I went to install a full size Kohler cast iron top mount self rimming kitchen sink on a granite slab. It wobbles from one corner to the opposite corner by about an eighth of an inch. I called the plumbing supply place I bought it and at first they were going to exchange it for me. Then they called Kohler. Kohler told them that they do not exchange unless the wobble is more than a quarter of an inch. My goodness. Can't Americans make anything well?!!!!!
My concern is that most of the weight will be on the preassure points of the two corners that will be in contact with the granite slab. I am afraid the granite will crack. I know the caulking will absorb and distribute some of the weight but with a sink this heavy I am sure the sink will sink through the calk and make contact with the granite at only two points. Has anybody used a grinder to grind a sink flat? How about if I put a small rubber washer under the contact corners or some other shim so there wont be metal to granite contact?
I went with Kohler because I was told it was the best. I like the top mounted sinks because they are easy to keep clean and you don't have to worry about them falling off the bottom of the slab.
