I have p-trap entry in drain at 16" above the floor. However, vanity that I got has lower drawer which has top at about the same height. There is also about 4" clearance behind drawer. I was told that the only way to install p-trap would be to cut back of the drawer.
So I wonder if it's really the case. Can't drain entry be just raised with some additional elbow so p-trap enters it 6" higher? Any other options? Is it possible, for example, to install p-trap sideways so it fits into those 4" behind drawer?
