Practical Quotes Snapshot: Three Real-World Scenarios
Estimate ranges illustrate how scope differs in common setups. The examples below assume a 200 square foot bed with a standard 2- to 3-inch rock depth, accessible site, and curbside delivery.
| Scenario | Rock Type | Depth | Labor | Delivery | Total Range |
|---|---|---|---|---|---|
| Basic Bed | Standard River Rock | 2.5 in | $300 | $120 | $1,100–$1,400 |
| Color Accent | Premium Color River Rock | 3 in | $420 | $180 | $1,700–$2,100 |
| Smoothed Finish | Smoothed River Rock | 2 in | $360 | $150 | $1,400–$1,800 |
Estimate formula: Total = (Material cost per sq ft × area) + (Labor per sq ft × area) + Delivery + Base materials + Disposal. This approach helps compare bids that separate rock, base, and labor charges clearly. Assumptions: 200 sq ft bed, standard edging, no permit needs.
