Buyers typically pay for a kidney shaped pool based on shell material, size, site prep, and finishing. The cost overview below tracks the exact price factors and common per-unit ranges for this popular shape. The first 100 words summarize budget drivers and the potential cost range you can expect.
Assumptions: Midwest or nationwide pricing with standard materials, typical lot access, and normal decking and equipment package.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Overall kidney pool installed | $35,000 | $60,000 | $90,000 | Includes shell, basic finish, pump, filtration, and standard decking |
| Concrete/gunite shell (in-ground) | $40,000 | $70,000 | $100,000 | Labor-intensive; larger sizes increase cost per sq ft |
| Vinyl liner shell | $25,000 | $40,000 | $60,000 | Lower upfront, liner replacement every 7–15 years |
| Fiberglass shell | $40,000 | $55,000 | $70,000 | Factory-fitted; quick install |
| Decking and coping | $6,000 | $15,000 | $40,000 | Material and size dependent |
| Permits and inspections | $500 | $2,500 | $6,000 | Region and code-dependent |
| Electrical and plumbing upgrades | $1,000 | $4,000 | $10,000 | Includes rough-in and wiring to equipment pad |
Formula: labor hours × hourly rate
Material Choices That Drive Kidney Pool Price
The pool shell type and finish are the largest cost levers. A concrete shell with plaster or aggregate finish yields higher long-term durability but adds upfront labor and material costs. Vinyl liners offer the lowest initial price but require eventual liner replacement. Fiberglass provides a mid-range option with a faster install timeline. Material choice affects yearly maintenance and replacement windows, not just initial price.
Size, Depth, And Shape Precisely Change The Quote
Smaller kidney pools under 12×20 feet cost toward the lower end, while larger layouts with sun shelves or deeper sections push estimates higher. Per-square-foot costs vary by shell type and access, typically ranging from $20 to $60 per sq ft for the shell alone.
Regional Pricing Variations You Should Expect
Urban coastal markets and regions with labor shortages tend to run higher, while rural areas or markets with competitive builders can lower the price. Typical regional deltas reach ±15% to ±30% from the national average. Plan for a higher budget if extensive grading or tree removal is needed.
Labor Time And Crew Size Impact The Total
Gunite kidneys require more on-site time than prefab shells, often translating to 2–4 weeks of work including prep, pouring, curing, and finishing. A small crew may lower labor hours but extend duration. Estimated labor costs commonly represent 20%–40% of the total.
Site Prep, Grading, And Access Complications
Shallow bedrock, slope, or tree roots add to prep expenses. Utilities relocation or trenching for drain and electrical lines can add several thousand dollars. Unseen subsurface conditions are a frequent cause of budget overruns.
Permits, Codes, And Inspection Fees
Many jurisdictions require building permits, safety barriers, and pool-specific inspections. Fees vary by jurisdiction but commonly range from $500 to $3,000. Noncompliance can cause delays and rework costs.
Equipment Packages And Ongoing Operating Costs
Energy-efficient pumps, variable-speed options, and smart controls influence both upfront price and long-term operating costs. A basic pump and filter set may run $1,000–$3,000, while advanced systems can push to $5,000 or more. Annual energy and chemical costs should be included in a 5–10 year budget view.
Maintenance, Repairs, And Replacement Cycles
Concrete shells typically require resurfacing every 10–20 years and may need tile or coping replacement sooner. Vinyl liners typically last 7–12 years, fiberglass shells 20–30 years with occasional gel coat repairs. Factor in replacement cycles when calculating 10-year ownership costs.
Smart Budgeting: How To Reduce Kidney Pool Price
Choosing a simpler decking plan, standard finish, and avoiding premium features can trim costs. Flexible scheduling, bundling with landscaping, and deciding between repair or full replacement at the first sign of wear can prevent premium upgrades. Careful scoping keeps the project within budget.
Estimate Scenarios: Three Realistic Quotes For A 12×28 Foot Kidney Pool
Example A uses a vinyl liner shell with basic decking; Example B uses a gunite shell with mid-range plaster and composite decking; Example C uses a fiberglass shell with upgraded lighting and a simple coping. Prices include shell, basic equipment, and standard permits where applicable.
| Scenario | Shell Type | Size | Decking | Estimated Total | Notes |
|---|---|---|---|---|---|
| Quote A | Vinyl liner | 12×28 ft | Basic concrete | $38,000–$52,000 | Lower upfront; liner replacement needed later |
| Quote B | Gunite | 12×28 ft | Composite decking | $70,000–$95,000 | Durable finish; more labor hours |
| Quote C | Fiberglass | 12×28 ft | Frameless glass tile | $58,000–$78,000 | Faster install; tile upgrade adds cost |
