Diatomaceous earth.
A mineral built
for water.
Every MEGEM mat is composed of a single material — diatomaceous earth. Not a composite, not a coating. A solid mineral surface with properties that no fabric, foam, or synthetic material can replicate.
Diatomaceous earth is a sedimentary rock formed over millions of years from the fossilised remains of diatoms — microscopic single-celled algae. When mined and processed, it becomes a lightweight, highly porous mineral with a structure that is invisible to the eye but exceptional in performance. The same material has been used in filtration, food preservation, and construction for decades.
We chose diatomaceous earth because it solves the bathroom mat problem permanently. It absorbs water on contact rather than spreading it. It evaporates without mechanical assistance. It does not retain moisture between uses, which means it cannot become a host for mould or bacteria. It does not degrade with use. It does not require a replacement cycle. It is the correct material for the task.
Designed by
mineral structure.
Instant absorption
The porous surface draws water inward on first contact. No pooling, no spread, no delay. Step onto the mat and the moisture is gone from the surface immediately — absorbed into the mineral structure below.
Rapid evaporation
Micro-channels within the material disperse absorbed water laterally and release it as vapour under ambient conditions. The surface returns to dry within minutes — without wringing, hanging, or ventilation.
No residual dampness
Stone does not retain moisture between uses. There is no damp layer, no saturated core, no microbial environment. The mat is dry before your next use — every time, without maintenance.
Formed over millions of years.
Diatoms are among the oldest organisms on earth. When they die, their silica shells sink and accumulate on lake and ocean beds — compressing over geological time into the soft, chalky rock we mine today. The result is a material that is simultaneously ancient and precise. Each MEGEM mat is cut from a single slab, sanded to a consistent surface, and finished without chemical coatings or additives. What you receive is the material itself — nothing added, nothing removed.
