Laminate Countertops LOVE undermount sinks!
​

Why would a homeowner or designer choose an undermount sink over a top mount sink?

Undermount sinks are preferred from aesthetic, hygienic and practical points of view.

Aesthetics

​Undermounts appear sleeker and more streamlined when installed underneath instead of on top. Most top mount sinks have a fairly thick rim (more than ½”) that is obtrusive. Undermounts look like a more premium offering.

Hygiene

​Top mount sinks are sealed to the countertop with silicone, creating a bead that's tough to keep clean. With all the moisture around the sink area, this bead can promote bacteria growth and the eventual degradation of the actual silicone.

How does Karran ensure no moisture issues arise when pairing laminate countertops with undermount sinks?
​
We use a solid surface seam adhesive to bond the 1.25” wide rim directly to the back of the high pressure laminate. This methylmethacrylate, two-part, permanent set epoxy has been used for 10 years, and we have never had a seam failure. It is impossible for water to get through the seam in any way.

Practical
​
Isn’t it nice to mop all that water on your kitchen countertop directly into the sink? You can only do this with an undermount. Also, it’s easier to wipe food prep remains directly into the sink when unhindered by a thick, top-mount sink rim.

How do you care for a laminate countertop with an undermount sink?
​
There are no special care requirements for undermount sinks in laminate countertops. Clean the laminate as specified by the laminate manufacturer; the same goes for the sink. Just because it is undermounted, it doesn’t mean that either component requires more careful maintenance.
