Why Pool Work Fits Piece Rate
Pool construction is one of the most specialized corners of the construction world, and the two trades that lend themselves best to piece rate are gunite/shotcrete (the shell) and plaster (the finish). Both are measured in square feet, both require speed and skill in equal measure, and both have a natural deadline — the material sets, so the crew has to work efficiently or the quality suffers.
I'm Tyson Faulkner. I come from roofing, not pools, but I've spent time around pool contractors and the piece rate model is deeply embedded in this trade. Most pool shell and plaster crews have been working on a per-pool or per-square-foot basis for decades. The question isn't whether to pay piece rate — it's whether your rates are fair and competitive.
This guide covers real rate ranges for gunite, shotcrete, and pool plastering, what factors affect pricing, and how to build a structure that keeps experienced crews coming back.
Gunite and Shotcrete Shell Rates
Gunite (dry mix) and shotcrete (wet mix) are the two methods for shooting the pool shell. Both involve a nozzleman, a finisher, and typically 3 to 5 additional crew members operating the rig, handling hoses, and shaping walls.
Rate Ranges for Pool Shell
Standard residential pool (400-600 sq ft surface area):
- Gunite, standard depth (3.5' to 8'): $1,800 to $3,000 per pool
- Shotcrete, standard depth: $1,600 to $2,800 per pool
- Per square foot equivalent: $3.50 to $6.00 per square foot
Large residential or custom pools (600-1,000 sq ft):
- Gunite/shotcrete: $2,800 to $5,000 per pool
- Per square foot: $4.00 to $6.50 per square foot
Commercial pools (1,000+ sq ft):
- Per square foot: $4.50 to $7.50 per square foot
- These are often bid per project rather than piece rate due to complexity
Spa/hot tub additions:
- Attached spa: $800 to $1,500 per spa
- Standalone spa: $1,000 to $2,000 per spa
How Per-Pool vs. Per-Square-Foot Rates Work
Most gunite contractors price per pool for standard residential work because pool sizes within a market are fairly consistent. A "standard" pool in a given market might be 15' x 30' with a shallow end of 3.5' and a deep end of 8'. The crew knows what that looks like and how long it takes.
Per-square-foot pricing makes more sense when pool sizes vary widely, for commercial work, or when quoting custom designs where the surface area can range dramatically.
What a Gunite Crew Should Earn
A full gunite crew (nozzleman, finisher, plus 3-4 laborers) should shoot a standard residential pool in one day. Larger or complex pools may take 1.5 to 2 days.
For a 5-person crew earning $2,500 for a standard pool:
- Total crew earnings: $2,500
- Nozzleman (top rate, typically 25-30% of total): $625 to $750
- Finisher (20-25% of total): $500 to $625
- Laborers (splitting remaining): $375 to $460 each
The nozzleman and finisher are the skilled positions. Their rates reflect years of experience and the fact that they control quality. Laborers do the heavy lifting — moving hoses, mixing material, and shaping forms.

Factors That Push Gunite Rates Higher
Pool depth and shape. A simple rectangular pool with a consistent depth is the fastest to shoot. Freeform shapes, vanishing edges, raised walls, beach entries, and extreme depth (10'+) all add time and complexity. Custom shapes can add 25-50% over standard rates.
Elevation and access. Hillside pools where the gunite rig can't get close, pools with limited truck access, or pools requiring material to be pumped extra distance all slow production. Access difficulty can add 15-30% to the rate.
Wall height and thickness. Standard residential walls are 6 to 8 inches thick. Walls for commercial pools, retaining walls, or raised beam construction are thicker and taller. More material, more time.
Steel complexity. The gunite crew doesn't typically install rebar (that's a separate trade), but shooting around complex steel — waterfalls, baja shelves, swim-up bars — slows the application process significantly.
Weather. Gunite and shotcrete work is weather-sensitive. Wind affects material placement. Extreme heat causes faster setting, reducing working time. Cold weather requires additives and can affect cure quality. Some crews adjust rates seasonally.
Pool Plastering Rates
Pool plastering is the finish coat — the final interior surface that holds the water. It's applied by a specialized crew and must be done in one continuous application per pool. There's no stopping halfway. This makes it inherently suited to piece rate — the crew is motivated to work fast because the material has a limited working time.
Rate Ranges for Pool Plaster
Standard white plaster (marcite):
- Per square foot: $1.50 to $2.50 per square foot
- Per standard residential pool (400-600 sq ft): $700 to $1,300
Quartz aggregate (Diamond Brite, Hydrazzo):
- Per square foot: $2.00 to $3.50 per square foot
- Per standard pool: $1,000 to $2,000
Pebble finish (PebbleTec, PebbleFina):
- Per square foot: $2.50 to $4.50 per square foot
- Per standard pool: $1,300 to $2,500
Glass bead or tile finish:
- Per square foot: $3.50 to $6.00+ per square foot
- Per standard pool: $1,800 to $3,500+
Plaster Crew Earnings
A plaster crew typically consists of 4 to 8 people depending on pool size. The crew includes a lead plasterer, one or two trowelers, and multiple material runners.
For a standard quartz-finish pool at $1,500 per pool with a 6-person crew:
- Lead plasterer: $350 to $450 (highest rate)
- Trowelers (2): $225 to $300 each
- Material runners (3): $100 to $175 each
A plaster crew that stays busy should complete 1 to 2 pools per day. At 1.5 pools per day averaging $1,500 each, daily crew earnings are $2,250. Over a 5-day week, that's $11,250 in crew earnings.
