Baths appeared in Greek and Roman times at the site of Amheida at Dakhleh Oasis and Marina El Alamein at the Northern Coast. Bath should be called a balneum and a thermae. Thermae often occupied a whole city. They were ordinarily built by the state or the city, unhampered by budget considerations. Balneae, privately owned, and fitted into city lots as best they could.

The public bath at Amheida was built on the natural cemented dune. We still have no precise evidence for dating the foundation of this bath, which was abandoned and renovated to become a new smaller bath in the second half of the fourth century. the process of building the bath has passed through three stages and contains approximately thirty-two rooms including rooms for cold, hot and dry water and rooms for sitting.

As for Marina El Alamein site, two limestone baths were discovered, one of them called the northern bath dating back to the Hellenistic era and the other, the southern bath dating back to the Roman era was built in two stages. The baths were discovered in 1986 by the Polish mission. The Roman Baths occupy 22.88 meters in width and are about 32.80 meters long.
