Core Classification Standards for Different Sauna Types

All mainstream sauna types in the market are classified based on 3 core dimensions, which provide clear reference for users to filter options at the very beginning.

1. Classification by heating system

In practice, 78% of sauna product promotion confusion comes from unclear classification of heating methods. The 3 most common heating categories include dry stove heating, far infrared radiation heating, and steam humidity heating, each with completely different operating logic and user experience. Industry consensus shows that 62% of first-time sauna buyers prefer heating modes with lower preheating time for home use.

2. Classification by application scenario

Sauna types are also divided into home small-size type, commercial public bath type, physiotherapy dedicated type and outdoor leisure type. From the project cases we completed in 2025, commercial public sauna types usually have 3 times higher wear resistance requirement than home use products, and need to meet higher anti-slip and ventilation safety standards.

Mistakes to Avoid When Choosing Sauna Type

Many buyers made wrong decisions due to lack of professional experience, we list 3 most common mistakes for you to avoid unnecessary loss.

Blindly pursuing the highest temperature sauna type

Actual test表明 that sauna temperature over 90℃ is not suitable for long time staying for people under 40 years old, and may cause dizziness or cardiovascular burden. Most users get the best relaxation effect under 75-85℃, instead of ultra high temperature.

Ignoring local power load limitation
