Shower mats are a great safety feature to ensure you don't slip in the soapy water. Tiles get very slippery when wet and soapy, especially if they aren't as clean as they should be. Putting a shower mat down will keep you safe and secure in the shower. Our mats have great grips on the bottom so they don't slide around on the ground. The mats are made out of white vinyl and they have small perforations to enable draining so the water doesn't pool on the surface. Take advantage of our free shipping on this great product.
