Bring a rustic touch to your beach house kitchen with a coastal theme. Opt for weathered wood cabinets and a reclaimed wood dining table to create a rustic look. Paint the walls in a neutral color like beige or light gray. Incorporate seashell accents by using seashell-shaped drawer pulls or a seashell-inspired backsplash. Add coastal colors with blue or green dishware and textiles. Enhance the rustic beach house vibe with vintage coastal signs or driftwood wall art.
