Create a beachy coastal vibe in your kitchen with a built-in slushie machine. Use a color palette inspired by the ocean, such as shades of blue, white, and sandy beige. Incorporate nautical elements like seashells, driftwood, and rope accents. Display beach-themed artwork, coastal-inspired dishware, and woven placemats. This kitchen decor idea will bring the calming and refreshing ambiance of the beach into your home.
