We really love the result (see photo) -- simple, clean & elegant. Basically VERY easy to install. Recommendations though for DIY types: (1) Figure out a marking scheme to make sure the base is centered in both directions where you want it. The installation instructions stipulate a 4-inch hole opening in your countertop, yet the drop-through drain is on the order of less than 2 inches. So getting it centered poses a very minor problem. (2) Same goes if you care about centering the Kraus name with the faucet that you will be using. (3) Just as a caution, the 4-inch hole only will leave you with only about 3/4-inch of countertop to apply the bead of recommended silicone adhesive. This forces you to apply right on the top cut edge of the circle so as not to risk adhesive squeezing to the outer edge of the Kraus base (and therefore visible). I would have preferred more like an inch (or in other words, a 3.5-inch hole) to allow a larger bead. I was afraid (hindsight) that I hadn't used enough BUT the installation IS solid. I don't know if a 3.5-inch hole would make it anymore difficult to get a wrench on the underside sink drain nut versus a 4-inch. ... These are just installation notes as a precaution before you proceed, BUT are not meant to be negative at all -- just helpful. We totally love the powder room transformation!!
