In this study, I considered the use cases of the Suanbo Spa during the Joseon Dynasty and the location of Onjeongwon, which was a public facility for spa. The study on the suanbo spa has been organized to a certain extent through the annals of the Joseon Dynasty and various supports. But the section on the actual use cases of spa was not covered. Therefore, this article compiled examples of individuals' use of the suanbo spa from individual collections and records of the Joseon Dynasty I checked 18 cases of the actual use data from Yeonchangwi Ahn Maeng-dam(1453) of the 15th Century to Jeong Gi-hyeon and Lee Min-hyung(1871) of the 19th Century. And I looked at each case, separated by centuries. As a result, I was able to identify specific situations regarding the actual use cases of suanbo spa. I could also see the variety of uses and the growing popularity of suanbo spa in each period. By adding actual use cases in the theorem of the suanbo spa history, more empirical and concrete research could be carried out. Onjeongwon is a subject that has not been addressed in previous research. Onjeongwon, a public facility for the use of suanbo spa, was installed and operated continuously. But even that location remains out of the spotlight. Based on the records of “Sinjeung Dongguk Yeoji Seungnam” and “King Sejong's Treatise on Geography”, the locations and sizes were identified around compassion. And in its current location, which was surveyed in 1914, the 211 Oncheon-ri space was estimated to be the space. Recently the inn building in that space has been torn down and now 3/5 is shown as vacant. Verification work through excavation needs to take precedence. Suanbo spa are one of the most important places in Korea's spa history. I hope to contribute to the more faithful description of the suanbo spa histroy. In addition, with the opening of a new suanbo-station on the Jungbu inland railway, I hope it will help the residents of the suanbo spa to reassess their own pride and values.
