for the irritating product photo. Unlike the photo is the only mat UNI black and has not been supplied in different gray or off-white tones. Fits anyway. The nubs on the bottom are numerous and in the pretty old shower tray for my elderly in-law Lord himself makes the part well. Even after several uses firmly on the ground. As with all mats man must however make the effort to withdraw the part and cleaned regularly, otherwise ugly dirty areas could remain in the shower tray.
