Diora Onsen & Spa Sathorn is a wellness space that blends a Japanese-inspired atmosphere with calmness and premium comfort in the heart of Sathorn. Located at 117/1 Soi Suwan Sawat, Thung Maha Mek, Sathorn, Bangkok, and conveniently close to MRT Lumphini/Khlong Toei, the space is easily accessible for city-based guests.
The project features five fiberglass onsen tubs with tiled finishes, along with a cold plunge, sauna room, and steam room, all designed to suit the space in terms of function, visual harmony, and guest experience.
The system supports water circulation, filtration, water treatment, heating, and maintenance, creating a complete wellness environment that meets both practical needs and the standards of a premium business. The result is a wellness space that brings together onsen, sauna, and steam in one complete, calm, and distinctive atmosphere.
The Challenge
The challenge was fitting multiple onsen tubs all while maintaining the premium aesthetic and seamless guest flow expected of a city wellness business. Every system had to be concealed, functional, and service-ready without compromising the interior experience.
The Result
A complete multi-zone wellness facility operating within a compact urban footprint — five tiled fiberglass onsen tubs, cold plunge, sauna, and steam room running as one integrated system — setting a clear standard for premium onsen businesses in Bangkok.
