How Much Does an In-Ground Pool Cost in St. Louis? [2025 Data]

Located near the center of the United States, St. Louis has all four seasons and offers warm summers that are ideal for using an in-ground pool. If you’re ready to ramp up your summer, in-ground pool costs in St. Louis average between $43,500 and $100,000, but homeowners pay an average of $68,500. A local pro will assess the size, shape, features, and site prep costs before giving you a quote.

In-Ground Pool Cost Factors

There’s no one-size-fits-all type of pool. Before breaking ground, you’ll need to choose the in-ground pool shape as well as size. You’ll also need to factor in site prep costs, added features, and lighting to get the most accurate quote possible for the in-ground pool cost in St. Louis. 

Pool Type and Materials

Vinyl and fiberglass pools are the most affordable, but concrete offers more customizations and the ability to finish with tiles or plaster, and the price reflects that. Use the table below to get an estimate for what your pool could cost based on the material you choose.

• Vinyl: If you want to keep costs lower, you can choose a vinyl pool. This type of pool falls on the lower end of the cost range, but the liner can last for 10 years or more with proper maintenance. Liner replacement will extend the pool’s life and allow you to enjoy your pool for years to come.

• Fiberglass: Fiberglass pools are prefabricated, which makes installation faster and easier. But this material doesn’t offer the same design flexibility that concrete does. Small cracks can be patched, but fiberglass pools are prone to cracking over time.  

• Concrete: For a highly customizable pool, concrete offers lots of flexibility when it comes to shape and finishes. Poured concrete can create any shape you design, and tile, stone, or plaster finishes make it a one-of-a-kind pool. To keep it in good shape, you’ll have to resurface the concrete every 10 years, and another downside is that this is the most expensive type of pool.  

Size

The pool size will have a major impact on the ultimate project cost. Typically, pool costs range between $90 and $150 per square foot, so you can use the size of your pool as a guide to get a rough estimate of the total cost. If you want to play around with in-ground pool shapes, your contractor can help you determine how that will affect the final cost. 

Additional Costs

In-ground pools are much more than just a place to cool off. They can bring family and friends together, offer a relaxing retreat in your very own backyard, and even act as a place to exercise. To complete the pool, you’ll need to add lighting, a pool cover, pool fencing, landscaping, and more, which create additional costs.

• Pool lighting: $200 per light

• Solar pool cover: $75–$300

• Hot tub: $5,000–$20,000

• Slide: $1,500–$20,000

• Landscaping: $700–$3,300

• Pool fence: $1,500–$10,000

• Site prep: $500–$3,020

• Yearly pool maintenance cost: $120–$5,000

Climate

St. Louis is located near the center of the U.S., and has a four-season climate that results from warm air from the Gulf of Mexico prevailing during the summer months and cold air from Canada prevailing in the winter months. While temperatures can dip below freezing in the winter, they don’t stay there for too long, and the city doesn’t have many days of frigid temperatures to contend with.

In-Ground Pool Pro Costs

Installing an in-ground pool requires technical knowledge and skill to actually complete the project. But it also requires knowledge of local building codes, required permits, and subcontractors who can help bring the project to life. Working with a local in-ground pool company can help the process go smoothly. 

Building Code Requirements

Saint Louis County provides an extensive checklist and guide for a building permit that serves as a supplement to the actual construction codes and policies that the pool must meet. The county also provides a Pool Permit Requirement Checklist, which covers commonly missed building code requirements that are left out of the design phase. Your local swimming pool contractor will be able to walk you through building code requirements and ensure they’re being met throughout the process. 

Permits and Inspections

To begin an in-ground pool project, you first need to obtain a Swimming Pool Permit from Saint Louis County Transportation and Public Works. This permit also includes a section related to the electrical work needed for the pool. Your swimming pool contractor can help you fill out the paperwork correctly and will know what inspections are necessary throughout the process.

Labor

Labor costs to install an in-ground pool typically fall between $55 and $150 per hour and make up between 25% and 50% of the total project cost. Check with your contractor during the planning and estimating phase to determine how they calculate labor costs and how it will affect the final amount that you’ll pay for the project. 

Property Taxes

Property tax rates in St. Louis are higher than in many areas of the country at $8.3708 per $100 of assessed property value, which equals around 19% of the home’s market value. When you build an in-ground pool in St. Louis, it will raise the home value of your property, which will also increase the assessed value and, ultimately, your tax bill. Make sure you’re aware of how this project will affect the amount you owe in taxes each year, and then budget accordingly.

Does an In-Ground Pool Increase Home Value?

Assuming your in-ground pool is well-maintained, it can boost your home’s property value by around 7% in St. Louis. The pool’s return on investment falls between 5% and 56%, and that wide range is due to factors like climate, pool maintenance, neighborhoods, and more. While you can expect an in-ground pool to increase your home’s value, you’ll also have to consider your budget and other factors in your specific area.
