This sink is usually installed as a drop in. That is what you commonly see. However because I wanted the surface of this vanity to be easy to access and keep clean, I instructed the tile setter to imbed it into the thin set and tile iPad to its edge. See photo below. I didn't want to lose the blue edge of the design either which I would have if I had undercounted it. Also I needed as much uncounted knee room as possible for my client to use the space in her wheel chair. Thanks for asking!
