In-ground trampolines are becoming a popular choice for families who want to add a fun activity to their backyard. By installing a trampoline below ground level, you can create a safer jumping experience that also looks great with your outdoor landscape. This guide will cover everything you need to know about in-ground trampolines
What are In-Ground Trampolines?
An in-ground trampoline is installed below ground level so that the jumping surface sits flush with the yard. The frame and springs are placed into a dug pit and enclosed by a protective deck and padding prior to being covered with soil and grass on top. This allows jumpers easy access to the trampoline without having to climb up onto it. The surrounding ground also acts as an added safety barrier compared to above ground trampolines.
Benefits of In-Ground Trampolines
Installing a trampoline below ground provides many advantages:
Safer Jumping
With an in-ground trampoline, there is no elevated risk of falling off the edges onto hard ground. The protective enclosure sits below ground level, preventing accidental tumbles. Jumpers also have soft grass or padding to land on if they lose balance.
Blends Into Landscaping
Sink the trampoline into your backyard landscape seamlessly when not in use. The grass camouflages the jump space, complementing gardens and lawn areas. No need for unsightly ladders or tall safety nets in the yard.
Space Saving
In-ground trampoline frames sit nearly flush with the grass, with only the jumping mat slightly raised. They have a minimal footprint in your landscape compared to large above ground trampolines. Great for smaller yards!
Accessibility
The sunken jumping platform allows all ages to easily climb on for their bouncing fun. No need to ascend ladders which can deter less able-bodied jumpers. Entry is made safer and simpler for all.
Aesthetic Appeal
Maintain your backyard’s aesthetic appeal by installing a trampoline below ground level. Avoid an bulky above ground eyesore and keep your landscape looking good from every angle.
What Size Options Are Available?
In-ground trampolines come in a variety of shape and size options to fit your family’s needs:
Round
Excellent bounce for single jumpers. Range from 7 feet in diameter for toddlers up to 16 feet for athletic training.
Rectangular
Rectangular trampolines allow for multiple simultaneous jumpers. Sizes start at about 6 x 10 feet and go up to 9 x 15 feet for backyard models.
Oval
Oval trampolines offer both long elasticity with supportive rebound. Average dimensions are 10 x 16 feet.
When determining trampoline size, consider not just the pit dimensions but the total width including protective padding and framework. Make sure you have adequate yard space to accommodate excavation needs.
What Are the Parts of an In-Ground Trampoline?
Below ground trampolines consist of several components working together to facilitate safe jumping:
Frame: The heavy-duty steel or galvanized metal frame fits into the in-ground pit. Shock-absorbing springs connect the outer frame to the bounce mat.
Springs: Attached to the frame, the trampoline springs stretch out as jumpers land on the mat. This gives that classic trampoline bounce everyone loves by providing uplifting force.
Jumping Mat: The middle mat area is made of tightly woven polypropylene mesh fabric for both durability and bounce. UV resistance prevents sun damage.
Safety Padding: Thick foam encases the whole frame, springs, edges and sides. This protects jumpers from any hard surfaces both above and below ground.
Enclosure Netting: Netting around the inside perimeter prevents anyone from falling off the trampoline edges. Pole foam and entrance clips keep you safely bouncing.
Underground Pit: A large hole is dug around the jumping area, allowing the whole trampoline unit to sit nearly flush with lawn level upon installation.
What Size Pit Do You Need?
When installing an in-ground trampoline, you first need to dig a adequately sized pit before setting up the unit. Calculate your pit size and depth as follows:
Diameter
For round trampolines, add at least 2 feet beyond the frame diameter for installation needs. Rectangular trampolines require an additional 2 feet width and length.
Depth
Construct your pit at least 1 foot deeper than the trampoline frame height. Most backyard frames stand about 2-3 feet high above ground so plan for at least a 3-4 foot deep hole.
Material Disposal
Remember that excavating a giant hole in your yard will generate lots of soil, rock and debris to remove. Include disposal plans in your overall project scope.
Properly measuring and digging your in-ground hole takes careful planning but prevents problems down the road! Recruit professional help as needed for optimal safety.
What Are Some Safety Considerations?
While in-ground trampoline installation allows for safer bouncing than above ground options, always keep these precautions in mind:
Proper Enclosure Use
The protective netting should fully enclose the interior at all times. Secure the entryway clips whenever the trampoline is occupied to prevent falls.
Avoid Hard Surfaces
Clear away any rocks or hard materials around the sunken trampoline perimeter that could cause injury if landed on. Install thick padding.
