Installing an inground pool typically costs $50,000 to $220,000+, with most homeowners landing in the $65,000–$130,000 range for a standard vinyl liner or fibreglass pool. Concrete and ICF builds run higher, usually $100,000–$200,000+, because they’re engineered and poured on site rather than installed as a pre-built shell.
The number you’ll actually pay depends on three things: the pool material you choose, the size and depth you build to, and a handful of site-specific budget factors — soil, access, and permits — that can swing a quote by tens of thousands of dollars even between two similar-looking pools. This guide breaks down all three.
How Much Does an Inground Pool Cost by Type?
| Pool Type | Typical Installed Cost | Lifespan / Key Trade-Off |
| Vinyl liner | $50,000 – $90,000 | Lowest upfront cost; liner replacement every 7–12 years ($4,000–$7,000) |
| Fibreglass | $65,000 – $120,000 | Higher upfront cost; lowest long-term maintenance |
| ICF (insulated concrete form) | $110,000 – $200,000+ | Energy-efficient, freeze-thaw resistant; less design flexibility than poured concrete |
| Concrete (gunite) | $100,000 – $220,000+ | Full design freedom; needs resurfacing every 10–20 years ($6,000–$18,000) |
Vinyl Liner
A steel or polymer wall panel system is custom-fit to your yard, then lined with a vinyl liner. This is the most budget-accessible inground option and the one most homeowners start with — most standard-size builds land at $50,000–$90,000. Vinyl can be shaped almost any way you like, which makes it popular for irregular lots.
Fibreglass
A one-piece shell is manufactured off-site, then delivered and craned into the excavated hole. That pre-fabrication is why fibreglass installs faster than concrete and why pricing is more predictable — typically $65,000–$120,000. The smooth gelcoat surface also resists algae, which is why fibreglass tends to have the lowest day-to-day maintenance of the three core materials.
ICF (Insulated Concrete Form)
Reinforced concrete poured into insulated foam forms — essentially a concrete pool with a built-in insulation layer. ICF suits Ontario’s freeze-thaw climate well and can reduce heating costs over time, but expect $110,000–$200,000+ given the engineering involved.
Concrete (Gunite/Shotcrete)
Built entirely on site using rebar, formwork, and pressure-applied concrete, then finished with plaster, pebble, or tile. This is the only material that gives you full control over shape, depth, built-in benches, and integrated features — which is why it’s the choice for architectural or resort-style pools. Standard concrete builds run $100,000–$150,000, with premium custom projects regularly exceeding $200,000.
Inground Pool Cost by Size and Depth
Size determines excavation volume, water capacity, and how much shell material you need — it’s usually the second-biggest cost driver after material choice.
| Size | Approx. Water Volume | Typical Installed Cost |
| 12′ x 24′ (small) | ~30,000 L (8,000 US gal) | $50,000 – $80,000 |
| 14′ x 28′ (standard) | ~35,000 L (9,200 US gal) | $65,000 – $110,000 |
| 16′ x 32′ (mid-size) | ~45,000 L (12,000 US gal) | $75,000 – $130,000 |
| 18′ x 36′ (large) | ~92,000 L (24,300 US gal) | $90,000 – $160,000 |
| 20′ x 40’+ (extra-large) | ~114,000 L (30,000 US gal) | $100,000 – $180,000+ |

How Depth Changes the Price
Most pools are built to a standard 3.5–6 ft depth. Going deeper adds cost in three places at once: more excavation, more structural reinforcement, and a larger pump/filter system to manage the extra water volume.
- Diving depth (8–10 ft): typically adds $15,000–$30,000 over a standard-depth build, or roughly 15–25% of total project cost.
- High water table sites: if your deep end sits below the local water table — common in parts of Ajax, Burlington, and areas closer to the lake — you may need sump pumps or drainage systems to prevent the shell from shifting, adding $5,000–$10,000.
Cost Per Square Foot
Per-square-foot pricing is a useful way to sanity-check a quote once you know your target size:
| Material | Typical Cost per Sq. Ft. (Installed) |
| Vinyl liner | $175 – $230 |
| Fibreglass | $200 – $280 |
| Concrete / ICF | $250 – $350+ |
These figures include the shell, excavation, plumbing, and electrical — not landscaping, fencing, or premium water features. Use them as a planning benchmark, not a final number; two contractors quoting the same square footage can still land $20,000 or more apart depending on equipment quality and site conditions.
