Comparison Grohe BauEdge 31367000 vs Hansgrohe Focus 31817000

— Straight. Spout that have straight or almost straight shape and directed almost horizontally (other arrangements are highlighted in a separate paragraph — see “At right angle”). Generally, such a spout combines simplicity, practicality, and versatility. In particular, it can be of any length, and can also be rotary (see “Spout”), while being inexpensive to manufacture. Nowadays, straight spouts are extremely popular, and in almost all types of taps (see “Suitable for”). The exception is perhaps the kitchen application: this form is inconvenient for washing dishes by itself and leaves less space for dishes in the sink than other shapes (for example, angled or gooseneck spouts).

— Gooseneck. Taps with a spout in the shape of an arc, usually semicircular and rather steep. This design is most popular in kitchen taps, as it provides the necessary space for washing large dishes. Many models with such a spout are designed for washbasins — they also use a vertical installation, for which the arc is very convenient. And gooseneck bath taps are most often original premium models installed directly on the side of the bath (also horizontally).

— L-shaped. Spout in the shape of the letter “L” — with a vertical base and a horizontal “crossbar” extending from it. Thanks to this shape, the spout can be positioned at a sufficiently high height, which is especially conveni...ent when used in the kitchen or with a washbasin. Most of the L-shaped models refer to these specialization options (see “Suitable for”). According to the type of the tap (see the corresponding list), they are usually single-lever, while the joystick is located on the side; however, there are other options — both in the location of the joystick, and in the type of control.

— U-shaped. Spouts of this category resemble L-shaped models (see the relevant paragraph), in which the end of the spout is noticeably bent downwards. This gives them an original shape, as well as some resemblance to gooseneck models. U-shaped spouts are typically taller and are intended for use in kitchens or washbasins. At the same time, they are not as popular as the mentioned L-shaped ones, and even more so the gooseneck ones. In particular, because of the higher cost with no obvious practical advantages (although this form may well be optimal in terms of design).

— S-shaped. A variant that is predominantly found in bath models (including bath and washbasin solutions) as well as in some kitchen taps. The spout in this arrangement has the shape of the letter “S”, laid “on its side”. This design is well suited for wall-mounted models, where the spout outlet must be placed noticeably below the tap itself.

— At right angle. A straight spout located at a right angle relative to the tap body — directed from the base of the body up or down. This shape is especially suitable for washbasins and kitchens, and it is mainly found in taps of those specializations (see “Suitable for”). Most models with a similar spout have a fairly modern appearance, thanks to that they fit well into modern, high-tech interiors, etc.

— Curved at an angle. A spout that leans upward from the base of the tap and curves slightly downward at the end. The shape is in many ways reminiscent of the “at right angle” option, but it has its own characteristics. Firstly, such a spout can be made somewhat longer, which is convenient for kitchen use: the outlet is at a sufficiently high height and there is enough space under it to wash even large dishes without any problems. Most of the models in this category are just made for the kitchen. Secondly, for some users, this form is preferable from an aesthetic point of view (although, of course, this is a matter of personal taste). These spouts look more “cheap” compared to the products of the “at right angle” form factor and are extremely rare among top plumbing brands.

— Vertical jet. This type of spout is found among bidet taps. It involves vertical spraying of a water jet for taking a hygienic shower after visiting the toilet. The mortise vertical spray module is installed separately from the tap. Usually, the design also assumes a water return valve.

— Connected to overflow. Taps with a spout in the form of a flexible hose that connects to the overflow of the bathtub, and the water is poured through it. Thanks to such taps, minimalism is ensured in the appearance of the bathtub, which is caused by the absence of a classic spout. In addition, there is no need to make extra holes in the side of the bathtub to install the tap.

An angle to turn the drain. It is worth considering that in our case the angle is not considered relative to the center position, but the overall angle is right-left. In this way, the 110 degree value allows to rotate the mixer slurry with respect to the center position by 55° to the right and left.

Distance from the fixing point (for vertically mounted taps) or from the centre of the mounting hole (for horizontally mounted taps) to the middle of the spout. It is a characteristic that determines the "reach zone" of the tap.

The jet height is usually specified for taps with horizontal installation (see "Type of installation"). It is measured from the base of the tap to the spout outlet. The large height of the spout is important primarily for kitchen models (see "Suitable for"), because it allows you to place large dishes in the sink. This parameter is directly related to the height of the spout (see above): the height of the jet cannot be greater than the height of the spout. Thus, in fact, one has to find a compromise between the height of the jet and the dimensions of the tap, especially if there is little space for its installation.

The angle of the water jet produced by the tap, relative to the vertical. Generally stated for full head; with partially blocked water, this angle is smaller. Anyway, the water jet is usually directed towards the user, and the greater the angle of inclination, the farther from the spout the point of incidence of the jet will be placed. However, in most cases this point is not critical; problems can arise only in very cramped conditions, with small basin sizes.

The diameter of the cartridge used in the tap.

The cartridge is called the "heart" of the tap — the part directly responsible for adjusting the pressure and/or temperature of the water (in some models — also for switching between spout and shower). The main dimension of this part is precisely the diameter. However, in fact, this size becomes relevant only if it is necessary to replace the cartridge. But when choosing a tap, it does not really matter — from the point of view of characteristics, only the overall dimensions of the device depend on the diameter of the cartridge, and then quite approximately and without a fundamental difference between individual models.

The maximum water flow during the operation of the tap, in other words, the maximum amount of water that it can pass through in a minute. This characteristic is important, foremost, for models designed for baths (see "Suitable for"): the greater the throughput, the faster the bath will fill. However, the meaning of this paragraph is not limited to this. First, flow information can be useful in certain calculations related to water supply — for example, to calculate the required pump capacity. Secondly, high-end taps can be equipped with aerators to achieve a powerful and efficient jet with low water consumption; the consumption indicated in the characteristics allows you to evaluate the efficiency of such devices in comparison with analogues.

The lowest inlet pressure at which the tap is able to fully perform its functions of unhindered water supply.

The highest inlet pressure at which the tap is able to operate in a trouble-free mode with minimal risk of premature failure. In other words, this is the ultimate strength of the tap. Note that for normal east european use, it can be assumed that the maximum pressure in the water supply is 6 bar. One should focus on that value and choose a model with a small margin of max pressure in order to avoid leaks in the tap nodes during pressure surges in excess of the norm. Note that in plumbing with a centralized water supply, the pressure can reach 10 bar. Therefore, for expensive taps that make high demands on the inlet pressure, it is necessary to buy special reduction gears.
