About Us
Watermelon Ball began as a simple idea: create a plaything that encourages active, social time in the water while lasting season after season. Founded by swimmers, designers, and parents, we’ve spent years developing a water-weighted ball that behaves differently from ordinary inflatables—sinking, hovering, and responding to underwater motion so games become more dynamic. Our small-team roots mean we test every design in real pools, lakes, and beaches and learn directly from families and swim coaches. Quality matters: we use thick, UV-resistant materials, reinforced seams, and components built to withstand chlorine, salt, and rough play. We also prioritize safe, non-toxic materials and packaging that minimizes waste. Over time we’ve grown into a trusted name among backyard hosts, swim instructors, and dog owners who want toys that actually last. Beyond products, we focus on clear, honest communication—real-world instructions, durable accessories like filling needles and adapters, and responsive support when customers need help. We balance performance with responsibility, keeping designs simple, repairable, and long-lived. Our commitment is to bring more movement, connection, and outdoor joy to your moments in the water, backed by practical experience and durability you can trust.

Reviews from our clients
My small pool needed something different—this ball sinks and hovers, making diving and underwater catching way more fun. My son charges after it like a little otter; we toss and watch how it spins and curves underwater. The rubber is thick and shows no wear after a few accidental tosses out of the pool. It’s hefty enough to feel solid, so supervise younger kids until they understand it’s water-weighted, not a balloon.
We used this at a weekend party and adults loved it—tossing it for huge splashes and testing underwater throws. The material feels solid and thick, so I expect it to last despite heavy use. The built-in light turns on when the ball moves, so nighttime play is surprisingly bright without frequent battery swaps; note there is a small plastic tab over the battery that must be removed first. I learned that adding more water and less air makes it heavier and creates bigger splashes. Setup is straightforward and it’s safe for mixed-age groups.
This toy kept a group of kids entertained for hours—great for games like keep-away, pool soccer, or solo diving practice. Fill it completely with water—any trapped air makes it float instead of hovering. The material seems robust and holes are unlikely; filling is straightforward with a needle and adapter. Best with three or more players but still fun solo.

I wasn’t sure at first, but it’s a total win—this ball sinks and hovers so underwater games feel new and active. Setup was easy: hose adapter and needles in the box and once full it weighed about 14.5 lbs. The tough PVC stands up to rough play and pool chemicals; the cute pattern makes it easy to spot beneath the surface. It encourages teamwork, movement, and even simple drills for teens. Don’t expect a beach-ball float—it’s meant to stay submerged. Overall, great value and dependable for family use.
We bought ours in 2021 and it’s still going strong despite daily pool exposure, Florida sun, and two very rough kids. Some surface markings faded over time, but the ball kept its shape and seams through throws onto concrete and rough play. The durability surprised me—chemical exposure hasn’t caused leaks. I’d buy it again for long-term family use.
Our dog can’t get enough of this toy—he chews, tugs, and carries it daily and it still looks good. The nylon straps make grabbing and tugging easy, and it works great in the yard or pool. It floats and dries quickly, so it’s useful in all weather. The paw-print design caught his attention immediately. It’s durable, versatile, and has become a staple of playtime—also handy for quick, wet fetch sessions at the lake.
