At Monsterball, we have water slides in different sizes and styles, from smaller options for younger children to larger slides for parties with plenty of room. Before you book, it’s worth looking beyond the photos and thinking about how the slide will work at your party.
Here’s what to consider when choosing water slide hire in Perth for your child’s birthday.
1. Choose a Slide That Suits the Children’s Ages
Start with the children who will actually be using the slide. A water slide that looks exciting to older kids may be too challenging for younger guests, so check the recommended age range and safety requirements before choosing.For younger children, our Lil Splash water slide is one option to explore. If your party includes a mix of ages, tell our team about the group so we can help you compare suitable attractions.
It’s also worth considering whether children are comfortable climbing steps, waiting for their turn and following instructions. Choosing an appropriate water slide makes it easier to organise the activity around your guests.
2. Measure Your Backyard Before Booking
One of the easiest mistakes to make is measuring only the patch of grass where you imagine the slide will sit. The inflatable itself may need additional space for setup, access and safe use.Before choosing a slide, check:
- The length and width of your available area.
- The height clearance above the setup location.
- Whether the ground is suitable and reasonably level.
- Whether our crew can access the area with the equipment.
- Whether fences, trees, garden beds or outdoor furniture will get in the way.
If you’re unsure whether your yard is suitable, send us the measurements and tell us about the access. We can help you check the requirements for the slide you’re considering.
3. Think About How Many Children Will Be at the Party
Your guest list can help you decide which slide makes sense.For a small birthday party, a single-lane slide may be enough. If you’re inviting a larger group, a suitable dual-lane attraction could give children another way to enjoy the activity.
For example, our Fantastic Surf water slide has two lanes and an approximate capacity of 80 people per hour. Actual use will depend on how the attraction is operated and how quickly children take their turns.
Remember that capacity figures are guides, not a reason to rush children through the activity. Allow time for breaks, instructions and adult supervision, and follow the product’s safety requirements.
4. Check Water, Power and Setup Requirements
Water slides need more preparation than an ordinary party game. Before booking, make sure your venue has the right facilities for the attraction.Our team handles delivery, setup and pack-down. We can also explain what you need to have available at the venue before the party begins.
If you’re hosting the party at a park or hired venue rather than at home, check the site’s rules about water use, power access and inflatable installations before confirming your booking.
5. Set a Budget That Works for Your Party
The cost of water slide hire depends on the attraction and hire duration. Our current prices include the DNA Single Lane Water Slide from $490 + GST for three hours, while other slides have different starting prices.You don’t need to choose the largest slide to make the party enjoyable. Start with your budget, the available space and the ages of the children, then compare the options that suit those needs.
When requesting a quote, share your party date, address and preferred hire period. We can confirm availability and any applicable delivery charges for your location.
6. Plan for Safety and Supervision
Before the party, make sure an adult is responsible for supervising the activity and that children understand the rules for using the slide.Follow the instructions provided for your chosen attraction, including participant limits, safe entry and exit, and any age or height restrictions. Children should take turns as directed rather than crowding the slide or landing area.
Setup and anchoring requirements also matter. Depending on the surface, the inflatable may need to be pegged down or secured using suitable weights. Our crew will set up the equipment according to the applicable requirements.
Supervision arrangements vary between products. Some slides can be self-supervised with appropriate guidance, while others require an operator. Check the individual product page before booking so you know what is needed.
7. Have a Backup Plan for the Weather
A water slide is often a popular choice for a warm-weather birthday, but Perth weather can still affect outdoor plans.Check the forecast as your party approaches and think about where children can take a break out of direct sun. Keep drinking water available and plan other birthday activities for when children need a rest.
If rain is forecast, contact us as early as possible to discuss your options. Our published product pages include a rain-rescheduling policy with conditions, including 24 hours’ notice, so check the applicable terms for your booking.
