1/0 Sauna BKK

1/0 Sauna is a sleek, minimalist gay sauna that opened in 2025 in the heart of Silom's gay town, spread over six floors and sharing a building with the gay-friendly Togayther Hostel, so you can roll out of bed and straight in. The basement holds a large bath, showers, and the sauna, with a bar area a few floors up and a straightforward cruise maze throughout. Its standout touch is a color-coded wristband system that signals what you're looking for, cutting out the guesswork. Clean and contemporary with friendly staff, it draws a young East and Southeast Asian crowd of locals and travelers, and guests staying at the attached hostel get in free.
