Water Pressure and Diffusion

Instead of a hard jet of water or a messy, undisciplined stream, the shower head diffuses the jet of water, in so doing providing a much more comfortable and beneficiary water stream that is spread over a greater surface area, and can be further adjusted for added comfort depending upon the prerogative of the bather. A larger amount of water pressure is also achievable thanks to shower heads, and as a result a level of water conservation is possible.

Valves and Shower Head Variations

The shower valve is what governs the flow of water and determines the speed and thus the strength of the stream. While many simply believe a bigger shower head is better, this is a misconception and is not necessarily the case. A large shower head may have a less powerful valve, however, it may also diffuse the water better and more comfortably. Thus, the head and valve work together to determine the characteristics of the shower head, and the combination that works best is subjective rather than objective. Low flow shower heads provide greater water pressure with minimal quantities of water thanks to its aerating abilities. Some shower heads provide only one kind of stream of water, while others can be adjusted for various streams on the fly, to suit the bather's taste. The most common kind of shower head is the fixed shower head, which cannot change its position, except to change the angle of water by repositioning the angle of the shower head. Some fixed shower heads are recessed, while other shower heads are different altogether and act as hoses/shower handsets that can be taken out of a fixed position and stretched to a completely different one. Further, some showers feature fixed body jets, which are smaller jets of water that can come from different, fixed positions and act to further alter the climate of the shower.
