Which pool liner thickness should you choose?

Oftentimes people ask us which liner material is “better:” the 20 mil or the 27 mil?

In reality, there is no “better” liner.  The most important choice is not the thickness of the material, but the liner pattern that you choose.

Choose the vinyl liner pattern that you like the best.  If it comes in 27 mil at no extra charge, take it, but don’t pay extra for it.  You shouldn’t pass on your first pattern choice just to get the thicker material.  In our opinion, there is no meaningful advantage to thicker material.  There is no difference in wear, durability, longevity or warranty.

Liners fail for two reasons.  The ink fades or the material dry rots above the waterline.  Thicker material solves neither of these problems.

Most importantly, choose a vinyl liner pattern that speaks to you.  You are going to be looking at that pattern in your backyard for at least the next seven years.  Ultimately, the pattern you choose should outweigh the thickness of your liner material.  It is what you think looks the best that matters.

Hi,
We live in sunny San Diego. Our in ground liner is being pulled down in the corners and one of the sides.
We have patched up the splitting spots.
How can we prevent more damage. The water seems to be pulling the pool down.

Thank You Juanita
