Semi-Inground Pool Cost Calculator
If you’re looking for the perfect middle ground between an above-ground and an inground pool, a semi-inground pool might be the answer. It combines the durability and sleek look of an inground pool with the affordability and flexibility of an above-ground model. Use our Semi-Inground Pool Cost Calculator to estimate installation, materials, and optional upgrades for your ideal setup.
What Is a Semi-Inground Pool?
A semi-inground pool is installed partially in the ground and partially above it—typically 18–36 inches raised. It’s a popular choice for sloped yards or homeowners who want the aesthetic of an inground pool without the full excavation cost.
Benefits of Semi-Inground Pools
- Lower cost than fully inground pools. For an even more budget-friendly option, consider an above-ground pool
- Easier installation on uneven terrain
- Can be customized with decks or landscaping
- More durable than standard above-ground pools
- Modern, stylish appearance

Pool Type | Average Cost Installed |
Aluminum or Steel Wall | $10,000 – $20,000 |
Resin or Hybrid Pool | $12,000 – $25,000 |
Semi-Inground Fiberglass | $20,000 – $40,000 |
Semi-Inground Concrete | $25,000 – $50,000 |
