45 mil  FISH-SAFE pond liner is the industry standard in water gardens and koi ponds! We stock fish-safe liner from three US-based manufacturers: Firestone PondGuard Brand, Duraliner Brand, and Anjon LifeGuard Brand.  All three brands have been widely used for over 25 years with thousands of pond installations. Your Fish-safe liner may be any one of these brands depending on our availability at the time your order is shipped!

This sturdy, long lasting, super flexible rubber liner is fish, pet, livestock and wildlife safe.

The liner is much easier to install than a pre-formed pond and has a minimum 20 year Manufacturer warranty!

While this liner is made from the same material (EPDM) as some roofing liner, FISH-Safe EPDM liner is guaranteed to use no treatments during the manufacturing process that could potentially harm fish or be toxic in any way.

Shipping Restrictions: Sizes 400 square feet and larger can only be shipped to the 48 continental United States.

Pond Liner CALCULATOR

Enter the largest measurement for each dimension. If you're digging a pond 10 feet wide on average, but there is one section that measures 12 feet wide, please use 12 feet as the width.

Liner is manufactured in widths divisible by 5. Therefore, our liner calculator always rounds up the width to the nearest multiple of five.
