WHY RENT FROM TUNDRA
Try it in your own space before you commit.
Everything included
Tub, Borealis chiller and heater, hoses, cover, filter cartridges, delivery, set-up and collection.
No plumbing
A 13A socket, a tap with a hose connection and a drain within reach. The chiller runs from 3 °C to 42 °C, so the same unit does cold plunges and warm soaks.
Rent, then decide
If you buy a TUNDRA system after renting, one month of rental is credited against the purchase.






Mainland Singapore. We contact you within one working day of your booking to agree the delivery date.
A TUNDRA tub and Borealis chiller at your home, delivered, installed and collected by our own team. Rent for a month to try cold plunging, for a training block, or for as long as you like.
What is included
- The tub of your choice: Lena barrel, Yukon Regular or Yukon Large, each for one person. Or the chiller alone if you already have a tub.
- Borealis chiller and heater, 3 °C to 42 °C, so the same unit runs cold plunges and warm soaks.
- Hoses, cover and a 20-micron filter cartridge, plus one replacement cartridge for every month of the rental.
- Delivery to the room of use, set-up, first fill, a handover on the controls, and collection when the rental ends.
What you need
- A standard 13A power socket.
- A tap with a hose connection to fill the tub, and a drain or safe discharge point for water changes.
- A level floor that can carry the filled tub. Weights and dimensions are in the technical guide of each tub.

QUESTIONS
Before you book
Which tub should I choose?
Lena is a square barrel, 90 by 90 cm and 75 cm high, 300 L, the smallest footprint, for sitting upright. Yukon Regular is 135 by 72 cm, 340 L, for lying back. Yukon Large is 154 by 82 cm, 460 L, for taller users. All are for one person. Filled weights: Lena 314 kg, Yukon Regular 353 kg, Yukon Large 478 kg.
How cold does it get, and how fast?
The Borealis chiller holds any set point between 3 °C and 42 °C. On a 300 to 340 L tub the Gen 5 Pro cools at roughly 5 to 7 °C per hour, so the first pull-down from tap temperature takes a few hours; after that the chiller holds the temperature around the clock.
What about hygiene?
The chiller runs continuous ozone sanitisation with a 20-micron filter cartridge. You change the water every one to two weeks and the cartridge monthly; we include one cartridge per month of rental.
Can I rent for a weekend or an event?
Yes, on request. Short rentals and event set-ups are quoted from the dates, the location and the equipment. WhatsApp us with your dates.
Do you rent outside Singapore?
In Bangkok, Hong Kong, Manila and Jakarta through local partners, quoted per project.
