Using this shower mixer is a breeze. First, turn on the water supply. Then, you can easily adjust the water temperature by rotating the handle. To switch between shower and bath modes, just use the diverter. When using it, make sure the water pressure is stable to avoid sudden changes in water temperature. For maintenance, clean the mixer regularly with a soft cloth. Don't use abrasive cleaners as they might scratch the brushed nickel finish. Also, check for any leaks periodically to keep it in good condition.
