A few years ago, Grace Guo began to crave places in New York City where hanging out with friends didn’t have to involve alcohol.

Newly sober and surrounded by friends who also chose not to drink, Guo said she wanted alternatives to the typical social scene. After some research, she landed on Bathhouse and Othership: social wellness clubs designed to create communities around improving health.

“Honestly, it kind of just feels like going to a spa together and spending an afternoon together. I think for me, it just feels much better rather than staying out late at night,” Guo told CNBC.

She’s one of a growing number of people seeking out membership clubs and other places that are structured around maintaining health while also acting as a spot to foster connection.

And those spaces are becoming booming businesses, too. Bathhouse, which opened in 2019 in Brooklyn, New York, told CNBC exclusively that it expects to hit around $120 million in revenue by the end of this year. It declined to disclose any of its other financials, as did Othership.
