When it comes to selecting the liner for an in-ground swimming pool, there are a few different options. Concrete, tile, fiberglass and vinyl are all suitable options based on the needs of the pool owner. Essentially, the “liner” is responsible for holding the water in the pool, and providing aesthetic value to the pool area. Depending on the situation, the cost of a liner can vary greatly. This article will touch on the different aspects of vinyl pool liners, and what should be considered when purchasing.
First off, vinyl pool liners are great for in-ground and above-ground pools. This makes them the most popular option among pool owners. As mentioned above, their purpose is to prevent leaks and keep water inside the pool. Their other goal is to provide an aesthetically pleasing background for the pool area. Many stores and distributors offer several different patterns to accommodate any design scheme. Another huge benefit of vinyl liners is that they are available in different sizes and thicknesses. Fiberglass pools specifically, are only available in predetermined sizes and shapes.
Gauge – Mil (Thickness) Considerations
When deciding what the best liner thicknesses for an in-ground pool or above ground pool, a variety of factors should be considered. The most important consideration is sun exposure. The location of the pool in relation to the amount of direct sunlight will affect the thickness needed in order to prevent premature fading and damage. If the pool will experience longer exposure to direct sunlight throughout the year the preferred mil should be 28-30. Although the thicker mil liners tend to cost an average of 5-10% more, they will provide an adequate layer of protection to help prevent premature damage. Also, vinyl liners will provide the same smooth surface regardless of the mil chosen.
Maintenance Considerations
The most important aspect of maintaining vinyl pool liners is water chemistry. Water balance is a huge factor in keeping not only the pool healthy, but the liner as well. The most important factor of water chemistry is pH. The pH should never fall below 7.0, which would mean it is acidic. When the water is this acidic, it can cause complications such as permanent wrinkles and premature aging. An important tip to remember when draining and filling is to never drain the pool to where there is less than one foot of water in the shallow end. Pool liners rely on pressure to maintain a wrinkle free, smooth liner. When too much water is removed, the risk of the liner shrinking increases.

The Pros and Cons
This list will give a quick breakdown of the pros and cons of using vinyl pool liners versus concrete, tile or fiberglass. Cost, installation, customization, replacement, resell value and maintenance upkeep should all be considered as you move through the purchasing process. Vinyl liners have become the most popular choice due to their low cost, quick instillation time and customizability. However, maintenance, durability and resale value should be considered when choosing.
The Pros
- Price
Vinyl pool liners are extremely cost effective. Generally, vinyl liners have a lower installation and purchasing cost than fiberglass and concrete pools – this is due to lower materials costs, as well as labor. They are a perfect option for those who have a budget between $25k and $35k.
- Quick Installation
Compared to other pools, vinyl liners usually have quicker installation time – granting you the maximum amount of time to enjoy your pool. Vinyl liners are available in ready-to-assemble kits for installation by homeowners or professional installers.
- Customization
As mentioned above, vinyl liners have several customizable options. Not only can they be used in a wide variety of different shaped pools, but they are available in different thicknesses as well. As far as the appearance, most distributors offer as many as 30 different patterns or tiles to fit whatever theme there might have in the pool area. While concrete pools offer the ability to choose the shape of the pool, it is often costly.
The Cons
- Maintenance
Overall, vinyl liner maintenance is fairly simple. However, with the instillation of pool accessories such as steps, ladders or lights, the metal components can cause permanent rust stains on the liner. Improper water balance can also cause the liner to become extremely slippery. Along with water balance, chlorine staining is also frequent in vinyl liners. This can occur when powdered chlorine is not properly circulated in the pool, and dissolves in one area. Weekly vacuuming, chemical adjusting and skimming is required to keep the liner in top-notch condition.
- Durability
Despite long warranties, the average vinyl liner lasts anywhere between 8 and 10 years. Keep in mind that these are estimates. If the liner is taken care of it is not uncommon for it to last upwards of 15 years. Replacement costs are usually between $3,500 and $5,000.
- Resell Value
Generally speaking, pools with a vinyl liner have a lower resale value than fiberglass or concrete pools. Fiberglass and concrete pools are viewed as long term structures, while vinyl lined pools (in-ground or above-ground) are considered more short term. In addition, many prospecting home owners are hesitant about vinyl liners because of the inevitable upkeep costs down the road.
