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.

Frequently Asked Questions

Our Large Bath Stone™ Mat introduces a blend of luxury and function into your bathroom. Unlike traditional fabric mats that retain moisture and foster bacteria growth, a large stone bath mat works differently by leveraging the natural absorbency of diatomaceous earth. 

This not only ensures instant drying but also significantly reduces the risk of mold and mildew. Its sleek design and customizable layout offer an aesthetic upgrade, making it a sophisticated choice for those who prioritize cleanliness without compromising on style. Also, the large bath mat’s innovative flat-lay technology keeps it flush with your floor which makes it safe and easy to use.

Our Dual Bath Stone™ Mat stands out thanks to its quick evaporation technology that keeps both feet and floors dry. This feature is essential for a more mold-resistant bath mat that ensures a hygienic bathroom. 

Furthermore, the adjustable and lay-flat design of our mat provides enhanced stability and prevents water pooling, which is common in less hygienic mats. If cleanliness is at the top of your priority list, choosing a bath mat that’s more mold resistant like ours ensures both functionality and peace of mind in maintaining a clean and fresh bathroom with lesser likelihood of mildew.

Given their material, you could think that our Large Bath Stone™ Mats feel cold underfoot. But its natural stone feel actually adjusts to the temperature of your bathroom and provides a comfortable, neutral surface for your feet to land on.

Unlike cold tiles, the compressed diatomaceous earth and recycled paper composition of our large stone bath mat work to ensure it remains at a pleasant temperature. You won’t ever have to worry about getting cold feet when you step out of the shower ever again. Our large bathroom mat has the ability to blend seamlessly with your bathroom’s ambient conditions.

Absolutely. Our Large Bath Stone™ Mat is not just a stylish addition to your bathroom but also designed with sustainability in mind. Crafted from all-natural, non-toxic diatomaceous earth and recycled paper, these large bath mats are a testament to eco-friendly innovation. 

Unlike traditional mats that often contain synthetic materials and contribute to landfill waste, we’ve created a large stone bath mat that doesn’t do harm to the environment. It’s made from durable materials to ensure a long lifespan and reduce the need for constant replacements.

In the event that your bathroom and kitchen Sink Caddy tray 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 white vinegar or hydrogen peroxide will do the trick. You can view our full Care and Cleaning guide here.

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.

Watch our assembly tutorial.

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 kitchen and bathroom Sink Caddy on these surfaces. For more information click here.

Karl’s favorite place in the house

This is our second large bath stone. We bought the first one for almost exactly 3 years and decided it was time for a new one, because our cat, Karl, is absolutely obsessed with it. Like all cat parents, we mainly buy things to make them happy, and it’s just an added bonus that the bath stone is one of the best purchases we’ve ever made for ourselves too. I have several products from Dorai and cannot speak highly enough about them. So here’s a little video of Karl having his daily bath stone time and showing off.

Definitely worth it!

Works exactly as I hoped. Love them, maybe bigger for my space than I needed but I don’t care. Definitely recommending to friends and looking at other products for my place

Terrific Performance

The performance of this dries very quickly and leaves no evidence of footprints after use. The sandstone color is absolutely beautiful and enhances the master bath. My only minor complaint would be the rubber-coated platform on which this sits could allow some excess flexing based on stepping on the stones. That’s just a picky note from me but perhaps a more stable base would suffice for a process improvement note. Overall, I love these products. Not done purchasing from Dorai.

Large Bath Mat

I purchased this for a present for my wife’s to use instead of regular mats that stay wet all the time.
We have a walk in shop with no curb and no door so we tend to get more water than normal.
At first my wife didn’t think it was a good idea so I told her I would return it but she did put it down the next day and when I came home said informed me that she really liked it.
So definitely a win.
I ordered naoto make it bigger and was 1 short so I asked if they could do an order with 1 slate and 3 sandstone for the other shower and they said that wouldn’t be a problem so definitely outstanding customer service.
Would definitely recommend and so would my wife now.

Bath stone may and kitchen dishrack

The mats have been working well. I like the the Damascus earth mats kill bad stuff when it comes into contact with them. I didn’t like washing my cotton mats so that is a nice change. The kitchen rack is not a complete system yet however. The glass cup holder is way too short, the cups hang almost at a 45 degree angle and it doesn’t inspire confidence. My wood floor was wet this morning I noticed one of the cups I was able to put on the dish rack straight up leaked out onto the floor so some design changes are needed. The rest of the product is very nice! I like that the stones are beneath these dishes absorbing it so mold can’t form.

