Antoinette Marie Johnson has spent the better part of two decades shaping iconic restaurants, boutique hotels and cultural destinations. Now, she’s channeling that expertise into a wellness sanctuary she calls Grotto Baths—a members-only social bathhouse slated to open in Miami’s Wynwood neighborhood in early 2026.

“I saw a need for deeper human connection,” Johnson said. “Not through productivity, not through another business meeting, not through a typical social scene—but through meaningful rest, ritual, and gathering.”

Grotto will blend ancient bathing rituals with modern design, programming and community. Thermal circuits, mineral pools, cold plunges, ceremonial saunas and herbal steam rooms will be paired with a curated calendar of workshops in breathwork, sound healing, and somatic movement. The space will also feature an alcohol-free café with an organic menu designed by Tender Greens founder Chef Erik Oberholtzer, offering nourishing options for guests looking to linger.

“I wanted to create a space that allows for presence,” Johnson said. “A place that supports slowing down, feeling something in your body, reconnecting to yourself, and softening. That’s what Grotto is designed to do.”

softening. That’s what Grotto is designed to do.” The concept, which she co-created with real estate partner Nathan Kaplan, has been quietly in development for over two years. Johnson, who has a background in hospitality branding and previously worked with visionaries like Tony Goldman and Keith McNally, is intimately familiar with the cultural pulse of Wynwood. Launching Grotto there, she said, feels like a full-circle moment.
