A shower dam, also referred to as the shower curb, is the raised section at the entrance to the shower that keeps the water in. In this article, we will discuss some regulations and methods for replacing an old shower dam or building a new one.
The first thing you have to be aware of when working on a shower dam is your local building codes. Some local codes say that curbs must be from 2 to 7 inches high. Be careful though, because I have seen other codes that state dams or curbs must be 3 to 9 inches high.
