Size
The size of the overhead shower head supplied in the set (see "Complete set"). For round watering cans, this paragraph indicates the size, for other shapes - the length (the largest of the two main sizes).
The larger the overhead shower - the more space it covers, the easier it is to "fit entirely" under the jets and the higher the throughput can be (see "Water consumption overhead shower"). On the other hand, the cost of a watering can directly depends on the dimensions. As for specific figures, the size
up to 20 cm is relatively small, although such watering cans are very popular due to their availability and low consumption. Models
21 - 25 cm can be classified as medium,
26 - 30 cm - relatively large, and the largest watering cans for the overhead shower have dimensions
of more than 30 cm.
Tilt angle
The top shower angle is tilted in both directions. Not all models have adjustment, and even those in which it is constructively laid have different angles. By itself
the ability to adjust the inclination angle of the upper shower allows you to adjust the flow of water to the desired side for the needs of a particular user.
Hose length
The length of hose for the shower head be supplied with a shower system of one type or another (see above). In most modern models, this parameter is about 140 - 160 cm - it is enough that even a tall man could easily rinse completely, from the top. In addition, some hoses can stretch 20-30% of their original length. So in practice, it is worth paying attention to the length of the hose except in special cases - for example, if the system is bought for a very spacious bathroom and you need a shower with an increased «radius of action».
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.
