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.

The shape of a complete watering can of the top shower (see «Type»). From a technical point of view, shape has some influence on shower performance: for example, at the same size (width or diameter) square upper shower will allow more water than round shower. However, in practice, the effectiveness of the shower and the sensation of its use are determined by so many different factors that the effect of the shape of the watering on their background is simply lost. Therefore, usually the choice of this parameter is solely due to the aesthetic tastes of the user or the requirements for the design of the bathroom. Therefore, in addition to the round and square form, there are oval, rectangular and non-standard.

Check valve prevents the water from moving through the mixer to the opposite direction - for example, when there is a large pressure difference between hot and cold water. This feature will be relevant for those who are going to install water meters: the presence of non-return valves on mixers is often a prerequisite for fulfilling the installation request.
