Testimonials

The crew at Kooru is phenomenal. Their plunge is an absolute game changer for me, I use it daily and it's made my life so much better. If you're a sauna user, this is a must have.
Jason H.
As a former professional athlete, I’ve been in a lot of ice baths and this is the best one I’ve experienced! I’m 6’9 and I can fully submerge my whole body (and head) under the water. It is so easy to maintain and it looks great in my house. Runs perfect with no issues. It is built to last and I’m so glad I got this instead of building my own. I’ll have this thing forever!
Adam
The cold plunge from Kooru has been nothing short of fantastic. It works incredibly well, looks great, and a no brainer for the price. The whole team at Kooru has been incredibly helpful and responsive. I use it 4-5 days and love it!
Doug S.
I couldn’t be more pleased with the cold tub from Kooru. Simple to operate, maintain, and it looks fantastic! You really can’t put a price on the convenience of having the tub available whenever you want.
Allen T.
This cold tub has been life-changing. After using this thing every day for about a year, I’m finding myself way less beat up after long runs and I’ve gotten a lot better mental focus throughout my day. Love the aesthetic of the wood that they did for these. It looks great on my back deck. Couldn’t be happier with it.

Yes, safety came first when designing this tub. If you have specific questions regarding safety, please email us @ kooru@breathedegrees.com

Yes! Your tub comes with an ozone filtration system and a 10″ filter to keep your tub clean. This tub was built to be low maintenance and have minimal water changes with proper upkeep.

Water temperature can go as low as 39º F. You can set the temperature to your preference at any temperature below 80º F. Please note the tub does not heat but keeps below the set point.

We recommend this tub for people 6’5″ and 250 lbs or less. XL tub can be made – please email us.
 
If you are looking to see how deep you can submerge yourself, try sitting on the ground and marking 28 inches on the wall. This will give you an idea of how high you can safely get the water up (the compartment is 30 inches tall). Most people find that this is more than enough to submerge their head if they wish.

Ozone or O3 technology is a common and safe water treatment system using pure oxygen. It is a powerful disinfecting agent and removes the need to use heavy chemicals. In short, ozone is terrific for cleaning water, which is why it is used with advanced drinking water treatment plants in the world.

Yes, our tubs are designed to be indoor or outdoor. If you live in a colder climate, it is important to leave the water circulating  24/7  if temps are below 32 for multiple days in a row to prevent freezing pipes. If it gets too cold for extended periods you may need to drain and empty the tub.
