Depth of Bathroom Sink
I am selecting a bathroom sink. It will be undermounted and I am leaning towards a rectangular shape.
I am confused by the depth of the rectangular sinks. I was looking at a Toto model and the depth is 4" which seemed quite shallow. I then started looking at other options and a Kohler version (the Kathryn) has a depth of 3" which is even more shallow.
Am I missing something in terms of what the appropriate depth of an undermount sink should be. I am more familiar with standard bowls which slope down so the middle seems deeper.
Is 4" or even 3" the norm for a rectangular bathroom sink - undermounted if that figures into the calculation of appropriate depth.
