The Self-drying Soap Dish is made of Diatomite (fossilized algae), a 100% renewable and plant-based material. It's water-absorbent and quick-drying which makes it ideal for places where water can accumulate without frequent clean-up. 
 
To pair with solid dish soap bars, which have been widely loved in the zero waste living community, Plantish spent months finding a material that is both safe and effective. The soap tray's finish is similar to concrete but has draining holes and pathways to ensure soap and shampoo bars stay dry and your countertops and ledges clean from soap residue.
