We've had our pool for 12 years, and it is time to replace the vinyl liner. We have a family member who worked in the pool industry for years, 2 of which he spent replacing liners. So we're not looking to hire a pool dealer or company to come do the work. We just need a place to buy a quality liner that will last as long (or longer) as the previous one did.

Are there any places I should avoid? Or more importantly, have you had good luck with any online vendors/suppliers that you would recommend?

Ours is an in-ground, 18' x 36' pool with an 8' deep end and fiberglass stairs at the shallow end.

Much appreciate any advice or suggestions you have.
