    Bought mine 10 months ago. Took a bit to get to know how to maintain my tub, but I've got the routine down now. I've looked at other tubs, but love how small this is, perfect size for me (I'm 5'10"). Customer service is very helpful and responsive. Since I live in hot Arizona, I use this every single night, right after I take a shower, so as to keep the tub clean. Too many benefits to list out, very happy with this purchase, highly recommend it!

    Cycling , Psoriatic Arthritis and Ice baths

    I am an avid Gravel cyclist trying to maintain between 120 and 160 Miles per week. I am currently being treated for Psoriatic Arthritis for the past 2 years, and it has had its ups and downs. My main challenge is inflammation setting in after every ride. For the past 2 months, after consulting with my Dr., we decided to add and monitor ice bath options. I started with the research and initially pegged a standalone tub, filling it with Ice, which, as you can imagine, becomes expensive and requires a lot of maintenance. I invested in Inergize Health and their Cold Plunge unit. Within the first week of 5 mins @ 50 degree F sessions after each ride. I could consistently reach my mileage goal and increase my workload and intensity by maximizing my efforts and cadence. In the past 2 months, I have increased my fitness level to closer to what it was in 2022. Feel free to look me up on STRAVA and follow my progress towards getting my abilities back. I would also like to mention the support aspect and the Inergize team assisting me. Unfortunately, my unit's outer housing got a minor dent, and at first, since there was no internal damage, I was happy to receive it as is. I will be honest. Eventually, it just bugged me, and I engaged the support team for some options. The unit was shipped, and the housing was replaced and shipped back. There was a total turnaround of 7 days, Ashburn, VA <=> California door to door. If I would make one suggestion, should you be considering 'plunging'…

    This thing is awesome!

    Super easy setup. Extraordinarily rare to have spare parts arrive with the order as standard for Inergize tubs. Very responsive support staff answer questions almost immediately.

    My family is addicted to this thing after one month.

    My sons and I use it almost every day. The benefits are evident from the start: more energy, better sleep, and mental health support.

    Thanks Inergize and team!

    Well made portable cold 🥶 plunge

    I love the size and portability of the Inergize. I’ve had it just over a month now and use it 4-6 times per week. It’s made a very positive impact to my elbow tendinitis and rotator cuff tear. Highly recommended!
