Using this shower set is easy. First, install it on the wall following the included installation accessories. Connect the water inlet to your water supply. Then, adjust the height of the shower rail according to your needs using the up - and - down sliding function. You can choose from three spray functions: massage, rainfall, or a combination of both by simply adjusting the settings on the handheld shower head. When using, make sure the water pressure is within a reasonable range. To maintain the shower set, clean it regularly with a mild soap and water solution. Avoid using abrasive cleaners as they may damage the chrome finish. If there are any issues, you can contact us as it comes with a 10 - year warranty.
