ABSTRACT:
A shield is used in combination with a wall having an outer surface and formed with a throughgoing hole having an edge and with a plumbing fixture almost entirely recessed behind the wall surface and having a control part projecting forward through the hole past the surface. The shield is elastically deformable waterproof and is formed unitarily with a cup-shaped body generally surrounding the plumbing fixture and with an annular bellows-type cuff surrounding the control part and having a rear edge unitarily joined to the body and a front edge fixed to the wall surface at the hole edge. The plumbing fixture also has a laterally projecting connection nipple behind the wall adapted to be mated with a pipe behind the wall and the body is formed with a laterally throughgoing orifice fitted tightly around the nipple. Furthermore the shield is unitarily formed with an annular flange projecting laterally from the front edge of the cuff and fixed to the wall surface at the hole edge.
