What was the Great Bath at Mohenjo-daro used for?

The Great Bath at Mohenjo-daro is an ancient structure dating to the 3rd millennium BCE, and while its exact purpose remains unknown, it is generally believed to have been used for ritual bathing.1

Located within a large citadel complex, the structure features sophisticated brickwork sealed with bitumen to ensure water retention. Its design, which includes flights of steps for entry and an advanced drainage system, reflects the high priority the Indus civilization placed on sanitation and cleanliness. The presence of this bath, alongside the prevalence of private washrooms in many homes, suggests that water-related practices were a significant aspect of their culture.12

Please note that the Great Bath at Mohenjo-daro is distinct from the Roman-era Great Bath located in Bath, England, which served as a public social and bathing facility.3
