Experience the same instant drying power as our Bath Stone™, now in double the size with a customizable blueprint. Patent-pending design has enabled us to create the largest diatomaceous earth bath mat on the market. Made with Diomat™ technology, this mat feels similar to a durable ceramic material and stays at room temperature (no cold toes please!). 

Unlike traditional bath mats that absorb moisture and generate bacteria, the Large Bath Stone™ is designed to instantly remove water, actually helping prevent mold. Customize your layout with 4 adjustable tiles to fit any space. The Large Bath Stone can be arranged in a rectangle, straight line, U-shape, and more. 

Includes 4 instant-drying tiles in the color of your choice, 4 non-slip rubber base pieces that nest the tiles, and 8 firm plastic connector pieces. This design is patent pending.

Dimensions: 31.6 (width) X 22.3 (length) X .6 (tall)

  • Made with eco-friendly, non-toxic, and long-lasting materials.
  • Dries instantly thanks to Diomat®, our sustainable combination of diatomaceous earth and recycled paper.
  • Helps prevent bacteria growth by eliminating the moist environment where mold thrives.
  • Functional design created for the modern home.
  • This product is made from compressed diatomaceous earth and recycled paper, so white spots and slight color variation occur naturally in the production process.

Cleaning Instructions: If your stone gets stained, it can be cleaned in two ways. For light stains or scuffs use the included sanding tool to gently rub off any marks. We recommend doing the sanding in a well ventilated area. For more extreme stains, use a small amount of hydrogen peroxide or bleach to treat the area.

No wet cold feet!

Dries my feet immediately leaving the shower. The stone stays warm/room temperature too! Easy maintenance. Everything is as advertised! Worth the investment!

Pleasant to use

They arrived promptly, and were well packaged. They look and feel much cleaner than a math mat.

Great product!

I was skeptical prior to purchasing especially due to the cost. However, the product is great! Does just what it says it does and looks great in our bathroom. So glad I can stop using bathroom rugs!

Love It!

Couldn’t find any real diatomaceous earth bath stone mats of this size. Dorai Home was the only brand we found available and my husband and I both love it!

The bath mat is porous so it absorbs and dissipates the water very well. We’ve used it for couple weeks now and it doesn’t stain or smell like regular mats. It also has a nice chic look.

My partner and I absolutely love these bath stones. We used to just have gross mildewy towels or bathmats (we were not great at keeping up with swapping them out and laundering them), and this is a great solution for us. The stones feel nice under foot (like a nice soft yet textured, non-slippery stone) and absorb and dissipate water so quickly! I love showing guests the "splash test" and flicking some water onto them and watching it near-instantly disappear. Just awesome.

Love the configurability (is that a word?) of the large stones, we have three of them in our main bathroom and one of the stones in the guest bath. We got the ivory color and so far they haven't started looking dirty (we've had them for maybe about a month now). Overall, just very pleased with my purchase! Looking forward to seeing how long these stones last. :)
