Peaceful spa with attentive staff. Beautiful waiting area with welcome drink before treatment. The therapist is well trained and polite. There is a small refresh snack and hot drink after the treatment as well. The price is a little bit pricy but it s worth for.

We’ve been to many spas across Bangkok and Opium is the best to us. It’s in a beautifully designed and decorated hotel (The Siam). Therefore, it has a unique and relaxing ambiance. Additionally, it is one of the few spas to have a shower/steam room inside the private spa suite. Finally, we keep regularly returning to Opium Spa because of the staff. They are very friendly, down-to-earth, and expertly trained in all types of massage techniques by Sodashi. We look forward to them pinpointing our tightness/soreness and working them out. All in all, I think Opium Spa is a hidden gem within the incredible Siam Hotel. Given its easy shuttle boat access, it isn’t just for hotel residents. It is for anyone craving a relaxing, deep massage combining unique techniques, beautiful surroundings, and a staff that treats everyone like family.

ホテルに宿泊した際にボディのトリートメントで利用しました。インテリアや雰囲気が本当に素敵なスパです。バンコクにあるスパの中で一番好きな場所です。技術も接客も良いのでオススメです。スパだけの利用も可能とのことでした。併設されているシャワールームにある休憩できるスペースもゆっくりできてとても素敵なのでぜひ行ってみてください。他に美容室などもあり、デザインやセンスが素晴らしいです。

ムエタイマッサージをしていただきました! ジュースでもてなされて、足をお湯で温めてもらい、スクラブで足元をきれいにしてもらって、揉んだり伸ばしたりと、ひたすら気持ち良いひととき✨ サウナは無料で利用できるが10:00から20:00まで。
