SWTHZ Pasadena

173 S Lake Ave, Pasadena, CA

SWTHZ Pasadena brings the chain's private contrast-therapy concept to South Lake Avenue, with sealed 60-minute suites that pair a high-heat infrared sauna with an in-suite cold plunge. Every session is fully private — no sharing, no scheduling around strangers — which is the entire appeal for regulars who want contrast therapy without a gym or spa atmosphere. The studio runs on a simple booking model: pick your suite, bring a friend if you want, and you get the room for the full hour. Amenities are minimal by design (showers, towels, product), keeping the experience focused on the sauna and plunge cycle itself. Good fit for couples, busy professionals, or anyone who wants contrast therapy without the distractions of a bigger facility.
