Equus

Equus (에쿠스) is a gay cruise club, not a sauna, in the basement of 545-18 Gangnam-daero on the Seocho side of Sinsa. Travel Gay (June 2026), misterb&b and VAYL all list it, with themed nights such as underwear, naked and S&M parties. It is listed as open 24 hours. Google files it oddly as a bed and breakfast and rates it 3.4 from about 35 reviews. Shelter, Oban and Cuba saunas are all within a short taxi ride.
