Undermount vs Overmount Kitchen Sink Undermount vs Overmount Kitchen Sink

If you're rebuilding your countertop, you may wonder what type of sink you should use: overmount kitchen sink or undermount kitchen sink. Each sink is installed in very different ways, and therefore have their own pros and cons. Here is a quick run-down of each type of sink as well as its advantages and disadvantages.

Overmount Kitchen Sink

This is the traditional type of sink where the edges of the sink are placed on the counter top. The weight of the overmount kitchen sink is supported by the counter top.

Pros of an Overmount Kitchen Sink

  • An overmount kitchen sink is not limited in size by the walls of your cabinet.
  • If your countertop is made from a soft material such as marble, an overmount kitchen sink aids in protection of the edges.
  • An overmount kitchen sink is cheaper and easier to install than an undermount kitchen sink.

Cons of an Overmount Kitchen Sink

  • Many people believe they are unsightly when used on a countertop made of high-end material, such as granite, because they cover the edges of that material.
  • With an overmount kitchen sink, pieces of food can easier get swept underneath the edges of the sink and stuck there. This can lead to the growth of mildew and bacteria that can be unhealthy for you and your family.

Undermount Kitchen Sink

This is a relatively new kind of sink that has become popular with the increased use of counters made of natural stone. With this type of sink, instead of being placed on top of the counter with the counter supporting its weight, the sink is installed below the counter and held in place with a strong adhesive.

Pros of an Undermount Kitchen Sink

  • An undermount sink allows the natural beauty of your counter to be uninterrupted by the edges of your sink.
  • Clean up of your counter is made easier by having an undermount kitchen sink because all food and other spills can be swept right into the sink with no obstruction in the way, such as the edge of the sink.

Cons of an Undermount Kitchen Sink

  • Certain care must be used when you have an undermount kitchen sink. Since the sink has no edges, you must be careful never to fill your sink. Otherwise water will spill out onto your counter top. In addition the adhesives that hold the weight of the sink are often not waterproof and contact with water can cause these adhesives to loosen, and your sink will fall.
  • Because of the way these sinks are held in place, it is important that they are installed correctly to avoid problems down the road. This can lead to a lot of work on your part in installation or the cost of hiring a professional to install it for you.
  • Not counting the cost of labor, undermount kitchen sinks are also more expensive than their overmount kitchen sink counterparts.
As you can see, each have their advantages. Now it's up to you to determine whether and over mount or undercount kitchen sink is right for you.
