There so many decorating bathroom ideas available in the magazine and internet. But you can try decorating bathroom ideas with seashell. Seashells give your bathroom an instant seaside, beach or nautical vibe, no water required. Seashell decor comes in different designs. For example, a large craft stamp of your favorite style of shell, whether cockle or conch, allows you to create your own stylized border or embellishments on an otherwise plain wall. Coat the stamp with an acrylic paint in a color that stands out, such as white for a navy blue wall, or opt for a subtle effect such as white stamped designs on a sand-colored wall. Stamp a repeating design all the way around the top of the wall for a border, or use an actual wallpaper border featuring shells if you prefer. Create shell-shaped wall decals by cutting the desired shapes out of shelf paper. Give the bathroom a focal wall with one large shell design in the center, created freehand with paint, or with a large stamp or homemade decal. Make your own stamp from a large sheet of shipping foam, carved to look like your favorite shell.
