SaltMineArium, LLC, Bellevue

In the salt rooms at Salt Mine Arium, the atmosphere is cool and quiet and the walls glow. The two rooms are composed entirely of pink and white bricks made of Himalayan salt. The design creates an environment full of dry air saturated with negative ions, which can rejuvenate lungs, skin, and sinuses by cleansing them of pollens, pollutants, and toxins. Visitors relax on reclining chairs or practice yoga, enjoying stress-reducing sensory input such as wave sound from live speakers, the gentle splashing of water, and light effects. The rooms also feature a briny fountain and a halo generator that infuse the air with salt dust to further cleanse lungs and breathing passages.

Although the public salt caves are the main attraction, the healing powers of salt come through in the center's other popular services. They offer different types of massage, including ashiatsu massage inside the salt rooms. Guests can also choose from a wide selection of Himalayan salt products and lamps.
