Installing a saltwater pool costs $25,000 on average, with most homeowners paying $12,000 to $38,500 for a new in-ground build, according to Angi (updated October 2026)1. HomeAdvisor – corporate sibling publishing matching figures, which alone do not establish independent corroboration – reports the same $25,000 average and $12,000 to $38,500 range, against a $23,000 average for a chlorine pool (updated June 2026)2. Fixr, an unaffiliated publisher, prices a 15 x 30 foot vinyl in-ground family pool with a diving board at a $50,000 national average, within a $30,000 to $70,000 range – from $3,600 for an above-ground fiberglass pool to $100,000 for a concrete infinity-edge pool with an enclosure (updated January 2025)3. The averages carry different stated scopes, and no conclusion about the gap follows.
New build vs. conversion
Converting a chlorine pool to saltwater costs $500 to $2,500 at Angi and HomeAdvisor12, against Fixr's $600 to $2,500 – $600 to $1,200 for an above-ground pool and $1,200 to $2,500 for an in-ground pool3. For new construction, Fixr prices above-ground saltwater pools at $3,600 to $24,500 and in-ground pools at $41,500 to $112,5003, while Angi and HomeAdvisor's overall in-ground range is $12,000 to $38,50012; the publishers' in-ground figures diverge, and the pages state no shared sourcing.
Cost by pool size
Angi and HomeAdvisor share identical size figures (2026)12; Fixr's installed prices (2025) overlap on several sizes with different numbers3:
| Pool size | Angi/HomeAdvisor (2026) | Fixr installed (2025) |
|---|---|---|
| 10 x 16 ft | $15,000 – $26,000 | – |
| 10 x 20 ft | – | $15,000 – $25,000 |
| 12 x 20 ft | – | $18,000 – $30,000 |
| 10 x 30 ft | $24,000 – $42,000 | $22,500 – $37,500 |
| 12 x 24 ft | $27,000 – $50,000 | $21,600 – $36,000 |
| 12 x 30 ft | – | $27,000 – $45,000 |
| 14 x 28 ft | $37,000 – $55,000 | $29,400 – $49,000 |
| 15 x 30 ft | – | $33,750 – $56,250 |
| 16 x 32 ft | $48,000 – $70,000 | $38,400 – $64,000 |
Cost by material
The publishers price the same three materials with different ranges123:
| Material | Angi/HomeAdvisor (2026) | Fixr, 16 x 36 ft pool (2025) |
|---|---|---|
| Fiberglass | $9,000 – $40,000 | $15,000 – $35,000 |
| Vinyl | $20,000 – $63,000 | $25,000 – $65,000 |
| Concrete (gunite) | $50,000 – $200,000 | $50,000 – $100,000 |
The publishers disagree on how salt interacts with pool materials, so no material-durability claims appear here; the figures above are prices only.
Cost by pool type
Fixr's installed prices by pool style (2025)3:
| Pool type | Fixr installed (2025) |
|---|---|
| Cocktail | $9,500 – $16,500 |
| Plunge | $13,500 – $24,500 |
| Endless | $26,500 – $37,500 |

| Natural | $71,500 – $102,500 |
| Infinity | $101,500 – $152,500 |
Labor, excavation, and equipment
Fixr puts installation labor at $7,000 to $40,000, with excavation at $500 to $3,500, blasting rocky terrain at $5,000 to $10,000, permits at $200 to $300, and equipment installation – heating, filtration, and chlorinator – at $6,500 to $12,5003. Angi prices excavation at a $3,400 average, reaching $20,000 for difficult sites1. For equipment, Angi puts a pump and filter system at $700 to $1,000 in-ground or from $500 above-ground, a pool heater at $1,600 to $3,800 plus $70 for a corrosion-resistant check valve, and filling the pool with water at $90 to $2701. Fixr's per-item equipment prices: filter $30 to $1,600, pump $300 to $1,200, heater $1,250 to $9,000 installed, and salt chlorine generator $1,500 to $2,5003.
Ongoing costs
Pool salt runs $10 to $40 per 40-pound bag at both Angi and HomeAdvisor12; HomeAdvisor estimates $100 to $300 of salt for a standard 20,000-gallon pool2, and Fixr puts annual salt costs at $100 to $4003. Fixr prices professional maintenance at $900 to $1,500 per year, or $25 to $40 per hour, with salt cell replacement at $200 to $7003. Running the system costs $40 to $60 per month in electricity by Fixr's estimate3, while Angi and HomeAdvisor put the added electricity versus a chlorine pool at about $50 per year12. Cleaning tools cost $25 to $651.
Add-ons
HomeAdvisor prices upgrades like decks, heaters, hot tubs, or lighting at $300 to $12,000 total2. Fixr's per-item add-on prices, installed (2025)3:
| Add-on | Fixr installed (2025) |
|---|---|
| Landscaping rocks | $200 – $400 |
| Ladder | $300 – $700 |

| Enclosure | $10,000 – $30,000 |
What affects the price
Whether you convert an existing pool or build new is the largest cost factor13. Pool size and material drive the build price123. Site conditions set excavation costs – rocky terrain can require blasting13. In-ground pools cost far more than above-ground3. Equipment, add-ons, and regional labor rates move the rest13.
