Place the Cold Plunge System in a suitable location, ideally outside on the balcony, garden or terrace to take advantage of the overnight cooling effect.

Setting up the Cold Plunge is simple. It comes with a detailed instruction manual and we send a video by email detailing the step by step process.

From September to May in northern europe, adding ice will usually not be required as the temperature of the water will be cold enough for an effective Cold Therapy session. Of course it may be your preference to add ice to make it colder.

During the summer months it may be necessary during warmer days to support your sessions with ice.

Place the TrueCold™ Plunge System in a suitable location, e.g. the garden, terrace, or your bathroom, where it can be easily filled and emptied.

If possible, we recommend deploying it outside in the shade to maximize the cooling effect overnight, and then adding ice or ice blocks as needed.

Use a hose or bucket to fill the tub with cold water. The colder the water source the better. After filling the tub you can make it colder by adding ice cubes or warmer by adding warm water.

Ice baths, a form of cold water therapy, are widely used for their potential to boost energy, reduce inflammation, and support muscle recovery.

Athletes often use ice baths to help relieve soreness after intense workouts. Some people also use them to manage arthritis symptoms, improve mental well-being and stengthen their immune system.

Experts recommend a temperature between 5°C and 15°C and a duration of 2 to 10 minutes depending on experience and tolerance levels.

For most people, 2-5 minutes at a temperature of 10-15°C are enough to send a strong message to the nervous system and trigger a beneficial hormonal response.

Note: Always consult a healthcare provider to ensure cold water therapy is safe and suitable for you.

Yes, the Koanna® TrueCold™ All Weather Lid will protect your ice bath water from dirty rainwater, leaves, and insects.

Always keep the lid on when not using to keep out dirt. Change the water once a week without any additives. After emptying the water, wash inside with warm, soapy water to keep it clean longer.

To make your water last longer, try using bromine tablets or powder. Bromine is gentler on the skin and lasts longer than chlorine, especially in cold water. A small amount is enough to keep your water fresh for up to a month.

Always consult your doctor before using the Koanna® TrueCold™ Plunge System if you have any health issues!

Do not use if you are pregnant, under 16 years old or have a history of cardiovascular diseases.
