When traveling in Thailand, after visiting the pier night market and Chatuchak Market, your final stop should definitely be a massage！ Thai massage is one of the most anticipated highlights for many travelers visiting Southeast Asia. Thai massage shops are everywhere on the streets, with prices ranging from 300 to 3,000 Thai baht. If you have the budget and want to experience a luxurious massage treatment, you must come to this hot spring spa.

Unlike the dimly lit traditional Thai massage shops, the spacious wooden-toned area here has a very “Muji-style” vibe. This place not only offers massage services but also allows you to soak in hot springs！ Let’s Relax, established in 1998, is a well-established spa brand. It was the first to combine the concept of hot springs with Thai massage, allowing guests to relax their bodies in the hot springs before enjoying a massage. This has unexpectedly become a major attraction.

Let’s Relax Onsen is tucked away in a Bangkok hotel building, featuring gender-segregated hot spring pools (both hot and cold), a steam oven, and multiple spa facilities. Soaking in the hot springs before getting a spa treatment enhances the relaxation effect, completely wiping out a day’s fatigue. The private spa rooms are scented with aromatherapy, allowing you to fully unwind with your eyes closed. After the spa, the shop also provides snacks and freshly squeezed juice, offering a luxurious top-tier massage experience—perfect for when you want to indulge once in a while.
