This study investigates the reinterpretation of properties of traditional Ottoman hammams in the interior design of contemporary hammams within Istanbul’s luxury hospitality sector. Rooted in a tradition that spans from Roman and Byzantine bathhouses to Ottoman architectural refinement, hammams have historically served as vital social and cultural spaces in Turkish life. Today, many high-end hotels in Istanbul integrate these historical references to evoke a sense of authenticity, heritage, and luxury. The research focuses on 5-star hotels chosen in the historic center and the Bosphorus waterfront of Istanbul. Based on a Purposive Sampling approach, data was collected through visual analysis integrating the Convenience Sampling methodology. The findings reveal that while some design elements—such as domes, marble finishes, and geometric tilework—closely mimic historical precedents, others are subtly adapted to meet modern expectations of comfort, functionality, and aesthetics. This study highlights the dynamic balance between authenticity and innovation in contemporary interior design. It contributes to the broader discourse on cultural continuity in hospitality design and offers insights for incorporating historical narratives into modern interiors.
