We've broken ground! The teller stations and offices are now gone, the old vault has been cleared out, and the shells of our pools are nearly complete.
Seeing the pools take shape has made the vision for Grotto feel a whole lot more real.
We're excited to partner with local Sillin Studios to continue refining the interiors, and we can’t wait to share more of the design soon.
Little by little, Grotto is becoming a place to soak, sauna, unwind, and connect in the heart of Fairfax.
Thanks to everyone who’s been following along and cheering us on. We’re so excited to bring this place to life.

It’s go time! Construction starts next week.
After months of design, engineering, permitting, and countless revisions with the various jurisdictions, we’re finally breaking ground on Grotto.
Fairfax locals: Beginning Monday, July 20, a portion of the former Bank of America parking lot will be closed for construction staging. Keep an eye out for signage as to which parking spaces will remain open.
We are beyond thrilled to begin work to bring this bathhouse to town. Along the way, we’ll be sharing progress and beginning many conversations about how the space will feel, refining our offerings, and shaping the experience with our community.
Thank you for following along—we can’t wait to welcome you in!

February is our last push to get Grotto funded and into construction and we’re looking for a few more private investors to step into key roles as we bring this to life.
If you’re interested in investing at a higher level, check out the details on our website or DM us. We’d love to connect!
For the broader community, our WeFunder campaign is live and open to anyone who wants to invest and support the project.
And if you’re not ready to invest but still want to help make this happen, we’re running a screaming deal this month on a one-year membership — deeply discounted and directly supporting the build.
Visit our website to invest or get involved.
DM us with questions.
Let’s make this happen.
