Shark Baby Nursery Theme Decorating Ideas for a Baby Boy's Room

Updated November 7, 2025 by Jan of Unique Baby Gear Ideas

The shark baby nursery theme decorating ideas for a baby boy that we suggest on this page will create a room filled with under-the-sea adventure in shades of masculine blue.   Those of you that prefer a more brighter palette might add schools of colorful tropical fish but for the sake of clarity the focus of this tutorial will be on the formidable and yes, sometimes menacing shark . 

Sharks do not have a reputation of being one of the more friendly fish in the ocean which is perhaps the reason that other fish nursery themes featuring whale decor and dolphin crib bedding rank higher in popularity with new parents.

It is a fact that sharks' reputations were not helped by their behavior in movies like "The Shallows" and even worse, "Jaws" but there is no denying their mystery and appeal.

Go HERE for an EASY DIY Shark Nursery Wall Sign to Make

The shark wall sign is an easy craft project that can be managed by beginners and calls for a relatively limited number of supplies. The demonstration even offers a less expensive method using paper instead of wood. How considerate (and totally awesome?) is that?

There are decals, wooden wall signs and art prints to buy but the thrifty mom will be interested in decorating the nursery wall without spending a bundle.

One of the simplest methods of filling a sea of empty wall space is with photos that you can frame yourself. There are tons of free, high quality photos of sharks that divers are willing to share. Just visit one Pixabay and download the photos of your choosing and frame them using inexpensive, black document frames.