Supervise Children
Actively watch young jumpers at all times. Help them learn proper landing techniques and enforce rules. Limit number of occupants based on age and size.
Maintain Components
Inspect the springs, mat, netting and padding frequently. Repair any loose parts, holes or unsafe areas immediately before further bouncing.
Taking key safety steps goes a long way in preventing trampoline-related injuries! Now let’s explore everything that goes into installing your underground jump zone.
How Much Does an In-Ground Trampoline Cost?
Prices for in-ground trampolines vary based on size, shape, and included accessories but expect to invest around $3,000 to $6,000 for a complete backyard setup. Here’s a breakdown of costs:
Equipment
The trampoline unit itself ranges from $1,500 up to $4,000 depending on configuration preferences. Popular options like integrated basketball hoops also impact pricing.
Excavation
Hiring an external company to dig the requisite pit adds approximately $1,500 to $2,000. Rates depend on yard composition and pit dimensions.
Installation
Professionally installing the trampoline equipment inside the dug pit averages $500 for labor unless you DIY. Complex builds benefit from expert assembly.
Additional expenses may apply for site permits, waste removal fees, landscaping restoration and more. Plan your total budget accordingly!
What Kind of Maintenance Is Required?
While in-ground installation provides added jumping equipment protection from weather, some regular maintenance helps ensure optimum safety:
Drainage: Check drainage holes after heavy rains to confirm no standing water collecting around trampoline parts. Prevent rust and deterioration.
Landscaping: Mow grass above ground level routinely just like the rest of your lawn. Trim vegetation contacting netting. Rejuvenate bare areas as needed.
Weathering: Inspect equipment at least monthly for UV damage, tears or soil accumulation. Repair or replace components accordingly before further bouncing.
Off-Season Care: Consider retractable covering systems and anchor weights to shield your sunken trampoline from harsh winter winds and snow. Secure all netting.
Following the manufacturer’s care recommendations makes maintaining your underground bounce system much easier year-round!

| Ground Cover Options | Mulch, pea gravel and rubber surfacing all safely cushion the sunken trampoline space when not in bouncing action. Match existing materials. |
| Low-Profile Plantings | Vegetative groundcovers, subtle wildflowers and dwarfed shrubs integrate well next to partially submerged trampoline enclosures at lawn level. |
| Flowering Vines | For more vertical interest over the dug pit, install poles or fencing for flowering vines like clematis and honeysuckle to climb. Just don’t obstruct jumping areas. |
| Water Features | Consider incorporating a small in-ground fountain or rock-lined pond near your trampoline space. The soothing sounds make outdoor time more relaxing and harmonious. |
Get creative with how your new below ground recreation feature coexists amongst the rest of your landscape!
How Much Yard Space Do You Need?
Ensure you have adequate open area in your backyard for your dream in-ground trampoline setup. Space needs factor both below and above ground considerations:
- Pit Opening: Allow at least 2 feet clearance beyond frame diameter for the underground cavity itself. Remember the deeper you dig, the wider across the hole spans.
- Surface Buffer Zone: Overground, allow ample run-off and non-jumping space around trampoline perimeter. Many manufacturers recommend at least 6 feet on all sides.
- Vertical Clearance: Consider trees, power lines or roof overhangs above proposed install site. While sunk below lawn level, some parts may obstruct safe use if items loom overhead in jump zone.
- Access Pathway: Include room for an walking entry path to your trampoline away from hazards like pools or play structures. Stairs work well sloping down into sunken cavity space.
When planning trampoline placement, focus on safety first not just aesthetics! Your family will enjoy years of healthy bouncing activity with the right site prep.
Popular In-Ground Trampoline Variations to Consider
While traditional circular recreational trampolines work well sunk below ground, consider these popular variations too:
Oval Trampolines: The elongated oval shape allows multiple jumpers with excellent bounce across the length. Great for families! Look for over 10 feet wide.
Basketball Hoops: Integrate a basketball hoop right on the protective netting enclosure for added bouncing fun – no hard surfaces nearby to worry about!
Pit Trampolines: Extra deep in-ground pits with trampoline floors let you literally jump right into the ground below. Access ladders or stairs lead down into the sunken cavity.
Exercise Trampolines: For fitness training, look for durable rectangular or square Olympic trampoline models made of tight supportive bands without noisy distracting springs.
From recreational play to sports training, get the whole family bouncing with an in-ground trampoline customized to your needs!
