Combo Units Rentals in Baltimore, Maryland, and the DMV Area

What is a combo unit, and how is it different from a regular bounce house?

A combo unit combines the classic fun of a bounce house with additional features like slides, climbing walls, basketball hoops, or obstacle elements—all in one inflatable! This makes them perfect for kids who want more variety during their party. In Baltimore, Maryland, and the DMV area, our combo units are extra popular for birthdays, school events, block parties, and festivals.

How many children can play in a combo unit at the same time?

Most combo units safely accommodate 6-10 children at a time, depending on their size and the age of the kids. Each inflatable has its own capacity guidelines, which our delivery team reviews with you during setup. If you have a large group, consider renting multiple units for maximum fun and safety!

What are the age requirements for combo unit rentals?

Our combo units are designed for children ages 2-14. Adult supervision is required at all times. If you’re planning for toddlers or have a wide age range, let us know—we can help you pick the best units for your group and suggest options like toddler units for younger siblings.

Which party themes do your combo units cover?

Bouncy Rentals offers a huge variety of themed combo units, including princesses, pirates, unicorns, Minecraft, Disney, football, Halloween, and more! Whether your party is Moana, dinosaurs, or outer space, you’ll find something to match on our Combo Units page.

Can combo units be used with water?

Several of our combo units are specifically designed for wet or dry use (like the Unicorn Wet & Dry Combo, Dolphin Wet and Dry Combo, and Hawaii Wet & Dry Combo). These are perfect for hot summer days in Baltimore or the DMV! If you want to add water fun, just look for our “Wet & Dry” options under Combo Units or filter your search during booking.

How long is the rental period for combo units?

What’s included in a combo unit rental?

All full-service rentals include delivery, professional setup, safety briefing, and takedown. The combo unit will arrive clean and ready for fun. For pickups, you’ll receive instructions for setup and cleaning, plus all necessary equipment (blower, stakes, extension cords). Browse our combo units for details.

What surfaces can combo units be set up on?

Combo units work best on flat, grassy areas but can also be set up on concrete, asphalt, or indoors. For water combos, grass is required for safety. Please clear the area of rocks, sticks, and debris prior to delivery. If you need help deciding, our team can advise during booking.

How much space do I need for a combo unit?

Most combo units need an area of at least 18x18 ft, but larger models may require 20x22 ft or more. Always allow for at least 2 feet of clearance on all sides for safe setup and access. Check individual product details on the Combo Units page or ask our team for exact space requirements.

Does the combo unit need power? What if I’m hosting at a park?

Yes, every combo unit requires a standard 120V household outlet within 50–75 feet of setup. For park events or locations without power, we rent generators. Be sure to check with your local Baltimore or DMV-area park for permit and power requirements. We’re happy to help coordinate!
