Using this bathroom sink faucet is easy. Just turn the single handle to adjust the water temperature and flow. If you want warmer water, turn the handle towards the hot water side; for cooler water, turn it towards the cold water side. When installing, make sure to choose the right location for the handle - left, right, or center - based on your preference. Keep in mind that this is a single - hole installation, so ensure your sink has the appropriate single hole. For maintenance, regularly wipe the faucet with a soft cloth to keep it clean. Avoid using abrasive cleaners as they may damage the finish, especially the Matte Black and Chrome ones. With proper care, this faucet will serve you well for a long time.
