And how about durability as a flooring option? I mean .. What is the expectancy of its shine, gel layer and life in general? In a nutshell is it a viable option for living room floor? And if yes, then would its edges match or would it still be like tiles where edges don't quite match?

I am finding many color tones in the Dyna marble maybe choose that first then see if there are tones of gray in that choice as for cabinet color I think the floors should be the same throughtout and if you want gray you could do the cabinets gray if that tone is in the floor

if you kitchen is seperate and isn't attached to the living area then you have the liberty to choose tiles according to you kitchen decor or your liking or if not then you may choose something similar to the texture of marble and tiles are nice and does not requires any polishing on it.have a nice day
