12ft Lego Junior Wet/Dry Slide - The Toddler-Friendly Water Slide Built for the Youngest Party Guests
The 12ft Lego Junior Wet/Dry Slide is the only water slide in the Jump Around Party Rentals lineup with a minimum age of 2. Twelve feet tall, vibrant Lego brick design, wet or dry operation, and a compact 8-by-21-foot footprint that fits in backyards where even the smaller 16-foot slides cannot. It is built specifically for the ages-2-to-12 crowd, and it is the right answer for any birthday party where toddlers, preschoolers, and early elementary kids are the majority of the guest list. No child who shows up at the party gets sent to the sidelines because they are too young to ride.
It also solves a real problem at events that book a kids water slide rental with an age floor of 6 and up. Younger siblings who cannot ride the main slide get their own separate water attraction that is exactly their size and exactly their speed. At $245 per day it is the lowest individual slide price in the lineup and affordable as a companion rental alongside a larger slide or bounce house.
One standard 110V outlet, a garden hose for wet mode, and 23 feet of clear length. Book online or call (512) 294-2221 to confirm availability. Friday early delivery is often available at no extra charge for Saturday events.

Why the Lego Junior Wet/Dry Slide Delivers at Kids Birthday Parties
The Only Slide in the Lineup Open to 2-Year-Olds
Every other water slide in the Jump Around Party Rentals lineup has a minimum age of 3, 6, or higher. The Lego Junior starts at 2. That single difference makes it irreplaceable for birthday parties where the birthday child or their younger siblings are toddlers. A 2-year-old does not get left out of the water fun. A 3-year-old gets a slide that is appropriately sized for their height and confidence level rather than a tower built for older kids. Questions about which slide fits which age group? The team is easy to reach through the Jump Around Party Rentals contact page.
Lego-Themed Design - Already Decorated for a Kids Party
The vibrant Lego brick color scheme does the party decorating work on its own. Children ages 2 through 12 recognize the design immediately and the excitement that follows the moment the slide inflates is hard to replicate with a plain-colored alternative. For Lego-themed birthday parties the slide is a centerpiece attraction that matches the décor exactly. For non-themed parties it is simply a bright, exciting, recognizable design that appeals to every child in the age group.
Smallest Footprint in the Lineup - 8 Feet Wide and 21 Feet Long
At 8 feet wide and 21 feet long, the Lego Junior has the smallest setup footprint of any water slide in the lineup. Tower slides in the 16-foot class need 14-16 feet of width and 28-36 feet of length. The Lego Junior fits in that narrow side yard between the fence and the house, in a small rental property backyard, or in any space where nothing else in the lineup would work. That compact footprint also makes it easy to position alongside a bounce house or tables and chairs without dominating the entire yard layout.
Wet or Dry - Year-Round Fun From Summer to Fall
Connect a hose and the Lego Junior runs as a full wet slide with water flowing down the lane. Skip the hose for fall birthday parties, indoor gymnasium events, and cool-weather celebrations where a dry slide is the right call. The 12-foot height delivers real excitement for the 2-to-12 age group whether running wet or dry. At $245 per day it is also the most affordable slide rental in the lineup, making the wet-or-dry flexibility even more practical when event planning on a budget.
Events Where the Lego Junior Wet/Dry Slide Delivers
Toddler and Preschool Birthday Parties
Birthday party rentals where the birthday child is 2 to 5 years old get a slide built exactly for their age, size, and confidence level. Twelve feet is genuinely exciting for a toddler or preschooler. The Lego design generates immediate enthusiasm the moment it inflates. At $245 per day it is the most accessible water slide price in the lineup for families hosting their first big backyard party.
Companion Slide for Events With a 6-and-Up Main Slide
Events that book a Blue Crush, Purple Crush, or any 20-22ft slide with a 6-and-up age floor get the Lego Junior as a dedicated second water station for the younger guests. Families in Cedar Park water slide rentals and across the Greater Austin Metro add this alongside a bigger slide so no child is left watching from the sidelines. Jump Around Party Rentals delivers both in a single trip.
Lego-Themed Birthday Parties
Lego-themed birthday parties get a slide that matches the theme without sourcing a single additional decoration. The colorful Lego brick design on the inflatable is immediately recognizable and ties the whole party space together. For children ages 4 to 10 with Lego party themes, this slide is the centerpiece that makes every other decoration feel intentional. It runs wet for summer parties or dry for indoor and fall events equally well.
School and Church Events for Young Children
Pre-K and kindergarten school events, church nursery parties, and early childhood community events get a slide with an age floor that matches their demographic exactly. The 2-to-12 range covers every young child at the event. In dry mode the Lego Junior works for indoor gymnasium events and fall community celebrations without water concerns. The 8-foot width fits in tight venue setups where larger inflatables would not.

Frequently Asked Questions
How old does a child need to be to ride the lego junior water slide?
The Lego Junior Wet/Dry Slide is rated for ages 2 to 12. It is the only water slide in the Jump Around Party Rentals lineup with a minimum age of 2, making it the right choice for birthday parties that include toddlers and preschoolers. The upper limit of 12 means this slide is designed specifically for young children, not teenagers or adults.
Can the lego junior water slide run without water?
Yes. The Lego Junior runs wet with a garden hose connected for summer birthday parties and backyard events, or completely dry for fall parties, indoor gymnasium events, and cool-weather celebrations. Dry mode delivers the same 12-foot sliding experience without the water element. Let Jump Around Party Rentals know at booking which mode you plan to use so setup is confirmed correctly.
What yard space does the 12ft lego junior water slide require?
The Lego Junior requires 10 feet of width and 23 feet of clear length - the smallest setup footprint of any water slide in the lineup. Most 16-foot tower slides need 28-32 feet of length and 14-16 feet of width. The Lego Junior fits in yards where those larger options would not. Call (512) 294-2221 to confirm your specific space works before booking.
Can I pair the lego junior slide with a bigger slide at the same event?
Yes, and this is one of the most common reasons people book the Lego Junior. When the primary slide has a 6-and-up age floor, the Lego Junior serves the younger guests simultaneously at a separate station. Jump Around Party Rentals delivers both in a single trip. Call (512) 294-2221 or visit our party rental FAQ page for common multi-rental questions.
Is the lego junior water slide good for a lego-themed birthday party?
Yes. The vibrant Lego brick design matches a Lego party theme without any extra decoration needed. Children ages 2 to 12 recognize the colorful brick design immediately. It decorates and entertains at the same time. The 12-foot height is appropriate and exciting for the 4-through-10 age range where most Lego-themed birthday parties land.
What rental periods are available for the lego junior wet/dry slide?
The Lego Junior is available at day ($245), 8-hour ($269.50), overnight ($392), and 3-day ($514.50) rates. At $245 per day it is the most affordable water slide in the lineup. Overnight suits birthday sleepovers. The 3-day rate covers holiday weekends at one delivery fee. Friday early delivery for Saturday events is often available. Call (512) 294-2221 to book.
