In this paper, viability of tap aerators application in the example of Priska luxury rooms in Split is explored. Reduced water consumption due their application was expected. However, accommodation renters usually question their profitability and their effect on overall guests’ satisfaction. Thus, return on investment period was calculated and it was determined whether there was a significant difference in satisfaction with the water flow between respondents who were in a period when there were no aerators installed and respondents who were staying in a period when aerators were used. Data collection was conducted over a period of 2 months. Water consumption was measured without the use of tap aerators in June 2018, and with tap aerators in July 2018. In addition to arrivals and guest nights, average water consumption per guest per night was calculated. The hypothesis was accepted that there was no significant difference in the average satisfaction of the respondents who stayed in June and the respondents who stayed in July 2018. It was concluded that it is entirely justified to use aerators in hospitality. Except for advantages of using them for their own purposes, the application of the aerators does not lead to a decrease in the level of satisfaction of the guests. Because of the stated facts above, research can be useful to all stakeholders within the private accommodation sector. In order to get a clearer picture of this topic, future research should explore the justification for investing in similar savings measures, both in the case of economic entities and households. A more comprehensive analysis of guest perceptions as well as employees regarding long term resource saving would contribute to an increase in a number of users of various measures as well to environmentally responsible business in general.
