Metal Grille Only (4'' x 10'') is a high-performance ventilation component designed to facilitate superior air exchange and temperature regulation within your sauna. This heavy-duty metal fixture is engineered to endure the intense thermal cycles and humidity of a traditional sauna environment, offering a durable alternative to standard wood covers. By allowing for a consistent flow of oxygen-rich air, this grille helps prevent heat stratification and ensures a more invigorating, breathable atmosphere for every session. The 4-inch by 10-inch dimensions allow for a precise fit into standard ventilation openings, making it an ideal choice for both custom builds and structural upgrades. Whether positioned as a low-level intake vent to feed the heater or as an upper exhaust to manage moisture, this functional hardware ensures reliable airflow without warping or degradation. This professional-grade metal grille provides a clean, modern aesthetic that integrates seamlessly into any wellness space, delivering a practical and long-lasting solution for maintaining optimal air circulation and user comfort in your home spa sanctuary.
