Latham vinyl liners are made from the finest quality vinyl available and are treated with a special fungicide to inhibit bacterial growth. Latham liners are easy to clean, smooth to the touch and as close to maintenance free as you can get. Latham vinyl liners are engineered and produced in a climate controlled setting for consistent quality. Computer aided design (CAD) insures all liners are designed to exact dimensions and cut to specification. Each liner is sealed together using radio frequency controlled machines and then inspected and boxed with a consumer information package.
