What Is A Pool Liner?

Empty pool with liner, mosaic tile, and metal ladderPool liners are particularly important because what they offer is the provision of a barrier between the water contained in the pool and its actual walls. There are lots of inground pools that are tiled and in turn, this completely eliminates the need for a pool liner, to begin with.

Pools that are installed with a vinyl liner usually have a foam cushion that serves as a buffer between the pool wall and the liner surface. It can dramatically improve the appearance of the pool and can create a much more inviting surface at the end of the day.

Outdoor pool with vinyl linerWhat you need to know about modern vinyl pool liners is that they happen to be impressively durable. The beauty is really in its material. A pool with a vinyl liner won’t be requiring as many chemicals as a concrete tiled pool would normally do.

Its surface is smooth and seamless and this can make it very difficult for algae and other types of contaminants to cause any sort of damage to your pool.

Overlap Liners

pool with vinyl liner, and copingOverlap pool liners have been known to be the main liner type when it comes to above ground pools. Back in the 80s, overlap pool liners were all the rage. They also typically came in only one color: solid blue.

Over time though, overlap pool liners have come with more patterns and other designs in them. Despite all of the progress and innovations though, classic blue still happens to reign supreme.

An overlap liner is exactly what it’s called. It is placed directly on the pool surface and is designed to have some excess provisions compared to the area surface required for the wall.

Once the overlap pool liner has been set in place, whatever excess material is pulled up over the wall and lain along the top of the pool, in the outside part of it. It is then secured at the top of the wall with a material called coping strips, and then the excess material is eventually cut off for a clean finish.

Benefits and Drawbacks Of Overlap Liners

Here we share the advantages and disadvantages of overlap pool liners.


One of the main attractions of overlap pool liners is that they cost less compared to the other types of pool liners out there. If you’re on a bit of a budget, this can turn out to be an excellent choice of liner for you.

This is also great for irregular swimming pool shapes or with issues with leveling. Poorly installed, misshapen, as well as off-level pools, can be a real challenge to deal with but overlap liners can make this so much easier.

An overlap pool liner is versatile enough to provide varying wall heights as it all depends on how much material you actually have. It can accommodate pool heights at 48” or even 54” or higher.


Because overlap liners aren’t typically tailored to fit your pool size, you would have to handle the issue of excess material. This can at times be slightly visible on the outside area of the pool.

This can not only cover the outer design of the pool but can overall make the pool look unattractive. A solution to this would be to roll the excess material up and hide it under the top of the rails.

This type of liner will require coping strips. These strips will also need to be replaced every time there’s a need for you to replace the pool liner.

This can be very hard to do yourself and you would need professionals to get the job done properly.

If you happen to have an above ground pool that’s buried partially or even fully, it can be problematic to replace an existing overlap pool liner.

How Long do Overlap Liners Last?

An overlap pool liner will last for a range of 5 to 8 years but the warranty coverage can range anywhere from 15 to 20 years depending on the overlap liner pool type as well as the manufacturer.

The printed ones usually have a shorter life span of 3 to 5 years but overall, it depends on how the pool is used and what type of exposure it has against the elements. It also depends on how well the pool is maintained.

Expandable Liners

Indoor pool liner, steps, metal railingAn expandable pool liner is a liner type that can accommodate pools as deep as 72” on the deep end. They typically come in varying stock sizes and are typically made out of 20 gauge vinyl.

They are perfect for fitting Doughboy pools as well as any other pool that might require a more expansive coverage from a vinyl liner. Expandable pool liners are a type of overlap liner that come with a 72” wall.

Because of its extra material, it’s capable of providing coverage for deeper above ground pool types. If you have a pool with different depths or levels, an expandable pool liner can still work remarkably well as it allows itself to sit right on top of your pool floor, then extends out to the walls, and whatever excess material you have, you can actually just trim off.

Advantages and Limitations Of Expandable Liners

Here we share the advantages and disadvantages of expandable pool liners


They are cost-efficient. This is because they’re a type of overlap liner, which happens to be the cheapest among all the types. 

They can handle pools with irregular shapes, differing levels, or even pool finishes.

They’re suitable for any pool height and can go as high as 72” for the pool walls.

Its material drops down to the dug out depth which means it’s actually “stretch-to-fit”.


Its name can be misleading as it doesn’t actually stretch at all any more than the rest of the other liners don’t stretch. It simply has extra material for the walls that makes it seems like it can “stretch” into any pool size and type”.

