We are replacing kitchen sink with new drop-in, plain white but can't
decide which type of material to purchase. We want a sink that is
easy to clean and will resist scratches and marks.

We find several types of materials, all of which brag about their
great finish but would like opinions from actual users.

We have a RO unit so must have at least 5 holes cut in the sink for
connecting faucets etc. Can all materials be drilled for these
connections?

We have been told that enamel on cast iron is tough but will show a
mark whenever a pan is placed in the sink??

Other materials show less marks but are subject to scratches??

All opinions and help appreciated.

13 years ago I went through the same data gathering. I ended up
getting a white porcelain on cast iron sink from Kohler. It has held
up fine but we do have to scour it once in a while. Note: the first one
that arrived had a corner smashed, so inspect carefully.

I was cautioned about getting stainless steel because it attracts dirt
and grease and needs to be cleaned often. My GF insisted that I not get
stainless appliances because of the cost and cleaning.

Also, I am happy with the uneven double sinks. However, apparently
wooden cutting boards are no longer available. Some health nazi decided
bacteria might grow on them. (I'm still using a 100+ year old hardwood
board my grandmother had. Nobody has gotten sick from it as far as we
know.)

I don't know what a "RO unit" is, but I would never think about drilling
holes myself.

A related feature that I'm happy with is the Chicago faucet. I really
like the high rise spout, similar to what you see in a chem lab. It
lets large pots be moved under the water for washing. Chicago is an old
company that makes quality products (at a price!).

The finish has remain perfect with no chipping, blistering or cracks.
The valves do not leak, although I have replaced the rubber seals twice.

Good luck.