What Drives Plaster Rates Higher
Finish material. White plaster is the cheapest and fastest to apply. Quartz takes slightly longer because the aggregate needs to be properly exposed. Pebble finishes require additional steps for exposing the pebble surface (acid wash or water exposure). Each step up in material adds 20-40% to the labor rate.
Pool size and shape. Small, rectangular pools are fastest. Large, freeform pools with lots of curves, steps, benches, and water features have significantly more surface area to trowel and more detailed work around features. Custom pools can take 50-100% longer than standard.
Condition of the shell. A well-prepared shell (properly cured gunite, clean surface, good bond coat) plastering goes smoothly. A shell with rough spots, form marks, or inadequate prep requires more material and more troweling time. The plaster crew shouldn't have to fix the gunite crew's problems — if they do, the rate should reflect it.
Time of year. In hot climates (Arizona, Florida, Texas), summer plastering requires working fast because the material sets quicker in heat. Some crews start before dawn to get more working time. Extreme heat can reduce the crew's working window and effective production.
Tile and Coping Rates
Pool tile and coping are often installed by a separate specialty crew. Waterline tile and coping cap the shell and provide the finished edge.
Waterline tile:
- Standard 6" waterline tile, per linear foot: $6.00 to $12.00
- Glass mosaic waterline tile: $10.00 to $18.00 per linear foot
Coping (cap stones):
- Standard paver coping, per linear foot: $5.00 to $9.00
- Natural stone coping (travertine, limestone): $7.00 to $14.00 per linear foot
- Cantilevered concrete coping: $4.00 to $8.00 per linear foot
A standard residential pool has approximately 70 to 100 linear feet of coping and waterline tile. At $8.00/LF for coping and $8.00/LF for tile, that's about $1,120 to $1,600 in combined labor per pool.
Setting Up a Pool Rate Card
| Work Type | Unit | Rate Range | Notes |
|---|---|---|---|
| Gunite, standard pool | per pool | $1,800-$3,000 | 400-600 sq ft |
| Gunite, large/custom | per sq ft | $4.00-$6.50 | Over 600 sq ft |
| Shotcrete, standard pool | per pool | $1,600-$2,800 | 400-600 sq ft |
| Attached spa shell | per spa | $800-$1,500 | Add-on |
| Plaster, white marcite | per pool | $700-$1,300 | Standard finish |
| Plaster, quartz aggregate | per pool | $1,000-$2,000 | Mid-range finish |
| Plaster, pebble finish | per pool | $1,300-$2,500 | Premium finish |
| Waterline tile | per LF | $6.00-$12.00 | Standard tile |
| Coping, paver | per LF | $5.00-$9.00 | Standard material |
| Coping, natural stone | per LF | $7.00-$14.00 | Premium material |
| Custom shape premium | per pool | +25-50% | Freeform, vanishing edge |
Share this with every crew before the job. The nozzleman should know the per-pool rate. The lead plasterer should know the finish-specific rate. Transparency prevents disputes.
Compliance Considerations
Hour Tracking
Pool construction crews often work dawn to dark during busy season. Track every hour. Per-pool pay doesn't exempt you from FLSA requirements. Read more in our article on tracking hours for piece rate workers.
Overtime
A gunite crew that shoots 6 pools in a 55-hour week earns piece rate for each pool, but you still owe overtime. Calculate the regular rate (total weekly earnings / total hours), then pay 0.5x that rate for every hour over 40. Our guide on overtime for piece rate workers covers the full calculation.
Crew Classification
Pool subcontracting is an area where worker misclassification is common. If your "subcontractor" crews use your equipment, follow your schedule, and work exclusively for you, they may legally be employees. Misclassification carries serious penalties. See our article on W-2 vs 1099 for piece work crews for guidance.
Safety
Gunite and shotcrete work involves high-pressure material application, confined space work (inside the pool shell), silica dust exposure, and heavy equipment operation. Cutting corners on safety because the crew is rushing to finish and get paid is a real risk with piece rate. Build safety time into your per-pool rate or pay safety tasks (PPE setup, dust control, confined space protocols) separately.
Regional Market Differences
Pool construction rates vary dramatically by region:
- Sun Belt dominance. Florida, Texas, Arizona, and California account for the majority of residential pool construction. High volume means more competition but also more established rate norms.
- Seasonal markets. In northern states (Ohio, Pennsylvania, New York), pool construction has a shorter season. Crews need to earn more per pool during the working months.
- Custom vs. production. Markets with mostly custom pools (resort areas, high-end neighborhoods) pay higher per-pool rates but have lower volume. Production pool markets (suburban Texas, Florida subdivisions) have lower per-pool rates but steady, high-volume work.
Reviewing Rates
Pool work rates should be reviewed annually, or whenever:
- Material costs shift. Plaster, quartz, and pebble material prices fluctuate. Labor rates should adjust with material difficulty, not material cost per se, but significant material changes often coincide with application differences.
- Crew turnover. If experienced nozzlemen or lead plasterers are leaving, your rates are below market. These are hard-to-replace skills.
- Quality issues. Plaster delamination, gunite voids, or uneven finishes may indicate crews rushing to hit production targets. Review the balance between speed and quality.
