1. The water saving function is the key point to be considered when purchasing a shower head. Some showers use a steel ball valve core and are equipped with an adjustable hot water controller, which can adjust the inflow of hot water into the mixing tank, so that the hot water can flow out quickly and accurately. This type of shower with a more reasonable design saves 50% of water than ordinary showers. The multi-stage function of the shower is mainly to adjust the water output through different water outlet holes to achieve the effect of water saving. The new type of water shower can divide the water into thousands of small water particles like raindrops. The most prominent water-saving method of the single-strand shower is the fully concentrated water column. Although the flushing is powerful, each nozzle will automatically reduce the water volume. 2. Secondly, pay attention to whether the shower is easy to clean. 3. Shower accessories will directly affect the comfort of its use. 4. The design trend of shower products is the combination configuration of fixed shower and hand shower, that is, the fixed and hand shower are installed separately at the same time. 5. Most of the shower products are mainly made of plastic, and the more high-end ones are made of silicone. 6. In addition to the water outlet, the shower also has various functions such as energy saving, self-cleaning, and constant water temperature.
