SWTHZ The Marina

2298 Lombard St, San Francisco, CA

SWTHZ The Marina is part of the SweatHouz private-suite chain, bringing the infrared-and-ice contrast ritual to San Francisco’s Marina District. Instead of communal rooms, each booking reserves a private suite outfitted with its own infrared sauna, a cold plunge, and a Vitamin C-infused rain shower-letting guests run their own heat-and-cold cycle in complete privacy. The clean, modern design and self-guided format make it easy to drop in for a focused 60-minute reset. The private-suite model is built for people who want the recovery benefits of contrast therapy without sharing space-couples, solo visitors, and anyone who prefers privacy over a communal scene. Memberships and packages make repeat visits affordable, and the appointment-based booking keeps the experience efficient and predictable. For Marina-area locals seeking a sleek, no-fuss infrared-sauna and cold-plunge session on their own schedule, SWTHZ delivers a polished, private take on contrast wellness.
