The foursome, who rose to fame as Los Angeles County lifeguards in the '90s series, will co-star in Back to the Bay, a docu-comedy about the actress' new careers.
The series will chronicle Eggert's efforts as she works on exercise DVDs and raises her 12-year-old daughter, while Bingham is setting up her own dating service.
Nolin will also be followed as she promotes her a book about postpartum depression, having just given birth to her third child, while D'Errico is said to be "a conspiracy theorist" whose goal is to climb Turkey's Mount Ararat and search for Noah's Ark.
Executive producer Scott Stone tells trade paper Daily Variety, "These amazing women have all embraced the nostalgia of the 'Baywatch' phenomenon and are ready to show us all how to have a blast again."
An air date for Back to the Bay has yet to be set.
