Archimedes Banya

During the summer of 1970, Moscow State University math student Mikhail Brodsky traveled to the Konda River in Western Siberia to log trees. While there, he visited his first banya—a public Russian bathhouse—and tried Siberian steam bathing. He became enamored of the practice, but didn't get to experience it again until visiting another Siberian town four years later. He soon started traveling throughout the world to study all the baths and hot springs he could find, earning the nickname Archimedes—for the ancient Greek mathematician—due to his habit of helping bathhouse staff members solve problems.

After moving to California, Mikhail decided to open his own bathhouse. Though design and construction took 12 years, he and a group of international friends finally opened Archimedes Banya, a coed public bathhouse that blends the aesthetics and traditions of Greek, Turkish, German, and Russian bathhouses with modern amenities. Spa staffers usher guests into steamy hardwood saunas and cold swimming pools on four themed floors, each decked out in warm cream-colored tiles or cool blue and silver accents. Deck chairs populate the rooftop patio, where visitors take in views of the bay and excise any remaining stress by screaming at boats. In private spa rooms, therapists knead guests' muscles during Russian platza massages and soak them in natural herb and mineral baths. The bathhouse and its restaurant stay open as late as 12 a.m. on weekends.
