NAOSU is a Japanese and Chinese kanji that means “to heal” or “to fix”. We are a community sauna and cold plunge serving complimentary tea located in RiNo.

Swimwear or athletic clothing is required. We recommend bringing a towel and water bottle.

We have scheduled deep cleans every Tuesday where NAOSU will be closed. The sauna/cold plunge area is a barefoot space to maintain cleanliness.

We recommend cycling between heat and cold with 10-15 minutes in heat and 1-3 minutes in cold, 3 times to fill your hour session.

Stay hydrated and know your limits. If you start to feel unwell stop, seek a staff member for assistance.

All bathrooms and equipment are gender neutral.
