Expect total costs for a 20×40 gunite pool to fall in the mid-range when considering shell, plumbing, decking, and finishing. The key price drivers are shell size, finish quality, equipment package, site prep, and local labor rates. This article uses cost-focused figures in USD to help buyers plan a budget and compare quotes for a 20-by-40 gunite pool.
Assumptions: Midwest labor rates, standard 8-inch shell, standard plaster finish, mid-range equipment, and typical access.
20×40 Gunite Pool Total Cost Range
The complete project typically lands between $90,000 and $160,000 for a standard 20×40 gunite pool, with the finish and features shaping the spread. Most projects fall around $110,000-$135,000 before accessories, decking, and landscaping. Perimeter and depth variations push the price up or down.

|---|---|---|---|---|
| Shell (gunite) | $45,000 | $60,000 | $90,000 | 8-inch shell, basic contour |
| Finishes | $8,000 | $15,000 | $25,000 | plaster, aggregate, or quartz |
| Plumbing & Electrical | $10,000 | $15,000 | $25,000 | lines, gas if needed, wiring |
| Equipment & Controls | $8,000 | $12,000 | $20,000 | Pump, filter, heater, automation |
| Decking & Coping | $12,000 | $25,000 | $40,000 | concrete, pavers, or stone |
| Permits & Inspections | $2,000 | $4,000 | $8,000 | local fees vary |
| Site Work & Excavation | $5,000 | $12,000 | $20,000 | grading, drainage |
| Delivery/Haul & Disposal | $2,000 | $4,000 | $8,000 | soil and debris |
Formula: total = shell + finishes + plumbing/equipment + decking + permits + site work + delivery
What Makes Up a Gunite Pool Quote
Major cost components include the gunite shell, interior finish, mechanical package, deck materials, and site-related expenses. A typical 20×40 configuration uses an 8-inch shell, mid-range plaster, standard equipment, and modest decking.
| Cost Component | Typical Range | What This Covers | Notes |
|---|---|---|---|
| Gunite shell | $45,000-$60,000 | Concrete shell and shaping | Impact of depth profile |
| Interior finish | $8,000-$25,000 | Plaster, aggregate, or quartz | Color and texture affect price |
| Mechanical package | $8,000-$20,000 | Pump, filter, heater, controls | Smart vs basic controls add cost |
| Decking/Coping | $12,000-$40,000 | Concrete, stone, or pavers | Size and material drive price |
| Site work | $5,000-$20,000 | Grading, drainage, excavation | Access and soil conditions matter |
| Permits/inspections | $2,000-$8,000 | Local compliance costs | Some regions require more scrutiny |
Variables That Strongly Move the Final Price
Two key drivers often shift bids for a 20×40 gunite pool: depth and finish choice. A deeper pool or a custom contour adds concrete volume and form-work time, while a premium plaster or quartz finish raises material costs and long-term maintenance expectations. Depth choices can swing $5,000-$15,000 in shell cost; finishes can add $4,000-$15,000 depending on pigment and texture.
Other numeric thresholds to watch: site access (tight lots add crane or portable equipment costs) and equipment tier (basic vs variable-speed pumps or full automation can add $3,000-$8,000).
Regional Price Variations You Should Expect
Coastal markets and regions with fewer qualified crews tend to push up bids, while areas with plentiful labor may run lower. On average, expect a regional delta of about 10% to 20% between the low-priced Midwest/South and higher-cost West Coast markets for a 20×40 gunite pool.
| Region | Typical Range | Notes |
|---|---|---|
| Midwest/South | $95,000-$140,000 | Strong competition, moderate costs |
| West Coast | $110,000-$170,000 | Higher labor and permitting |
| Northeast | $105,000-$155,000 | Material costs can edge higher |
Labor Inputs That Shape the Quote
Labor hours for a 20×40 gunite project depend on crew size, weather, and subtrades. A typical crew of 4–6 workers over several weeks yields a substantial portion of the cost. Labor can be $40-$90 per hour depending on region and crew skill, with total labor often $20,000-$40,000 in mid-range projects.
Popular Upgrades That Move the Price
Optional features such as a heater-only vs heat-pump, LED illumination, in-floor cleaning systems, and a resort-style spillover spa add-ons. A premium finish or automated controls can push the price by $6,000-$15,000 in many plans. Choosing premium lighting and automation typically raises total cost.
Permits, Inspections, And Code Costs
Permits vary by city and state. Expect a few thousand dollars in most jurisdictions, with higher fees where structural inspections or safety barriers are mandated. A thorough plan may include approval fees, plan reviews, and final inspections totaling $2,000-$8,000.
Decking, Coping, And Surrounding Hardscape
Deck materials and coping choices heavily influence the project’s final price. Concrete decks near $15-$25 per sq ft installed, while pavers can run $20-$40 per sq ft. For a 20×40 pool, decking could range from $12,000 to $40,000 depending on material and layout.
Maintenance And Long-Term Ownership Costs
Gunite pools require periodic plaster refresh, equipment service, and energy use for pumps and heaters. Annual upkeep often ranges from $1,000-$2,500, with major replaster refreshes every 8–15 years adding a similar order of magnitude to future budgets. Factor in potential seasonal repairs and chemical costs.
Ways To Reduce The Price Without Sacrificing Safety
Consider batching work to reduce mobilization fees, selecting standard finishes, opting for mid-range equipment, and adjusting decking to a simpler design. Proper planning and timing can trim 5%–15% from the base price by avoiding rush scheduling and over-customization. Scope control and sensible material choices are key.
Quote Comparisons: Real-World Benchmarks
When evaluating proposals, compare shell depth, finish type, equipment tier, and decking scope. A mid-range 20×40 gunite pool with quartz finish and standard automation often lands around $120,000-$135,000, with premium features pushing higher and simpler builds closer to $100,000.
