Some mats tend to stay wet long after they’ve been used, causing them to feel squishy and uncomfortable under your feet.With stone mats, soaked bathmats are a thing of the past! Our mat contains diatomite, a natural type of rock that absorbs water and dries up almost instantly thanks to its micropores. Moisture is also unlikely to accumulate in this material, so you don’t have to worry about bad odors after constant use.
