Best Combo Units for Party Rental Businesses
Combo units combine a bounce house with a slide (and sometimes a basketball hoop or climbing wall) into a single inflatable. They're the highest-revenue inflatables in most rental fleets because you can charge 30 to 50% more than a standard bounce house.
Overview
A combo unit is the smartest second purchase for most rental operators. By combining bouncing, sliding, and climbing into one unit, you offer more value to customers, which means higher rental prices. Most operators charge $250 to $450 for a combo vs. $150 to $300 for a standard bounce house.
Combos come in two main categories: dry combos (year-round use) and wet/dry combos (can be used as a water slide in summer). We strongly recommend wet/dry combos for your first purchase because they double your seasonal revenue potential.
The trade-off is size and weight. Combos are typically larger (15 to 20 ft long) and heavier (250 to 400 lbs), so you'll likely need a trailer and a helper for setup. But the ROI makes it worth it, a $3,000 combo unit can generate $8,000 to $15,000 per season.
Typical Rental Pricing
$250 - $450
Dry rental. Add $50 to $100 for wet/water slide use. Premium themed combos can command $400+.

What to Look For
- Wet/dry compatibility, doubles your seasonal revenue potential
- Commercial PVC or lightweight commercial vinyl (15 oz+ minimum)
- Reinforced slide lanes with high sidewalls for safety
- Removable pool attachment for wet use (should drain easily)
- Multiple activities: bounce + slide + climbing wall or basketball hoop
- Weight under 300 lbs if you're a solo operator with one helper
- Warranty covering both the bounce area and slide seams (these are the failure points)
What to Avoid
- Dry-only combos for your first unit, wet/dry gives you flexibility
- Units over 400 lbs unless you have a dedicated crew and box truck
- Combos without reinforced slide stitching, slides take the most abuse
- Single-activity combos (just bounce + slide) when 4-in-1 units cost the same
- Themed units in niche colors unless you've confirmed local demand
- Manufacturers who charge extra for pool attachments, these should be included
