Please check your local fire department rules and regulations with regard to portable outdoor fireplaces. In most states you can legally use Sweat Tent in the backyard of your single-family home. ONLY USE SWEAT TENT OUTDOORS at least 2 feet away from structures, brush, and low-hanging branches.

Yes! Our tents are constructed with two layers of durable fabric with one layer of insulation in-between that retains heat very well, even in colder climates. When used properly, Sweat Tent will maintain temperatures of 180°F+ in temperatures as low as 10°F.

Sweat Tent has a built-in skirt running along both the interior and exterior of the base. We recommend weighing down the skirt with heavy weights such as cinder blocks, bricks, or sandbags. It also comes with ground stakes and ropes to tie it down and secure it further in windier conditions.

No. Sweat Tent is made of Oxford 210D Nylon that is rated to 300°F, meaning it will not melt or leach chemicals at 200°F (the approximate highest temperature our saunas go). The tent windows are made of a high-temperature performance TPU.

We put our saunas through testing using the highest quality, USA NIST calibrated equipment on the market from Forensics Detectors. Our test results show that when Sweat Tent is heated to 200°F there are zero concentrations of CO or VOCs present in the air.

Yes, you can leave it up permanently. Sweat Tent is made from a durable, weather-resistant fabric and includes a weatherproof roof cover. However, we do recommend packing it up for storage inside during times of extreme weather.

It does not smell, and there is not much cleaning required. Moisture runs down the sides of the tent walls and drains onto the ground. Any residual moisture is evaporated due to the high heat inside the tent. We recommend emptying the ash tray and removing excess soot from the chimney after every 3-4 uses.

Sweat Tent measures 6ft (L) x 6ft (W) x 7ft (H). The tent skirt that runs along the exterior of the tent adds another 6 inches to the footprint on each side.

Ensure the rectangular air intake vent at the bottom of your tent is open to allow fresh air to continuously flow into the front of your stove. Also make sure the air control vent on the ash tray is in the fully open position. Light a fire in the stove using fire starter squares and 1-2 pieces of dry hardwood firewood (maximum 16 inches long - we recommend using 12 inch long pieces).

Close the stove door and latch it shut. Let the fire get going and run for about 15 minutes before opening the stove door and adding another 1-2 pieces of hardwood firewood. Close the stove door, latch it shut, and wait another 15 minutes. Now your Sweat Tent should be nice and hot (180°F-200°F). If it's not, pull the ash tray out slightly and/or add another piece of wood.

Your stove and chimney pipe may become red hot in use. Do not worry, you're not in danger. However, we do not recommend over-firing your stove like this very often, as it could damage the stove.

To reduce the likelihood of over-firing your stove, you will want to restrict airflow to the stove to slow the burn rate of your firewood, as well as use no more than 4 pieces of split wood at a time in the fire chamber.

• The Plunge uses the built-in refrigeration system of a chest freezer to cool the water.
• Unlike traditional systems that rely on external chillers (pumps, pipes, fans, heat exchangers), our unit is fully self-contained and cools through passive heat radiation inside insulated walls.
• Simpler. Quieter. More efficient.

• Unlike other cold plunge systems that rely on chillers to extract heat from the water via a heat exchanger and a fan,
  the Sweat Tent Premium Plunge passively radiates heat through the outer walls of the freezer, providing a simpler and more energy-efficient solution.

The unique design of
the Sweat Tent Premium Plunge offers several advantages over traditional chiller-based systems:

