FAQ

Elahni is New York’s first wellness speakeasy, offering a hospitality-based contrast therapy experience in a cozy, intimate setting. By reservation only.

Yes. Elahni pairs a traditional Finnish sauna with cold immersion. We call the practice Temperature Contrast and serve it through an intimate, hospitality-led session.

Temperature Contrast is Elahni's practice of moving between sauna heat and cold immersion. The Signature follows a hosted rhythm; The Reset leaves the rhythm to you.

Traditional Finnish, or dry sauna. The sauna runs around 180°F, which is about 40 degrees warmer than infrared. The two have opposite ways of heating the body: a dry sauna heats the air around you, and that hot air heats you from the skin inward, while infrared leaves the air cool and uses light waves to warm your body directly.

The Signature is hosted from door to door. The Reset is self-guided: the room and its rhythm are yours, with the team nearby if you need anything.

The Signature moves through alternating rounds of sauna and cold immersion, paced by your host, then closes at the tea and tonic bar. The Reset is a shorter, self-guided session to use in the way that suits you.

Most guests leave quieter than they arrived; our guarantee says as much. For the physiology behind heat, cold, and the nervous system, the Elahniverse is open.

The room stays intentionally intimate. Current capacity and the choice between a shared session and the private room appear with each option on the reservations menu.

Arrive about ten minutes early so you can change and settle in. Doors close ten minutes after a session begins to protect the experience for everyone in the room, so we cannot guarantee entry after that.

No. Most of our guests are first-timers. During a hosted session, your host offers pacing and breathing guidance; you always control how long you stay in the heat or cold.

Bring a swimsuit and a water bottle. Towels, lockers, showers, and hairdryers are provided.

Please bring swimwear for your session. Please don't wear gym clothes or athleisure in the plunge. Swimwear keeps the water clean for everyone.

Yes — locker rooms with showers, towels, and hairdryers.

Length varies by session and is shown on the reservations menu. Leave a little time afterward to change and have a drink at the tea and tonic bar.

Yes. Choose the room on the reservations menu for a private session, or write to team@elahni.com for a larger occasion.

Temperature contrast involves extreme heat and cold. If you have cardiovascular or respiratory concerns, are pregnant, or have other relevant medical history, consult your healthcare provider before reserving and tell our team about anything we should know.

Yes. All guests must be at least 18 years old.

No. Every session is reserved in advance. If you are looking for a same-day opening, text the concierge line.

Each session has its own notice window, shown with your reservation details. Cancel before the deadline and eligible value is returned: session credits go back to their balance, while card-paid reservations can return as Elahni credit or to the original card. Inside the notice window, you may cancel, but the payment or credit is not returned, and self-service rescheduling is unavailable.

Elahni is a wellness speakeasy built around intimate sessions and considered hospitality rather than a free-flow bathhouse floor. The Signature is hosted; The Reset is self-guided; both are by reservation only.

12 W 27th Street, Floor 2, in NoMad, Manhattan. The entrance is intentionally discreet, and exact arrival details are included with your reservation.