The excess material for the walls can look unattractive if not handled neatly and professionally when you trim them.

How Long Do Expandable Liners Last?

It depends on the type of pool application. Although the warranty it comes with can stretch on for 20 to 30 years, when applied inground, it can have a life span of 6 to 12 years. When applied above ground, as it’s more exposed to the elements, it can shorten by 6 to 10 years.

Beaded / Hung Liners

backyard with lined pool, potted plantsA beaded / hung pool liner is a type of pool vinyl cover whose marketing value is a featured groove that’s run along the lip of the liner’s top edge. During the installation process, this small groove is actually snapped into a track called the beaded receiver.

This is on the inside edge at the top of the pool wall. This type of pool liner is known for its beautiful patterns and designs and this extends out to its tile trims as well as to its wall borders. 

Upsides and Downsides Of Beaded / Hung Liners

Here we share the advantages and disadvantages of beaded/hung pool liners


Beaded / hung pool liners are generally more attractive or aesthetically pleasing because the liner isn’t visible on the outside walls of the pool.

You can install or replace your beaded / hung pool liner without ever having to remove the top rails. This means that if you happen to have a deck over the top rails, there isn’t any need for you to take your deck apart just to get your pool liner changed.


They’re considerably more expensive compared to the rest of the other liner types. Some would argue that this would defeat the purpose of opting for a pool liner altogether – which is to save money.

During installation or replacement, you have to time it right. It needs to be on a hot day when the sun is out and where the liner material can get direct heat. This is for the purpose of stretching the material out a little bit to get the liner installed properly.

Although not a common occurrence, there have been occasions wherein the liner can pop out of the receiver.

This liner type isn’t recommended for pools that are located in areas that have generally cold weather. This is because it doesn’t have the extra material to handle the shrinkage during cold days.

You also have to consider that when your pool ices over, the weight on the top could further pool the material down and cause it to pop out of the receiver.

How Long Do Beaded / Hung Liners Last?

Beaded / hung pool liners are known to have a life span of 10-15 years specifically because they’re more commonly used for inground pools, which lessens the material’s exposure to harsh elements. Again, there can be a myriad of factors that can contribute to the lengthening or the shortening of this life span at the end of the day.

J-Hook Liners

pool with metal ladderA J-Hook pool liner is a type of vinyl pool liner that has an upside down “J” that hooks right on the top side of the pool wall. It functions very much like an overlap vinyl liner apart from this special feature.

This liner type is a little versatile because it can also be cut if you want to use it with a beaded receiver or coping strips. Because of its special hook, J-Hook liners can actually be used with pools without ever having a need for a bead receiver.

This J-shaped hook will take over the function of holding the liner in place once the pool is filled with water and prevent the material from slipping into the pool.

Opportunities and Challenges Of J-Hook Liners

Here we share the advantages and disadvantages of J-hook liners


J-Hook pool liners are incredibly easy to install as all it takes is for you to put the material on the pool floor, spread it out, and hook them up to the top rails.

It looks neat and well put together.

There is no trimming required as the material comes measured out and has a stretched appearance and is usually pulled taut by the J-Hooks installed at the top rails.

There is no need for a guide track as well so it makes for a much easier installation process.

Very easy to DIY and does not require a professional to install it correctly.


This pool liner type is recommended only for flat-bottomed pools so if you have an irregular pool type or a pool with varying ground levels, it will not be suitable for you to opt for a J-hook liner.

How Long Do J-Hook Liners Last?

A J-Hook liner isn’t known to last long so a good ballpark figure would be 2 to 5 years. It still all depends on how well you maintain the pool, what amount of element exposure it gets, and what the varying temperatures are in the area, and so on.

Uni-bead Liners

deck, pool, and white wallA uni-bead pool liner is oftentimes used for above ground pools. Its concept can be very similar to the concept of J-Hook pool liners. As a matter of fact, there are a lot of cases wherein you can actually buy a liner that’s both a J-Hook pool liner and a uni-bead pool liner.

It’s convertible, and you have all the freedom in the world to choose and pick one that will fit you and your pool needs best. In order to convert it into a uni-bead pool liner, you only need to add a small plastic piece to your J-Hook liner.

This piece can then effectively fit into a track. This track goes around your pool wall and is responsible for keeping your liner in place. In the event that you change your mind and you want to go back to the simpler concept of the J-Hook pool liner, you can simply remove this extra plastic part.