Nearly perfect

Pros
- The configurable base is a great feature and works intuitively.
- The size of each stone is great
- The stone absorbs water exactly as advertised

Cons
- One of the four stones I bought has curled at the ends, which prevents it from fitting into the base securely
- The color variation between stones is more drastic than I expected.

Thank you for your review. We are sorry to hear that one of the stones is not fitting into the base securely and the color variation is more drastic than expected. We are happy to get you a replacement. One of our customer support agents will reach out to help further.

Consistent

Just moved into my new home and love all the bath mats I have purchased. I even have the saucer mats for my dogs water bowls. The only issue with the large bath stone mat is that it comes with 4 stones and two of them are a different shade of grey and don’t exactly match the other two. They work great however and give my bathroom that extra touch of luxury.

Love These Mats

I ordered the large bath stones to replace my traditional bath mat. I couldn’t be more happy with my decision as it looks far more stylish and more sanitary. Highly recommend!

Great stones

I'm loving the stones! I had an awkwardly shaped area in front of my tub and shower so using the stone tiles I could arrange them in a way I couldn't find anywhere else. They aren't cold and absorb a lot and dry quickly.

Mixed Feelings on Stones Purchase: A Honest Review

I was initially thrilled about my Stones purchase, ordering one large, two regular-sized, and two Caddys, all in the elegant Sandstone color. Regrettably, despite the quick drying nature of the stones in this hue, I noticed that dirt becomes visible within seconds, and they tend to stain easily, catching me off guard. In hindsight, I would suggest opting for a darker color to mitigate these issues. While I still appreciate the product, I must admit it falls slightly short of the enthusiastic love I initially anticipated.

Large bath stone mat

Love that it’s modular, love the colour, the thickness, the size. It’s perfect. I have the smaller bath mat and find it a bit too small. This one is perfect for coming out of the shower. I like the low profile of it. It looks very clean and simple and minimal. This is my third bath mat purchased in my fourth Dorai product in total.

Perfect update for the bathroom!

Their stone is a huge improvement to our bathroom! I’ve always disliked rugs and how often we had to replace them.

Loving these so far!

I was looking for a super absorbent bath mat that wouldn’t get moldy because my other half does not dry himself at all when getting out of the shower and tracks water everywhere 😅

We recently moved and have an awkward space between the front of our shower and bathroom door. I loved that this bath mat allowed for multiple configurations. I was able to use two of them long-ways in front of the shower, and use the other two as a mat in front of each of our sinks. It works perfectly in our space.

My boyfriends feet are bigger than mine so we wished the single dorai mat was bigger, but I think the size works for our space. For my feet, the single mat is perfect.

I was shocked by how absorbent this mat is. It actually dries the bottom of my feet for me when I step on it. Amazing.

I plan to purchase the mats for our drying rack and sponge as well!

Thanks!

Not my favorite Dorai product

I want to start by saying that I have several Dorai products at home and have been in LOVE them which is why I ordered the large bath stone. Previous to owning this product, I would have given 10 stars all around and have influenced many of my friends to purchase these products.

We have an open shower and I was sick of always dealing with a wet bath mat so I figured the Dorai bath stone would be perfect. First off, it looks beautiful and matches the aesthetic of our room and I was extremely happy with it the first week or so. Unfortunately, after about a week I noticed some discoloration on the stones. I figured it just needed to dry but has not seemed to completely go away. I was really surprised because I have not had this issue with any of my other products.

Love it

We absolutely love it. The way it works, the design, all of it. We did 3 stones in front of the tub and one in the toilet room. Also, the small stone mat in n front of the shower.

NOT for use on carpet or rug and not easy to put together

While these do what they say and absorb water, they are very small and don’t easily come together. Please do not buy if you plan to put these over carpet or rug. They don’t mention that they will not work on these surfaces in their claim that this is made from “long lasting materials” the photos are from another item, but they broke the first day. We are below average weight.

Best decision I made, worth every dollar

I am so happy that I made the decision to buy these mats. I have a large section next to my sink that I am actually using the bath mats as a dish drying mats. The look is much cleaner than what I had before. The quality is great and everything dries super fast. Your customer service was superb. I have already told many family and friends and shared my friend’s dog’s Truffles’ IG ambassador link. Outstandingly satisfied!
