Coastal Bathroom Decor: A Complete Guide to Creating Your Perfect Beach-Inspired Sanctuary

Hey there! I’m Sarah, an interior designer specializing in coastal spaces, and I’m excited to help you transform your bathroom into a serene coastal retreat.

Let’s dive right into creating that perfect beach bathroom you’ve been dreaming about!

Why Go Coastal?

I’ve found that coastal bathrooms are perfect for:

  • Creating a spa-like atmosphere
  • Making small spaces feel larger and airier
  • Bringing vacation vibes into your daily routine
  • Adding timeless appeal to your home

The Essential Elements

1. Color Palette

Your foundation starts here:

  • Ocean blues (from pale aqua to deep navy)
  • Sandy beiges
  • Crisp whites
  • Soft sea glass greens

Pro Tip: I always recommend starting with a 70/20/10 rule – 70% neutral, 20% main color, 10% accent.
