The characteristics of the single-lever faucet are simple and easy to use, and the controllability is relatively strong, which is very popular with the majority of consumers; The double-handled faucet can bring users a more delicate water temperature feeling, and many friends who are more sensitive to temperature especially like this style of faucet; The faucet with a 90-degree switch can change the hot and cold water mode by itself, which is also a style that many consumers like now.
Shower faucet: It is installed above the shower room and is used to open hot and cold mixed water. The valve body is also mostly made of brass, and the appearance is chrome plated, gold plated, etc. The ways to open and close the water flow include screw lifting type, ceramic valve core type, etc. Shower faucets are available in hose showers and flush showers: thermostatic faucets with special functions, faucets with filter devices and faucets with pull-out hoses, etc., all of which have different requirements for installation.