1. Quieter operation:
   The Sweat Tent Premium Plunge operates without the need for a fan, making its refrigeration system significantly quieter than systems using chillers.
2. Less maintenance: The simplicity of
   the Sweat Tent Premium Plunge's design translates to fewer moving parts and less complexity, resulting in low maintenance requirements compared to external chiller-based cold plunges which do require yearly maintenance and are much more likely to break down (less reliable at freezing temperatures).
3. Superior insulation:
   The Sweat Tent Premium Plunge features exceptional insulation capabilities, thanks to the thick foam layer between the inner and outer walls of the freezer (>3" of insulation). This advanced insulation ensures the water remains cold for extended periods, reducing the need for the compressor to run frequently. Also, the insulation guarantees "drip-free" walls which means there will not be any sort of external moisture due to condensation, in other words, a completely dry floor. Further, we guarantee water won't freeze even during the coldest of winters.
4. Uses less energy: The Sweat Tent Premium Plunge cooling system is simple ~ works like your home freezer, not like the other cold-plunge chiller systems. You see, when water moves through pipes, it can pick up heat, making the system work harder to cool it down again. But BoxPlunge doesn't have this problem because it doesn't have water pipes at all. So, it uses less energy to keep the water cold. It's like it's saving energy because it doesn't have to do extra work to cool down the water again (like every other cold plunge in the market that has an external chiller system).
5. Less heat dissipation: The heat radiated from a Sweat Tent Premium Plunge will not make the room hot (no exhaust required), any external chiller will make the room hotter, unless you install an exhaust.
6. No Plumbing: Not having an external chiller means water does not have to flow out of the unit to get chilled, this avoids any plumbing work which significantly reduces complexity on the system. Further, when there is external plumbing such as an external filter canister there will always be condesantion as a filter canister is less than 1/6" thick; this also means that if you were to turn off the chiller bacteria will grow incredibly fast inside that filter canister (room temp. water in a dirty filter canister is the perfect environment for bacteria or mold to thrive)
7. No Condensation: Unlike external chiller systems that need a water tray for managing water condesation (plumbing systems are never insulated enough for there to not be any condesation even the best chillers will need a water tray),
   the Sweat Tent Premium Plunge guarantees your floor will stay 100% dry with not tray needed.

• The Sweat Tent Premium Plunge freezers are equipped with a safety feature that automatically disconnects all electronics whenever you open the lid. You'll know it's working when you hear a "clicking" sound, which indicates the tub is safe and power-free. You will also be able to see the thermostat display turning OFF.
• Additionally, all the electronics are GFCI protected. Which means everything will disconnect in case there is any electrical fault (similar to the breakers of your home).
• In addition, all electronics are protected by a GFCI (Ground Fault Circuit Interrupter) system. This means that in the event of any electrical fault, power is instantly cut — similar to the breaker protection in your home.

Safety isn’t an add-on. It’s built into the core of the design.

• We are one of the only cold plunges in the market that are capable of producing ice. Simply drop the set temperature below 32F and let the ice form. But please understand that ice-formations may be abrasive.
  
  

• The water won't freeze unless you want it too. With more than 3" insulation, 1,200gph water pump and with the water always inside the tub (i.e. no plumbing at all), it will not turn into ice.
  
  

• The Sweat Tent Premium Plunge can be kept outside under shade and ideally protected from the rain. Keep in mind that by leaving it exposed to extremely hot conditions or heavy rain showers you may shorten it's life-span.
  
  A cover is highly recommended.
  
  

• To eliminate any risk of leaks, we permanently seal the original chest freezer drainage port. This prevents potential water escape through the factory rubber gasket and ensures long-term structural integrity.

• Instead, every Sweat Tent Premium Plunge unit includes a powerful sump pump and drainage hose, allowing you to fully empty the tub in less than 10 minutes.

• This is up too the customer, please leave an order note whether or not you want a hinged lid. If no note is made, we will automatically ship you your plunge with a hinged lid.

• Sweat Tents cold plunge pools are engineered with advanced performance and water-quality technology to deliver a superior cold therapy experience.

• Our plunge features a high-efficiency filtration system that includes a built-in skimmer and a 2.5" x 10" micron filter. This system produces over 1,000 gallons per hour of circulation, exceeding the flow rate of most cold plunges on the market.Each unit also comes equipped with an integrated ozone generator, which actively sanitizes the water and helps maintain a low-bacteria environment for extended periods. The result is cleaner water, reduced maintenance, and a more hygienic plunge experience.

• Together, these systems ensure consistent performance, crystal-clear water, and a powerful cold immersion experience designed to support recovery, resilience, and overall well-being.
