Types of Faucets

Start by identifying the type of faucet you already have. There are three main faucet types available today: single hole, 4” triple hole, and 8” triple hole. In the single-hole faucet, the center control typically not only serves as the spout but the mixing valve as well. In the triple-holes faucets, the center device is usually just the spout with the mixing valves 4” or 8” from the center on each side respectively. Depending on your existing situation, the faucet may be installed to the countertop or the sink, so if you are replacing one or the other, you have the option to change faucet type. If not, purchase a new faucet to match the type you already have. The one exception would be that single-hole faucets can typically be used in a 4” triple-hole sink or countertop if they come with a blank base plate to cover the additional holes. One added benefit of separate mixing valves is that most manufacturers use one valve with many different trims. This will let you change the style in future with less waste and work. In our case, there was a 4” three-hole faucet installed to an integral sink cultured-marble top. Because we were also replacing the countertop and sink, we decided to go to a widespread 8” triple-hole faucet to match the new larger sink.
