Hosting a party for 20 or more kids? You will likely need a larger inflatable or multiple units. Expect to pay $200-$500 for a single large unit or $350-$700 for two inflatables. Here is a full breakdown of what to expect.
Best Inflatable Options for 20+ Kids
For a group of 20 kids, a standard 13x13 bounce house will create long wait times. Here are better options:
- Large combo unit (20x20): $250-$400. Bouncing area plus a slide keeps more kids active at once.
- Obstacle course: $300-$500. High throughput — kids cycle through quickly, so everyone stays engaged.
- Two standard bounce houses: $200-$450 total. Many vendors offer 10-20% off the second unit.
- Bounce house + water slide: $350-$600 total. Variety keeps different age groups happy.

Tips for Renting Bounce Houses for Large Groups
- Book early: Large units are limited inventory. Book 3-4 weeks ahead, especially for weekends.
- Add an attendant: For 20+ kids, an attendant ($75-$150) helps manage safety and flow.
- Separate by age: If your group mixes toddlers and older kids, consider two different-sized units.
- Ask about multi-unit discounts: Most vendors offer 10-20% off when you rent 2+ inflatables.
- Check your space: Large combos need 20x20+ feet. Obstacle courses need 40x15+ feet. Measure your yard before booking.
