What undermount sink materials can be paired with laminate countertops? What sink models are available?
To be undermounted to high pressure laminate, a sink must have an approximately 1” wide rim that is made from a resin, has been machined completely flat and meets the bowl wall at a sharp 90-degree angle. Our Karran acrylic sinks meet these specs, but so do a few other acrylic solid surface sinks on the market.
Most stainless steel sinks don’t meet this rim spec because they have steel rolled rims – except for Karran’s Edge sinks. Our patented sinks are made of stainless steel, but feature a modified resin rim that fits the specs outlined above and allows them to be seamlessly undermounted in high pressure laminate.
As for model designs, the sky is the limit, apart from one caveat: double bowl sinks must have a lowered bowl divider. This allows for router bit movement between bowls during installation.
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.
