I have this on a 5' granite slab. It is a little small and shallow, but as noted, it does not splash. Be sure you install your faucet so that it is nearly directly over plug center. My plumber put it too close to back of bowl, and I have to be sure to protect the water from splashing out the back when I have my hands under it. Running directly, it is fine. I wish they had brushed nickel - the chrome too easily water spots.
