When you think of the beach, you don’t think of a clear, straight line — you think of free-moving waves and sands crafted by nature. Bring this organic approach to your coastal bathroom decor for a nice flow in your space.

“When designing coastal bathrooms, I like to choose organic forms such as rounded tubs and sculptural lights (we're in love with this Joss and Main Chandelier from Wayfair),” says Megan Siason, interior designer and founder of M Studio Interior Design.

The best paint colors ideas for bathrooms will help you create a coastal bathroom in a subtle, mood-evoking way.

“Some clients crave a bright and beachy vibe, with light, airy colors that evoke sunny days by the water,” says Rachel Waldron, interior designer and founder of Waldron Designs.

Rachel Waldron is an interior designer and founder of Waldron Designs. She blends sustainability into her commercial and residential designs, drawing from her versatile career spanning kitchen design to diverse commercial projects.

Meanwhile, Rachel says others want a cozy retreat for those rainy days when all you want to do is curl up with a good book and listen to the pitter-patter on the roof. 

She adds, “We design bathrooms which can capture both these moods or anything in between.”

Go for a mixture of navy blues, light blues, and off-white to capture this idea.

3. Be inspired by your favorite beaches

Whether you have a beach nearby or one you long for far away, bringing in the atmosphere and style of it is a beautiful idea.

Rachel explains, “When designing coastal bathrooms, it's important to consider your favorite coastal region and its natural influences. In the past, we’ve incorporated elements reflecting the beauty of the Pacific Northwest — think natural materials like wood and stone, light fixtures which mimic the sun's rays filtering through trees, and calming blues and greens echoing the ocean.”

You could even pick up some driftwood or sea glass from your favorite beach and arrange a vignette, for a subtle nod to your favorite place.

4. Provide discreet storage

All washrooms need bathroom storage ideas, which you can bring into your coastal bathroom decor by playing with nautical-inspired materials.

“Woven baskets and glass containers (we're eyeing up these Tbestmax Cotton Swab Holders which are Amazon's Choice) provide discreet, effortlessly chic storage,” says Kristin Patrician, principal designer and owner of Dwelling Envy Interiors.

5. Enhance natural light

Bring in the feeling of stepping out onto the beach on a bright day by making sure natural light flows through your bathroom.

“I favor open shelving in airy, light wood finishes (we like these solid wood Loon Peak Pine Shelves from Wayfair which come in four colors) and gentle lighting that casts a tranquil glow from glass or linen shades,” Kristin explains.

“An abundance of natural light is non-negotiable, achieved through minimalistic window treatments that invite the sun to play its part,” she adds.

It’s also a good idea to learn how to clean your windows, so as much sunlight can go into your bathroom as possible.

6. Stick on wallpaper

For those looking to add texture and depth to their coastal bathroom, big and small bathroom wallpaper ideas are a great way to go.

“A textured seagrass wallpaper is a great option as it can be either understated and elegant or fun and playful,” says Hanin Smith, principal designer and founder of Hide Studio.

For example, this Bay Isle Home Cloth Roll from Wayfair would make the perfect boho-chic accent wall.

You can choose a sand-toned finish for a more cohesive look or a blue-toned color for a more contrasting effect. 

“It's a subtle way to bring the ocean into your bathroom without being too obvious,” Hanin adds.

7. Keep it simple

The most important thing to remember when it comes to coastal bathroom ideas is to keep the nautical element of it subtle.

Rachel explains, “Forget seashell showers and mermaid motifs — we use color, lines, and shapes to create a feeling of being by the coast, no matter the season.”

She recommends starting with no more than three small coastal-inspired items or one larger statement piece, to keep the space feeling serene and to avoid a cluttered look.

Choosing tasteful features which bring in coastal grandmother design will allow you to create a beautiful bathroom space that transports you to the beach.
