6 Outdoor Sauna Designs That Redefine Relaxation

In the pursuit of ultimate relaxation and rejuvenation, modern design has given traditional outdoor saunas a glamorous facelift, turning it into a showstopper of modern living spaces. Today’s savvy outdoor sauna designs are a perfect cocktail of aesthetics, cutting-edge technology, and functionality, and range from nifty, modular units that sneak into snug corners to opulent, custom setups that steal the spotlight; avant-garde creations are rewriting the rules on how we unwind with this age-old tradition. 


But how did this unique tradition begin?


The Origins of Sauna Culture

The sauna has a rich history that dates back thousands of years, predominantly rooted in Northern Europe, particularly in Finland. Originally, these were simple pits dug into a slope in the earth, which later evolved into wooden huts heated by stones. Over the centuries, the sauna evolved into a crucial cultural institution in Finnish society, embodying a communal spirit of relaxation, wellness, and social equality, and has now spread globally.


Did you know that Finland, a nation with a population of just over 5.5 million, is home to more than 2 million saunas? This staggering statistic reveals a sauna for nearly every two people, underscoring how deeply this tradition is woven into the fabric of Finnish life. Finland has even been coined the happiest nation in the world.

Could their sauna tradition be the key to a happy life? 


Health Benefits of Sauna Use 

Regular sauna sessions have been associated with numerous health benefits, including improved cardiovascular health, reduced stress levels, and enhanced detoxification processes. A study on the effects of sauna use on depression found that using a sauna leads to a significant boost in endorphins, which appear to play a role in the euphoric feeling often experienced after exercising. Moreover, the ritual of transitioning from the intense heat of a sauna to the refreshing chill of outdoor air is believed to boost immune function and enhance resilience to stress. 


Having explored the myriad health benefits that saunas offer, let’s delve into the different types of saunas available today, each designed to cater to specific preferences and wellness needs.


Types of Saunas 


  • The Finnish Sauna: A staple of traditional sauna culture, this wood-lined room is heated to temperatures between 70°C and 100°C (158°F and 212°F). A stove topped with volcanic rocks heats the air, and users enhance the experience by pouring water on the rocks to create steam. Celebrated for its dry heat, the Finnish sauna promotes intense sweating and aids in detoxification.
  • Steam Saunas: Also known as steam rooms, these operate at lower temperatures of about 40°C to 55°C (104°F to 131°F) but maintain nearly 100% humidity due to constant steam. The moist heat is beneficial for respiratory and skin health.
  • Infrared Saunas: These use infrared lamps to heat the body directly, rather than warming the air. Operating at cooler temperatures between 45°C and 60°C (113°F to 140°F), infrared saunas are suitable for those who find traditional sauna heat too intense.


Understanding Outdoor Sauna Construction 

Once you’ve decided on the type of sauna that aligns with your wellness needs, the next step is to consider the construction aspects that will ensure your sauna is a perfect fit for your outdoor space. Here are some essential features to evaluate when selecting the right sauna design for your home:


  • Material Quality: Opt for saunas made from durable, weather-resistant woods like cedar, hemlock, or spruce, which stand up to rot, mold, and mildew.
  • Insulation and Heating: Good insulation is vital for energy efficiency and maintaining the desired temperature. Examine the insulation type and the quality of the sauna’s heater—options include electric heaters, wood-burning stoves, and infrared heaters.
  • Size and Capacity: Consider the typical number of users. Outdoor saunas range from compact 2-person models to larger units accommodating 6 or more, ensuring everyone has comfortable seating.


Armed with the essentials, let’s discover how contemporary sauna designs can enhance your outdoor environment.
