Actually, unless something has changed, the faucet is mounted on the counter. There are no holes in the sink itself whether it is the stainless or the plastic. If you wanted a faucet with 4" centers I would check with Reace just to make sure that there is not some mounting issue, but the sink really doesn't come into play.
