Create a bold and dramatic kitchen with a nautical navy theme. Paint the walls in a deep navy blue shade to make a statement. Choose white cabinets and countertops to balance the dark color. Add nautical accents like rope drawer pulls, a subway tile backsplash in shades of blue, and a pendant light with a ship wheel design. Incorporate natural elements with a reclaimed wood dining table, woven baskets for storage, and a sisal rug. Hang artwork featuring sailboats or lighthouses to complete the nautical vibe.
