Diatomite

Diatomite is a naturally porous mineral formed from fossilised microscopic algae called diatoms. Its fine internal structure draws surface moisture into tiny pores and releases it again as the material dries.

Diatomite

Properties

What it is. The material behaves differently from a textile bath mat. It does not hold water in a pile; it spreads moisture through a hard mineral surface so evaporation can happen quickly.

Why we choose it. We choose diatomite where a dry, low-profile bathroom surface is more useful than fabric: beside a basin, shower or bath.

Look and feel. Dry, matte and stone-like, with a fine mineral touch and a cool surface.

Where it appears. Bath mats and selected bathroom accessories.

Natural character. Light powdering, tonal variation and gradual surface patina can occur. The material may carry small pores that are natural to its structure.

Care

Use on a flat surface, allow both sides to air dry and clean only as directed. Fine sanding is appropriate only where the product instructions approve it.

Good to know. Diatomite is absorbent but can crack if dropped, bent or placed on an uneven floor. It should never be soaked or stored damp.

Diatomite FAQs

Why has my diatomite bath mat stopped absorbing water?

The stone’s pores can clog with soap residue and skin oils over time, blocking the capillary action that pulls water in. Light sanding with 400 grit paper reopens the surface.

Can a diatomite mat be washed like a normal bath mat?

No, and this is the one rule that matters: diatomite is never machine washed. Stand it up or hang it to air between uses instead.
