Bangkok Private Onsen | Exclusive Onsen Experience at Once Upon A Thai Wellness
At Once Upon A Thai Wellness & Spa, we understand that a truly luxurious onsen experience requires both privacy and impeccable cleanliness. Our private onsen facilities are designed to provide you with an exclusive retreat where you can unwind and rejuvenate in absolute tranquility.
Our commitment to hygiene ensures that each onsen is used by only one guest or couple at a time, with water that is never reused. This meticulous attention to cleanliness guarantees a soak with complete peace of mind.
