How Much Does Pool Liner Replacement Cost in St. Louis? [2025 Data]

Pool liner replacement costs in St. Louis total $940, on average, and most residents pay between $483 and $1,455. Your total will depend on the type of pool you have, the size and shape, and the type and quality of the liner. Below-average lot sizes in St. Louis mean the average pool is on the small side, which helps keep costs down, but your total could be higher than the average if you have a larger pool.

Pool Liner Replacement Cost Factors

You could pay as little as $175 or as much as $2,900 to hire a professional installer for your pool liner replacement in St. Louis. The wide cost range is due to a few main cost factors that affect your pricing.

Size

Pool liner replacement costs in St. Louis depend on the size of your pool, as material and labor costs increase with the size. You’ll pay an average of $4 per square foot for your pool liner replacement, so measuring your pool’s square footage is a good place to start to get an accurate estimate. St. Louis lot sizes average about 1 acre, which means most homeowners have smaller pools that contribute to below-average liner costs.

Pool Type

Installing a new liner in an in-ground pool costs two to three times as much as installing one in an aboveground pool. Aboveground pools are more common in St. Louis than in many other areas throughout the U.S., and this is another big reason that the cost to replace a pool liner in St. Louis is well below the national average.

Type of Liner

An overlap pool liner is the most affordable type of pool liner and is the most common option for aboveground pools. For in-ground pools, uni-bead liners and beaded liners are the available options. Uni-bead liners can be suitable in St. Louis, especially in the more densely populated urban areas. In most of the St. Louis metropolitan area, though, frequent tornado activity can shift uni-bead liners—so beaded liners, while more expensive, are the better option.

St. Louis sees more rainfall than most other areas of the country, and rain can introduce bacteria and promote algae growth. To combat these effects and reduce maintenance costs, it’s a good idea to invest in a cover with antimicrobial properties.

Liner Thickness

The thickness of the liner you install will also affect the material costs. Most liners for residential pools are between 20 and 30 mils thick, and the thicker you go, the more you’ll pay.

While thicker is more expensive, this is one place where it can pay to invest a bit more, especially in St. Louis. Not only will thicker liners last longer, but they’ll also resist damage from blown debris during extreme weather. 

As the metropolitan area in the U.S. most often hit with tornadoes, St. Louis also sees intense thunderstorms that can bring strong winds. You’ll be less likely to have to patch your pool liner if you invest in a thicker material up front.

Additionally, thicker liners better resist cracking and deterioration during temperature swings, and since St. Louis sees hot summers and winters that reach freezing temperatures, you’ll get more value from a thicker liner.

Pool Liner Pro Costs

Hiring a pool liner installer in St. Louis costs an average of $560 for labor, accounting for 60% of your total costs. This is well below the national average, in part because the cost of living in St. Louis is below the average. However, it’s also because many pools in the city are on the smaller side due to space constraints.

Does a New Pool Liner Increase Home Value?

Installing a new pool liner will have a positive impact on your home value in St. Louis. A new liner can spruce up your entertaining area, which will be appealing to buyers, and it can reassure them that liner replacement isn’t an expense they’ll need to worry about shortly after purchasing the home. However, the bump in home value will be a minor one.
