Unfortunately Wayfair seems to have confused the 16 gauge stainless steel with the width dimension.  The Pax sink does not actually come in a 16” width.  It arrived with the Wayfair label saying 22.5 x 16, but the manufacturer’s label saying 22.5 x 18.5.  I needed a sink 17” wide or less so this was unsatisfactory.  Wayfair was quick to acknowledge this and will arrange to take it back and refund my money.
