The sink generally is of nice quality, HOWEVER, they have poor quality control on the drain opening.  Manufacturer states that it has a 3-1/2” diameter opening.  At the top of the opening it is 3-1/2” but at the bottom of the opening it is 3-5/16” not allowing for a simple installation of a garbage disposal!  In contacting the manufacturer to see if it might be ground out slightly they wanted to take no responsibilty.  When Wayfair contacted them they said the sink  had not been tested for the vibration of a disposal......What?????  What a cop-out!!  I share this as warning.
