Kohler K-6489 is an impressive and very popular minimalistic single bowl sink. it has an elegant look that will decorate any kitchen.  It’s bottom is designed at a 2 degrees slope towards the drain that makes the cleaning very easy and usage simple. It is also silent. Cast iron absorbs the sound of falling water much better than other materials.

But there are a number of Kohler Whitehaven single bowl kitchen sinks that may look quite the same at the first glance. Those are K-6487, K-6488 and K-6489 model numbers, so to keep track of what is what.

An interesting fact to know is that the price difference between these models is minimal. White finish, as a rule, comes with the lowest price. But if you choose some other color of the finish, you will have to count with much higher price. There are around 20 different colors available for each of these models.

Here we have 2 models of cast iron farmhouse double sinks. Kohler K-6426 is the short apron version while Kohler K-6427 comes with tall apron. Both sinks have Smart Divide® solution for the divider between the compartments. That means that the divider is lower than the sink is deep.

  • Lowered divider between the bowls. This feature is called Smart Divide® technology. Owing this technology, you can use the sink as a single sink for large cookie sheets and similar items. Meanwhile you still have the streamlined convenience of a double sink.
  • Button sloping 2 degrees towards the drain. This

Difference Between Tall And Short Aprons

The difference between tall and short apron height is 2 2/16 inches. Short apron height is 6 11/16.  Tall apron height is 8 13/16.

I like the tall apron. The sink looks confidence inspiring. On the other hand, the shorter apron will help if you want freer access to the under sink storage.

Look And Feel

Cast iron farmhouse sinks is the type of sink we would recommend to the homeowners who love robust long lasting things in their homes. But the enameled cast iron gives the sink also a look of an elegant high end object. This way, the cast iron kitchen sinks will suit also the most refined taste.

For Whom We Don’t Recommend Cast Iron Farmhouse Sinks

1. Not suitable and not even needed for tight budget. Cast iron nowadays comes with the air of luxury. Its price is quite high. So this type of sink may not suite a tight family budget. But there is no strain either. There are a lot of high quality stainless steel sinks and granite sinks. They may not be quite as robust or easy to care for but most of them will serve you very well for many years. A good quality stainless steel sink is a good investment too. But if you are in farmhouse or apron sinks so very much, then you can find some very decent models made of stainless steel sheets.

2. If the cabinetry is too delicate. These heavy cast iron sinks require a sturdy cabinetry. A sink of 104 pounds won’t stand confidently on something fragile. You may need to purchase a new cabinet to accommodate the sink if you really can’t get rid of the idea of a cast iron sink. But if your existing cabinets are of high value, then a lighter weight sink should be chosen.
