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.
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».
