Diatomaceous earth is a naturally occurring mineral valued for its fast-drying, highly absorbent properties. Free from harmful chemicals, its porous structure draws in moisture on contact and encourages rapid evaporation, reducing lingering dampness and creating an environment less conducive to mold, mildew, and odors. The result is a cleaner, drier surface that is easy to maintain.

Step 1

Start by wetting the stone surface to loosen any debris or residue. Spray it evenly with a mild, liquid-based soap or gentle household cleaner.

Step 2

Use an abrasive sponge or cleaning brush to scrub the surface in small circular motions. Focus on any areas with visible buildup or discoloration. Rinse thoroughly with clean water, and repeat as needed until the surface looks refreshed and free of residue.

Step 3

Repeat the same cleaning process with the rubber bases. Scrub them using soap and water to remove any buildup or residue, then let them dry completely.

Step 4

For deeper stains, dampen the affected area and sand it lightly with a medium-grit sandpaper in a well-ventilated space. Wipe away dust and residue, then allow the stone to dry fully before using it again. This ensures it maintains its quick-drying, mold-resistant performance.

So much better than traditional cloth bathmats

This bathmat is awesome. It dries incredibly quickly, it looks great, and it’s much more sanitary than a traditional cloth bathmat.

The only downside is that it’s a bit of a magnet for pet hair or hair, but hopefully that will get better over time.

It’s well worth the price. The customer support is also amazing and friendly.

I highly recommend this product.

Favorite thing

It’s my favorite thing in my bathroom. There’s something incredibly satisfying about how this feels under your feet when you step out of the shower/bath that is unexplainable you try it. And you have the ease of mind it won’t retain water and get dingy like any mat made of cloth because by the time your finished you bathroom routine it’s dry. Spend the money - it’s absolutely worth it

Much needed product!

We have a European-style bathroom with a glass shower panel that only covers half of the tub, so water was constantly splashing onto the floor and soaking our bath rug. This mat turned out to be the perfect solution. It absorbs the water quickly, keeps the floor dry, and dries fast, helping prevent the damp, mold-prone mess we were dealing with before. It has made a noticeable difference and has held up really well!

In love with this bath mat!

The quality is exquisite and its operation is excellent! I no longer have to contend with wet bath rugs. The wetness is gone in no time after stepping out of the shower. I simply love it!

As nice as I’ve always imagined.

I’ve long been familiar with the benefits of diatomaceous earth. For too long, I have wanted to get an item from Dorai. Now that I finally have, I wish I hadn’t waited so long. It’s a wonderful product. I love my bathmat.

Functional and aesthetically pleasing

I have these mats in every bathroom of my house and also have the dish drainer and pad. The mats are beautiful and work as described. I will never use rugs in the bathroom again as these are beautiful to look at and more hygienic. If you’re on the fence, absolutely buy these for your space.

Will never buy from this company again. Would not recommend any of their products

Extremely disappointed with this company. They sent me the wrong order, charged me for an extra bath mat that I never ordered, and then expected me to pay return shipping to fix their mistake. I was also expected to haul a very heavy package to the post office because of an error they made. Customer service has been slow to respond and has taken no accountability for the situation. For a premium-priced product, I expected premium customer service. Instead, I was left dealing with the inconvenience and additional costs of their mistake. I will not be purchasing from Dorai again and would not recommend this company to others.

Love the absorbency but…

Should have gone with darker color because I don’t love the faint marks of feet, dust, pet hair, etc.

Love the Stone, don’t love the maintenance

These stones are legitimately awesome. I love that they don’t hold bacteria and they really absorb. I don’t love the maintenance required by the light color - I have just added yet another task to my bathroom cleaning to keep the stone clean and bright which is a bit irritating.

Love it!

We wanted the bath stone because of how quickly it would dry, we were sick of bath mats being wet for soooo long. This now dries so quickly and doesnt drive me nuts anymore when my husband steps out of the shower soaking wet. We love our new large stone and especially how we could choose how to arrange the four pieces because our shower is long and the bathroom is narrow, so we created a long line of the four pieces. One of the pieces however is just a little wobbly because of a slightly uneven floor, I just wish there was a base that had more allowance for that to level out the pieces.

Amazing purchase

Our bathroom gets so cold during the winter and our old bathmat was taking forever to dry. It was always a little damp and would get moldy- just wasnt cutting it anymore. We have loved the large bath stone! It is crazy how quickly it dries and it looks so chic in our bathroom. I was concerned about the stone getting super cold but it absolutely does not. It was also soooo easy to put together 10/10.
