Using your Oskar Shower Mixer with Diverter is easy. First, turn the handles to adjust the water temperature and flow. You can use the diverter to switch between different shower functions. When you're done, simply turn off the handles. To keep it in good condition, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they may damage the brushed nickel finish. Also, check for any leaks periodically and if you find any, contact a professional plumber to fix them.
