The Ancient Sumerian kitchen would incorporate a coastal Mediterranean theme with colorful tiles and mosaic patterns inspired by the nearby sea. The walls would be adorned with cuneiform writings and motifs representing agriculture and trade. Mediterranean decor such as clay pots, woven baskets, and reed mats would be used to enhance the design. The kitchen would feature a central hearth for cooking and a stone sink for washing dishes. The design would also include open shelves to display pottery and utensils. The overall ambiance would be rustic and earthy, reflecting the ancient agricultural society of Sumer.
