In-Ground Trampoline Cost: Pricing, Installation, and Is It Worth It?

It is tempting to look at an in-ground trampoline and think, “How hard can it be? Dig a hole and drop it in.” The hole, as it turns out, is where things get interesting.

Once you factor in the trampoline, excavation, drainage, retaining walls, and landscaping, most in-ground trampoline projects come out somewhere between $4,000 and $9,000. We will walk through every piece of that number, so you can decide if a sunken setup fits your yard.

How Much Does an In-Ground Trampoline Cost?

A professionally installed in-ground trampoline costs roughly $4,000 to $9,000, with most Ohio and Kentucky backyards landing between $5,000 and $7,000. The trampoline accounts for about half of that. Other factors influencing the costs include size, material quality, and installation complexity.

Here is how a typical project splits out.

Ranges are estimates. Your final number depends on soil, site access, and grading.

Our North units run from $2,399 for the 12ft x 8ft rectangle to $3,399 for the 17ft x 12ft, with the 14ft round at $2,499. A bigger frame means a bigger hole, so size drives both halves of the bill. Our trampoline sizes guide covers how to choose according to your available space.

How Much Does an In-Ground Trampoline Cost to Install?

The trampoline installation cost for an in-ground setup usually adds $2,000 to $5,000 on top of the unit. That covers the dig, drainage, and labor to level and secure the frame.

Excavation drives the quotes most. Sandy, easy-to-dig ground keeps in-ground trampoline costs near the low end, while clay, rock, or a sloped yard pushes them up. Standard digging runs $2.50 to $15 per cubic yard, but most contractors carry a $500 to $800 job minimum, and rock that needs a jackhammer jumps to $50 to $200 per cubic yard. Southwest Ohio clay is heavy but diggable; buried limestone is the expensive surprise.

The retaining wall holds the pit open and varies the most. Block walls run $15 to $40 per square foot installed, and a 14ft round pit has roughly 44 feet of wall to build. Proper drainage prevents water buildup under the trampoline but adds $10 to $35 per linear foot for a run out to daylight or a dry well. You may also need a municipal permit, which can cost $50 to $200.

For a side-by-side with above-ground pricing, see how much a trampoline costs. An above-ground model of the same size runs about half as much once installation is included, so the cost of an inground trampoline really comes down to whether the investment makes sense for your backyard.

Professional Installation Process for an In-Ground Trampoline

When planning a new trampoline installation, call 811 at least a few business days in advance and have utility locators mark the location of underground gas, water, and electrical lines. Excavating a three-foot pit into an unmarked service line may cause a gas leak or cut a power cord, which is genuinely dangerous.

Sizing

First, mark the trampoline’s footprint. The excavation should be wider at the top than at the bottom, creating a shallow bowl rather than a flat-bottomed box. This shape allows the jumping mat to extend downward beneath the jumper without making contact with the soil.

Excavation

Once the area is marked, excavation can begin. A 14-foot round pit typically requires approximately 10 to 14 cubic yards of soil to be removed. You'll need to redistribute that material elsewhere on the property or haul it away, which may add a few hundred dollars to the project cost. Site access is also an important consideration.

If equipment can pass through a side gate, a mini excavator can significantly reduce excavation time compared with manual digging or a wheelbarrow.

Retaining walls

After excavation, install a retaining wall around the pit perimeter. This step is important for maintaining the shape and stability of the excavation. Without adequate support, exposed soil can erode or slump into the pit, particularly after heavy rain. A properly installed retaining wall helps prevent soil erosion around the trampoline opening.

Water drainage

Address drainage before installing the trampoline frame. A gravel base is typically placed at the bottom of the pit, along with a perforated drainage pipe that directs water toward a lower area of the yard or a dry well. A basic drainage system may cost a few hundred dollars on a straightforward site, while more complex drainage requirements may cost several thousand dollars if water must be redirected over a greater distance or site conditions are challenging.

Frame installation

Finally, the team positions, levels, and anchors the frame before installing the mat and safety pads. The surrounding turf or landscaping is then repaired as needed. Most installs take one to three days, which is the main driver behind trampoline installation cost on the labor line.

Can You Just Bury a Regular Trampoline?

No, and this is the single most expensive mistake in backyard trampoline projects. An above-ground trampoline dropped into a hole will bounce badly, rust quickly and sit unusable within a couple of seasons.

Three things go wrong. Air has nowhere to escape when a jumper lands, so the mat hits a cushion of trapped air and loses its bounce. Water collects in a pit built without drainage and rots the mat and springs from below.

The third is the frame itself. Galvanized above-ground frames are built for open air, not constant soil contact, so corrosion sets in at the joints.

Purpose-built in-ground trampolines solve all three in the design. The frame is treated for ground contact, the pad system is vented to move air, and the manufacturer specifies the pit shape the mat needs. This is also why a sunken trampoline is sold as a complete system rather than as a frame you improvise around.

What Are the Downsides of In-Ground Trampolines?

In-ground trampolines look cleaner and sit lower, but they come with real trade-offs.

• Higher total cost. You pay twice, once for the trampoline and once for the groundwork, and the installation is usually the larger number.
• Permanent structure. Moving a sunken frame means reversing the entire excavation, so this is a ten-year decision about your yard layout.
• Drainage issues. Leaves, mulch and grass clippings work into the pit and can block the drain, and poor water management can increase the risk of damage around the pit or pooling. If possible, add a trampoline cover over the mat between uses to keep most of that debris out.
• Awkward net access. The enclosure poles sit at ground level, making entry and exit less natural than stepping up through a gate.
• Mowing and repairs. A hard edge prevents the mower deck from riding over it, and reaching springs or a mat means working at ground level rather than underneath the frame.
• Space suitability. High water tables, shallow bedrock, and steep grades can drive costs up or rule the project out, and nearby concrete, brick, or pool decking can complicate excavation and drainage routing.

Is an In-Ground Trampoline Worth It?

Yes, an in-ground trampoline can be a great investment for families who want a long-term backyard feature for their kids that integrates better with the landscaping.

Fall height is a major consideration. If a jumper goes over the edge of an in-ground trampoline, they step or fall onto the lawn rather than from the height of a raised frame. It also has no ladder for kids to climb unsupervised.

Sightlines are another advantage. A flush trampoline does not block the view across the yard from the kitchen window, making it easier to keep an eye on kids while they play. Its low profile may also work better in neighborhoods with HOA restrictions on taller backyard structures. For model-level detail, see our roundup of the safest trampolines for kids.

The frame is also less exposed to wind, and you never spend a Saturday moving it to mow underneath. When it's sitting unused, a trampoline cover keeps sun and debris off the mat.

Skip the in-ground build if you rent, plan to move within a few years, have a yard that holds water, or want the flexibility to reposition the trampoline later. In those situations, a small rebounder or an above-ground model might be a better fit.
