Problematic Bottom

Due to the extremely flat bottom of these sinks, some customers have reported that the sink may leave a bit of water standing in the bottom after use. This creates the need to wipe the sink after using it.

Due to the fact that all water does not fully drain out, if you do not wipe the sink or at least clean weekly, you may have a mold issue. It is not reported as an issue that should prevent someone from purchasing the sink, but it is important to be aware of it.

Things to Be Aware of Before Purchasing

  • Install this product according to the installation instructions.
  • Countertop manufacturer or cutter must use the current product template available on the manufacturer website
  • Kohler Co. is not responsible for cutout errors when the incorrect cutout template is used. This means you must be very careful if you are placing granite or another top over this sink.

The Verticyl line of sinks from Kohler is similar to its other products, durable, high-quality, and suitable for many different styles of home. With various shapes and colors to choose from, you can match every bathroom in your home.

Whether you have children, or you are a bit forgetful, with a built-in overflow drain you will never need to worry about flooding.

This sink is essentially perfect for any home, and at a very affordable price. The only factor to look out for is the fact that there is a very flat bottom. Despite this, the Verticyl line of sinks is highly rated and very popular.

These sinks can be coordinated with other products in the Verticyl line or enjoyed on their own as a stand alone sink bowl. Install with ease, and enjoy your easy to clean, attractive, ADA compliant, and durable Kohler sink.
