If you have questions about LinerWorld, our pool liners, or our other pool maintenance products and accessories, you’ve definitely come to the right place. We’ve put together some of the top questions we get from customers just like you. Not seeing what you need? Don’t hesitate to contact us!
What are your pool liners made out of?
All of our above ground pool liners are made of high-quality vinyl. Vinyl is durable, flexible, and resistant to UV rays, making it a great option for your above ground pool.
What is the difference between an overlap pool liner and a beaded pool liner?
Great question! Here’s a quick overview:
- Overlap pool liners go over the side of your pool wall and are held on by coping strips.
- Beaded pool liners are fed into a bead receiver (which is installed on the inside of your pool wall).
Check out our handy guide to learn more about overlap and beaded pool liners.
What size pool liners do you offer?
We have a variety of different sizes to meet your needs.
For round pools, we offer pool liners ranging from 12’ to 32’.
For oval pools, we offer pool liner sizes between 12'x18' and 21'x41'
For rectangular pools, we stock pool liner sizes between 12'x20' and 16'x32'
If I don’t see my pool size as an option for a liner, can I buy the next size up and use that? Will it fit properly?
What is the thickness of your round pool liners?
All our above ground pool liners are 25 gauge.
Do you have above ground pool liners for deep ends?
Our expandable pool liners are designed to expand easily into deep-end swimming pools. You can also use them in flat-bottomed round pools.
Do you sell J-Hook, U-Bead, or Unibead liners?
While we do not sell these specific liner types, we recommend purchasing a bead receiver along with one of our standard beaded pool liners as a superior alternative to J-Hook, U-Bead, or Unibead liners.
Do you sell Intex liners? What liner will work for my Intex-style pool?
We offer relining kits for Intex pools. These kits are designed for pop-up style pools (also known as tube frame pools) with frames made of metal or PVC tubes and a liner with pockets for the tubes to slide through.
Our relining kits work with frames with round tubes along the top ledge of the frame. such as Intex, Summer Waves (excluding Summer Waves Elite versions), Coleman, and other standard tube frame pools.
Our kits DO NOT work with tube frame pools that have oval or flat-topped poles along the top ledge of the pool frame, such as the Summer Waves Elite versions.
Do you sell in-ground pool liners?
No, we focus on above ground pool liners. However, we do sell in-ground pool covers.
Can you make custom pool liners?
We are not offering custom or special order above ground pool liners at this time. Check out our custom liner page to learn more and get on our list for future orders.
How long do your above ground pool liners last?
A well-maintained vinyl pool liner can last 10-15 years or more. However, factors such as proper maintenance, installation, and frequency of use can all impact the lifespan of your liner.
Are dark or light pool liners better?
It depends! We have a variety of light and dark-colored pool liners with unique patterns and designs. Check out our blog for more resources about dark vs. light pool liners and picking the right pool liner for your backyard.
