If you’re thinking about installing a sauna at home and can’t decide between a dry or wet sauna, here you’ll discover all the key differences. Both options provide relaxation and wellness, but they work differently and the overall experience can vary greatly. In this comparison guide, we explain everything you need to know so you can choose the one that best suits you… and your skin.
What Is a Dry Sauna (Finnish Sauna)?
A dry sauna, also known as a Finnish sauna, is a wooden cabin that uses dry heat, generating high temperatures (usually between 80 and 110°C) with very low humidity levels (around 10–20%). The heat is produced by electric heaters or stoves placed over volcanic stones.
It is ideal for people looking for an intense experience, rapid sweating, and deep effects on muscles and joints. There are compact indoor models as well as the increasingly popular outdoor Finnish sauna, perfect for gardens or terraces.
What Is a Wet Sauna (Steam Room / Hammam)?
A wet sauna, also called a steam room or hammam, is an enclosed space where water vapor is the main feature. Temperatures are usually maintained between 45 and 55°C, while humidity reaches 90–100%, creating a soft and enveloping sensation.
The heat feels less aggressive, making it ideal for those who prioritize respiratory comfort, skin hydration, or have sensitive skin. It is especially popular in spas and wellness centers, such as the famous Arabic hammams in Málaga.
