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

Dorai products are made from diatomaceous earth which is a naturally occurring mineral composed of fossilized aquatic organisms. For example, our Dorai Bath Stone combines diatomaceous earth with recycled paper. This creates a sustainable, non-toxic, and highly effective drying solution for your bathrooms.

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

Yes, a diatomaceous earth drying mat is safe. Made from natural, non-toxic diatomaceous earth, these mats offer a clean and healthy drying solution. Our diatomaceous earth Bath Stone is designed to be environmentally friendly and safe for everyday use to ensure that your bathroom remains free from harmful bacteria and mold.

Our products use 100% food grade diatomaceous earth. Our Diomat® material passes FDA food safe testing and Prop 65 testing. Prop 65 testing means our products are asbestos and lead free.

In a diatomaceous earth bath mat, water is quickly absorbed into the millions of microscopic pores its material has. This rapid absorption allows the Dorai Bath Stone to hold up to 150% of its weight in water, which then evaporates quickly. The pores also keep the surface dry and prevent water from pooling on your bathroom floor.

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.

Yes, stone bath mats like the Dorai Bath Stone are highly sanitary. These mats help prevent the growth of mold and bacteria by quickly absorbing and evaporating moisture. The antimicrobial properties of a diatomaceous earth mat ensure a clean and safe bathroom environment.

Stone mats made from diatomaceous earth, such as the Dorai Bath Stone, are designed to prevent mold growth. The quick-drying properties of our diatomaceous earth bath mat reduce the chances of mold formation. Proper care and maintenance further help in preventing mold.

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 airflow 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 (by using the non-slip pad included in the Bath Stone™ mat), 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 sandpaper to gently rub off any marks. We recommend doing this in a well-ventilated area. For more extreme stains, small amounts of bleach or hydrogen peroxide will do the trick.

We elect not to add dyes or additional substances to the Diatomaceous Earth compound and instead embrace the natural color. Given the material’s lighter tone and porous nature  there is a risk of staining with dirt or darker liquids. We suggest only stepping on your Bath Stone™ mats with clean feet and only placing clean dishes on your Dorai Dish Pad to prevent staining. 

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. We recommend doing this in a well-ventilated area. For more extreme stains, applying small amounts of diluted bleach or hydrogen peroxide should do the trick.

Due to its porous nature, marble and other natural stones are sensitive and prone to discoloration or staining, especially when not sealed. We do not guarantee Dorai products like our quick-drying bath mats on these surfaces. For more information click here.

Diatomaceous Earth is a white algae substance that is broken down into small pieces, so white spots occur naturally in the production process. Some larger pieces remain during this process. We hope you appreciate the natural substances and understand that some white algae pieces will remain visible on the dark surface.

Glad you asked - we hope this is the last bath mat you ever need to buy. If you’re wondering how to clean your diatomaceous earth bath mat, you can find the care instructions enclosed in your packaging and in our FAQs. 

Whether you’ve bought the Rain or Zen Bath Stone™ Mat, Dorai Bath Stone™ mats  are meant to be durable. But on rare occasions, our diatomaceous earth Bath Stones™  can break with enough force or weight. To prevent this, we advise always having the foam pad in place between the floor and the mat. Be sure to check out our guarantees and reach out to customer service if your stone breaks within the warranty period, you can contact customer support here.

This is to be placed under your Dorai Bath Stone to provide a non-slip base, and to help disperse the weight evenly when stepping on the mat. Place it evenly between the floor and your Bath Stone.

1. Lay the rubber, non-slip base on the ground with the knobs and Dorai logo facing up.

2. Snap the firm plastic connectors into the cutout sections of the rubber base to hold the pieces together.

3. Place your Bath Stone™ tile on top of each base piece, making sure the knobs of the base align with the holes on the back of each Bath Stone™ tile.
