What are the Benefits of Undermount Sinks?

The biggest benefit of an undermount kitchen sink is it does not have a crevice or lip that cod could accumulate dirt. With these sinks, you can brush crumbs or directly wipe spills into the sink without any stuff getting stuck onto the rim. For the ease of cleaning alone, it’s a good option for a lot of people.

Waterproofing is essential since the countertop edge will be exposed to liquids. Laminate surfaces are not ideal for the undermount kitchen sink, but granite and other solid surfaces are good.

Best Undermount Kitchen Sink Buying Guide

There are a lot of different undermount sinks, so how do you choose the right one? Here are some of the factors that you may want to consider.

How Many Basins?

One Large Basin

One large sink allows you to wash a large pot, skillet or several plates or food at the same time. However, it’s tricky to rinse veggies while cleaning a large pot simultaneously. The good news is single basins have become deeper and larger.

An ideal single basin sink is 7 to 10 inches deep with a width of 33 to 36 inches. With these specs, you’ll have enough space for cleaning and food prepping.

60/40 Double Bowl

An offset, two bowl sink is ideal for preparing food and cleaning dishes at the same time. A typical 60/40 double has a 14 inch and 18 inch wide bowl. Usually, the small bowl is for preparing food and the larger one for cleaning.

A double basin sink is ideal for cleaning items that cannot be washed in a dishwasher. You could for instance, rinse water in one and soap in another basin.

The drawback with a double basin is it’s difficult to wash large pots and pans. But if you are after flexibility or used to a two basin sink there is no reason to change.

A 50/50 Sink

This is exactly what the name says, the basins are divided 50/50. The symmetrical design appeals to a lot of people, and the even design makes it easy to wash, clean and prepare food. The only con with this sink is that it’s hard to clean large cookware here.

3 Basin Sinks

A three basin sink usually has two large basis and a third small one used for disposing of garbage. These basins offer a lot of flexibility and options for cleaning, washing and food prepping. This is also handy for those who want the garbage disposal nearby.

The disadvantage with this sink is the basins are small and unsuitable for cleaning a lot of large dishes. If you do opt for this make sure that it’s suitable for your cleaning requirements.
