The Pattern/Template Spa Cover is designed for hot tubs that don’t have standard dimensions or shapes. If your spa has rounded corners, unusual curves, built-in speakers, cutouts, or any irregular features, a standard-sized cover won’t provide an effective seal. In these cases, a physical pattern or template is required to ensure a precise fit. The customer creates and mails a template, usually made from cardboard or plastic sheeting that outlines the spa’s shape. This template is then used to manufacture a custom hard spa cover that fits tightly, helping prevent heat loss, weather damage, and debris accumulation.