Like the J-Hook pool liner, the uni-bead pool liner is best valued and appreciated for how good it can make your pool look.

Wins and Losses Of Uni-bead Liners

Here we share the advantages and disadvantages of uni-bead pool liners


Like the J-Hook pool liner, the uni-bead pool liner is incredibly easy to install. You don’t need to hire out a professional just to make sure that the job is done correctly. This is actually something that you can do yourself even if you have little to no experience with pool liners.

It has a very attractive and neat appearance. Uni-bead liners are a good choice if you are going for luxury swimming pool designs.

It requires no trimming for the material. The material is usually tailor-fit and is “stretched” out.


Most uni-bead pool liners don’t come with their own guide tracks so this may be something that you’d have to purchase separately.

This type of pool liner is suitable only for flat-bottomed pools. It doesn’t work well for pools that have varying depths and it may be an issue with how the material is stretched out on the bead receiver.

How Long Do Uni-bead Liners Last?

Similar to J-Hook pool liners, uni-bead pool liners don’t really last for very long.  They have a shortened life span of 2 to 5 years compared to the other pool liner types that could stretch on for even 10 years or so.

Again, pool maintenance, element exposure, usage, and temperatures are all variables thrown into the mix of how long this pool liner is supposed to last.

Inground Vinyl Liner

pool with mosaic design inground linerAn inground vinyl liner, as the name suggests, is usually customized for specific inground swimming pool sizes and measurements. This is a liner that you would typically purchase alongside your pool purchase or pool construction.

How the material is held in place with this pool liner type is that the said material is actually pressed into the pool walls with the use of a reverse coping strip. This is a liner that can be very specific to your pool and doesn’t really leave much room for error or excesses in the material. What this means is that there isn’t any extra trim for you to worry about or deal with.

Benefits And Drawbacks Of Inground-Style Vinyl Liner

Here we share the advantages and disadvantages of inground vinyl pool liners.


Inground vinyl liners are very easy to install. It isn’t necessary for you to hire a specialist to get the job done. However, considering the fact that the material is taut or stretched out without a trim and usually comes along with the actual pool, it would be best for you to get your pool installers to put it on alongside your pool installation.

It has no trim so it looks far more attractive and you don’t have to deal with the challenge of having to hide it.

Inground vinyl liners are known to last longer to its other “more temporary” counterparts so the investment you make is sure to last you for years to come.


Because it’s custom fit for your specific pool, this vinyl liner can usually come at a premium. It’s the most expensive type of pool liner so far as you can’t just go with something store-bought. Your pool needs to be measured out and the liner needs to be manufactured according to its specifications.

You get less variety when it comes to the liner color and designs if you opt for an inground vinyl liner. You are typically offered just the classic or traditional colors.

How Long Do Inground-Type Vinyl Liners Last?

Inground vinyl liners enjoy a life span of 7 to 10 years. It depends on how you maintain the pool, what the weather conditions are in your area, and how often you use it.

Apart from the fact that this liner is custom fit for your specific pool, because the pool is inground, it also means that it has less exposure to the elements which may be one of the factors why inground vinyl liners tend to last longer.

How Do I Choose A Liner?

pool, and wood copingDecide on your pattern: One of the most important decisions you will ever make when choosing a pool liner is in the pattern. This is because this is the first thing you tend to see every time you get into the pool or even just look at it.

Select the thickness of your liner: A pool liner’s thickness comes second in importance to the material’s actual fit on your pool. You need to keep in mind that the life span of a pool liner doesn’t depend on how thick the material is but rather, on how good the fit is to the actual pool.

Always prioritize the pattern rather than the thickness when choosing a pool liner. Here are the varying pool liner thicknesses to choose from:

• 20/20 (in millimeters): 20 for the wall and 20 for the floor is the most-recommended pool liner thickness for most locations and environments. It works great with irregular pool shapes and other add-on features that the pool might have.

• 27/20 (in millimeters): 27 for the floor and 20 for the wall. This is recommended if you want to add some more strength to your pool walls. This bears the most weight, after all. If you happen to be in an area that tends to get extended periods of freezing weather a lot, this pool liner thickness can be a great recommendation. 

• 27/27 (in millimeters): 27 for the wall and 27 for the floor. This is a pool liner thickness that’s recommended for extreme weather and conditions. If you have issues such as having rough surfaces on your pool floor or having constant freezing weather and your liner fails you every now and then, this may be the best pool liner thickness to go for.

