The cooling room of Roman baths, also known as the frigidarium, was an essential part of the bathing experience for the ancient Romans. This room was designed to provide a refreshing break from the hot and steamy environment of the caldarium and tepidarium. The word frigidarium derives from the Latin word "frigidus" which means cold or chilly. Some synonyms for the cooling room of Roman baths include the cold room, the refreshment chamber and the chillout space. The frigidarium was typically adorned with beautiful mosaics, statues, and fountains to add to the relaxing atmosphere. Today, the frigidarium remains an important part of ancient Roman spa architecture and a popular tourist attraction.
