About this product
The Sweat Decks Rectangle Plunge - Premium Cold Water Therapy at Home
The Sweat Decks Rectangle Plunge is a purpose-built cold plunge tub designed for serious daily cold water immersion. Wrapped in aromatic red cedar with a medical-grade stainless steel interior, this plunge delivers precise temperature control from 35°F to 107°F through WiFi-enabled smart controls - set your ideal temperature from your phone before you even step outside. The integrated chiller, ozone generator, UV sanitation, and 20-micron cellulose filtration keep your water pristine for weeks without manual cleaning.
Regular cold plunging has been shown to reduce systemic inflammation, accelerate post-workout muscle recovery, improve cardiovascular health, and boost mental clarity through natural norepinephrine and endorphin release.

What our customers say
I love the Sauna and cold plunge I purchased from Sweat Decks. In addition to providing great products, their office is extremely helpful. My backyard is now a delightful retreat.
We had a great experience overall working with this team. They built and installed our sauna and also constructed a staircase leading up to it, and the final result exceeded expectations. I’ll note that things were a little bumpy right after purchase — the original person we worked with ended up leaving without notice, which caused some initial confusion. That said, the team handled it really well. Huge shoutout to Heath and Brandon for stepping in, taking ownership, and getting everything back on track. They were incredibly professional, thorough, and easy to work with throughout the rest of the process. From there, everything ran smoothly. The craftsmanship is excellent — the sauna looks beautiful, feels high quality, and the staircase ties everything together perfectly. You can tell a lot of care went into both the design and execution. They showed up when they said they would, communicated clearly, and kept everything clean and organized during the build. In the end, they absolutely delivered. Really happy with how everything turned out and would definitely recommend them.
I got a sauna and a plunge in the backyard from Sweatdecks. It was a one stop shop. After delivery, build, and execution they continue to be responsive for questions, and recommendations. Top shelf company. 5 stars! Many thanks, Heath.
Sweat Decks was incredible to work with! They built out my hot tub, sauna, and cold plunge and everything turned out amazing. The whole process was smooth, the team was professional, and they went above and beyond to make sure everything was perfect. What impressed me most is that the service didn’t stop once the build was done — they’ve been super responsive and helpful with any follow-up. Couldn’t recommend them more! ⭐⭐⭐⭐⭐
We went with Sweat Decks for our sauna installation and couldn’t be happier with the decision. They started with a site visit to figure out the best placement. We prioritized views and access to power and water and fortunately the best spot was also the least expensive for the build. There was a rough work visit from the electrician a few days before install, where he met with the courier to secure delivery of the sauna and heater. Then the guys came out and installed it in one day that weekend. For the longest, I had in my mind this idea that I could just DIY this project (and I could!), but why do that when you’ve got some experts who can get the job done right the first time! After getting the sauna my sleep stats are improved and my resting heart rate is down significantly. As parents, I believe this was one of the best investments we could’ve made! If you’re looking at Sweat Decks for the work, my guess is you’re already sold on their quality based on the reviews, but you’re not sure about the cost. That’s where we were for a while before just pulling the trigger. My only regret is waiting so long to get this sauna!
We love our sauna and cold plunge! We have used them without fail everyday since they have been installed. Working with Brandon has been super easy, he is very responsive and happy to answer any questions along the way.\ I’ve owned other saunas and a different cold plunge that required manual chilling. The difference is undeniable. The sweat decks products are superior and 100 times easier to use on a daily basis. The whole family loves them both.
