Using your Mica Shower Mixer is a breeze. First, turn the mixer to adjust the water temperature and flow to your liking. To switch between shower and bath modes, simply use the diverter. When using it, make sure the water pressure isn't too high to avoid any splashing. For maintenance, clean the mixer regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can damage the chrome finish and the mica material. Also, check for any leaks periodically. If you notice any issues, it's best to contact a professional plumber for help.
