HomeAdvisor puts the national range for inground pools at $20,000 to $100,000, with the average custom build coming in around $50,000. In South Florida, where pools get used 12 months a year, that figure tends to land on the higher end once site conditions and upgrades are factored in. Pricing swings dramatically depending on size, materials, and what goes into the water. Getting a handle on those variables before sitting down with a builder leads to better conversations and fewer surprises.
What Is the Average Custom Inground Pool Cost?
Custom inground pools are a substantial investment at every budget tier. The table below outlines what most homeowners can expect to spend and what that money covers:
| Budget Level | Estimated Cost Range | What It Typically Includes |
|---|---|---|
| Entry-Level Custom | $35,000 – $50,000 | Standard shape, basic finishes, minimal features |
| Mid-Range Custom | $55,000 – $80,000 | Freeform shape, upgraded plaster, a few add-ons |
| High-End Custom | $85,000 – $100,000+ | Water features, premium decking, automation, lighting |
“Custom” means the pool is built around the property and the homeowner, not pulled from a catalog. Shape, finish, depth, and layout are all on the table. That design freedom is also what makes flat-rate pricing impossible; a site visit is the only way to arrive at an accurate number.
What Factors Really Drive Custom Pool Pricing?
No two pools cost the same. Here are the variables that move the needle most.
Design and Size
Square footage is the most direct cost driver. Non-standard shapes, freeform curves, and added depth all require more excavation, more materials, and more labor hours than a basic rectangle.
Materials
Concrete/gunite, vinyl liner, and fiberglass are the three main construction types. Gunite is the go-to for custom builds because it can take any shape, though it costs the most upfront and demands more maintenance over time. Vinyl liner pools are less expensive to install but need a new liner every eight to 12 years. Fiberglass shells arrive prefabricated, which cuts installation time but limits shape options.

Site Preparation
What is underground matters as much as what goes above it. Rocky soil, a high water table, poor drainage, or a yard with limited equipment access can all push preparation costs up sharply. Sloped lots add retaining work. These are the line items that catch first-time buyers off guard more than any other.
Features and Add-Ons
Tanning ledges, waterfalls, built-in spas, lighting, heaters, automation systems, and decking are all separate costs on top of the pool itself. Browse the custom pool options at Champion Pools for a full picture of what is available and what each category adds to a project.
How Custom Features Affect Cost
Upgrades are where budgets stretch fast. The ranges below reflect typical costs for popular add-ons:
- Beach entries (zero-depth): $3,000 to $8,000
- Built-in spa or hot tub: $8,000 to $15,000
- Waterfalls or sheer descents: $1,500 to $5,000 per feature
- LED lighting packages: $1,500 to $4,000
- Automation and control systems: $1,500 to $3,500
- Pool heaters: $1,600 to $3,800
Which upgrades make sense depends on how the pool will actually get used. Households with small children tend to focus on shallow entries and safety. Those who host often put money toward spa jets, ambient lighting, and decking. Pairing the pool with the right outdoor living setup can tie the whole backyard together. Reviewing those options with a builder early keeps the project from expanding in ways that were never planned.
How to Budget for Your Custom Pool
Costs are easiest to control when the scope is locked in before construction starts. Begin with the non-negotiables: pool shape, minimum size, and must-have features. Everything else can be weighted against budget once the baseline is established.
A site evaluation early in the process is worth scheduling. Soil conditions and access limitations routinely shift final costs more than homeowners anticipate. When comparing bids, confirm that each one covers the same scope. A lower number that strips out permits, electrical work, or decking will not stay lower for long.
South Florida pools run year-round, so ongoing maintenance costs (chemicals, cleaning, and periodic equipment work) are a real line item. Champion Pools offers financing options that spread the investment over time. Contact Champion Pools to ask about current arrangements and request a detailed, itemized estimate.
