Coastal Bathroom Decor Ideas to Inspire Your Powder Room Refresh

Powder rooms are one of the easiest spaces to update, and they’re the perfect spot to try something a little more styled or fun! I designed this modern coastal look using soft blue colors, warm natural textures, and architectural details like beadboard paneling and blue and white wallpaper. These small touches give the space structure and depth while keeping it feeling clean, light and relaxed.

From the rattan mirror and scalloped towel to the bronze faucet and decorative hydrangeas, this coastal bathroom design is the perfect blend of casual and polished. It’s a great example of how coastal bathroom decor can feel elevated without being overly beachy. If you’re working on decorating a beach house or your year-round home, this look is full of simple, versatile coastal bathroom ideas you can make your own.

This bathroom mood board is meant to inspire you to create a powder room that feels perfectly you. You can easily personalize it by picking a coastal wallpaper you love, swapping in a round mirror, or choosing hardware in a finish that fits your style.

In this bathroom mood board, the beadboard paneling, wallpaper, woven details, and natural finishes bring in coastal-inspired textures that all work together.
