Beautiful and durable
The picture for this sink doesn't do it justice. When the box arrived, I wasn't sure what to expect inside but it was a pleasant surprise. The sink has a rich high quality porcelain coating, flipped to the bottom side, it's cast iron! This sink is solid and durable. The shape is unique and although it's cast iron, it's not too heavy. This sink is easy to clean since the porcelain is coated heavily and smooth. Simple a beautiful addition.

Love it
I can hardly wait for the plumber to install. This sink is a good old fashioned cast iron model weighing a little over 30#. I love the square design. The overflow cap comes in a polished chrome but is easily removed and Kohler and others sell more colors: bronze, brushed or polished nickel. They are relatively inexpensive so you can get one to match your faucet fixture color. I like that the sink can be positioned either as an over-mount or under-mount. I will be using the latter. Also the basin is deep enough, unlike some sinks which are so shallow they hardly hold water.

Yesterday's Quality with Kohler Style
This Iron Plains dual-mounted bathroom sink reminds me of the bathroom in the home where I grew up. The sink and bathtub were solid cast iron just like this sink. The only difference is that this sink has the modern style and flair only Kohler can bring. The glossy enamel is smooth as silk. It looks very high-end. The polished chrome overflow drain cover with Kohler written on it is a very nice touch. You have the option of either drop in or under-mount with this sink. I haven't decided which one I prefer yet. This is a beautiful sink that will undoubtedly last a lifetime.

Great design and great quality

Very Heavy
Trust me this is a Heavy sink if you plan to use it as an undermount. The finish is very nice in black. The overflow cap is a cheap looking plastic pop in that looks like it will fail eventually and only comes in chrome (would be nice if Kohler offered color options for the cap like brass, black or white for white sinks). We will be using 2 of these sinks in a master bathroom vanity and will be fabricating a special mounting bracket to hold the weight of this iron in place. The mounting surface for undermount is not really correct but will work per other users.

The sink is listed as an under mount/drop inThe design of the top surface for under mounting is not flat enough and has to rounded of a lip. Clamps will not hold.Drop in I would give it a five star.
