How to Decorate an Under the Sea Room for Kids

Updated April 17, 2017

Transform your child's traditional bedroom decor with an under-the-sea theme. Popular with kids of all ages, an ocean theme is relatively easy to create. Set the stage by changing the floors, walls and windows to ocean hues, and complement them with under-the-sea accessories. Younger children may prefer cartoonish, whimsical versions of sea creatures, while older children may want more realistic depictions of ocean life. Let your child help you decide which decorations and accessories to use for a look that will be enjoyed for years to come.

Paint the walls a light blue or turquoise colour to give the room an underwater feel.

Set a textured green rug on the floor to simulate seaweed. If you have wood floors, stain them a light brown colour to represent sand.

Hang short white valances to suggest foamy waves or green curtains that reach to the floor to suggest tall stalks of seaweed.

Purchase an ocean-themed bed covering in colours that coordinate with the wall and curtains. Alternatively, purchase a solid green or blue bed covering that can be reused when your child grows older and wants a different theme.

Replace existing lamps, light plate covers and drawer pulls with ocean-themed ones.

Stain a wooden toy box dark brown. Embellish it with yellow or gold hinges and a handle to look like a treasure chest.

Create a wall mural depicting sea animals using paint, stencils or self-adhesive appliqu├ęs.

Hang stuffed sea animals from the ceiling or display them in a toy net hung in one corner of the room.

Display shells on top of a dresser, shelf or desk.


Be sure the paint on the walls has dried and cured completely before adding a wall mural.
