Entry No. 41 — the Indianapolis file — filed under: contrast therapy
SWTHZ Broad Ripple
A contrast therapy studio offering private suites equipped with 170°F infrared saunas, 48°F cold plunges, and specialized vitamin-C showers.
The story
If your idea of recovery involves subjecting your nervous system to aggressive thermal shock in complete isolation, tucked away inside Suite 500 on North College Avenue is a precise bit of modern self-flagellation. Built out across 2,184 square feet in Broad Ripple, SWTHZ strips away the social bathhouse communal vibe in favor of dark, sound-insulated private suites.
The setup relies on a cold-blooded math equation: dry infrared saunas cranked up to 170°F force deep body sweat, paired directly with private tubs chilled to a ruthless 48°F. To cap off the vasodilation routine, each suite includes a specialized vitamin-C shower engineered to neutralize chlorine and calm heat-stressed skin. You aren't here to linger in a lounge; you come to sweat, shiver, and disappear.
What it's like
Stepping off College Avenue into the minimalist lobby, the goal is getting you behind a locked door as fast as possible. Inside your private suite, you control the cycle: bake under the infrared glow until your brain surrenders, plunge straight into the 48°F ice tub to restart your heart, and finish under the citrus-infused shower. Bring slide sandals, leave your phone in the basket, and give yourself five minutes to stop shivering before heading back into the Indy traffic.
The move: Book a 60-minute private suite for two, alternating between high-heat infrared sweating and cold plunging, ending with a skin-soothing vitamin-C shower.
