The Post-Pour Pool Cover for Pools In Pools is a custom automatic safety cover system engineered for retrofit applications. Designed for nested pools where a spa or smaller pool is built inside a larger one, it offers a seamless, integrated solution after the concrete deck has already been poured. With precision-fit customization and walk-on lid options, it blends functionality with modern aesthetics while enhancing safety and energy efficiency. Built to accommodate complex shapes and existing deck structures, this system is ideal for upgrading established pool-in-pool installations.
