Choose Sinks: Drop-In or Undermount?

An undermount sink is installed beneath the stone countertop, usually by glueing the lips of the sink basin to the bottom of the countertop and otherwise strapping or supporting it. A drop-in sink, conversely, is set down into the countertop with its rim over the edge of the granite. With both, you need to be careful to prevent moisture or grime build-up inside the seam. Each style has its own unique advantages, which you should consider when choosing a style.

Undermount Pros:

  • Maintains the continuous flow of the granite for a kind of “infinity pool” effect

  • Modern, clean feel

  • Weight of sink easily supported by strong materials like granite or marble

  • Maximum ease of cleaning counters and keeping surface germ-free

  • Usually provides for a deeper basin

  • Better resale value for your home

Drop-In Pros:

  • Granite rim is not exposed to chipping

  • Can accommodate vintage, specialty, or heirloom sinks

  • Generally less expensive than undercount sinks

  • Faucets do not need to be cut into the countertop or wall

  • Does not require professional installation

Bear in mind that when you get new stone countertops, part of the installation is cutting you a hole for your sink basin. Though it can be difficult to retro-fit a countertop with an undermount sink because it needs to be exactly the right size, it’s much easier to do when you install both parts simultaneously.
