Why Coastal Colors Matter in Bathroom Design

Your bathroom isn’t just a functional space—it’s a personal sanctuary. Coastal color schemes transform ordinary bathrooms into tranquil escapes that whisper of ocean breezes and sandy shores.

The Perfect Coastal Color Palette Breakdown

Blues: The Heart of Coastal Design

Blues are the superstar of coastal palettes. From soft aqua shower curtains to deep navy accents, these shades capture ocean essence:

  • Light Aqua: Think Behr Watery, soft and dreamy
  • Mid-Tone Blues: Sherwin-Williams Sea Salt, calm and sophisticated
  • Navy Accents: Bold, dramatic, anchoring your design
