WAV Private Onsen

WAV Private Onsen is a Japanese-style private bathhouse on Hai Bà Trưng in District 1, Ho Chi Minh City. The wellness facility operates inside KiN Hotel Onsen near the Saigon Opera House. KiN Hotel Group manages the venue and rebranded it from KUDOCHI Onsen in 2024. Guests reserve individual suites for private two-hour hydrotherapy sessions.

Each private suite contains a hot soak tub, a cold plunge pool, and a wooden sauna cabin. The baths utilize heated mineral water alongside chilled water for the plunge tub. Rooms feature customizable environmental settings for lighting, background sound, aroma, and water temperature. Suite themes take inspiration from natural elements such as stone and earth. The KURA suite showcases dark stone textures with a muted interior palette.

The facility maintains continuous operations around the clock, seven days a week. Visitors access their reserved private rooms using automated digital QR codes. Suites accommodate solo visitors, couples, and small private groups of up to six people. Private shower stations supply bath towels, robes, hair dryers, and grooming amenities.

KiN Hotel includes complimentary private soak sessions for guests staying in select hotel rooms. External visitors book private suites directly through online reservation channels. The venue focuses on contrast bathing therapy through alternating hot soaking and cold immersion. The central location places the facility within walking distance of Lê Thánh Tôn and Đồng Khởi.
