Both of the Mohawk Simplesse tile products that we have are 12 inches by 24, and 4mm thick. With it’s 12 mil wearlayer you are looking at a good quality floor that can be used in either a residential or commercial application. Just because we are selling it cheap doesn’t mean this is a cheap floor. When you compare it to those thin 6 or 8 mil products priced at $1.39-1.99, you will see the value in this product. The Espresso Russet is the lighter of our 2 colors, and will contain a larger amount of contrast. It should look good dirty!.
