In this study, spatial characteristics of the historic baths in Urla-Seferihisar region, İzmir belonging to the Turkish period are investigated. The methodology includes documentation of the baths with the tools of the discipline of architectural restoration, historical and archive research, development of tables for analysis of spatial characteristics, visual analysis of spatial characteristics and their alterations via mapping, presentation of schematic restitution plans and evaluation of typologic characteristics. It is concluded that single baths with the rectangular sıcaklık with two halvets plan scheme are widespread in the region. The overall plan layout is always linear, while spaces are brought together in additive fashion. The circulation scheme is generally L formed in order to achieve privacy at the main entrance and terminates in alternating order. The silhouette is generally a composition of one large cubic mass, one group of small cubicals and a prismatic mass addition of another prismatic mass or reduction of the large cubic mass is possible in relation with the desired scale. In turn, types with ılıklık and without soyunmalık are created.
