When selecting coastal wallpaper for your bathroom, consider the following:

Bathrooms are high-moisture environments, so its important for it to be well ventilated and to use high quality wallpaper. There are good options out there with tiles and acrylic splash-backs to protect the wettest areas near a shower or above a sink. You can also ask if the wallpaper you have fallen in love with can be printed using a coating. At Milola Design we are happy to discuss the various options with you. 

Coastal Colour Palette

Opt for a colour palette that reminds you of the sea and shore. The best colours for a beach style bathroom are often soft blues, aquas, seafoam greens, sandy beiges, and whites. These pale hues not only reflect the coastal vibe but also make the bathroom feel more spacious and airy. Having said that, don't shy away from a pop of pink or adding a tropical colour which could add the whimsical chic style that you are looking for.

Coastal Patterns

Look for wallpaper patterns that incorporate seaside and coastal elements such as coral, seashells, fish, waves, and other nautical motifs. These designs can range from subtle and sophisticated patterns to bold and whimsical wallpaper designs, depending on your personal style.

Popular Coastal Wallpaper Styles

Blue and White: Classic beach house decor! Pale blue and white wallpapers create an elegant, crisp and clean look. This style works well in both traditional and modern bathrooms.

Sea Life: Wallpapers featuring fish, seashells, lobsters and other marine life can add a playful touch to your bathroom interior, perfect for a family bathroom or kids bathroom.

Textured Effects: If you’re looking for a more subtle approach, consider wallpaper that mimics the colours, textures and elements found at the beach. These designs add depth and interest without overwhelming the space with pattern.

Bold & Bright Colours: Don't be afraid to break away from the classic pale blues and sandy tones. Beach houses are all about vibrancy and fun. 

Bright tropical colours to uplift and add a shot of dopamine to your decor. Bold wallpapers work especially well in small bathrooms like downstairs loo’s, powder rooms and cloakrooms. Here's some ideas to embrace a more tropical beach aesthetic with a splash of bold and bright coloured wallpaper patterns.

Patterns that Pop: A bold coastal wallpaper pattern in an unexpected colour such as hot pink or bright blue adds a touch of whimsy and fun. We love how this tiny bathroom has been transformed with our Lady Lobster wallpaper in pink.

Oceanic Azure: Embrace colours and depth of the sea with a bold blue hue. A deep azure or seemingly translucent turquoise or aqua creates a dramatic yet sophisticated atmosphere. Use with white wainscoting for a touch of coastal charm and balance the intensity.

Coral Paradise: Bring the vibrant life of the coral reef into your bathroom. A playful warm coral pink or orange paired with crisp white can create a modern yet elegant coastal style bathroom interior.

Other ways to use coastal wallpaper

While wallpapering the entire room may maximise the effect, wallpaper can also be used in other ways to make your bathroom look more beachy and are the perfect ways to use up any half used rolls of wallpaper.

Wallpaper the Ceiling: For an unexpected twist, consider wallpapering the ceiling.  A water like pattern to give the illusion of looking up into the sea. 

Wallpaper Small areas to add interest: A good way of using up any left over wallpaper is using it to create a feature in smaller spaces like behind open shelving, inside cupboards, or make into a room accessory such as a waste paper bin or a lampshade to add a pop of coastal charm without it dominating the room.
