Urgent! undermount stainless sink advice need!!!
My contractor is to install undermount stainless sink & granite counter
top tomorrow, but he told me that I will have to break the granite if I
decide to change the undermount sink later on, is this true or he does
not know how to install undermount sinker correctly?
Please advice.
Thanks in advance.

I have an undermounted "granite" sink on my Silestone counter. The granite
powder/epoxy sink is just siliconed (plus some metal supports) to the
counter top and if the counter top can be removed from the base cabinets in
one piece, replacing the sink would be quite easy. BUT, and it's a big
"but", granite and Silestone counter tops can be installed on base cabinets
in a way that make removal of the counter top very difficult if not
impossible without breaking the counter top. My installation had something
like plywood or MDX (?) board screwed into the top of the base cabinets,
then caulking applied generously on top followed by the setting of the
Silestone above it all. When I asked how this top could be removed, the
installers said that it would be possible at times to use many screws driven
from below the plywood or MDX and slowly tighten the screws, wait, slowly
tighten some more, wait, etc...until the force of the many screws broke the
adhesive between the plywood and Silestone allowing the counter top to be
lifted off. He also said this may fail and either not remove the counter
top--or break the counter top in the attempt.

So, to me, loss of a counter top does seem a possible outcome in a future
sink replacement, not only for trying to replace a sink, but for any attempt
to remove the counter top.

The shop that did my work has been in business for well over a decade and
is the primary installer of Corian, Silestone and granite in northern
Arizona, so I assume they know what they're doing. And from watching the
sink and counter being installed, my counter top would have to be removed
from the cabinets to be able to replace the undermounted sink. A new sink
couldn't be installed with the counter top in place.

Of course, with an above-mounted sink, the counter top could stay in place
as you replace a sink. Just hope that the opening req'd for the new sink
matches the hole you have!

PS--personally, I find SS sinks to be too much work to keep sparkling. Have
you looked at granite sinks (Moen, Pegasus, etc?)

PPS--an undermounted sink really "adds" to a kitchen, in my opinion, as well
as making counter top cleaning easier. Given the unlikely event that you
would ever need to replace the sink, go for the undermount! ;-)
