2026 Brings Major Membership Upgrades
Enjoy massive improvements to our award-winning Membership Key offerings beginning January 1, 2026!
Guided by all of your valuable feedback, we’ve simplified our offerings, identified the perks that matter most to you, and made them more attainable.
For starters, there are two tiers of general memberships. To put it simply…
Our Essential Wellness Key, is staying exactly as it was in 2025, including the price of $179 per month.
The second tier, our reimagined Serenity Key, offers you (among other things) 15% off ALL services. That perk is something that, as of 2025, was only available as part of our $360 per month membership. As of January 1, 2026, you can now get that same perk for ONLY $199 per month.
If you currently have the Essential Wellness Key and want to upgrade, let our concierge team know when it’s time to renew, and enjoy 15% off all services, 3 additional complimentary Halotherapy sessions per month, + more!
We’ve also reimagined two Specialty Membership Keys.
The Recovery Key, which is the perfect fit for athletes or those with an active lifestyle, now features 3 additional Halotherapy sessions per month, 1 additional Cold Plunge session per month AND a brand new perk that gives you 25% OFF all subsequent cold plunge, Halotherapy, or aromatherapy steam sessions per month! With all that added value, the price is staying the same at $195 per month.
Our second Specialty Key, the Oasis Key, is our ultimate amenities pass. With a new lower price of $299 per month, enjoy unlimited access to our amenities ANY DAY Tuesday-Sun, not just on days you book a service. In addition to a lower price, we’ve increased the number of complimentary Halotherapy sessions per month. And don’t forget, this is the only membership key that gives your guests a 10% discount for select services.
These improvements will go into effect as of January 1, 2026, not just for new members, but for existing members as well!
