    In-ground pool liners are an essential piece to having the perfect pool. And often times, once you install it, the liner is there for a good, long time thanks to the permanent decking around the pool. So make your choice carefully and keep several things in mind.

    First, you want the in-ground pool liner that you love the looks of, one that will compliment your outdoor space and make you happy when you look at it and swim in it. Then you’ll want to pick out the gauge, or thickness, of the vinyl itself. If you live in a harsh climate where it freezes a lot in the winter and real hot in the summer, the thicker the better. One thing to keep in mind are liner accessories like a roll of in-ground pool wall foam that provides a smooth wall back and prevents your liner from wearing down from rust or corrosion.

    You can also choose to install your liner over stairs for a fully integrated, solid look. Just remember, that in-ground pool liners are not the easiest to replace, so choose carefully and get want you want. In the Swim representatives are always available to help as well.

      My New Liner
      I have a large double Roman in ground pool. I chose this company after a lot of research. I mean think about it. It's a lot of work and when it is done, you want it perfect. I called and I have to say. I was treated like I really meant something. We talked to each other many times on the phone and they showed me how to measure everything, plus how to build my steps with rolled foam so they would come out perfect. My new liner is in and I want everyone to know that it's perfect. Not even one ... read more wrinkle in it. Wish I could show a picture, because it is beautiful. So Thank y'all. One very happy customer !!!

      Love the design!
      I needed a new pool liner and the local pool dealers were charging about $450 for a new liner. The price for this was much more affordable. I am happy that I made this purchase and saved so much money.

      Just installed- will never by another overlapping liner- this honestly makes a new liner go in super smooth! Make sure you do this on a sunny day so your liner has time to stretch out while filling!

      Pool Liner
      I purchased my pool liner and I was impressed on how quickly it was at my house. I was very concerned on installing such a large liner but with a couple of extra hands it went in in just about in hour. Jhook liner is the way to go!!!

      I hesitated to replace my old tile bordered liner with a with this boulder swirl pattern. All I can say is the image doesn't do it justice. I love how it looks! Very dark blue in the border - nice change!

      Very easy to install
      The house we bought had an above ground pool. This winter our cover blew off and a stick ripped the liner. To save money we decided to install a new liner ourselves. After shopping around we were told about this website by a relative. It's about the same price as the store but it was better quality and with the fast free shipping and the customer service they have, we decided to order from It did arrive quickly and it's made very well. We looked up videos of how to put in a new ... read more liner and away we went. It was very easy to replace the old liner and the quality is definitely good. I would definitely recommend!!

      Product was as specified and as a matter of fact better than I thought good quality but the shipping was the best part 2 days later it was here and I was up and running, strongly recommend this company to anyone I got my liner 300 cheaper than the local pool store wanted.

      Pool looks beautiful!
      We recently ordered the Boulder Swirl pool liner. It was easy to install and looks great. We are very happy with the quick service (it come in just a few days) and the quality and look of the product. Thank you. We'll really enjoy our beautiful pool this summer!

      We bought a new liner, this was our second liner in the past 12 years. With this new liner we had to use a utility knife and cut the top of the liner for it to work properly. Once we figured out exactly what to do, it worked out fine. We did end up with a small cut in the liner, I guess it happened while cutting the lip. I just thought I was reading the directions wrong. Seems strange to cut a liner??
