This KOHLER® Rely shower base provides the reassurance of a low step-over threshold for easy access to your shower. A water containment bead along the threshold serves to prevent water escaping onto the bathroom floor. Durable acrylic construction eliminates any flex when stepping into the shower and allows for quick, easy installations. The Rely 48" x 42" acrylic shower base is designed to work with any shower wall application and pairs perfectly with the KOHLER® Choreograph® shower wall collection. Coordinate it with Choreograph walls and accessories to complete your personalized shower installation.