Check out your liner options: This is where your sense of creativity and personal style comes in. This is one of the most enjoyable things about vinyl liner pools. They offer the most flexibility in options compared to any other type of pool construction out there.

Here are some liner options to consider:

Texture of the material

No-tile option

Mix & Match (patterns)

Liners over stairs and benches

Is A Thicker Liner Better?

lined pool without water, mosaic designThe thickness of your pool liner all boils down to a matter of preference so the initial answer to this is no. However, when you consider the conditions the pool is placed in, there may be instances wherein yes, a thicker pool liner might actually be better.

Here are a few scenarios that would benefit from a thicker swimming pool liner:

Rough spots in the pool floor that might snag at the liner material

Freezing conditions in your area that might put extra weight at the top when the pool ices over, causing the liner in your pool wall to collapse if it isn’t thick enough.

How Long Do Liners Last?

Or you may have extreme weather conditions. You may have issues with proper maintenance and tend to neglect it. There are so many things that could factor into the life span of how long a pool liner is supposed to last.

And then, of course, is the issue of the type of liner you have and we’ve detailed each of them above already.  But in general, 10 to 15 years is a good range.

How Does A Dark Liner Make Pool Water Warmer?

oval pool with landscape viewYes. Dark liners do make the pool water warmer. This is all because of its reflective properties. When a liner is dark, it limits the water surface’s ability to reflect light away from the surface because instead, it absorbs it (because of the color). This increases the pool water’s temperature, making it warmer, and making it much nicer to soak in.

Will Salt Damage A Liner?

pool with blue lining and metal railsYes. Salt is known for its extremely corrosive qualities and it can definitely wreak havoc on your pool liner, especially if not kept in check. Over time, salt can wear down the lining of your pool liner. This, in turn, can result in tears or holes in the material.

The moment that your liner gets tears, you have either the option to patch it up with some extra material if the holes are fairly small but if they turn out to be beyond saving already, you might not have any other choice than to replace the entire pool liner.

If a typical pool liner has a life span of 10- 15 areas, under saltwater, it may shorten it to 5 to 9 years. Read more about saltwater vs chlorine pools here.

What Color Liner Is Safest?

rectangular pool with garden shrubberyDeep blue. This happens to be the safest color and, it turns out, is also fairly convenient and efficient. More than that, this is the color that people associate the most with swimming pools.

Probably because water is generally related to the color blue. You need to keep in mind that the color of your liner will set the stage when it comes to the overall feel and effect of your pool. 

Another reason why blue is the safest pool liner color to go with is that deep blue actually absorbs sunlight. This can help tremendously in warming your pool water up.

However, over time and with its exposure to chemicals, its deepness could fade out. You also need to factor in its extreme exposure to the sun. And this leads us to our second safest color, which is light blue.

A light blue liner will not show signs of degradation via bleaching and fading out as much as the dark blue will. This is why this color comes in second as a safe pool liner color. Other similarly safe color choices are vibrant blue or aquamarine.

Is It Better To Have A Dark Or Light Liner?

It’s always better to have a darker-colored pool liner. Darker colored liners are great at absorbing heat because it minimizes the water’s ability to reflect the heat and sun rays back into the atmosphere. Instead, it absorbs into the water, effectively warming it up.

A lighter-colored liner, on the other hand, may radiate the light and heat out, resulting in an energy loss and ultimately, cooler pool water temperatures.

Dark pool liners are also great at hiding dirt or debris in the pool. It also hides imperfections such as scratches and mars better than the lighter colored liners can. It makes it less easily noticed.

If you are thinking about putting in a pool at your home you can use one of the pool design software programs to try out different colors to see which look you prefer best.

Wild animals: Wild animals are notorious for getting themselves trapped in your pool and they end up damaging the liner in their attempt to claw themselves out.  This is common for homes that happen to be in rural areas.

To minimize this, make it a point to leave your pool covered when not in use. Don’t leave food items in the pool area, and remove any stairs or ladders that might aid the wild animals in entering your pool.

Improper swimwear: Change into a bathing suit or trunks whenever you get into the pool. Make sure that everybody else will observe these rules as well.

Miscellaneous objects from regular clothing such as buttons, zippers, clasps, and the like can end up damaging your liner if they accidentally rub up against it.
