Both urine and leaking water can cause slippery surfaces and foul odors. Urine can often, in time, cause tile floors to erode, theses restroom mats have an anti-microbial agent that helps prevent any damage from occurring. As the fibers get wet the anti-microbial is released and the odor stops from starting. Even though this floor mat absorbs and breaks down the urine, the surface of the mat remains dry.
