How Much Does a 12x12 Concrete Slab Cost With Labor?
Published August 11, 2026 · Concrete Pros of Nashville
A 12x12 slab is 144 square feet. At typical U.S. residential installed pricing of roughly $6–$12 per square foot for a standard broom-finished slab, that puts a basic 12x12 pad somewhere around $850–$1,750 — more for a stamped or decorative finish, thicker reinforced sections, or a site that needs significant excavation or hauling.
What a 12x12 slab is usually for
A 12x12 pour is a common size for a small patio, a shed or accessory-structure pad, a single-car parking pad, or an AC/generator equipment pad. The right thickness and reinforcement depend heavily on which of those it is — a patio and a structural equipment pad aren't built the same way even at the same footprint.
What's in the price
An installed price bundles several things: the concrete material itself, excavation and base preparation (compacted gravel base, typically 4+ inches), forming, reinforcement (wire mesh or rebar depending on use), the pour and finish, and cleanup. Material alone is a small fraction of the total on a job this size — site prep and labor usually make up more of the cost than the concrete itself.
What pushes the price up or down
A few things move a 12x12 slab's price more than anything else:
- Site access — can a truck and equipment reach the pour location, or does material need to be wheelbarrowed a long distance
- Excavation needs — removing an old slab, tree roots, or significant grade correction adds real cost
- Finish — plain broom finish is the baseline; stamped or exposed-aggregate finishes cost meaningfully more
- Thickness and reinforcement — a load-bearing pad (equipment, parking) typically needs more than a basic patio
Getting an accurate number
Because so much of the cost is site-specific, a phone quote for '12x12 slab' is really just a rough starting point. A written estimate after an actual site visit is the only way to know what your project costs — see our stamped concrete and structural concrete pages if you already know which direction you're leaning.
