What to look for in an undermount sink
Confirm your countertopneeds solid stone or quartz; laminate and tile usually need drop-in
Decide on the revealask your fabricator about flush, positive or negative reveal
Count the extrasclips, drains, flanges and grids are not always included
Frequently asked questions
Can you put an undermount sink in a laminate countertop?
Usually not. Kraus says its undermount sinks are best suited to solid surfaces like granite, marble, soapstone and concrete, and not to laminate or tile. If you are keeping a laminate counter, look at a drop-in sink instead.
What else do I need to buy with an undermount sink?
Check the box contents. The Kraus Premier includes a drain and mounting hardware but no grid, the BLANCO Diamond needs its clips and strainer bought separately, and the Kohler Prolific needs a separate drain or disposal flange.
What is the best 33 inch undermount kitchen sink?
The KOHLER Prolific 33-inch is the premium pick: an 18-gauge stainless steel single-bowl workstation sink with three graduated ledges inside the bowl. It comes with a bamboo cutting board, two grated racks, a colander and a wash bin. The drain or disposal flange must be bought separately, and it needs a 36-inch base cabinet.
What are the best stainless steel undermount kitchen sinks?
The Ruvati 32-inch workstation sink is the best overall pick, with 16-gauge T-304 steel and a colander, cutting board and drying rack included. The Kraus Premier is the budget pick in 18-gauge steel, the Elkay Crosstown is the double-bowl option and the KOHLER Prolific is the premium workstation. All of these are undermount and need a 36-inch base cabinet.
