Abstract: A shower manifold for installation in an existing enclosure includes one or more bifurcated conduits each having a main branch and an auxiliary branch. The main branch is in fluid communication with a bib in the enclosure, either directly or through a flexible hose. The bifurcated conduits are connected with straight conduits and attached to spacer shafts as required to extend between the walls forming the enclosure. Shower heads are mounted to the auxiliary branches, which are angularly oriented to direct the water stream within the enclosure. A cruciform conduit having two transverse branches may also be part of the manifold. Two shower heads are connected to free ends of the transverse branches. Coupling of the components to one another is effected by male and female components, the male components having both screw threads and channels to engage a female component having either lugs or compatible screw threads.
