Searched a few articles, but did not find the information I am seeking. Exactly how does this process work? I have been told "you must buy a whole slab" for both granite and quartz. If this is true, how do the remnants occur? Does the fabricator keep what is left over? Also, my cabinet maker prefers a certain fabricator who favors a certain supplier. Am I bound to use these two sources? If not how should I handle the situation? We are starting our remodel with a master bath and really wanted Cambria quartz, but the countertop will only use 20 sq ft. What would become of the rest of the slab? Found some granite, both a small slab as well as a remnant at two different suppliers, but is this rude to my cabinet person? As you see, I need a countertop 101 course as to the buying process in detail. Thanks in advance for any explanations.
