Recharge. Replenish. Renew.

In the quiet heart of winter, when everything slows and the body longs for warmth, you are invited into a warm water oasis…

For three days, we gather in Spring Grove, Illinois, in a 6-bedroom, 5.5-bath sanctuary perched on a tree-lined hilltop and thaw in a warm water pool surrounded by natural light and a garden of plants. Guided by over a decade of water wisdom, Anne Koller—yogi, artist, and somatic water healer—leads you through an experience designed for deep replenishment from the inside out.

Immerse yourself in the rejuvenating power of water with daily H2flOw™ restorative water sessions—blending buoyancy-assisted movement with mobility, strengthening, and deep stretching. Within the water, the body softens as circulation increases and muscles unwind. Tension melts away, joints ease, and the nervous system gently settles into a slower, more receptive rhythm—an embodied “ahhhh.” Movement becomes fluid and effortless, supporting lymphatic flow, release, and full-body restoration.

From hydration workshops and nutrient-rich meals to water wisdom experiences—including water dance, water massage, and a candlelit floating sound bath—each day unfolds in a gentle rhythm of replenishment. Float in and on the water, where movement awakens creativity, expression, and joy in the body, all held within a collective of water sisters reconnecting to self.

Whether you are a new mom, an overworked entrepreneur, or an elder in a season of recovery, you are welcomed and held here.

You’ll leave feeling rooted in harmony that flows far beyond the retreat, with a toolkit of actionable practices to take with you—so you can restore, regulate, and replenish anytime you need.

Come flow with us.

H2flOw™ Retreat Water Sister Testimonials

"I didn’t realize how disconnected I had become… until I stepped into the water. This retreat gave me something I didn’t even know I was missing: a way back to myself." - Courtney

"The retreat itself had a variety of optional workshops that fit every age group & interest. The focus on water & all that it provides in life was a beautiful theme. I came home with a healed & happy heart. H2flOw is powerful in the most gentle way. The women in this group made my experience a joyful one that I will forever cherish!" - Gayle

"I came to this retreat to celebrate and mark a new chapter in my life, and I can honestly say that this experience gave me exactly that. Especially through the closing ceremony and my private water session with Annie, I felt a sense of completion, of returning home to myself." - Thaime

"This retreat felt like a reclamation of self. Being surrounded by water created space for me to slow down, listen to my body, and reconnect with myself in a deeper way. What stood out most was the freedom to engage on my own terms. I could drop in fully, or take space when I needed it, and that autonomy made all the difference. I left feeling grounded, renewed, and more connected to myself than when I arrived." - Ali

"Attending H2FlOw was one of the most transformative experiences I’ve had in my life. From the moment I arrived, I could feel that I was stepping into something deeply intentional and sacred, something created with care, love, and true expertise. I left H2FlOw with more than just memories. I left with tools, a renewed sense of strength, and a deeper connection to myself." - Megan
