Pool liner thickness is measured by gauge, with higher gauge numbers indicating a thicker and more durable liner. A 20 gauge liner is the standard option and offers good quality and performance at a lower cost.
A 30 gauge liner is thicker than a 20 gauge liner and provides added strength and durability. The increased thickness helps resist punctures and everyday wear, which can extend the life of the liner. For this reason, a 30 gauge liner is the better option for a long-term investment.
