The Diomat Difference

Dorai combines the rapid drying, mold-fighting
power of diatomaceous earth with
thoughtfully designed home solutions.

Talk Science to Me


Diatomaceous earth, or grass of the sea, is a naturally occurring mineral that is made from the fossilized remains of tiny aquatic organisms.


Our products are made using Diomat technology. When moisture hits the surface, the material attracts and binds bacteria and parasites, causing them to dry out and die.


Water rapidly evaporates from the product through millions of pores. Say bye to bacteria and mold!


Welcome to your modern home! Magical, eco-chic products that keep your home clean and looking great.

"Dries quick and leaves no trace of moisture."

Love Notes

Love it-getting more

I purchased one may and love it. Had it in my bathroom but then decided it was more useful by the tub where the kids splash! Now I’m buying more and 100% regret not buying the family pack in the first place. I wanted to try it first but I could have saved a bunch too. And my daughter wants pink. So here we go. I’m like Oprah you get a mat and you get a mat.

Perfect for germaphobes

At first the sound of a firm bath mat sounded peculiar, but learning about the antimicrobial Dorai materials, I knew I had to try it, because I am a bit of a germaphobe....I am so glad I did! I love the style and the cover provides that spot of softness that my toes crave. I feel so much better knowing that I am stepping out of the shower onto a more sanitary surface and my bathroom is now and forever free of that "time to wash your bath mat" smell! I can't wait to see what products the Dorai team creates next because I am a fan!

Lovely and Practical

Our stone coasters arrived approx 2 weeks ago and have been getting some heavy use ever since. Our young nephew loves to drip water onto them to watch it disappear and my husband is remembering to use a coaster (not sure how Dorai managed that one, but I’ll take it!). The stone holds everything from coffee mugs to wine glasses to water glasses really well, ie, nothing slides around. They arrived beautifully packaged and fit in with our decor really well. "


How do you pronounce Dorai?

Great question! Dorai is pronounced DOR - eye. From the Japanese word for Dorai, it symbolizes a natural and dry home.

What is Diatomaceous earth?

Diatomaceous earth, or grass of the sea, is a naturally occurring mineral that is made from the fossilized remains of tiny aquatic organisms.

How else is DE used?

DE (Diatomaceous Earth) has various uses. It can be found in toothpaste, dietary supplements, skin scrubs, pet nutrition products, and more. This versatile powder offers numerous benefits, including support for teeth and skin health, improved digestion, and boosted immune function. A necessity in the home, it’s used in rodent sprays, non-toxic cleaners, and deodorizers. DE is an excellent chemical-free alternative to so many common household and hygiene products.

Where does Dorai store the water?

The Dorai bath mat doesn’t “store” water. It rapidly evaporates the water by exposing it to greater surface area through millions of pores.

What makes Diatomaceous Earth antimicrobial and are Dorai products too?

Diatomaceous Earth is antimicrobial by its physical properties not through the use of any chemicals or toxins. In its raw state the material attracts and binds bacteria and parasites, causing them to dry out and die. When compressed into boards it still rapidly evaporates to help prevent mold, but doesn't hold the same antimicrobial properties as the raw material.

How do I clean my Dorai Diomat products?

Unlike many bath mats or dish racks, the Dorai Diomat utilizes rapid drying that dissipates moisture and helps to prevent mold. However mold is a pesky invader, while Dorai's Diomat can hold up to 150% of its weight in water, it needs adequate air flow to rapidly dry. If your Dorai products are constantly saturated and not able to properly dry out, they can eventually grow mold (at a much slower rate than traditional products). To prevent this be sure your products are slightly elevated from the surface (as they have been designed to be), and let them fully dry out between uses. When overly saturated, prop them up against a wall and when they return to their original light color they are ready to go. Similar to light colored towels or sheets, darker liquids or self tanners can cause some staining if absorbed into the mat. Lighter liquids will not typically stain your mat. In the event that your mat gets stained, it can be cleaned in two ways. For light stains or scuffs, use the included sand paper to gently rub off any marks. For more extreme stains, small amounts of bleach or hydrogen peroxide will do the trick.

Can my mat get stained?

We elect not to add dyes or additional substances to the Diatomaceous Earth compound and instead embrace the natural color. Given the lighter tone of the material, there is a risk of staining with dirt or darker liquids. If you spill on it, first, try to dab up any excess liquid before it’s absorbed. For mild stains or scuffs, get your product damp and use sandpaper (150 grit or similar) to gently ‘wet sand’ off any marks. For more extreme stains, applying small amounts of diluted bleach or hydrogen peroxide should do the trick.
