The house was originally laid out as "Badehaus 1". In 1925, the spa administration was established here, replacing the old bathhouse. As the headquarters of the spa development, the spa directors planned the expansion of Bad Sassendorf into a health resort here. Under the new name "Haus des Kurgastes" it was rebuilt and renovated in 1965.
Today, the "Haus des Gastes" is the most important point of contact for all spa, vacation and day guests as "Guest Information", where they can obtain information on the wide range of services offered by the town. Information can be obtained by calling 02921-9433456.
