Shower drain assemblies

Abstract

Shower drain assemblies and their components are disclosed. In some examples, a shower drain assembly may include a shower drain, a retaining ring, a sealing ring assembly, or a combination thereof. The retaining ring may fit inside the shower drain, and the sealing ring assembly may fit inside the shower drain and on top of the retaining ring. In some other examples, a shower drain assembly may include a shower drain, a gasket, a compression ring assembly, or a combination thereof. The gasket may fit inside the shower drain, and the compression ring assembly may fit inside the shower drain and on top of the gasket. The shower drain assemblies may allow for fluid pressure testing of shower drain and pipe assemblies. The shower drain assembly may allow for fluid pressure testing of areas not previously tested or a lack of a need for caulking, among other improvements.
