What were the main water temperatures featured in Roman baths?

The main water temperatures featured in Roman baths included hot, warm, and cold, which is why this answer is considered the most comprehensive. Roman baths, or thermae, were complex structures that not only served as places for bathing but also as social and recreational spaces. The typical layout included various rooms with specific temperature settings: the caldarium (hot room), the tepidarium (warm room), and the frigidarium (cold room).

The benefits of using multiple temperatures were significant; the transition from hot to cool would stimulate circulation and promote relaxation. Therefore, the inclusion of all three temperature variations was essential to the Roman bathing experience, offering a full sensory and therapeutic journey for bathers. The other options either lack the full range of temperatures (such as only cold or just warm and cold) or do not acknowledge the importance of the hot water functionality in these baths.
