Experience the same instant drying power as our Bath Stone™ Mat, now in double the size with a customizable blueprint. Patent-pending design has enabled us to create the largest diatomaceous earth bath mat on the market. Made with Diomat™ technology, this mat feels similar to a durable ceramic material and stays at room temperature (no cold toes please!). 

Unlike traditional bath mats that absorb moisture and generate bacteria, the Large Bath Stone is designed to instantly remove water, actually helping prevent mold. Customize your layout with 4 adjustable tiles to fit any space. The Large Bath Stone can be arranged in a rectangle, straight line, U-shape, and more.
