SpongeBob Bikini Bottom Leggings

Educational resources & donation included with every purchase. Learn more.

SpongeBob was created by marine biologist Stephen Hillenburg, who used art to teach kids about the marine species and ecosystems around them. With its origin in marine science education, the series has always had a deep-rooted connection to the sea. This connection led Paramount and Nickelodeon to launch SpongeBob SquarePants: Operation Sea Change, a global conservation and sustainability initiative to help protect the home of the very creatures that inspired Bikini Bottom. We created this collection in partnership with Paramount Consumer Products to support the Operation Sea Change initiative as well as advocate for the importance of art in inspiring environmental stewardship.

Advocate Apparel Inspired by the Bikini Bottom Ecosystem

The SpongeBob SquarePants creative team did such an incredible job designing the ecosystem of Bikini Bottom with its distinctive bright colors, iconic flower-shaped clouds, and buoyant mood that our team wanted to embody it when designing the SpongeBob Bikini Bottom collection. Although a fictional world, Bikini Bottom and its citizens are inspired by real underwater critters and places, many of which can be found in the intertidal zone.

Besides being huge fans of the show for its creativity, positivity, and forward-thinking themes, we love SpongeBob SquarePants as an example of how art can support environmental science and conservation. Art can provide an opportunity to instill emotion and humanity into science communication while maintaining its scientific integrity. Art can speak for animals, ecosystems, and communities who may not be able to speak for themselves. Art can transform apathy into enthusiasm, enthusiasm into action, and action into change. And in special cases when an artistic expression becomes widely popular like the animated adventures of a charismatic sponge, it can inspire an entire generation.

Who live in a pineapple under the sea?

I am 60 years old and I do not like to show my white 60 year old legs at the pool at the gym.  I have tried other brands of swim pants and the have not fit right :(  I love to two pairs that I purchased from Waterlust!  I wore my SpongeBob outfit to my water Pilates aerobics class last night and everyone was asking where I had bought the outfit from.  I got sooooo many compliments :)  One thing I would like to suggest about the tops, I am a two time survivor of breast cancer and because of that I have one breast that is larger than the other. I would love it if you had the option to have removable pads in the top.  I have put a pad inside of the smaller side but it tends to move around when I am swimming. I am thinking of cutting a slit on the inside of the top and see if it will stay put if it is between the material. I just ordered two more outfits this week and cannot wait for them to arrive!

The best time to wear these leggies is ALL THE TIME

I’m a scuba instructor + mermaid instructor trainer and having fun, comfy, and well made water apparel is a big plus. These leggies are soft and vibrant and will help you slip into your wetsuit, tail, or sport them without either!

Not to mention all the good that Waterlust does with their brand. Way to go!
I’m 200 lb, 5’7 (mostly legs!), and bought the XXL. They are long enough for my legs, fit in all the right places, and have…. Wait for it…. Pockets.


10/10 get them. They make me SO HAPPY.

I’m ready! I’m ready! I’m ready!

Love my Sponge Bob!

This is my 5th pair of leggings that I use when I go diving. They fit well. I am 5'7" and weight 134 pounds but still need a legendary size. They fit comfortably and protect my skin from the sun! My favorite part is that they come from plastic bottles as I despise single serve plastics.
