The valorisation of healthy lifestyle has indicated the dynamic increase of healthcare sector. The consumer behaviour has been forming deterministically in health tourism. Visitors of spa towns can select various combinations of services either to sustain ...their health, to rest, to relax or to recover. It has a great importance for spas offering complex health tourism services to know the demands of guests and to reach the target groups with special, personalized service packages. After considering the statistical indicators of tourists visiting the spas of Northern Great Plain Region and the competitors of a selected spa, this paper aims to investigate the coherence among bathing habits, influencing factors of service demands, age and non-motivating coherences. The survey was taken place in a selected spa in Hajdú-Bihar County in August 2018 with random sampling questionnaire involving 256 visitors. During data analysis the coherence among indicators was examined with variant analysis (Levene’s test), in case of significant result with Welch’s t-test. Variances in age groups were analysed with Tamhane’s and LSD tests (post hoc analyses). We concluded that the primary information source of spas is still the suggestion of friends, acquaintances independently of the age of the respondent. Knowing this is relevant for further marketing communication. The most important features among the respondents are the condition of the spa and cleanness which are the basics of quality services. Motivations with coherence to age are social life and gaining experience, recovery and disease prevention. Visitors have the largest interest for family and kid programs. Recognition of bathing habits helps in marketing communication, reaching target markets effectively, pricing and service developments as well.
