Who you will be working with

When you call Superior Granite or walk into the showroom, you are dealing with a family business, not a call center. Carlos and his crew are the people who measure your space, cut your stone and do the work in your home.

We started with granite and quartz countertops, and we still fabricate every top in our own shop. Today the same crew also handles tile, custom shower pans, luxury vinyl plank and laminate flooring, and carpet.

What we care about

  • Doing the fabrication ourselves. Measuring, cutting and installing stay with one company, so nothing gets lost between shops.
  • Seams you don’t notice. We plan seams around your layout and the slab pattern.
  • The parts you never see. Like a shower pan floated by hand and waterproofed before any tile goes on.

Our showroom

Our showroom is at 731 N Columbia Center Blvd #116 in Kennewick, inside the Colortile of Kennewick showroom. Colortile is a separate, locally owned sister business. Sharing the space means you can see slab, tile, flooring and carpet samples in one visit. Plan your visit.
