The Piranhas ritual

Three movements,
one return to calm.

01温 · Warm

Heat & soak

Begin in the mineral onsen and private infrared sauna. Muscles soften, circulation opens, the mind slows.

02冷 · Cold

Plunge & awaken

Step into the ice bath. A bracing, deliberate cold that sharpens focus and floods the body with clarity.

03休 · Rest

Recover & restore

Close with massage, breathwork or stillness in the recovery garden. Let the nervous system settle.

By The Oberoi, Seminyak

7-metre heated jacuzzi

A seven-metre heated jacuzzi lined with natural stones — built for long, slow soaks.

The heat that
resets the body.

Our private infrared sauna penetrates deeper than traditional heat — easing muscles, supporting circulation and calming the mind. Paired with the ice bath, it forms the heart of the Piranhas ritual.

Sessions are private and unhurried. Come alone, or share the room with someone who matters.
