CastelloUSA Diatomite Bath Mat

Unlike fabric mats that hold moisture and require frequent washing, this diatomite mat absorbs water instantly and dries in seconds. It is a rigid, mineral-based surface that prevents puddles and resists mold and mildew naturally.

The mat is designed with a stable, slatted surface that provides traction. However, because it is a hard, stone-like material, it does not have the same grip as a rubber-backed fabric rug, so it is best placed on a flat, even bathroom floor.

Maintenance is minimal. Because it is naturally resistant to mold and odors, you do not need to machine wash it. If it gets dusty or stained, simply wipe it down with a damp cloth or lightly sand the surface with the included sandpaper to restore its absorbency.

With a slim profile of just 0.4 inches, this mat is designed to fit under most standard bathroom doors that have a typical clearance gap. Its low-profile design ensures it won't obstruct door movement.

No, this mat is intended for use outside the shower or tub on a dry floor. It is not designed to be submerged in water or used as a non-slip surface inside a shower stall.
