Installing a lap pool costs $44,000 on average, according to Angi (updated October 2026): most homeowners spend $6,000 to $80,000, with costs climbing as high as $100,000 for in-ground or indoor builds. Angi’s summary also states a wider range, but the article does not establish its low-end scope, so it is omitted1. HomeAdvisor – corporate sibling publishing matching figures, which alone do not establish independent corroboration – reports the same $44,000 average and $6,000 to $80,000 normal range, from $4,000 on the low end to $100,000 or more on the high end (updated June 2026)2. Fixr, an unaffiliated publisher, puts the national average at $50,000 for a defined build – a 45 x 8 foot fiberglass in-ground lap pool, 4 feet deep, with a heater and accessories – within a $40,000 to $65,000 range, from $16,000 for a small above-ground pool to $100,000 for an indoor in-ground heated pool with finishing details (updated January 2025)3. The averages carry different stated scopes, and no conclusion about the gap follows.
Cost by size
Angi and HomeAdvisor price three course lengths (2026)12; Fixr prices common residential dimensions installed (2025)3:
| Size | Angi/HomeAdvisor (2026) | Fixr installed (2025) |
|---|---|---|
| 40 ft (standard residential) | $45,000 | – |
| 82 ft / 25 m (short course) | $100,000 – $400,000 | – |
| 164 ft / 50 m (Olympic) | $300,000 – $500,000 | – |
| 35 x 8 ft | – | $30,000 – $45,000 |
| 40 x 8 ft | – | $35,000 – $50,000 |
| 40 x 10 ft | – | $35,000 – $55,000 |
| 45 x 8 ft | – | $40,000 – $65,000 |
| 45 x 10 ft | – | $60,000 – $65,000 |
| 50 x 10 ft | – | $65,000 – $70,000 |
| 75 x 8 ft | – | $70,000 – $80,000 |
| 75 x 10 ft | – | $80,000 – $85,000 |
Widths typically run 6 to 10 feet1. Fixr prices a 25-yard (75 ft) pool at $70,000 to $85,000 depending on width3.
Cost by material
Angi prices surface materials per square foot (2026)1; Fixr prices them installed (2025)3:
| Material | Angi per sq ft (2026) | Fixr installed (2025) |
|---|---|---|
| Vinyl | $21 | $40,000 – $50,000 |
| Fiberglass | $35 – $66 | $50,000 – $60,000 |
| Concrete | $55 – $72 | $60,000 – $70,000 |
| Stainless steel | $128 (stainless steel and copper) | $75,000 – $85,000 |
The columns use different units and scopes, so they are not directly comparable; most residential lap pools measure 8 x 40 feet and 4 feet deep1. Material-durability and maintenance claims are omitted; the figures above are prices only.
Cost by type
Angi and HomeAdvisor's type figures (2026)12, and Fixr's installed type ranges (2025)3:
| Type | Angi/HomeAdvisor (2026) | Fixr installed (2025) |
|---|---|---|
| Above-ground | $6,000 with labor ($3,000 DIY) | $16,000 – $55,000 |
| In-ground | $67,000 average, up to $135,000 | $40,000 – $65,000 |
| Indoor | $50,000 – $100,000 in-ground | $50,000 – $100,000 |
| Infinity | $80,000 – $130,000 | $40,000 – $85,000 |
| Saltwater | about $50,000 | $30,000 – $75,000 |
| Heated | – | $30,000 – $80,000 |
| Endless | starts at about $24,000 | – |
The publishers' above-ground figures diverge, and the pages state no shared sourcing; Fixr notes basic above-ground kits as low as $6,0003. Fixr states two conflicting ranges for endless pools, so its endless figure is omitted; Angi and HomeAdvisor's figure is shown. A saltwater-chlorine generator adds $500 to $2,50012.
Labor
Labor accounts for 25% to 50% of the total project cost at both Angi and Fixr13; these are separately published figures, and the pages state no shared sourcing. HomeAdvisor prices labor at $5.50 per square foot and separately states a $3,800 total for a 40-by-8-by-4-foot average-size unit without specifying the area basis; it also notes in-ground installation labor can reach $40,0002. Angi prices subcontractors at $45 to $200 per hour for a plumber, $50 to $100 per hour for an electrician, $600 to $2,500 for a pool designer, and $1,000 to $1,500 for a land excavator1.
Site preparation and permits
Excavation for a 40-foot pool costs $1,000 to $1,500, with hauling away excess dirt adding roughly $60012. Yard leveling runs $200 to $9001, and permits average around $1,00012 – HomeAdvisor prices indoor building permit charges at $500 to $1,0002. Fill water costs about $1.50 per 1,000 gallons1.
