Why We Ditched Traditional Bath Toys for Lego Duplo — And Haven’t Looked Back

ByAndrea

Let’s be real—traditional bath toys get gross so fast. Moldy squirters, slimy animals, water-stained boats… no thanks. I was tired of constantly tossing toys and searching for something new to keep bath time fun.

Then we discovered Lego Duplo, and my kids haven’t looked back.

Yep, we’re talking the same interlocking blocks your kids already love—but in the bath!

Why Lego Duplo Is Perfect for Bath Time

  • They float!
    Even when built into big, wild creations. I asked my oldest to make something cool to show off for the blog and he made a full-on house—with stacked blocks, a roof, and everything. And guess what? It still floated!
  • All plastic, no metal.
    That means no screws, no rusty parts, and no hidden mold traps. Everything is safe to get wet and easy to rinse.
  • Creative play doesn’t stop at the water’s edge.
    Instead of dumping and scooping, now my kids build castles, towers, boats, and “bath cities” that float and float.
  • No mystery slime or gross water inside.
    Lego Duplo blocks don’t trap water like squirty toys, so cleanup is a breeze.
  • Super easy to clean.
    Just rinse them off after bath time and let them dry!

Bonus Perks

  • Keeps kids in the bath longer
    (Which = peace and quiet or time to finally clean the sink.)
  • Fun for all ages
    My toddler loves stacking and smashing them, while my big kids get more creative with their builds.
  • Travel-friendly
    Toss a few in a bag, and you’ve got instant entertainment for hotel baths and trips.

Mom Hack You’ll Love

Before bath time, I give each kid a small plastic bin and tell them to build their boat. Once they’re done, we “launch” them into the tub and watch what floats—and what tips over.

It’s like a mini science experiment every night. What floats? What sinks? Why did your house survive while your brother’s fell apart?

Final Thoughts

I’ll never go back to typical bath toys again.

Lego Duplo has turned bath time into a creative, mess-free, mold-free adventure. They float, they clean up easily, and my kids are totally obsessed.

If you’re looking for something new to keep your kids engaged and your tub toy basket clean—this is it.
