This study compares how that problem is managed in two contrasting institutional settings and asks what each can learn from the other. The study adopts a qualitative comparative multiple-case design (Yin, 2018) following a most-different-systems logic. Ten purposively selected bathhouses five in Istanbul, Türkiye, and five in Khorasan Razavi, Iran are analyzed against six management indicators derived from conservation doctrine and the adaptive-reuse literature: institutional–social participation, functional revitalization, physical authenticity and spatial integrity, compliance with conservation standards, monitoring and control, and managerial–economic sustainability. Each case is rated on an explicit four-level rubric using triangulated documentary, technical and field evidence. Findings show, the two settings diverge systematically. The Istanbul cases score higher on functional revitalization, compliance and economic sustainability, sustained by public–private partnership finance, digital survey and modelling technologies, and integration with the tourism economy, but they carry the risk of over-commercialization. The Khorasan Razavi cases retain material authenticity through minimal intervention, vernacular materials and public stewardship, and sustain a strong cultural and ritual bond, but are constrained by financial fragility, weak monitoring and the absence of comprehensive adaptive-reuse planning. The results show transferable scoring rubric for bathhouse revitalization management and an integrated model that treats historical authenticity and economic viability as jointly binding constraints mediated by a values-based judgement, rather than as a trade-off along a single axis. https://www.ijumes.com/article_737719_9bec7d7247f2ae44996d1bc31efd5219.pdf
