What is the typical cost of a 20x20 concrete patio ?
For a 400-square-foot patio in Tucson, Tucson Superior Concrete uses a typical installed range of $3,500 to $8,000, with slab thickness, finish, and site conditions driving the final number. Understanding what a quote includes helps prevent a material-only figure from being mistaken for the total project cost.
Quick Summary
- A standard broom-finished 20x20 patio with a 4-inch slab typically costs $3,500 to $6,500 installed in Tucson.
- A 4-inch slab needs roughly 4.94 cubic yards of concrete, while a 6-inch slab needs 7.4 cubic yards.
- Stamped concrete typically ranges from $6,000 to $11,200; colored concrete ranges from $4,800 to $8,000 for the same footprint.
- Ready-mix concrete runs $125 to $165 per cubic yard, while excavation, base preparation, and reinforcement can add $800 to $1,800.
Three Numbers That Shape the Budget
Thickness and Finish
Plain broom-finished concrete runs $8 to $16 per square foot installed. Most patios use 4 inches, while hot tubs, grill islands, pergolas, and other heavy loads may call for 5 to 6 inches with added rebar.
Itemized Quote Check
Compare demolition, excavation, compacted gravel base, formwork, reinforcement, concrete placement, finishing, sealing, and cleanup. A low quote may cover concrete alone rather than the complete installed scope.
What to Inspect Before Comparing Quotes
20x20 Patio Footprint and Site Access
A measured 20-by-20-foot, 400-square-foot patio layout with the crew's access path, existing grade, drainage direction, and any caliche excavation area. These conditions affect equipment use, hauling, and base preparation.
4-Inch vs 6-Inch Slab Cross-Section
Both slab depths over a compacted gravel base, including the additional concrete and reinforcement used for heavier loads. The cross-section makes the quantity and cost difference easier to understand.
Broom, Stamped, and Colored Finish Samples
The texture and edge detail of plain broom, stamped, and colored concrete side by side. Finish selection changes labor, coloring, release-agent, and sealing costs.
20x20 Patio Cost Snapshot
Standard 4-Inch Patio
The square-foot calculation produces $3,200 to $6,400 before decorative upgrades. A 4-inch slab uses 4.94 cubic yards, usually ordered as 5 yards, with raw concrete costing about $625 to $825.
Reinforced 6-Inch Patio
A 6-inch patio uses 7.4 cubic yards, typically ordered as 7.5 yards, and costs about $4,800 to $8,200 installed. The extra thickness can add $950 to $1,250 in material cost over the 4-inch option.
Decorative Finish Range
Finish upgrades range from no added charge for a basic broom texture to $4 to $8 per square foot for more involved options. Integral color or acid staining adds about $2 to $5 per square foot, while stamped work can bring the 400-square-foot total to $6,000 to $11,200.
Budgeting Mistake to Avoid
Do not compare a raw-concrete price with a complete installed bid. A do-it-yourself approach may also require $400 to $600 in mixer, form-lumber, and finishing-tool rentals before accounting for base compaction, reinforcement, or compliance with ACI 318 and ASTM C94 specifications.
Cost by Slab Type and Finish
| Patio Type | Thickness | Approximate Installed Cost for 400 Sq. Ft. |
|---|---|---|
| Basic broom finish | 4 inches | $3,500-$6,500 |
| Reinforced patio | 6 inches | $4,800-$8,200 |
| Stamped concrete | 4 inches | $6,000-$11,200 |
| Colored or integral tint | 4 inches | $4,800-$8,000 |
What 20x20 Patio Pricing Includes
A complete patio price can include demolition, excavation, spoil hauling, gravel base, formwork, rebar or wire mesh, ready-mix delivery, placement, finishing, curing, sealing, permits, and cleanup. Materials typically represent 35 to 45 percent of the total, labor represents 40 to 60 percent, and the remainder covers items such as disposal, permits, overhead, and sealing.
What Changes a 20x20 Patio Estimate
Excavation, hauling, and compacted-base work can run $700 to $2,000 as grade, drainage, site access, and caliche depth change; rebar, wire mesh, and gravel base can add another $600 to $1,200. Labor commonly runs $1,800 to $3,500 and accounts for 40 to 60 percent of the project across forming, pouring, screeding, floating, edging, and curing supervision. In Tucson, crews may schedule early-morning pours from June through August to limit rapid surface moisture loss, while slabs tied to drainage or structural additions may need permit and inspection review.
Common Follow-Up Questions
Concrete generally costs $1 to $3 less per square foot than pavers for the same footprint, although pavers allow easier spot repairs. A 2-inch slab is not enough for a residential patio; normal foot traffic calls for a minimum of 4 inches, with 5 to 6 inches considered for heavier fixed loads. Installation typically takes 2 to 4 days, followed by 5 to 7 days of curing before heavy use; sealing within the first month and again every 2 to 3 years helps protect the surface. For size comparisons, a 15x30 patio is 450 square feet and runs about $3,900 to $7,200 with a broom finish or $6,800 to $12,600 with decorative work, while a 12x12 patio is 144 square feet and runs about $1,300 to $2,600 for a basic finish.
