Chest freezer to cold plunge kit
Upon purchasing, you'll get access to our detailed instructional video. The video lasts about 25 minutes and includes everything you should do to make an awesome chest-freezer cold plunge.
For those who know, a chest-freezer VS an external chiller unit is a "no brainer". External chiller units are like the external A/C units of your house. Which means that are often loud, need a lot of energy to work and will condensate water (i.e. get your floor wet). In the other hand, a chest freezer cold plunge is quiet, does not condensate at all, will keep ice-cold water even at 120F outside and the best of all it's simple design makes it extremelly realiable & energy efficient. Seriously, a chest freezer cold plunge will consume less than $20 a month of energy while a 1HP external chiller may run for over $100 a month!!
- It really works like a dream. No difficultities at all, just watched the build video & followed along. My set-up is in my garage, and it is perfect! ~ Brandon Smith
- Super happy with my set-up. Instructions were super clear and the build looks good and durable. The filter is powerful and the safety system self-disconnect works great; also the liner fits perfectly. Thank you BoxPlunge! ~ Steven Ferguson
- I got a Box Plunge DIY because of the ease of it. It went together quickly. If the freezer ever goes bad and can’t be repaired, I can swap the kit over to a new freezer and I’m not out the total cost of a built plunge. If for some reason I decide cold plunge therapy isn’t for me, I still have a working chest freezer. This kit is really a “set it and forget it” deal. I clean the skimmer and filter, and use H2o2 and my water is crystal clear over 3 months later. I highly recommend Box Plunge! ~ Jason Montaño
-After plunging at a local shop I wanted one for the house for convenience and economic reasons. Sourcing and neatly combining all the components for an optimal home plunge was a bit daunting so I started looking for kits. BoxPlunge had everything I needed and made it easy. This was key as I didn't have a lot of spare time to figure it out on my own. And frankly, while I could have spent the time to do so, I don't think it would look nearly as sharp. This was about as plug and play as it could get. My wife and I are now in there daily. It’s great that we have an activity to do together before the kids are demanding our attention, and I’ve got way more energy and focus for the first half of the day. So glad I’m back plunging. ~ Stephen christy
I wanted to find a way to put a cold plunge indoors without worrying about the noise or water leaks of a cooler unit. Boxplunge’s setup just works. The price is great, the system is easy to use, and the directions are super simple. ~ Matt Marcus
Love my cold plunge setup from BoxPlunge. I got it for reducing inflammation and improving mental health. It was easy to setup and cost effective. The whole setup is very quiet. ~ James Cogliette
After extensive research. This product, in my opinion, provided the best value on the market. The instructions to set up the BoxPlunge were clear and easy to follow. Only a few days into ownership and so far I am very satisfied with the product and the service I’ve received from BoxPlunge.com. ~ Sherin B.
The BoxPlunge Company Kit for a medium freezer offers an excellent and affordable entry into the world of cold plunging. Assembly was surprisingly straightforward, and all components functioned perfectly upon setup. The only minor hiccup encountered was aligning the magnet with the Cold Plunge Sanitation box, an area where the instructions could provide more precise guidance. However, this small detail aside, the rest of the process was simple and seamless. The convenience of having a cold plunge readily available has been a game-changer for the entire family. Our varsity athlete son, in particular, has found immense relief and a noticeable boost in recovery after practices, consistently putting a smile on his face. Considering its price point and overall quality, this kit is an unbeatable value for anyone looking to incorporate cold therapy into a routine. ~ Benjamin K
I bought the control box and filtration system, and I’m so happy with my purchase. The control box makes keeping all of the wiring so tidy, and it was incredibly easy to set up with how plug-n-play everything was. Setup took maybe 10 mins total, everything is organized in a way that makes it super easy. I love that the pump and freezer turn off as soon as the lid lifts up, and all of the small touches like the wire protectors & wire sleeve make everything look so tidy. I’m a DIY guy and really considered piecing together all of these parts separately, but I’m so glad I decided to go with the BoxPlunge setup for how easy it was and how well it all works ~ Mark Garken
