Are you looking for a unique and exciting way to celebrate your child’s birthday? Consider throwing a kids water battle birthday party! With water balloons, water guns, and lots of laughter, this party idea is sure to make a splash. This was the perfect theme for my son’s late summer birthday and here’s a step-by-step guide on how to plan an epic and fun water battle birthday party for your little one:
Step 1: Choose a Suitable Venue
The first thing to consider when planning a water battle birthday party is the venue. If you have a spacious backyard, it can be the perfect spot for the party. Alternatively, you can look for local parks or public spaces that allow water play. Just make sure to check if any permits or permissions are required. If you’re not using your own home make sure you have access to a lot of water for refilling stations!

Step 2: Send Out Invitations
Once you’ve secured the venue, it’s time to send out invitations. Get creative and design invitations that reflect the theme of the party. Include important details such as the date, time, location, and any specific instructions for the guests (e.g., bringing a towel or wearing a swimsuit). I also love using websites like paperless post and evite to send out my invitations rather than sending out paper invites!
Step 3: Plan Water Battle Games and Activities
To keep the kids entertained throughout the party, plan a variety of water battle games and activities. Here are some popular options:
- Water Balloon Toss: Pair up the kids and have them toss water balloons to each other. The pair that successfully catches the balloon without it bursting wins. We used these awesome reusable water balloons that way we didn’t have broken water balloons all over our yard!
- Water Gun Tag: One person is it and they have a water sprayer, and when they tag (spray someone) they drop the sprayer and the new person gets it.
- Water Elimination: Give everyone a water sprayer, one person starts as it, if you get sprayed you become it and this continues until the last person is out there unsprayed.
- Water Limbo: Set up a sprinkler or hose and play a water version of the classic limbo game. The kids will have a blast trying to shimmy under the water stream without getting wet.
- Sponge Relay Race: Create a relay race where teams have to pass a soaked sponge from one end to the other using only their hands. The team that finishes first wins.

Step 4: Party Decorations
To enhance the party atmosphere, decorate the venue with water-themed decorations. Hang up colorful beach towels, string up water balloons, and use water-inspired tablecloths and plates. Don’t forget to keep some towels handy for the kids to dry off between activities. I also put up caution tape to make it seem like a battle zone. I created these party signs feel free to download them and use them yourself!




Step 5: Create a Refill Station
When having an epic water battle you need to make sure you create refill stations. For our party we used a blow up kids pool full of water. If you don’t have one of these you can place multiple storage containers with water around your space. The good part about having the multiple containers is that when they are battling they aren’t all congregating in one space. Since we had the one pool we had to make a rule that you couldn’t spray someone at the refill station you had to step away before spraying.

Step 6: Provide Water Accessories
To ensure everyone can fully participate in the water battle, provide water accessories for the guests. This could include water guns, water balloons, buckets, and sponges. We provided all of our guests with water sprayers (they were from Target and no longer available). We also provided all of our guests with sun glasses to protect their eyes from the spray but you could also do goggles. And instead of asking guests to bring their own towels you can provide them as a gift.

Step 7: Hydration and Snacks
With all the running and splashing around, it’s important to keep the kids hydrated and energized. Set up a station with cool refreshments like infused water, juice boxes, and popsicles. You can also offer light snacks like fruits, sandwiches, and snacks that are easy to grab between water battles. We tried to keep the snacks on theme and had Goldfish, Pirate Booty, Gatorade and Gushers fruit snacks. Instead of doing a cake or cupcakes we also did personalized ice cream sundae station.

Step 8: Party Favors
As the party comes to an end, send the kids off with fun and water-themed party favors. Consider small water guns, water balloons, sunglasses, towels or personalized water bottles. Like I said earlier we went with water guns and sunglasses. These little tokens will remind them of the fantastic day they had at the water battle birthday party.
Step 9: Event Extras
There are some things I wish I could have done for our event but my space isn’t conducive to. One big thing I wish I could I could have had is a blow up waterslide. Instead I was able to have a slip and slide since our back yard is on a hill. It’s just some little fun extras that aren’t necessary but are fun all the same!
By following these steps, you’ll be able to plan an unforgettable water battle birthday party for your child and their friends, just like we did. Get ready for an amazing day filled with laughter, wet surprises, and memories that will last a lifetime!
Note: Make sure to consider the age of the kids and their swimming capabilities when organizing water-based activities. Adult supervision is essential throughout the party to ensure everyone’s safety.
Happy planning and have a splashing good time!
