A double sink (also called a double bowl sink) is a kitchen sink that has two separate basins side by side.
Main uses:
• Washing and rinsing at the same time — One bowl can be used for washing while the other is used for rinsing.
• Separating tasks — Useful for keeping dirty dishes in one side and clean items in the other, or for washing food in one bowl and dishes in the other.
• Improved efficiency — Allows two people to work at the sink at the same time or handle multiple tasks more easily.
