Once Upon A Thai Spa (Phrom Phong)
8 7 Soi Bannasan, Khlongton Khlongtoey Bangkok 10110
Lead with the aromatherapy treatment: each private room features a built-in shower, Dyson hair dryer, and 100% natural essential oils blended with sweet almond oil. Sessions close with complimentary homemade gelato and herbal tea, which is a thoughtful, uncommon finishing touch. Built for guests who want a complete sensory experience rather than a quick rubdown, this is a genuine step above the neighbourhood average.
You arrive at a serene, Thai-inspired interior where soft natural music, carefully chosen aromatic oils, and a considered aesthetic combine from the moment you step in. Once Upon A Thai Spa (Phrom Phong) positions itself as more than a massage venue: it frames each visit around the five senses, drawing on Thai arts, cultural motifs, and natural remedy traditions to create what the brand describes as a multi-sensory experience.
The spa holds the distinction of being the first in Thailand to formally integrate Thai arts, culture, and beliefs with natural traditional remedies as a core concept. That heritage shows in every detail: essential oils are sourced through 100% natural plant extraction and blended with vitamin-rich sweet almond oil, then applied by therapists trained to adapt strokes and pressure to each individual guest.
Private treatment rooms each include an en-suite shower, so you can refresh in full privacy after your session. Dyson hair dryers, a personal comb, and personal care products made with 100% natural ingredients are provided as standard amenities. After treatment, guests receive complimentary homemade gelato in flavours such as mango sticky rice, coconut, and Thai tea, paired with a selection of herbal drinks.
The service menu spans traditional Thai massage through to aromatherapy spa treatments, with therapists adjusting each session to address stress relief, muscle tension, or general relaxation depending on your stated needs. The atmosphere is designed as a quiet contrast to the Sukhumvit bustle outside: the branch is located on Soi Bannasan, roughly five minutes on foot from BTS Phrom Phong, and sits opposite EmQuartier mall.
With a 4.9-star rating from over 4,200 Google reviews, the Phrom Phong branch consistently draws guests who return specifically for the aromatherapy programmes and the quality of the finishing touches. Advance reservation is recommended.
