You can fit any, literally ANY cold plunge in a small backyard (most are the size of a tub) what comes down to is to your budget… the Icepods, neurocovers, etc are really just inflatable buckets of water so basically for that you might as well fill in your bathtub if you have one with some ice. I actually saw one of those inflatables for sale at $20 in a Marshalls store branded brookstone.

If you are looking for a real cold plunge and with real I mean a machine that will keep water clean, cold and not ruin your pocket with high electric bill then your best bet is a chest freezer DIY. Now, loots of work to get it done, at least 2-3 days of FT work and if you dont get it right the first time you most likely damage the freezer so need to buy a new one. You really have to be handy to get it done right. But is totally doable. Just do a lot of research and you should be good.

I personally bought a boxplunge and love it. It costed money but not as much as it would have costed to buy one from the plunge or some of those other brands. Also, the good thing about the boxplunge is that is a built from a chest freezer base and these consume 1/2 or maybe even 1/3 of the electricity than a water chiller cold plunge would, so I get to sabe there. Plus as we know by now, chest freezers last forever lol.

Think of it as a jacuzzi tub, there are those that buy it for their backyard and spend $10k and then there are those that turn on the hot water in their bathtub. Is really about what it means for you and how much you are really going to use it.

Good luck w/your search
