Roman people did not typically have hot baths at home because heating water was difficult. They lived in small apartments with whole families sharing one room, leaving no space for baths. Instead, they visited public baths, which served as community centers with pools fed by aqueducts, hot tubs, exercise areas, gardens, libraries, and theaters. Larger baths in major cities like Rome were impressive buildings with vaulted ceilings, marble walls, and mosaic floors.
