A natural swimming pool costs $100,000 on average, with most homeowners spending between $75,000 and $150,000 depending on size, materials, and site conditions.1,2 Fixr prices a defined 30 x 20 ft concrete-lined build with stairs and a small deck at $70,000.3 Expect $50 to $100 per square foot.1,2 Prices below are national averages*.
*National averages, not local quotes. Angi and HomeAdvisor figures are from 2026 guides; Fixr figures are from a guide updated August 2022. Your price depends on the total footprint (swim zone plus regeneration zone), materials, and add-ons.

What the sources say
| Source | Headline figures | Notes |
|---|---|---|
| Angi (updated Jul 2026) | $100,000 average; most spend $75,000 – $150,000; $50 – $100 per sq. ft. | Labor $8,000 – $10,000 or more; permits $250 – $2,000 |
| HomeAdvisor (updated Jun 2026) | Same average, range, and per-sq.-ft. rate; prose describes a wider span from $25,000 | Corporate sibling of Angi – matching figures alone don’t establish independent corroboration |
| Fixr (updated Aug 2022) | $70,000 average for a 30 x 20 ft concrete-lined build with stairs and a small deck; range $60,000 – $80,000; low $50,000; high $100,000 | Labor $27,000 – $38,000; per-sq.-ft. material rates identical to Angi/HomeAdvisor |
Angi and HomeAdvisor publish the same average, range, per-square-foot rate, and material tables; they are corporate siblings, so matching figures alone don’t establish independent corroboration. Fixr’s $70,000 average is separately published, and the pages state no shared sourcing. Each average carries a different stated scope, so treat them as three labeled figures rather than one confirmed number.
Cost by size (Angi, 2026)
| Total pool size | Swimming area | Cost range |
|---|---|---|
| 500 sq. ft. | 50 – 350 sq. ft. | $25,000 – $50,000 |
| 1,000 sq. ft. | 100 – 700 sq. ft. | $50,000 – $100,000 |
| 1,400 sq. ft. | 170 – 1,330 sq. ft. | $75,000 – $125,000 |
| 3,250 sq. ft. | 900 – 1,800 sq. ft. | $125,000 – $150,000 |
Total size includes the regeneration zone, not just the swim area. Angi states 50% to 70% of the water is typically swimming area, with the rest dedicated to purification.1
Cost by material per square foot (materials only)
| Material | Cost range per sq. ft. | Average per sq. ft. |
|---|---|---|
| Liner | $0.25 – $1.20 | $0.72 |
| Clay | $0.50 – $1.50 | $1.00 |
| Gravel | $1 – $2 | $1.50 |
| Concrete | $55 – $70 | $62.50 |
| Fiberglass | $100 – $113 | $106.50 |
All three publishers print identical per-square-foot material rates.1,2,3 Angi and HomeAdvisor are corporate siblings; with Fixr, the pages state no shared sourcing. Gravel is used in the regeneration zone rather than the swim area.
Materials for a 600 sq. ft. pool (HomeAdvisor, 2026)
| Material | Materials cost (600 sq. ft.) |
|---|---|
| Liner | $150 – $720 |
| Bentonite clay | $300 – $900 |
| Concrete | $33,000 – $42,000 |
HomeAdvisor derives these examples from its per-square-foot rates at a stated 600 sq. ft. size.2
Material and equipment totals
| Item | Cost | Source |
|---|---|---|
| All materials, ground-up build | $30,000 – $49,000 | Angi (2026) |
| Materials, machinery, and excavation | $33,000 – $42,000 | Fixr (2022) |
| Pump and hardware | $300 – $1,200 | Angi/HomeAdvisor (2026) |
| Skimmer | $10 – $100 | Angi (2026) |
| Pool sand | $15 – $30 per ton | Angi/HomeAdvisor (2026) |
| River rocks | $35 – $800 per ton | Angi (2026) |
The two totals carry different stated scopes – materials only versus materials plus machinery and excavation – and are presented as published, not reconciled.
Labor
| Source | Labor figure |
|---|---|
| Angi/HomeAdvisor (2026) | $8,000 – $10,000 or more of the total; HomeAdvisor adds landscapers at $50 – $100 per hour and excavation contractors at $100 – $250 per hour |
| Fixr (2022) | $27,000 – $38,000; Fixr pairs this with $33,000 – $42,000 for materials, machinery, and excavation to reach its $60,000 – $80,000 average range |
The publishers state different labor totals; both figures are presented as published, with no stated basis for reconciling them.
Permits
Building permits for a natural pool cost $250 to $2,000, depending on location.1,2 Requirements vary locally, so confirm with your local authority before budgeting.
Converting an existing pool (Angi, 2026)
Converting a traditional pool to a natural pool can cost as much as or more than building new, because the footprint and shape usually change. Removing the old pool averages $6,000, and fresh excavation runs $8 to $25 per cubic yard, partly offset by the existing hole.1
Heating (Angi, 2026)
| Heater type | Cost |
|---|---|
| Solar (materials and labor) | $4,500 – $9,500 |
| Gas or propane | $1,500 – $6,000 |
| Heat pump | $2,500 – $7,500 |
Add-ons and features
| Feature | Cost | Source |
|---|---|---|
| Waterfall | $250 – $15,000 | Angi/HomeAdvisor (2026) |
| Waterfall, natural rock style | about $2,000 | HomeAdvisor (2026) |
| Waterfall | about $1,500 | Fixr (2022) |
| Lighting | $450 – $1,200 | Angi/HomeAdvisor (2026); Fixr (2022) |
| Retaining wall | $20 – $100 per sq. ft. | Angi/HomeAdvisor (2026) |
| Retaining wall | $20 – $25 per sq. ft. | Fixr (2022) |
| Pool fence | $1,100 – $12,000 | Angi (2026) |
| Pool slide | $1,000 – $15,000 | Angi (2026) |
| Pool deck | $3,000 – $12,000 | Angi (2026) |
| Aquatic plants | $10 – $100 per plant | Angi (2026) |
| Pool enclosure | $12,000 average | Angi (2026) |
| Hot tub | $2,000 – $35,000 | Angi (2026) |
Angi states add-ons can push a build from $75,000 to over $175,000, depending on pool size and features.1
Ongoing costs
Monthly maintenance for a natural pool costs $150 to $260.1,2 No chemical purchases are needed; Angi notes the remaining running costs are the pump and any heater, plus occasional pump servicing.1
How a natural pool works
The pool splits into a swimming zone and a shallower regeneration zone filled with crushed gravel and aquatic plants; a pump circulates water between them and the plants and gravel filter it. Angi states 50% to 70% of the water is swimming area,1 while Fixr describes the two zones as roughly equal in size.3
