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.
Jet depth
Distance from the wall attachment point to the aerator. It is a characteristic that determines the “reach zone” of the faucet spout.
Divertor
The diverter is a device by which the flow of water can be switched between individual components of the system - for example, the spill (if it is present) and the shower box, or between the watering can and the upper shower. The design of such a device and the way it is controlled can be different; in modern shower systems, you can find, inter alia, such options:
— Levery. Diverters are in the form of a swivel lever; most often this lever is driven directly by a valve that switches the water flow, but in advanced models there is also an electronic working principle. In any case, lever switches are most popular in modern shower systems: they are very convenient and intuitive to operate, and mechanical diverters of this type are also very simple and inexpensive.
— Push-button. Diverters of this type have the form of a button; but its specific design depends on the features of a particular system. In relatively simple mechanical models (such a majority) the button is also made mechanical, and to switch to the shower watering can be pulled up. And switching to the other side - from the watering box to the drain or the top shower - can often be carried out not only manually, but also automatically, when the water is turned off. Due to this function, the next time the tap opens, the water begins to flow not through the shower hose, which may be in the wrong place, but through the spout or the upper shower, which usually does not cause problems. In some models..., the autoswitch can also be locked at the user’s request (usually by turning the button at the top).
In turn, in advanced electronic devices, such a diverter is made in the form of an electric button, which closes the contacts that control the valve.
— Bend. Rather rare and specific variant: the role of a lever controlling the flow of water, performed directly draining, to the base of which a shower hose is connected. This control usually works as follows: as long as the spout is perpendicular to the mixer housing (that is, directed towards the bath or pan) the water flows through it; and to switch to the shower, the pour is rotated under the mixer. Such devices look interesting, and in use convenient. On the other hand, they are quite complex and expensive, and the flow itself, for a number of reasons, is usually made quite short. Therefore, this option is not available.
— Rotate the drain + push button. The combination in one system of two divers described above. As a rule, the flush turns are responsible for switching the water between the flush and the «shower part», and the button switches between the shower hose and the upper shower. Due to its complexity and cost, this combination is extremely rare.
