Is Onyx a Good Choice for Kitchens?  Bathrooms?

Onyx is Best in Low Traffic Areas

Onyx can be used as countertops in either kitchens or bathrooms.  However, it should be limited to lower traffic areas. In other words, onyx is a soft stone that can become scratched or etched if used in busy kitchens or bathrooms. For example, if you cut vegetables on an onyx surface, you can easily scratch or chip the surface. As such, onyx countertops are best suited to areas of your kitchen or bath that don’t get heavy use.

Additional uses of onyx include:

  • Feature Walls
  • Fireplace Surrounds
  • Backsplashes
  • Tabletops & Bar Tops
  • Lobbies
  • And More

Benefits of Onyx


Similar to other natural stones, onyx is long-lasting. However, maintenance is needed because of its soft nature.

Beautiful and Versatile Stone

Our onyx is available in a wide range of colors, designs, and tones. That is to say, colors range from greys and greens to sands and blues. Most importantly, the range of colors, shades and patterns of onyx will make a beautiful and unique addition to your home or business.

Translucent Stone

As stated above, onyx is a translucent stone. Which means that if you shine a light behind it, the beam will come through completely. In short, onyx can be backlit. This creates a luxurious, unique feature that you won’t get with any other stone surface.

Natural Stone

Onyx is a natural stone. However, it is unlike other natural stones due to its other benefits. As a result, if you decide to use onyx for your home or business, you won’t be disappointed. Owning onyx is like owning a gemstone.
