Plumbing a shower base is the process of connecting the shower base to the drain and water supply lines. It is an important part of installing a shower, and it must be done correctly to prevent leaks and other problems.
There are a few different ways to plumb a shower base, but the most common method is to use a shower pan. A shower pan is a pre-made ing liner that fits over the shower base and connects to the drain. The shower pan helps to prevent water from leaking through the shower base and damaging the floor or subfloor.
