Williamsburg Salt Spa has imported over 15 tons of therapeutic salt from Poland and the Himalayas in order to create a unique microclimate rich in minerals, such as sodium, potassium, calcium, magnesium, iron, bromine, and iodine. During your 45 minute therapeutic session you will improve your health by relaxing in comfortable recliners, listening to the soothing sounds of music and breathing air that is saturated with these beneficial minerals. To create the Salt Cave, apart from salt, we used only natural hypoallergenic materials: wood, plaster, natural resin, and organic glues.
