One piece would be sweet, you should be so lucky, I've been out of granite setting over 10 years, it is nice work, always high end. Don't bump the dam legs on something or you own it, transporting is tricky , and tilting is tricky . Get ya a tube of black silicone as well as some soapy (dawn) spray bottle water. For dressing any edges up. Always have joints 1/16" on bottom to be able to remove adjoining material in future.
Don't get cocky if you do well on this one, say countertops in a kitchen , the stuff cracks if not handled or set properly , and is expensive to replace. I know!
