What affects the cost?

  • Material choice — vinyl liner runs $20,000-$80,000 installed, fiberglass $20,000-$100,000, and concrete/gunite $35,000-$120,000, with concrete the most expensive upfront but the longest-lasting (Bob Vila, HomeAdvisor, HomeGuide, Forbes Home)
  • Pool size and square footage, which scales the price directly — HomeGuide shows a 10x20 pool at $16,000-$50,000 versus a 20x40 pool at $64,000-$200,000
  • Excavation and site access — excavation averages about $3,400 but can reach $20,000 on a tight, sloped, or hard-to-access lot (Bob Vila, HomeAdvisor)
  • Decking, which adds $500 to $20,000 depending on material and size (Bob Vila, HomeAdvisor); This Old House cites a narrower $5,000-$20,000 decking range
  • Permits and inspections — permit fees run roughly $100 to $2,000 depending on municipality, plus a $125-$250 inspection fee (HomeGuide, Bob Vila); This Old House cites a higher $450-$1,800 permit range
  • Equipment such as a heater ($1,800-$5,450) and filtration ($500-$3,000), which are commonly priced separately from the base install (HomeAdvisor, This Old House)
  • Labor, which alone runs $5,000-$30,000 depending on material and site complexity — concrete/gunite costs more in labor than fiberglass or vinyl because it's harder and slower to install (Bob Vila, HomeGuide)

Why does an inground pool cost so much?

An inground pool is priced mainly by material and size, and full turn-key installations typically run $25,000 to $100,000, averaging around $41,857 nationally (HomeAdvisor). Bob Vila and Forbes Home report similar averages – $36,730 and $35,000 – while HomeGuide’s data lands in the same $25,000-$100,000 typical range but states a higher $62,500 average, likely reflecting a broader mix of pool sizes and finishes in its dataset. By material, vinyl liner is cheapest at $20,000 to $80,000 installed, fiberglass runs $20,000 to $100,000, and concrete/gunite tops the list at $35,000 to $120,000 (Bob Vila, HomeAdvisor, HomeGuide, Forbes Home). Size matters just as much as material: HomeGuide shows a small 10x20-foot pool running $16,000 to $50,000, while a large 20x40-foot pool runs $64,000 to $200,000. None of these figures typically include ongoing costs like monthly maintenance, which HomeGuide and This Old House put at roughly $80 to $270 a month.

What affects the cost?

A handful of factors explain the gap between a $25,000 pool and a $100,000-plus one:

  • Material. Vinyl liner runs $20,000-$80,000 installed, fiberglass $20,000-$100,000, and concrete/gunite $35,000-$120,000 – concrete costs the most upfront but lasts the longest (Bob Vila, HomeAdvisor, HomeGuide, Forbes Home).
  • Pool size and shape. Cost scales directly with square footage. HomeGuide shows a 10x20 pool at $16,000-$50,000 versus a 20x40 pool at $64,000-$200,000. Chad Christenson, founder of Watermark Pools, says “the shape can also impact installation costs, particularly if it alters the pool’s square footage, the hardscape, or if the installation is complex” (Bob Vila).
  • Excavation and site access. Excavation averages about $3,400, but a tight, sloped, or hard-to-access lot can push it as high as $20,000 (Bob Vila, HomeAdvisor).
  • Decking. Decking adds $500 to $20,000 depending on material and size (Bob Vila, HomeAdvisor), while This Old House cites a narrower $5,000-$20,000 range for the same work.
  • Permits and inspections. Permit fees run roughly $100 to $2,000 depending on the municipality, plus a $125-$250 inspection fee (HomeGuide, Bob Vila); This Old House cites a higher $450-$1,800 permit range in some areas.
  • Equipment. A heater ($1,800-$5,450) and filtration ($500-$3,000) are commonly priced on top of the base install (HomeAdvisor, This Old House).
  • Labor. Labor alone runs $5,000 to $30,000, since concrete/gunite takes more time and skill to install than fiberglass or vinyl (Bob Vila, HomeGuide).

