The culture of an auto body shop doesn't immediately bring to mind relaxation, but Onsen, a bathhouse in San Francisco, is reviving zen and the art of motorcycle maintenance. The shop, which has all the amenities and features of a traditional Japanese spa and bathhouse, is built in a former garage and auto body shop.
Though much of the wall space throughout Onsen is covered in Japanese art, the remnants of the auto body shop aren't difficult to spot. For instance, a wide open, airy room that holds the hot bath is made of exposed red brick -- part of the industrial history of the building.
In terms of amenities, Onsen has six treatment rooms which feature massage tables as well as the above mentioned communal bathing room.
