What do finish do you recommend? I have stainless steel appliances on order.
"Satin finished sinks are not susceptible to water corrosion but brushed stainless steel is"
While @elgaagm might also call me a "Karen" for wanting to debunk what she wrote, I am going to go ahead, for the benefit of others coming across this thread who might think what she wrote has credence. I do not know what she meant by "water corrosion", but I'll assume she meant rust. Stainless steel does not rust. That is the reason that stainless steel bolts, screws, and other fasteners are specified and required for roofing, boats, marinas, and other maritime purposes.
When rust is seen in a stainless steel sink it is because something that was left in the sink is itself rusting. It could be that the homeowner used steel wool to clean the sink, which should never be done, and the steel wool left tiny particles in the sink that rusted. Or it could be from a metal object left like a spatula, can, can lid, or similar. Or it could be that the homeowner's water is hard and has a good amount of iron. When that hard water dries it leaves a rusty film from the iron content.
All of the above can be easily removed by Barkeepers Friend in a couple of minutes. As to satin or brushed finish, it would make no difference if something is left in the sink that rusts. Even if a brushed finish might have miniscule grooves (I have never heard of a complaint about this), if hard water is going to sit in the sink, it will sit there regardless. Perhaps cleaning the sink when it has miniscule grooves might take an extra couple minutes, but nevertheless @elgaagm's statement that sinks with a satin finish are thereby impervious to what she called "water corrosion" does not have merit.
As to @elgaagm's linked website, "Arthur Harris", it looks like a good company that makes stainless steel float balls, with no mention of sinks. The site does mention its floats are made of stainless steel for specialty use in high-pressure high-temperature water or in corrosive liquids due to the strength of stainless steel "where strength, minimum corrodibility and maximum buoyancy are necessary. Stainless steel floats have high strength at temperatures up to 800(degree sign) F (427 C)."
