Bounce houses are one of the most popular additions to kids' parties, school events, festivals, and backyard celebrations. They’re fun, colorful, and give children hours of entertainment. But when dark clouds gather or water-based play is part of the plan, many people wonder: can a bounce house get wet? The short answer is yes—but with important precautions. Not all bounce houses are created equal, and knowing how water affects their structure, material, and safety is essential for proper use and long-term care.

In this comprehensive guide, we’ll explain everything you need to know about using bounce houses in wet conditions. From understanding the different types of inflatables to safety considerations and drying techniques, we’ll help you make smart choices that keep everyone safe and your bounce house in good shape.

1. The Two Types of Bounce Houses: Wet vs. Dry

Before we get into the details, it’s important to understand that not all bounce houses are designed to handle moisture the same way. There are dry-only units and wet/dry combo units, each built with different materials and structures.

Dry Bounce Houses are the standard inflatables commonly used at indoor events, backyard parties, and school functions. These are not designed to be intentionally exposed to water. The seams, floor, and inner linings can absorb moisture, which can lead to mold, mildew, and structural weakening over time.

Wet or Water-Compatible Bounce Houses, often called combo units, are made with water-resistant or waterproof materials, similar to those used in inflatable water slides. They feature sealed seams, drainage outlets, and non-slip surfaces. These are the only bounce houses that are safe to use with sprinklers, water hoses, or under light rain.

If you plan to incorporate water into your event or anticipate rain, you must rent or purchase a wet-rated inflatable. Otherwise, exposing a dry-only bounce house to water can result in damage and safety risks.

2. Can You Use a Bounce House in the Rain?

The question of whether a bounce house can be used in the rain depends on both the type of unit and the weather conditions.

For light rain, wet-rated bounce houses can often still be used safely, especially if they’re supervised closely and placed on a suitable surface. However, use should be stopped immediately if the rain becomes heavy or if thunder and lightning are present.

Dry-only bounce houses should never be used in the rain, even if it’s just a drizzle. Rainwater can seep into the seams and interior layers, causing not only damage to the unit but also making the floor slippery and unsafe for children.

Most rental companies will cancel bookings or delay setups during wet weather for this reason. Some will offer tarps or covers to protect the inflatable until the weather clears, but active use in the rain is strongly discouraged for non-waterproof units.

3. Water and Electricity: A Dangerous Mix

Another reason to be cautious about water around bounce houses is the use of electrical blowers. All bounce houses, regardless of type, require constant airflow from an electric blower to stay inflated. That blower is plugged into an outlet and usually positioned close to the unit.

If water enters the blower or extension cord, it can create a serious electrocution hazard. That’s why most inflatable safety guidelines recommend shutting down the bounce house immediately during rainfall or when water threatens the electrical components.

Always elevate blowers on crates or waterproof platforms to reduce the risk of splash damage. Use ground fault circuit interrupter (GFCI) outlets to prevent injury if a short circuit occurs.

4. Wet Play: What to Watch Out For

Even when using a water-safe bounce house, adding water changes the dynamics of play. Wet surfaces become slippery, and children can slide, fall, or collide more easily. While this can be fun in a water slide setting, it increases the risk of minor injuries like bumps, scrapes, or bruises.

To improve safety, consider these precautions:

• Limit the number of children at once to reduce crowding.

• Ensure all users remove shoes, jewelry, and glasses before entering.

• Instruct kids to slide feet first and avoid climbing on the walls.

• Assign an adult supervisor to monitor activity at all times.

These simple steps help reduce the risk of accidents, especially when water play is involved.

5. How to Dry a Wet Bounce House

If your bounce house does get wet—either from rain or water play—proper drying is essential. Storing it while still damp will lead to mold, mildew, foul odors, and even structural damage. Here’s how to dry your inflatable correctly:

• Keep it inflated: After the fun is over, leave the bounce house inflated so air can circulate through it.

• Towel off excess water: Use dry towels or absorbent cloths to wipe down all visible water on the surface, especially inside corners and seams.

• Allow it to air dry: Leave the bounce house in the sun for a few hours. The natural heat and airflow help evaporate remaining moisture.

• Check hidden areas: Moisture often lingers in folds, tunnels, or stitched edges. Use fans or even a leaf blower on a low setting to dry these parts.

• Inspect and roll for storage: Once fully dry, deflate and roll it up carefully. Make sure no water remains trapped inside, especially in the floor or walls.

A bounce house that’s stored wet even once can develop mildew stains that are nearly impossible to remove. Drying thoroughly is non-negotiable.

6. Storage and Maintenance After Getting Wet

Once dry, proper storage is the next critical step. Always store your bounce house:

• In a dry, indoor location away from moisture or pests

• Inside a breathable storage bag, not sealed plastic

• Off the ground if possible, to avoid accidental flooding or rodents

Inspect the bounce house before storing it. Look for mold spots, damage, or loose seams. If you notice anything unusual, clean and repair it immediately.

Use mild soap and warm water (not harsh chemicals) to clean any stains or grime left behind after water use. Rinse thoroughly and dry again before rolling up.

7. What If It Rains During an Event?

• If you're hosting an event and it starts to rain, don’t panic—but act quickly.

• Shut off water play immediately, and have children exit the bounce house.

• If it's a wet-compatible unit, monitor for pooling water and keep the blower dry.

• If the unit is not water-safe, turn off the blower, unplug it, and cover the equipment with waterproof tarps.

• Wait until the rain stops, then thoroughly dry the bounce house before allowing children to re-enter.

• Planning ahead with a rain policy or contingency plan is always wise, especially for outdoor events.

8. The Impact of Water on Bounce House Lifespan

Using water safely won't ruin a bounce house—if it’s designed for it—but frequent misuse or poor drying will shorten its lifespan. Exposure to moisture wears out the material faster, causes odors, and weakens the seams.

To preserve your inflatable investment:

• Only use water with wet-rated bounce houses.

• Clean and dry it after every use.

• Store it in a dry place with good ventilation.

For rental businesses, following these practices is essential for maintaining customer satisfaction and protecting your assets.

9. Renting vs. Owning: What to Ask

If you're renting a bounce house and plan to use it near water, ask the rental company:

• Is the unit rated for wet use?

• Can water be added safely?

• What is the rain policy?

• Will the company provide tarps or waterproof blowers?

• What are the drying requirements before pickup?

• Clear communication with the rental provider helps avoid damage fees and keeps everyone safe.

If you're buying your own bounce house, look for models specifically labeled wet/dry combo, and confirm that they come with non-slip floors, water drainage features, and waterproof materials.

Conclusion: Bounce Houses and Water Can Mix—With Care

So, can a bounce house get wet? Yes—but only the right kind and only when used responsibly. Wet/dry bounce houses are made for water use, while dry-only models are not. Water adds fun but also increases the need for careful supervision, drying, and maintenance.

Understanding these differences ensures that kids can enjoy safe, splashy fun while you protect your equipment investment. Whether you're renting for a party or running a rental business, being informed about bounce house safety and water use makes a big difference in the quality of your event.

With the right setup, the right inflatable, and a little attention to drying, a wet bounce house can offer just as much fun as a dry one—without any of the risks.
