Riviera Health Spa (Torrance)

The 30,000-square-foot space divides into co-ed communal lounges and gender-segregated bathing quarters where swimwear is barred. Beyond the thermal pools and deep-heating Hwangtobang clay rooms, the ritual revolves around hands-on bodywork, particularly traditional Korean body scrubs and massages. Uniform shirts and shorts are supplied for wandering the shared wellness areas between heat sessions.
