Elahni is a first of its kind Wellness Speakeasy®. As a private, immersive space designed for deep restoration, we blend the timeless practice of Temperature Contrast — through a traditional Finnish sauna and ice baths — with an adaptogenic tonic bar and a curated library, creating an atmosphere that invites both stillness and connection.

Is this contrast therapy?

We call what we do Temperature Contrast, a guided experience alternating Finnish sauna at 180°F and ice bath immersion at 39°F. While the practice shares roots with contrast therapy, our approach is different: every session is hosted and guided, limited to four guests, and designed around nervous system restoration rather than physical recovery alone. If you're searching for contrast therapy in NYC, this is what it looks like when the experience is built from first principles.

What is Temperature Contrast?

Temperature Contrast is Elahni's guided practice of alternating between extreme heat (Finnish sauna at approximately 180°F) and cold immersion (ice bath at 39°F) across three intentional rounds. Each session includes breathing guidance, aromatherapy, and adaptogenic beverages. The practice trains your nervous system to move between states of activation and recovery with greater ease, building resilience that extends beyond the session into daily life.

Is Elahni a self-guided experience?

No, Elahni is not a free-flow space. Our sessions are thoughtfully facilitated to create a structured and intentional journey. This ensures every guest experiences the full restorative benefits of our practices. As such, it is important each guest arrives at least 5, ideally 10, minutes early.

What does a typical session at Elahni include?

Each Temperature Contrast session blends aromatherapy-infused heat exposure, ice bath immersions, and moments of stillness. You'll also have access to our adaptogenic tonic bar and curated library, all within an intimate setting designed for reflection and renewal.

What are the benefits?

Temperature Contrast at Elahni supports nervous system regulation, improved sleep quality, more stable energy levels, faster physical recovery, and a calmer stress response. The alternation between heat and cold trains your autonomic nervous system to shift between activation and rest more efficiently. Over time, your capacity to stay composed through challenging experiences deepens.

How many people are in a session?

A maximum of four. This is intentional. Our intimate scale creates the conditions for psychological safety, authentic connection, and the kind of nervous system downregulation that large group settings cannot provide.

When should I arrive?

To honor the experience for everyone, our doors close 10 minutes after each session begins. Please plan to arrive a few minutes early to settle in. If you arrive later than this window, entry cannot be guaranteed.

Do I need prior experience with saunas or ice baths?

Not at all! Our guided sessions are designed for all experience levels. Our hosts will support you throughout, offering guidance and modifications to ensure your comfort and safety.

What should I bring to my session?

How is Elahni different from a bathhouse or spa?

Elahni is not a spa or bathhouse. We're a wellness studio focused on nervous system health through guided Temperature Contrast. Sessions are limited to four guests. Every session is actively guided by a host. The experience is designed around interoceptive awareness, training your ability to sense and regulate your internal state. We call ourselves a wellness speakeasy because the space is intimate, intentionally hidden, and designed for depth over volume.

Sauna in NYC, NoMad

A real Finnish sauna in NYC

Elahni is a guided Finnish sauna and ice bath in NoMad, Manhattan. Sessions run 70 minutes, hold four guests at most, and cost $65 per seat. The sauna is traditional and hot, around 180°F, paired with a cold plunge, and a host sets the pace as you move between them.

Reserve a session

What the session is

Most saunas in NYC are a bench tucked into the back of a gym or a single infrared cabin you sit in alone. Elahni is built around the sauna itself. You arrive, change, and step into a traditional Finnish sauna that runs hot the way it should. Over 70 minutes a host carries the structure, moving the small group between the heat of the sauna and the shock of the cold plunge.

The room holds four guests at most. That keeps it quiet and uncrowded, with no wait for a spot on the bench.

Where it is

Elahni is in NoMad at 12 W 27th Street, Floor 2, a few minutes from the Flatiron Building and Madison Square Park. If you have been searching for a sauna near you in midtown or downtown Manhattan, this is central to both.

Why guided, and why small

Heat and cold do more when someone holds the pace for you. The host guides you through each round and your breathing, so you are not watching a clock or second-guessing yourself. With four guests at most, the session stays calm and personal rather than turning into a busy bathhouse floor.
