I'm confused about this particular Kohler sink:
which is described as being for "tile-in or metal frame installation". The
installation guide describes the tile-in option as mounting the sink flush
with the surrounding tile -- which I've heard of. But the other sinks I've
seen designed for this kind of installation had square corners. This one
has rounded corners - could a tile installer really cut curved pieces
accurately enough to mate with these corners?
The reason I ask is that we have this sink sitting in our living room :) We
bought it because it's an exact match for the old sink we're removing, but
I'm wondering if we should exchange it. The countertop we pulled out was a
mortar job with the sink edge concealed under the tile. But it seems
nowadays all the tile installers use backerboard and I'm at kind of a loss
how this sink is meant to be installed.
