Decaying Bathrooms by cell biologist and photographer Ralph Graef is a compilation of the bathrooms he encountered while shooting his Vacancy series featuring abandoned buildings, manors, hospitals and barracks. Many of them still appear to be useable, and he was particularly drawn to their designs. Aside from his abandoned series, Graef’s photography also focuses on landscapes and contemporary series shot on both analog and digital formats, which have gained recognition in both national and international photography contests.
