Lawrence Azerrad, the designer of the Californication album art, shared a post on instagram regarding the project:
Twenty years ago, I had the pleasure of designing the album art for Californication with @chilipeppers. It feels like yesterday. Collaborating with Anthony Kiedis, Flea, and John Frusciante on this was definitely special, inspiring, exciting. Sonia Koskoff took the photo of that pool, which belonged to the parents of my childhood pals. 15 million+ copies and two decades later, it’s still fulfilling to see the album and the artwork out there. Thank you RHCP, and their fans.
