Cold plunging is one of the fastest-growing recovery practices in wellness and sports. But not all cold plunges are created equal. Many rely on harsh chemicals or inferior cleaning systems that can irritate skin and require constant maintenance. That’s where a salt water cold plunge stands out - especially when powered by Coldtub Pal- Coldtub’s fully automated Dead Sea salt sanitation technology.

Key Summary

A salt water cold plunge offers the same recovery benefits as traditional cold plunges while keeping the water naturally cleaner, softer, and healthier. Every ColdTub uses a proprietary Dead Sea salt system that minimizes chemical use, reduces upkeep, and delivers a smoother recovery experience - all with temperature control ranging from 35°F to 104°F.

Why Choose a Salt Water Cold Plunge?

Traditional cold plunges often use chlorine or bromine to keep the water clean. While effective, those chemicals can dry out your skin and leave an unpleasant smell. Salt water plunges, on the other hand, use natural minerals to sanitize the water safely and effectively - offering a cleaner, more refreshing soak. Others also use Ozone systems and claim “No chemicals” are needed but Ozone is an oxidizer not a sanitizer. This may work for a low-use residential application but not in a high use commercial application. Our systems utilize an Ozone system as well but in pair with Coldtub Pal to create a full loop sanitizing and oxidizing system.

Due to our sanitation system working off of a probe which reads the water chemistry every 2 minutes, our Dead Sea salt system uses only 1/10th of the sanitizer needed to keep the water sanitized that standard systems use. The result? Crystal-clear water that’s softer on your skin and easier to maintain. No harsh smells, no chemical film, and no constant testing required - making it ideal for at-home and commercial use cold tubs.

How Salt Water Enhances the Cold Plunge Experience

Beyond sanitation, minerals like magnesium in our Dead Sea salt can ease muscle aches, decrease inflammation, reduce stress, improve blood flow,and improve sleep quality. Combined with the physiological effects of cold exposure - like increased dopamine releases and the reduction of lactic acid - you get the best of both worlds: clean water and deep recovery.

Plus, every Coldtub doubles as a hot tub. With temperature controls from 35°F to 104°F, you can choose cold therapy for recovery one day and warm soaking for relaxation the next - all managed through our custom Coldtub app.

Low Maintenance, High Performance

When it comes to upkeep, salt water systems win every time. Coldtub’s automated sanitation and filtration system checks water chemistry every two minutes and adjusts itself automatically. That means less manual work, fewer chemicals, and more time to focus on recovery. Whether you’re a home user or a commercial facility, this makes your salt water cold plunge nearly self-maintaining. We also have a one-of-it’s kind 1 micron antimicrobial filtration system. Filtering down to 1 micron which filters 20x-50x smaller of a particle than most filters on the market.
