Size
The size of the manual or hygienic shower head can be found (cf. «Complete»), which is equipped with a shower system. In fact, it implies the size of the working area - the area on which the nozzles for water supply are located. If this area is round or square, its size is indicated by diameter or width, for other shapes - by length.
Big size allows to cover more space at once; on the other hand, more compact models are more efficient, and cheaper, all other things being equal. And hygienic watering cans, taking into account the specifics of their use, by definition are made
small.
Spout
— Cascade. In such vents, water is fed through an outlet in the form of a thin horizontal slit, or a wide trench (depending on the model). Due to this, the output achieves a large width of the jet at a low thickness, which provides a good throughput, as well as the original look, imitating the waterfall (hence the name). On the other hand, this form is less universal than the classical one, and it is much more expensive, and therefore is used quite rarely.
— Classic. Models in which the spout is made in the form of a tube. Such flows may have different shapes in length (straight, curved, with an angle) and cross-section (round, triangular, square, etc.), but they are all tubes.
In most cases, there is simply no drain for shower systems.
Swivel spout
Ability to turn the spout from side to side. In this way, you can change the location of the water jet, which can be useful in many different cases.
