Not sure this is the norm. But on installation day it took two guys less than 3 hours to take out the old countertops and put in the new ones. We were surprised how quick everything went.
The tile backsplash wouldāve been done the next day, but we had to wait for the new ālow profileā microwave to come in.
The company we had did the plumbing the next day which was nice also. We did have a couple of blemishes on one of the quartz countertops. But they replaced that one no problem.
