—The answer is: Absolutely! The answer to the question, "Do outdoor saunas need ventilation?" is a resounding "yes" from multiple perspectives: technical, safety, health, and comfort. Ventilation isn't optional; it's an essential, core component of outdoor sauna room design.

In a high temperature environment, the human body secretes a lot of sweat. Sweat contains not only water, but also chemical components such as sodium, chlorine, urea, ammonia, lactic acid, lipids, and cell metabolic waste. Therefore, taking a shower is a necessary step to completely remove sweat and harmful metabolic residues.

If the maintenance technical threshold and continuous labor intensity are used as the core evaluation criteria, the overall maintenance of the spa hot tub is more complicated; and from the perspective of structural stability and durability, the outdoor sauna room requires more protection and preventive maintenance.
