Did the Ancient Greeks develop thermal bathing?

Pardon my ignorance, but I thought the Romans were pioneers of thermal bathing and bathing systems in general.

James Bond wasn’t the first to enjoy the benefits of a shot of cold water. In ancient times, hot water was a luxury. People had to live near a hot springs in order to enjoy the comfort of a hot bath, so for most of human history people bathed in cold water. But even when the Ancient Greeks developed heating systems for their public baths, they continued bathing in cold water for the health benefits. The Spartans, hard-asses that they were, felt hot water was for the weak and unmanly. When they did take baths (which was, like, once a year) they used only cold water because they thought it tempered the body and made it vigorous for ass kicking.

yes there are natural springs in Greece but again I thought developing heating systems was a Roman invention.
