DIY Under the Sea-Themed Kid's Bathroom


With our little girl arriving in December, I decided to turn our "grown up" guest bathroom into a special under-the-sea-themed kid's bathroom. To do so, I painted the existing board and batten, baseboards, and crown molding an ultra white and painted the walls a colbalt blue.
After the base coat was completed, I went online and Googled images for coral and sea animal silhouettes. The idea was to make this bathroom as whimsical as possible, so I chose a variety of coral species and familiar animals, such as a sea turtle, Caribbean reef shark, jellyfish, fish, and manta ray. Once all of the items were chosen, I traced them directly onto overhead transparencies with a Sharpie. You could also print them out onto printable transparencies, too.
Then, using a school overhead projector (which we bought off of eBay for $15), I projected the images onto the wall to figure out where they should go.
I traced the items directly onto the wall using a piece of chalk. I wanted the coral to overlap in some places, so I traced them one at a time, painted the coral with a large-sized paint brush, and then traced the other coral over top.
All of the sea life was painted in a variety of colors.
And here's the final reveal!
The room is now bright, whimsical, and perfect for our little girl. I hope it'll fuel her imagination and inspire creativity in the years to come. Hope you love it as much as we do!

      I understand the toilet paper as I had 2 granddaughters that when they came to my house around age 2-3 loved to unroll the tissues all over the floor, they laughed so much

    This room looks so dark. Did you take the pictures at night? Are there any windows?

      I think because the bathroom has no ceiling light fixture. It looks like the only light source is the vanity lights on the wall. It definitely needs a fixture installed on the ceiling so the light can be evenly distributed, especially since children are supposed to be using it eventually.

    This looks great, better than the over processed looks I usually see. Thanks, the blue is lovely.
