Transform your kitchen into a coastal oasis by incorporating under-cabinet lighting. Install soft blue LED lights to mimic the calming effect of ocean waves. Pair the lighting with white cabinets and light-colored countertops to create a bright and airy space. Add beach-inspired decor such as seashells, driftwood, and nautical-themed accessories. Use natural materials like rattan or wicker for chairs and bar stools to complete the coastal look.
