The Historical Bath of Siba – Hamam Sibah (Persian: حمام سیبه), is a historical bathing complex of the ancient Sassanid culture, located in present-day southern Iran near the Straits of Hormuz.

Ancient Sassanians built public baths to serve as rest centers.

The baths served Sassanid government officials, the merchants from nearby sea ports and desert caravan routes, and the public.

Some of the baths had practitioners who offered healing treatments, using medicinal herbs and essential oils.

The baths were known as the 'dumb doctor' because healers also treated patients silently with its healing hot spring waters.
