The original Hana sits on Westmoreland Street West in Grey Lynn, a wellness sanctuary where a full-spectrum infrared sauna at about 70C is paired with an ice bath around 6C in a private contrast room. Sessions run 60 minutes and the room takes up to two people, with a friend charged $40. Sans Ceuticals body products are laid out to use, and the front of house doubles as a shop for health and beauty labels.
