Voss is a transitional bathroom line on the standard Duralast cartridge. Units made before August 2018 use a different mounting nut, which only matters if you are reinstalling the faucet.
Before you start. Shut off the two small valves under the sink by turning them clockwise, then open the faucet to confirm the water has stopped. Plug the drain so small parts cannot fall in. You will need a screwdriver, an adjustable wrench or pliers, and for most handles a hex key (an Allen wrench, sold as an inexpensive set at any hardware store). If a shutoff valve will not turn or starts to drip, or anything is corroded and will not loosen with moderate force, stop and see when to call a plumber. New to this? Start here explains the parts and tools in plain language.
