Features to Consider When Choosing the Best Undermount Kitchen Sink
The materials your sink is made of can make all the difference in every day use. Timeless and durable materials like stainless steel will last for a long time without rusting or scratching but may not fit your style.
Plastic or acyrlic sinks are less expensive, but they may stain over time. Fireclay and copper sinks are beautiful and classic, but they may need special care and cleaning. Each material has its pros and cons when it comes to expense, durability and care instructions.
Depth of Sink Bowl
The depth of ideal undermount sink bowl depends on your needs. If you want to wash large or bulky items in your sink, a deep sink basin is ideal. Practical issues like a person's height or water consumption also come into play when thinking about how deep a sink should be. Convenience is the key here.
For example, larger sink bowls will require more water to fill up. You will want something that you will be able to easily reach, clean and use according to your needs.
Partition vs No Partition
Some sinks offer one or more partitions. These separate compartments can be perfect for washing and drying dishes, or for those who wish to use a sink for more than one purpose at a time.
For example, you may wish to hand-wash clothing on one side of the sink while soaking dishes in the other. Single basin farmhouse kitchen sinks, however, can have multiple uses too. Read my detailed guide to choose the best farmhouse sink.
The best undermount kitchen sinks come with careful installation instructions. Occasionally you may encounter some issues. A porcelain sink may need a larger drain hole, for example, so time and materials allowances should be made for installation. The right brackets and sealant should also be used.
While most sinks come with standard drain capability, some are smaller and others are larger. Be aware of the different draining methods and choose one that works best with your plumbing. If you wish to have a garbage disposal, be sure to choose a sink that can accommodate it.
Tips for Installing an Undermount Sink
