The Diatomite mat has taken many by storm by virtue of its functionality and practicality. Made from Diatomite, a soft sedimentary rock known for its extreme water absorbent & anti-mold properties, it makes the perfect ingredient for a bath mat. The absorption barely takes 1 second, slurping up the water from your feet like a thirsty camel. All it takes is approximately 1 minute for the mat to dry up and go back to its original state. Easy to store away and clean. Do note that as the Diatomite rock is made from natural fossilized algae remains, there may be white or dark spots on the mat due to the natural compounds and is not an issue of quality.
