What is the difference between 20 Mil and 27 Mil?

20 Mil: The industry standard. It offers excellent durability and flexibility, making it easier to install.

27 Mil: Thicker and heavier. It provides extra protection against punctures (dog claws, energetic kids).

27/20 Mil (Hybrid): The best of both worlds. This option features 27 Mil Walls for extra protection against sun and abrasion, paired with a 20 Mil Floor to keep the liner flexible and easier to install.
What type of bead do I need?

Most inground pools use Standard Bead, but we also support specialty beads:

  • Standard Bead: Fits into a track on the pool wall.
  • Esther Williams / Johnny Weissmuller: Used for specific aluminum-wall pools (usually with a larger bead).
  • Wilkes Bead: A specific hook-style bead.
  • Not sure? Send us a close-up photo of your old liner's edge, and we will identify it for you.
How much does shipping cost?

It is 100% Free. We offer free standard ground shipping on all orders over $74.99. Since InGround pool liners meet this threshold, you won't pay a dime for delivery within the contiguous U.S.
