Coastal decor ideas draw on the colors of sea and shore, littoral textures, and the landscape and architecture of waterside locations, whether on the east or west coast – or more distant shores. 

Think the blues and grays of sea and sky, fresh white, gentle neutrals, and bewitching greens, along with pops of red, navy, and yellow. And add in tactile weathered woods, woven materials and natural fabrics.

Whether it evokes classic Cape Cod house style, a sophisticated beachside vibe, or a more boho look, coastal decor can make interiors feel fresh, open and connected to nature and it’s a great look for any room as well as for outdoor spaces like decks and patios.

'The color palette in a coastal-style home is foundational to achieving the look and feel you want to create,' says interior designer Courtney Wollersheim, from FLOOR360. 

'Start with warm gray, beige, white and ivory as your foundational colors and add a healthy dose of cozy blue and dusty green accents. The overall effect is sunny, soothing, light, and airy.

'Flooring options include hardwood or hardwood-look luxury vinyl plank in a light shade or whitewashed finish of white oak or with visible textured grain.

'Juxtapose smooth lines in couches, chairs, tables and finishes, with chunky textures in baskets and rope or rattan accents.'

From stormy waters to calm seas, golden sands to gray shingle, this is how to create your coastal decor ideas.

Bringing softness and a relaxed, breezy feel, living room curtains in lightweight floaty fabrics are the perfect finishing touch to a coastal decor scheme, plus they can help balance the strong tonal contrasts, too.

'Rare is the coastal home that isn't flooded with light and airiness... it's all about evoking that breezy lifestyle,' says Corine Maggio, interior designer and founder of CM Natural Designs. 'In this room the drapery offers a softening of the otherwise high contrast elements in the space and ties in the light ocean blue of the rug.' 

Although it looks like a solid color, 'up close you'd see that it's actually a thin stripe, which offers a necessary subtle texture since the other large elements, the sofa and chair are solid', she adds. 

Decorating with blue and white, and fitting horizontal wood paneling, makes a great foundation for a coastal living room, but don't forget about the details – light fixtures, accessories and wall decor can all contribute to the look.

In this space seascape artwork and wall lights reminiscent of naval ships both add to the nautical feel, while the gold frame and metalwork also help bring a touch of warmth to the room. Lining vintage bottles along high living room shelving is a great nautical detail which helps lead the eye upwards.

However, be careful to avoid clichéd coastal accents, warns interior designer Allison Babcock. 'Instead choose accessories that have a timeless coastal feel,' she advises. 'While a bathroom with seashell tiles or a living room full of anchors may quickly feel dated, keeping accents simple and natural, like driftwood, seaglass, and stone, means it will never go out of style.'

If you're after a soothing seaside sanctuary then decorating with white is the perfect base. Not only do the white walls in this space ensure a calming feel, they also help focus attention on the beautiful whitewashed ceiling beams which are a beautiful characterful feature. 

When it comes to finishes, to add to the coastal feel, 'look towards using natural materials such as wood against a backdrop of crisp whites and blues’, says Sam Hood, co-founder and chief creative officer of Amara. 'If you don’t like the look of natural woods, whitewashed furniture is a good substitute.'

When creating a coastal interior, 'the focus should always be drawing the outside in,' says Allison Babcock, and with its wealth of natural materials, the interior of her Nantucket coastal holiday home does just that. 

In this open-plan space, a pair of rope armchairs combine with a chunky wood side table and woven coffee table bring warmth and appealing texture to the cool and breezy living room area, while cane bar chairs and wooden open shelves keep the natural materials running through to the kitchen area.

When it comes to complementary hues, 'create a color palette that reflects the coastal nature of the space, whether that's injecting oceanic blues with sandy tans or accenting stormy slate gray with natural linen', says Allison.

Decorating with art is an easy way to introduce a coastal feel, and there are so many inspiring ideas to explore other than traditional seascape paintings. This beautiful series school of koi sculpture brings elegance and movement to this simple dining room and really pops against the navy wallpaper, which features gentle texture reminiscent of shimmering water. 

'The fish art pieces were sourced during the client’s travels. The client knew she wanted to incorporate them into the space but needed a clear vision on how to execute it,' says Stephanie Lindsey, principal interior designer at Etch Design Group. 'As a backdrop for a display of koi fish art, the navy textured wallpaper creates the final element of color.' 

If you can't head to a tropical island, bring the clear blue waters to the island in your kitchen – it's a simple but effective take on a blue kitchen. 

This decor of this villa, designed by Humbert & Poyet, is informed by its location in Cannes, in the South of France. Inspired by the Mediterranean, a blue color palette can be seen throughout the interiors, even here in the kitchen, where it highlights the rosewood cabinets.

The open spaces allow for a natural flow of light, creating a fluid connection between indoors and out. 

The key to coastal living room is creating a light and airy space with light tones and neutral textures for a relaxed feel, then adding accents of bolder color to create lively focal points. Leah Keggi, founder of independent art studio CoastL Studio, explains.

'You can achieve this by focusing 70 per cent of your color (walls, furniture, focal patterns) in a room on lighter blues and neutrals that mimic the color of the ocean and beach. Then add in 20 per cent of greens and greenery, and 10 per cent of smaller decor and patterned pieces featuring richer pinks, corals, or navy.'

Here, weathered walls, natural linen and driftwood furniture and accessories create a backdrop for deep blue accent fabrics.

Don't be scared to take the plunge with deeper nautical tones of navy and inky ocean hues when it comes to creating a blue dining room. This strong palette sits beautifully in an entertaining space where it creates a sense of enclosure and intimacy that works for both day and night.

For a fresh, coastal feel, add in elements of white and cream to lift the scheme. Here, light voile drapes, and whitewashed furniture keep the look beachy.

