I need?

• Most markets (EU, SG, AU, UK): 220–240V

• North America & Japan: 100–127V

Your unit will be shipped with the correct voltage and plug type for your country.
Simply plug it into a normal household outlet – no special wiring required.

Note: To operate the LED light of the tub and the Borealis™ Heater & Chiller unit, you need 2 separate power sockets.

Should I keep the unit running all the time?

Yes, we recommend keeping it running.

Circulation, filtration, and sanitation are only active while the Borealis™ system is operating. Once the water reaches your set temperature, the system automatically switches into energy-saving mode and maintains the temperature with minimal power consumption.
