The CKB 60 in. L x 32 in. W slate gray shower base is a single threshold shower pan designed for easy installation in a shower enclosure. It features an integrated flange on three sides, which helps to create a watertight seal between the shower base and the surrounding walls. The integrated flange simplifies the installation process and helps prevent water leakage. The shower base is made of fiberglass reinforced material, which adds strength and durability to the product. This reinforcement ensures that the base can withstand the weight and pressure exerted during regular use. The center drain hole in the shower base means that the drain is positioned in the middle of the base. This design allows for efficient drainage of water from the shower. The base design includes a strong and secure structural support, providing stability and longevity to the shower base.