How to lower your inground pool cost

  • Choose vinyl liner or fiberglass over concrete. Vinyl and fiberglass share a $20,000 floor, well below concrete/gunite’s $35,000 starting point (Bob Vila, HomeAdvisor, HomeGuide) – material alone can be the biggest lever on the total price.
  • Get the site evaluated before you budget. Since excavation can run anywhere from about $3,400 to $20,000 depending on access, an early site assessment avoids a budget built around the low end (Bob Vila, HomeAdvisor).
  • Right-size the pool. A smaller footprint has an outsized effect on price – HomeGuide’s data shows roughly a 4x cost difference between a 10x20 pool and a 20x40 pool.
  • Phase in decking, fencing, and equipment. Decking ($500-$20,000), fencing ($3,000-$10,000), and a heater ($1,800-$5,450) are commonly quoted as separate line items and can often be added after the pool itself is budgeted for (Bob Vila, HomeAdvisor, This Old House).
  • Confirm what a turn-key quote includes. Forbes Home notes turn-key packages run $35,000 to $100,000 versus itemized DIY-style pricing that breaks out excavation, the shell, and equipment separately – knowing which model a quote uses makes it easier to compare bids.

Prices vary widely by region, pool size, and material, so treat the figures above as a planning budget. Get two or three local quotes, and confirm whether excavation, permits, decking, and standard equipment are included before comparing numbers.

Frequently asked questions

How much does it cost to install an inground pool?
Most homeowners pay $25,000 to $100,000 for a full inground pool installation, averaging around $41,857 nationally (HomeAdvisor). HomeGuide's data lands in the same $25,000-$100,000 band, though its stated national average of $62,500 runs higher than HomeAdvisor's, Bob Vila's ($36,730), or Forbes Home's ($35,000).
What's the cheapest type of inground pool?
Vinyl liner is the least expensive option, running $20,000 to $80,000 installed (HomeGuide), with Bob Vila and HomeAdvisor both citing a tighter $20,000-$40,000 range for a standard vinyl build.
Is a concrete or gunite pool worth the extra cost?
Concrete/gunite runs $35,000 to $120,000 installed, the highest of the three materials (Bob Vila, HomeAdvisor, HomeGuide), but it's also the most customizable and longest-lasting option, which is why it commands a premium.
How much does excavation cost for an inground pool?
Excavation averages about $3,400, according to both Bob Vila and HomeAdvisor, but a tight, sloped, or hard-to-access lot can push that as high as $20,000.
Does the price include decking, permits, and fencing?
Usually not as a single bundled number. Decking commonly runs $500 to $20,000 (Bob Vila, HomeAdvisor), permits run roughly $100 to $2,000 depending on the municipality (HomeGuide, Bob Vila), and This Old House cites fencing separately at $3,000 to $10,000.
How much more does a fiberglass pool cost than vinyl?
Fiberglass runs $20,000 to $100,000 installed versus $20,000 to $80,000 for vinyl liner (HomeGuide) -- the two materials share a similar low end, but fiberglass has a higher ceiling on larger or premium builds.
Why do inground pool cost estimates vary so much between sources?
Sources report the 'national average' differently: Forbes Home, Bob Vila, and HomeAdvisor cluster around $35,000-$41,857, while HomeGuide reports a notably higher $62,500 average from the same $25,000-$100,000 typical range. By-size and by-material figures also vary since sources differ on what's bundled in -- some include standard decking and equipment, others price the shell and labor separately.

Reported national averages cluster in two groups: Forbes Home ($35,000), Bob Vila ($36,730), and HomeAdvisor ($41,857) sit close together, while HomeGuide reports a notably higher $62,500 average and This Old House states no single average but shows $38,000-$100,000 for a common 12x24-foot pool. national_average_usd uses HomeAdvisor's $41,857, the figure at the center of the tighter three-source cluster. The headline range_low_usd/range_high_usd of $25,000-$100,000 is taken directly from HomeGuide's stated 'Average Range,' which also brackets HomeAdvisor's normal-range low ($25,024) and Forbes Home's low ($28,000), and lines up with This Old House's 12x24-foot high end ($100,000) -- it represents a realistic span from a modest vinyl or fiberglass build to a larger or concrete project, not the full extremes some sources cite (Bob Vila's overall floor is $1,800 for a tiny plunge-style pool, and custom luxury builds can run past $125,000-$200,000 per Bob Vila and HomeGuide). by_type ranges use the full span each material was cited at across Bob Vila, HomeAdvisor, HomeGuide, and Forbes Home; HomeGuide consistently prices all three materials higher than the other sources, which pulls up the top end of each range. HomeGuide is also internally inconsistent on vinyl, stating both '$35,000-$80,000' in its comparison table and '$25,000-$65,000' in body text -- the wider table figure is used here as the upper bound. Figures generally represent a full turn-key installation (shell, excavation, standard equipment, basic decking); permits, fencing, a heater, saltwater conversion, and premium decking or landscaping are commonly quoted as separate add-ons.
