Any suggestions new kitchen floor - looking for 1 piece

In the process of remodeling 1 store and moving another. does anyone have any experience with a 1 piece floor. possibly a spray over - polymer. We have 4x4 red clay tile in our kitchen now and its a pain to keep the grout / tile clean

We have a poured rubberized covering over our concrete. It can be made in just about any color and the best feature is that it is textured to be as “no slip” as a floor can be. Biggest problem is that the no-slip texture means that a layer of grime can build up near the walls and other spots where mopping isn’t thorough.
