What is a shower steamer? Put them in the shower at neck or face level. If that isn’t an option place on the floor away from the drain. Water and steam activate the steamer and release its essential oils. Each oil has a different medicinal property. The handmade Summer Citrus is a perfect blend of refreshing & relaxing aromas with the comfort of citrus and lavender. Steamers last between 1-2 showers depending on the duration of your shower and where you place it.
