To make a kitchen island with a sink, start by planning the island’s design and layout. Measure your kitchen space to ensure the island will fit and provide adequate clearance. Install the base cabinets and countertop, then cut out an area for the sink. Secure the sink in place and connect the plumbing. Ensure proper support for the sink and finish with backsplash or decorative touches.

Building a kitchen island with a sink provides added functionality and can enhance your kitchen's layout. Benefits include additional workspace and storage. Challenges include precise measurements and plumbing connections. Proper planning and installation are key to achieving a functional and stylish kitchen island.
