Enhance your sauna environment with the Round Aroma Stone, a versatile accessory designed to disperse your favorite scents. Measuring 1 3/4" x 1 7/8", this compact stone can be placed anywhere in your sauna, including within the heater's stones. Simply add a drop or two of your preferred essential oils or fragrances to enjoy a refreshing burst of aroma. Please exercise caution, as many pure aroma oils are flammable and may pose a fire risk if applied incorrectly.
