Concrete countertops are just one of many kitchen countertop options. You can buy precast counters from fabricators that are cured and finished in the workshop and delivered straight to your kitchen for installation. Or you can do it yourself by making your own molds and fixing your counters at home.
Kitchens with modern designs—lots of smooth surfaces and flat-faced cabinets—work well with concrete countertops. The beauty of these countertops is that they make a subtle design statement and can work with many different kitchen styles.

Plus, concrete doesn’t mean you’re stuck with gray, as there are many different color countertop options, especially if you’re buying them from a fabricator.
