Using this Pavia Twin Shower Set is easy. First, connect the shower set to your water supply according to the installation guide. You can choose between the overhead shower head for a wide - coverage shower or the handheld spray for more targeted cleaning. When using, adjust the water temperature and pressure to your comfort. As for maintenance, regularly wipe the shower heads with a soft cloth to keep them clean. Avoid using abrasive cleaners as they can damage the brushed nickel finish. If there's any blockage in the shower heads, soak them in vinegar for a while and then rinse thoroughly.
