Is the right side of the sink larger or the left? The picture makes it look like the right is bigger which is what I want but the dimension guide says the left is larger
A. The Kohler K-3839-4 has a 13" basin on the right side. The right basin is smaller.
is there a dish drainer that sits on the top of one of the sinks for this model?
A. The Kohler K-3839-4 comes with the Basin Rack for the Large Sink Basin, there is an optional Basin Rack for the Small Sink Basin which is Kohler K-6647. Kohler does not offer any racks that sit on top or over the sink itself, only within the basins of the sink.
Can I get this sink with the small side on the right instead of the left?
A. The Kohler K-3839-4 is only available in the configuration shown here.
Does it have sound dampening? The tech specs says it does but another comment on a similar Kohler vault sink says it does not
A. All Stainless Steel sinks made by Kohler have sound dampening. It is a pad that is put on the outside of the basin.
For u;ndermount installation can the sink be drilled for a 5th. hole to the left?
A. A skilled plumber or contractor should be able to drill a fifth hole, however it would void any manufacturer's warranty on the product.
Is the K3996-4 available with the large basin on left and small basin on the right?
Unfortunately the K3996-4 doesn't come in that configuration.
