In a rustic two-tone kitchen, adding an island with a waterfall marble countertop can create a beautiful contrast between natural elements and luxurious materials. The upper cabinets can be made of reclaimed wood or have a distressed finish, while the lower cabinets can be painted in a warm earthy tone, such as olive green or burnt orange. The waterfall marble countertop adds a touch of elegance and refinement to the space. The combination of the rough texture of the wood and the smooth surface of the marble creates a visually interesting and harmonious design. This type of kitchen design is perfect for those who appreciate the charm of rustic aesthetics but also want to incorporate a touch of luxury. The island with a waterfall marble countertop becomes a focal point that brings together the different design elements and adds a sense of sophistication to the kitchen.
