tepidarium
A tepidarium is a warm room found in ancient Roman baths, designed for relaxation and socializing. It typically features heated floors and walls, providing a comfortable environment for bathers to acclimate before moving to hotter areas like the caldarium. The temperature in a tepidarium is usually around 30-40 degrees Celsius (86-104 degrees Fahrenheit).
In addition to its warmth, the tepidarium often includes benches and decorative elements, such as mosaics and frescoes. This space served as a transition area, allowing bathers to enjoy a gentle heat while preparing for the more intense heat of the steam rooms or saunas, enhancing the overall bathing experience in Roman culture.