Budget Factors That Move Your Price Up or Down
Beyond material and size, these are the variables that most often explain why two seemingly identical pools end up at very different price points:
- Site access — tight side-yard gates or fences that block standard excavators force a switch to smaller equipment or hand-digging, which slows the job and raises labour cost.
- Soil conditions — clay, shale, or rocky ground is harder (and slower) to excavate than sand or loam, typically adding $3,000–$10,000.
- Slope and grading — sloped backyards often need retaining walls before a pool can even be sited, which can add $15,000+.
- Shape complexity — a straight rectangle is the most efficient shape to build. Freeform curves, tanning ledges, beach entries, and built-in benches all add labour and material.
- Distance from equipment pad to pool — longer plumbing and electrical runs mean more material and labour.
- Permits and engineering — most municipalities charge $150–$750 for a basic building permit, though plan review and engineering can push this to $500–$2,500 on more complex lots. Sites with excavation near a foundation or retaining wall may require additional engineering drawings. Toronto-specific permit detail: Pool Permits Toronto.
- Contractor and equipment tier — the same pool size can vary by $20,000 or more between contractors depending on equipment brand, warranty terms, and crew experience. This is the single biggest argument for collecting multiple itemized quotes rather than comparing headline prices.
- Time of year — spring is peak booking season for GTA pool builders; scheduling in late summer or fall sometimes opens up more flexible pricing.
What’s Typically Included in a Base Quote
A standard inground pool quote usually covers:
- Excavation and soil removal
- The pool shell (vinyl wall system + liner, fibreglass shell, or poured concrete)
- Plumbing (skimmers, main drain, return jets)
- Pump and filter system
- Electrical connection and one pool light
- Basic coping
It generally excludes a heater, upgraded lighting, water features, automation, fencing, and finished decking — all priced as add-ons. For a full add-on cost breakdown across every pool type, see Pool Installation Cost Toronto.
Smart Ways to Budget for an Inground Pool
- Build in a 10–15% contingency. Site surprises — rock, unexpected drainage issues, buried utilities — are common enough that experienced contractors plan for them by default.
- Get itemized quotes, not lump-sum numbers. A detailed quote should break out excavation, shell, coping, equipment, and permits separately, so you can see exactly what’s driving the total.
- Start with a standard shape. You can always add a water feature or tanning ledge later; a rectangular pool is the cheapest shape to build correctly the first time.
- Phase your extras. Many homeowners install the pool shell and basic decking first, then add heating, lighting, or landscaping in a later season once the core budget has settled.
Ongoing Costs After Installation
Installation is the largest cost, but not the only one. Plan for:
- Spring opening: $150–$350
- Fall closing/winterization: $200–$450
- Chemicals and water care: $500–$1,200/year
- Equipment servicing: $200–$400/year
- Vinyl liner replacement (every 7–12 years): $4,000–$7,000
- Concrete resurfacing (every 10–20 years): $6,000–$18,000

Frequently Asked Questions
What is the average cost of an inground pool?
Most homeowners spend $65,000–$130,000 for a standard vinyl or fibreglass inground pool, all-in. Concrete and ICF builds typically run $100,000–$220,000+.
Which inground pool type is cheapest to install?
Vinyl liner pools have the lowest upfront cost, typically $50,000–$90,000, though they carry a recurring liner-replacement cost every 7–12 years that fibreglass and concrete don’t.
How much does pool depth affect the price?
Going to diving depth (8–10 ft) instead of a standard 3.5–6 ft depth typically adds $15,000–$30,000, or 15–25% of total project cost.
Why do quotes for the same size pool vary so much between contractors?
Equipment brand, warranty terms, crew experience, and how thoroughly a contractor accounts for soil and access conditions can create a $20,000+ spread between quotes for a similarly sized pool. Always compare itemized quotes.
Does the quote include permits and fencing?
Typically not. Budget separately for a building permit ($150–$750, more with engineering review) and a code-compliant pool fence, which most municipalities require before the pool can be filled.
