Those are some tips for having a beach themed bedroom. You can make the rest as your designing taste. The important thing is that to have a maximum result, just visualize the beach you want to look and applying the possible aspect you can work out.
Last but not least, get additional ornaments that have coastal impression, for example, seashells that you can display on the bedside table. For you who have surfing hobby, why don’t you put your old surf-board on the corner of the room? Or maybe any other souvenir you have from your trip to the shore would also do.
Next, pay attention to the furniture of the bedroom. It would work well when your background color is supported with the right furniture. You can start from the bedding. Instead of having plain bedding, you can add some pattern that deepens the beach impression. Combine white plain bedding with pattern fabric blue pillow or polka dots bed sheets with lime and blue combination. For your kid’s bedroom, you can pick blanket or bed cover with fish or starfish pattern on it. Another one is that the cabinetry. Having more natural furniture would give more impression. Try light wooden furniture for your cabinet and dresser.
