What is an Outdoor Sauna?
An outdoor sauna is a standalone structure placed outside your home, usually in a backyard or garden. It is designed using weather-resistant materials and includes insulated walls, a heater, sauna stones, benches, and ventilation.
It works by heating stones with a stove or heater, which then radiate heat into the air. Water can also be poured over the stones to create steam and increase humidity.
In simple terms, when asking what is an outdoor sauna, it is a private outdoor heat therapy space designed for relaxation, sweating, and wellness benefits in a natural environment.

Outdoor saunas offer several lifestyle and wellness advantages:
1. Natural Connection

Types of Outdoor Saunas

6. Electric Sauna
Electric saunas use heaters for fast and convenient heating. They are easy to control and widely used in residential setups.
How Outdoor Saunas Work
Outdoor saunas heat sauna stones using a heater. The process works as follows:
