Courtney Wittich is the writer and cultural correspondent behind S.P.A. (Salus Per Aquam ~ Health Through Water), a newsletter dedicated to distilling all things wet pleasure for the post-iPhone leisure world.

Drawing on a career in fashion & lifestyle PR plus extensive event production, she examines the trends, rituals, and culture surrounding how we bathe — building online and offline spaces where sauna devotees, bathhouse operators, cold plunge converts, and anyone who's ever sunk into a hot tub after a long week can find common ground.

She hosts regular bathing club meetups in Los Angeles (sometimes New York and hopefully beyond), bringing together curious minds and seasoned soakers alike to experience the full spectrum of bathing culture firsthand.

At the end of the day, we all bathe. Whether your water is ocean, thermal spring, steam room, drinking mineral water, or your own tub with the door locked, S.P.A. is sure to have something for you.
