FAQs
Answers to the questions we are asked most often about TUNDRA cold plunges, chillers and saunas. We deliver worldwide from Singapore, with delivery included in the price. For anything not covered here, WhatsApp +65 8950 1028 or email info@tundra.health.
Choosing
How cold and how hot does it get?
The Borealis Gen 5 cools to 3°C and heats to 42°C, so one system covers ice-cold plunges and warm soaks. It holds your set temperature around the clock.
Can you build it into my home, hotel or studio?
Yes. We design and build custom plunges and saunas into residences, hotels and studios across Singapore, Hong Kong, Bangkok, Manila and Jakarta, from a single built-in plunge to a full recovery suite. Chat with us to plan your build or request a custom quote.
Can I use an infrared sauna outdoors?
The Equinox FS is designed strictly for indoor use (living rooms, gyms, bathrooms or covered dry areas). The natural Canadian Hemlock exterior is not treated to withstand rain, direct sunlight or high moisture. For a garden, patio or deck, choose a model built for outdoor placement.
Can I spread the payment?
Flexible payment options are available on most systems. Message us on WhatsApp and we will find an arrangement that fits.
Delivery and installation
Do you deliver to my country?
Yes. We deliver worldwide from Singapore: across Asia Pacific and the Middle East, Europe and the UK, the United States and Canada, and the rest of the world. Choose your country at the top of the page and you see prices in your currency, with delivery already included.
Is delivery included?
Yes, on all plunges, chillers, saunas and recovery devices, in every country we ship to. The price you see includes delivery to your door. In mainland Singapore, installation and commissioning are included too on standard products. We ship duties paid (DDP) wherever our freight partners can, and confirm any import charges with you in writing before your order ships. Filters and small accessories ship by air express at the rate shown at checkout. See the delivery and installation terms.
How long does delivery take?
Singapore: 1 to 2 days. Hong Kong, Asia Pacific and the Middle East: 14 to 18 days. Europe and the UK: 30 to 40 days by sea. United States and Canada: 30 to 45 days by sea. Rest of the world: 30 to 50 days. Flux and TUNDRAGUN go by air express in 5 to 10 days. Air freight for larger systems is available on request at an additional cost. We book the freight and prepare the export paperwork, and our team confirms your delivery window once the unit clears customs. See shipping and delivery.
Do I need special plumbing or wiring?
No. Every TUNDRA plunge and chiller runs on a standard 220 to 240V grounded household socket, with no electrician needed. You fill it with a normal hose, and there is no fixed plumbing. In Singapore we deliver, install and commission it for you anyway, and we arrange installation in our other markets on request.
Two exceptions. An Oasis running two Borealis Elite units needs two grounded sockets on two separate circuits, one per unit; if your site has only one circuit near the tub, an electrician can add a second before installation day. And a traditional sauna heater, such as the 6 kW Harvia heater in the Haven, must be wired by a qualified electrician.
Does a plunge need professional installation?
No specialist installation is required. The unit arrives fully integrated. Place it on a flat surface, plug it into a standard outlet, connect the provided drainage valve, fill with water and set your temperature. Never switch on before the tub is filled.
Running costs and water care
How does the water stay clean?
Water runs continuously through the system's filtration, and cartridge changes take about a minute. At handover we walk you through the simple care routine, and our local team offers servicing if you would rather not think about it at all.
How often do I change the filter and the water?
Clean the skimmer basket weekly to remove leaves, hair and debris. Replace the filter cartridge every 3 to 4 weeks depending on usage, and change the water every 3 to 4 weeks depending on hygiene and frequency of use. Add mild sanitizers (non-chlorine, non-bromine) to keep the water clean between changes. Replacement cartridges are on the support page.
Warranty and service
What happens if something breaks?
Your system is covered by our warranty, wherever you are. In Singapore our own technicians handle parts and labour on site, and in Hong Kong, Bangkok, Manila and Jakarta we arrange it locally. In every other country we send the replacement part free of charge and guide you through the fix by video call, or arrange a local technician. If a unit cannot be repaired, we arrange its return and send you a replacement. Warranty periods are listed on each product page and summarised on the support page.
