Homeowners typically pay a broad range for river rock by the yard depending on rock size, delivery distance, and installation needs. Main cost drivers include rock type, supplier pricing, and whether professional installation is included or performed by the buyer.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| River Rock (Materials) cubic yard | $60 | $120 | $240 | Sizes vary; decorative 1–2″ typically on the lower end, larger 3–6″ higher |
| Delivery / Fuel Surcharge | $50 | $100 | $250 | Distance and fuel costs influence price |
| Installation (Labor) per 100 sq ft | $300 | $600 | $1,200 | Includes base prep and edging; harder when edging or irrigation is involved |
| Base prep & Edging (Materials) | $20 | $60 | $150 | Includes landscape fabric and edging material |
| Terrain / Site Prep Fees | $0 | $40 | $120 | Steep slopes or fetch-heavy areas may add cost |
Assumptions: region, rock size, depth of cover, and whether installation is performed by a pro or DIY.
Overview Of Costs
River rock cost per yard includes materials, delivery, and optional installation. Typical installed price ranges from $310 to $1,590 for 100 sq ft of cover at 2 inches deep, with per-yard material costs spanning roughly $60 to $240 and labor contributing a sizeable portion when professional installation is chosen. The largest cost variable is the labor rate and whether edging, weed barrier, and soil prep are required.

What Drives Price
Rock size and color are primary drivers: smaller, standard 1–2″ river rocks are cheaper than larger 3–6″ stones. Assumptions: typical residential landscape beds, uniform depth of 2 inches.
Cost Drivers By Region
Prices vary by region due to supply and transport. In the Northeast, typical installed costs trend higher due to delivery and materials. The Midwest often shows mid-range pricing, while the West can include higher hauling fees from rock yards farther away. Regional differences can produce a ±15% to ±35% swing from national averages.
Labor, Hours & Rates
Labor costs depend on crew size and time. A standard crew can cover 100 sq ft at 2 inches depth in 3–5 hours, translating to roughly $300–$600 in labor for basic installs. Longer runs, steeper terrain, or intricate edging raise the time and cost. Per-hour rates commonly range from $40 to $120 depending on local market and complexity.
Additional & Hidden Costs
Hidden costs may include weed barrier fabric, additional edging, landscape fabric staples, and disposal of existing materials. If drainage work or irrigation modifications are needed, expect incremental costs. Delivery surcharges and remote-site fees can add 20% or more to the material total in some markets.

Seasonality & Price Trends
Prices may fluctuate with supplier inventory and seasonal demand. Demand spikes in spring and early summer can raise delivery and material costs, while late summer or fall may yield softer pricing in some regions. Booking ahead can improve availability and pricing.
Local Market Variations
Regional differences can tilt total project costs by roughly ±20% depending on urban vs. suburban vs. rural markets. Urban areas often incur higher delivery fees but may access closer rock yards, while rural sites face longer travel distances and higher fuel charges.
