In order for the Thai spa industry to attract more foreigners from different countries, this study attempts to explore the communication skills and problems of spa therapists across Bangkok to better serve the needs of foreign spa customers. Foreign spa customers have been randomly given structured questionnaires and interviewed for specific crucial data about the communication skills and problems that most spa therapists often have. With the use of the TOEIC and IELTS Score Descriptors as the benchmarkers for most of the questionnaire items, it was found that the level of English of most spa therapists in Bangkok is at the medium level. Ultimately, their listening and speaking skills need considerable improvement. In addition, grammar, reading, gestures, and cross-cultural awareness, along with the spa therapists’ needs regarding their English competency are necessary to be included in the communicative framework, which can be used as a guideline for developing an English for Spa curriculum. Consequently, Thai spa therapists will be able to communicate in English more effectively and better serve the needs of foreign spa customers.
