Location
Right in the heart
of Seminyak.
Located in the heart of Oberoi, Seminyak — a short stroll from the beach and the island’s best cafés and dining.
The Piranhas ritual
Three movements,
one return to calm.
Heat & soak
Begin in the mineral onsen and private infrared sauna. Muscles soften, circulation opens, the mind slows.
Plunge & awaken
Step into the ice bath. A bracing, deliberate cold that sharpens focus and floods the body with clarity.
Recover & restore
Close with massage, breathwork or stillness in the recovery garden. Let the nervous system settle.
What's inside
Everything under one roof.

Why Piranhas
What makes us unique.
By The Oberoi, Seminyak
Set on Jalan Kayu Aya in the heart of Seminyak, steps from The Oberoi and the beach.
Limited guests each day
We cap daily numbers so the club never feels crowded — your recovery, unhurried.
Hinoki-wood ice bath
A traditional Japanese wood cold plunge — colder, calmer and more authentic than a plastic tub.
Two saunas
An infrared sauna and a traditional hot-stone sauna, so you can choose your kind of heat.
7-metre heated jacuzzi
A seven-metre heated jacuzzi lined with natural stones — built for long, slow soaks.
Life Fitness gym
A fully-equipped Life Fitness gym with a premium sound system to train, then recover.
Private
infrared
by the hour
Contrast therapy
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.
Pricing
Simple, all-in pricing.
Pay per visit, grab a visit pack, or go unlimited with membership — onsen, sauna, ice bath, gym and yoga, all in one place.
Inside the club
A space made for slowness.

“Worth every rupiah. I structure my whole week around the onsen and ice bath now.”
“The most calming place in Seminyak. Heat, cold, then total stillness — nothing else comes close.”
