What a Semi-Inground Pool Really Costs

Just what is the real cost?

Shopping for a pool can be overwhelming—especially when you start comparing above-ground, inground, and semi-inground options. The good news? An Optimum semi-inground pool offers an incredible middle ground between affordability, style, and durability.

Here’s a realistic look at the costs involved and how to make smart financial choices during your project. Let’s find out what a semi-inground pool really costs.

The Price Range: What to Expect

At Fiesta Pools & Spas, a typical semi-inground pool installation can range from $20,500 to $40,000, depending on:

Pool size and shape (round vs. oval)
Depth and partial burial height
Type of decking and fencing
Added features (lights, heaters, covers)
Site prep complexity

While more than a basic above-ground model, it’s significantly more affordable than a full inground installation—which can easily exceed $60,000–$80,000.

What’s Included in the Base Price?

Most semi-inground pool packages from reputable dealers include:

Pool shell
Skimmer and return fittings
Liner
Pump and filter system
Basic installation

What’s often not included: decking, electrical work, retaining walls, landscaping, or permits. Be sure to get a detailed estimate so you’re not surprised down the line.

Smart Ways to Save Without Sacrificing Quality

Choose the Right Size – Bigger isn’t always better. An 18-foot round pool offers plenty of room for fun without overwhelming your yard or budget.
Simple Shapes Save Money – Round and oval pools are more affordable to install than custom shapes.
Build in Phases – Start with the pool and add decking, landscaping, or water features later.
Use Off-Season Pricing – Schedule installs in early spring or late fall when contractors are more flexible and material costs may dip.

Get Financing Help

We offer pool financing options for your semi-inground pool through trusted partners. With low monthly payments, you can enjoy your pool now and spread out the investment over time.

Tax and Insurance Considerations

In some areas, semi-inground pools may not count as permanent structures—potentially lowering your property tax increase compared to a full inground model. Always check with your county assessor and home insurer to be sure.

Think Long-Term Value

A well-designed semi-inground pool boosts curb appeal and property value. Compared to above-ground models, they offer:

Better aesthetics
Longer lifespan
More customization options

So while the upfront cost is higher than a basic above-ground pool, the return on enjoyment—and resale potential—is much greater.

Final Thoughts on the Real Cost

If you’re looking for a premium pool experience without the sky-high price of a full inground install, an Optimum semi-inground pool is one of the best values on the market. With smart planning and expert guidance, you can enjoy a stylish backyard escape that fits your budget and your lifestyle.
