Biodesign, or natural swimming pools, offer a cost profile that differs from traditional inground concrete or liner pools. The main cost drivers include site work, filtration system design, planting phases, and ongoing maintenance considerations. This article outlines typical costs, price ranges, and practical budget tips for U.S. buyers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Biodesign Pool (Total) | $60,000 | $90,000 | $150,000 | Includes design, excavation, plant beds, and filtration system |
| Inground Concrete Pool (Total) | $50,000 | $85,000 | $150,000 | Includes shell, plumbing, misc. site work |
| Per-Square-Foot (Biodesign) | $180 | $260 | $450 | Assumes standard 15,000–18,000 gallons |
| Per-Square-Foot (Inground Concrete) | $150 | $230 | $400 | Varies by finish and rebar grade |
| Maintenance Annual (Biodesign) | $1,000 | $2,000 | $4,000 | Filtration media, plant care, seasonal cleanups |
| Maintenance Annual (Inground) | $800 | $1,600 | $3,000 | Chemical balance, filtration, equipment checks |

Overview Of Costs
Biodesign pools typically cost more upfront than basic vinyl liners but can be cheaper than premium concrete when factoring long-term maintenance. A typical project spans design, excavation, biofilter beds, planting, and a naturalized circulation system. The total project ranges reflect site complexity and regional labor rates. Expect per-unit ranges to vary with pool size and planting density.
Inground concrete pools offer durability and design flexibility but carry higher labor and material costs, especially with custom shapes, finishes, or gunite applications. Per-unit pricing often scales with basin size, reinforcement, and deck integration.
Cost Breakdown
| Category | Biodesign | Inground Concrete | Notes |
|---|---|---|---|
| Materials | $25,000–$60,000 | $25,000–$70,000 | Soil, filtration media, plants, pump, plumbing |
| Labor | $20,000–$40,000 | $25,000–$55,000 | Site prep, trenching, planting beds |
| Equipment | $5,000–$8,000 | $8,000–$15,000 | Biofilter components vs concrete pool gear |
| Permits | $1,000–$4,000 | $1,000–$6,000 | Local rules vary; may require inspections |
| Delivery/Disposal | $1,000–$5,000 | $1,000–$5,000 | Soil, rock, spoilage management |
| Warranty & Contingency | $2,000–$6,000 | $2,000–$6,000 | Contingency for unforeseen work |

What Drives Price
Biodesign price drivers include plant selection, biofiltration tube routing, and the size of the natural filtration swale. SEER-like considerations are less relevant; instead, plant maturity, species hardness, and water balance requirements influence ongoing costs. A larger planting bed and more diverse flora increase both initial and maintenance expenses.
Inground concrete price drivers center on shell shape complexity, finish choices (pebble, plaster, or tile), deck integration, and plumbing runs. Longer runs or irregular shapes raise labor time and material waste, pushing up costs. Regional labor rates can swing totals by 10–25%.
Ways To Save
Budget tips include aligning pool size with yard boundaries to minimize grading, choosing standard shapes over custom geometry, and selecting mid-range filtration for both systems. Scheduling work in off-peak seasons can reduce labor costs, and bundling landscaping with the pool project may reduce separate site prep charges.
Regional Price Differences
Prices vary across regions due to labor markets, climate, and permitting complexity. In the Northeast, higher labor and permit costs can add 10–20% versus the national average. The Southeast often features builder competition that can push price ranges downward by 5–15%. The Midwest may fall near the national midpoint but with seasonal scheduling impacts that shift availability and cost by ±10%.
Labor, Hours & Rates
Labor hours for biodesign projects depend on planting density and swale complexity, typically more than a standard concrete shell for similar sizes. Concrete pools demand precision carpentry and plumbing, with crews ranging from small specialty teams to larger multi-trade crews. Regional wage differences commonly create ±10–25% variation in total labor costs.
Real-World Pricing Examples
Basic Biodesign: 14,000 gallons, simple planting, standard biofilter; 3–4 weeks; Total $70,000; $5,000 materials, $28,000 labor, $5,000 equipment, $2,000 permits, $2,000 disposal; $/sq ft ≈ $180.
Mid-Range Inground Concrete: 16,000 gallons, basic finish, standard deck; 6–8 weeks; Total $95,000; $40,000 materials, $35,000 labor, $12,000 equipment, $5,000 permits, $3,000 disposal; $/sq ft ≈ $230.
Premium Biodesign with mature plantings and high-diversity swales: 18,000 gallons; 5–8 weeks; Total $140,000; $70,000 materials, $50,000 labor, $12,000 equipment, $6,000 permits, $2,000 disposal; $/sq ft ≈ $260.
Assumptions: region, specs, labor hours.
Maintenance & Ownership Costs
Biodesign pools incur ongoing plant care and seasonal biofilter maintenance, which can average $1,000–$4,000 annually after the first year. Inground concrete pools tend to have steadier chemical management and equipment service at $800–$3,000 per year, depending on climate and usage. Over a 5-year horizon, total ownership costs reflect both maintenance needs and potential equipment upgrades.
Seasonality & Price Trends
Prices can drift with demand swings in spring and early summer. Some markets offer off-season incentives, especially for larger packages that include landscaping or outdoor living spaces. Early budgeting with a regional contractor helps lock in favorable material and labor rates.
