You will love this shower drain. It is different from the general shower drain. It has a lot of upgrade functions, and it is connected to the waste pipe and fits standard U.S. plumbing connections. Barrier-free shower floor drain square grid cover enhances water flow rate and separates the dry area and wet area. The hair Strainer collects hair and other debris, preventing pipe clogs. The rubber coupler prevents water leakage at the joint between the base flange and the waste pipe.
