Shower heads and shower handsets come in a huge variety of designs. The first thing to understand is the difference between the two: A shower head is fixed to the wall and fed by a rigid pipe, which can either be exposed (in front of the wall) or concealed (behind the wall) A shower handset is movable and is fed by a flexible shower hose. It is fixed to the wall when not in use by attachment to a riser rail. The shower handset, shower hose and riser rail are collectively referred to as a shower kit. In all cases, they may be for a specific shower brand, e.g. Mira, Aqualisa or Triton or they may be universal and designed to work with any shower.