Wooden panelling can transform the look of a room, and are a common feature of coastal interiors.

'We love to use shiplap in our coastal decor ideas because of the nautical feel it gives,' says Owner/Designer Anissa Swanzy, of SKD Studios in Newport Beach. 'Don't just consider neutral tones; we've painted shiplap navy for a client in a beachfront apartment.

You can defy expectations in other ways, too. Here, the green sofa swerves the usual coastal blue and white palette, but with the nautical pendant light, shiplap and rush lamp, the look puts a new spin on the typical beach look.

Nautical wallpaper and seafaring motifs give a maritime makeover to the usual mud room and make this space perfect for a coastal home.

An entrance space like one, designed by Amy Leferink of Interior Impressions, sets the tone for a home, so the blue and white color scheme with accents of red is just right. To finish, a porthole-shaped mirror hung from a rope, complemented by a striped rug and coordinating towels, create a playful, uplifting space.

For an elegant, subdued take on coastal decor ideas, introduce typical design motifs in an unexpected way. It might be a twist on the usual coastal color palette, or a reinterpretation of pattern and texture, like this velvet headboard in sea-glass green, created by Humbert & Poyet for a villa in Cannes.

'Striped patterns are a nautical staple but bring these in subtly – for example, in cushion covers or delicately striped curtains,' suggests Connor Prestwood, interior designer at home decor brand Dowsing & Reynolds.

'Light blues, whites and hints of yellow are go-to colors for coastal, as they remind us of the beach and the ocean and naturally have a calming effect on us.'

Coastal-inspired decks are a chance to create a visual bridge between a beach setting (or coastal garden planting scheme) and your home. 

On this terrace, designed by Humbert & Poyet, the clear blue couch and tiled floor bring a look of the sea and turn this transitional space into another coastal setting.

Your coastal decor ideas can be as simple as using a color palette inspired by sea and shore, without any obvious nautical references.

'I love coastal designs that emulate the coastal lifestyle and feeling without having a literal interpretation of the coast. So I say, skip the seashell, beach and under-the-water-themed decor and elevate the look,' explains Andra DelMonico and I'm the Lead Interior Designer for Trendey.

'If you do happen to like these motifs, use them sparingly. Focus on selecting a color palette that reflects the type of coastal living you want to emulate. The colors you choose will look very different for a nautical northeastern theme and a southern/Caribbean tropical theme. You can’t go wrong with a white, blue, and neutral combination. 

'Accent the space with natural materials, like teak, acacia, cedar, or redwood.'

The sea and coastal landscapes have inspired generations of artists, so why not use a painterly approach as a canvas for your coastal decor ideas?

Watercolor bedding, wave-patterned wallpaper and artworks with an ocean theme all contribute to this artistic interpretation of the coastal look.

Add in weathered wood furniture and panelling to ground this airy, romantic look.

While too many seaside accessories and trinkets can overwhelm a room, a few carefully chosen accessories can introduce the coastal theme in an elegant way.

Decorate with replica resin shells and coral, or display beachcomber finds such as pebbles, sea glass and shells in glass jars for a subtle coastal decor idea.

Keeping the palette muted will maintain curated look.

Browse coastal markets and antiques stores for interesting decorative finds. 

'Furnishings in coastal rooms often have a nautical feel, with rope accents, seashells, and other beach-inspired details. Decorative approaches can vary from room to room, but often include elements like wicker baskets, driftwood sculptures, and seascape paintings,' says Lily Wili, Founder of Ever Wallpaper.

In this hallway, designed by Amy Leferink of Interior Impressions, rowing oars provide a graphic nautical display that is complemented by the stripes of the rug and  upholstered seat.

All the principles to the coastal decor ideas you bring inside the house, also apply outside on a deck or terrace. In fact, coastal garden ideas will work, just as indoors, even if you don't live at the coast.

'When it comes to coastal decorating schemes, colors play a huge role,' confirms Jen Stark Founder of Happy DIY Home. Think light green and blue hues, bleached whites, and sandy beige tones to mimic the sand and sea look. You can also consider incorporating driftwood browns and grays, beach pebble gray, dune grass green, and the colors you find in seashells. For vibrant hints of color, add orange or yellow to mimic the sun, and the bold reds of umbrellas or shore flowers.'

It's also essential that you narrow down to relaxed simplicity – especially in an outdoor living space. 

'Materials and furnishes that can take wear and tear are key,' says Jen. 'Consider adding streamlined, simple furniture alongside distressed and weathered pieces. Using outdoor fabrics in your rugs or on your cushions is another viable option.'

Ensure, too, that the space feels authentic by incorporating coastal plants.

Use a seashore-inspired color palette to transform simple containers. Boardwalk brown, sandy yellow and sea blue bring the beachscape to your balcony or garden.

For added authenticity, plant them with coastal plants – not only will these suit your coastal decor ideas and scheme, if you are situated by the sea, they will withstand salty air and harsh sea breezes, too.

Interior designers often use an artwork as the basis for a room's color scheme, whether they pick out a single shade or incorporate the entire palette from the picture. This approach works particularly well when you're refining your coastal decor ideas, as you can use the image as your guide. 

'You might choose a seascape of predominantly blue and gray tones, with white crests on the waves. Or look for beach scene that incorporates sea, sand, shore and even people and houses, for a more colorful palette,' suggests Andréa Childs, editor of Country Homes & Interiors.

A bathroom is the perfect space for coastal decor, but you can overdo it, ending up with a space that looks themed. 'I love the approach taken in the bathroom, above,' says Lucy Searle, global editor in chief of Homes & Gardens. 'Red, white and blue is always elegant and smart, and if there is the merest hint of a seaside motif, you can get away with what is quite a traditional approach.'
