There are many considerations when choosing a faucet for an existing kitchen sink. Aesthetics is one consideration. The faucet should be in proportion to your sink. Try not to put a small faucet on an oversized sink, and try not to put a huge faucet on a tiny sink. Check how many hole drillings you have in your sink before you have your heart set on a style.
No matter how beautiful a faucet is, make sure to buy one that is durable. The last thing you want is to have to replace your beautiful, expensive faucet in a year or two. Most faucets come with a warranty. Check to see that the warranty is long enough for the life you expect out of the faucet. Another way to check for durability is to check online reviews for that particular model to read about other people’s experiences.
Some faucets have special features such as anti-scald capabilities or thermostat valves to let users choose from temperature on a dial.
Faucets come with sink hole requirements. Some require one hole (for single handled taps); some require three holes (for models with separate hot and cold taps.) Some are designed for sinks with three holes even if they only have one variable tap. If you choose other features such as dish soap dispensers, spray nozzles, or hot water dispensers, these each require a separate hole.
Some kitchen faucets actually pull out and can be used to spray down the sink (they are connected by a hose). Older styles have a separate hose and nozzle situated beside the tap. Some have a higher arch to accommodate large pots or items. Base your choice on what you need as far as function, handles, size and looks.
Consider the other hardware in the room and choose something complimentary. The number of finishes to choose from is ever increasing. A few choices are stainless steel, chrome, brass, copper, brushed stainless steel, Venetian bronze, satin, blackened bronze and anthracite finish to name a few.
With all the possibilities, you are sure to find the perfect faucet for your kitchen.
