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 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.

A diverter is a device that switches a water flow between spout and shower head. The design of such a device and the way it is controlled can be different, in modern taps you can mainly find the following options:

— Button. Diverters of this type have the form of a button; but its design depends on the characteristics of a particular tap. In relatively simple mechanical models (most of them), the button is also made mechanical, and to switch from spout to shower, you need to pull it up. And switching in the opposite direction — from a shower to a spout — can often be carried out not only manually, but also automatically, when the water is turned off (see "Features — Shower / bath auto switch"). In some taps, auto-switching can also be blocked by the user (usually by turning the button in the up position).
In turn, in advanced electronic devices, such a diverter is made in the form of an electric button that closes the contacts that control the valve.

— Lever. Diverter in the form of a rotary lever. Most often, this lever directly controls the valve that switches the flow of water. This design is considered somewhat less reliable than push-button, but it is much simpler and cheaper, which makes it very popular — especially in relatively inexpensive taps. But in premium devices, this type of diverter can operate according to other, more advanced principles — for example, a lever can work as an electronic switch.

— Turning the spout. A r...ather rare and specific option: the role of the lever that controls the flow of water is performed directly by the spout, to the base of which a shower hose is connected. Such a control, usually, works as follows: while the spout is perpendicular to the tap body, water flows through it, and to switch to the shower, the spout turns, being under the tap. Such devices look interesting, and are convenient to use. On the other hand, they are quite complex and expensive, and the spout itself, for a number of reasons, is typically made quite short. Therefore, this variant has not gained popularity.

— Removable. A diverter located outside the body — usually between the tap itself and the spout. Typically, on one side of such a device there is a control element (most often a small lever or a rotary tap), and on the other, a pipe for connecting a shower hose. And the name "removable" suggests that this part can be easily removed if needed — unlike, for example, push-button or lever solutions, which are usually built directly into the tap body and are very difficult to dismantle or replace. Accordingly, after removal, the diverter can either be replaced with another one, or removed altogether by connecting the spout directly to the tap. This is the main advantage of this option: in case of malfunctions in the diverter, it can be removed without any problems for repair or replacement, while the tap (with the exception of the “shower part”) remains fully operational.

The type of water pipes the tap is designed for.

— Hoses. With a flexible connection type, polymer tubes (hoses) are used to connect the tap to the water supply, which can bend well and are reinforced with a metal mesh for strength. This ensures ease and versatility of attachment — thanks to the flexibility of the pipe, it can be carried even in cramped places. On the other hand, such a supply is less durable and reliable than a rigid one. It is mainly used in models for kitchens and sinks (see "Suitable for"). Installation pipes may be included in the package of the tap; this point should be clarified separately.

— Rigid pipes. Such taps are designed for installing directly to metal water pipes. The advantage of this type is reliability and strength, the disadvantage is significant restrictions on the installation site: you either have to put the tap where the pipes were made during construction, or redo the communications, which is associated with great inconvenience and cost. On the other hand, such taps are usually used for bathtubs and showers, and in modern bathrooms, typically there are no problems with unsuccessful installation of pipes.

Type of additional finishing provided in the tap. This item can specify several options — this means that this model is available in different design options. And if the finishing material coincides with the body material, this means that there is virtually no additional coating; this is found, in particular, among taps made of stainless steel, which itself is quite resistant to corrosion.

In modern taps, the following types of finishing are used: granite, chrome, chrome with granite, chrome with gold, matte chrome, stainless steel (glossy or brushed), brass, nickel, copper, bronze, gold, as well as brushed in one color or another. Here are the features of each option:

— Granite. Granite is characterized by a pleasant appearance, moreover, it is available in an abundance of different colours, allowing you to choose a tap for the design of the kitchen. Of its advantages, it is worth noting high durability, absolute resistance to corrosion and good sanitary characteristics (prevents the growth of bacteria). The main disadvantage is the high...price.

— Chrome. Chrome plating is applied to metal surfaces primarily for corrosion protection; it has a characteristic shiny (almost mirror-like) appearance. Chrome provides high resistance to oxidation and damage, yet looks good and is inexpensive — as a result, it is one of the most widely used coating materials. Its main disadvantage is the tendency to get imprints on it over time; their removal is associated with certain troubles.

— Chrome/granite. The combination of chrome and granite finish in one product. See above for more details about the features of each of these materials, but here we note that their combination implies the presence of different types of finish in different parts of the tap. Thus, the design acquires a more original and stylish appearance, greater hygiene and resistance to contamination than pure chrome, while being cheaper than pure granite. And from the point of view of the overall design of a bathroom or kitchen, it is this combination that in some cases turns out to be the best option.

— Chrome/gold. The combination of chrome finish with individual "gold" sections. The features of chrome are described above, and the "gold" elements give the product a rich appearance, while a fairly large number of buyers prefer this combination to the “solid gold” finish.

— Matte chrome. A matte variation of chrome finish (see above). On such a surface, dirt, and prints are much less noticeable than on a classic glossy; in addition, it may be more suitable in design or simply more pleasing to the eye than glossy. At the same time, the creation of matte surfaces is associated with certain difficulties, and therefore they are relatively uncommon.

— Stainless steel (glossy). Stainless steel finish is generally similar in characteristics to chrome — it is durable and resistant to corrosion. However, such a surface is somewhat different in appearance and for a number of reasons it is used mainly in premium-class models — including taps made entirely of "stainless steel" (such models, in fact, have no finish).

— Stainless steel (brushed). Similar to matte chrome, such steel is more resistant to dirt than glossy (see above), otherwise it is completely identical to it.

— Brass. Brass coating is most often combined with a body made of the same material (that is, there is actually no special finish in such a tap). One of the advantages of such a surface is a pleasant golden hue, which is especially suitable for retro-style taps. At the same time, the cost of such products for a number of reasons turns out to be quite high, besides, they are prone to the appearance of hard-to-remove prints. Therefore, they are quite rare.

— Nickel. In terms of characteristics, nickel finish is similar to chrome and is used for the same purposes, however, for a number of reasons, it is much less common than chrome.

— Copper. Finish of characteristic reddish color. Copper can give an “old” look even to a modern product, and for retro-style taps, it can be simply irreplaceable. On the other hand, this material is expensive, in part because it is difficult for copper to provide sufficient corrosion resistance.

— Bronze. Bronze is an alloy based on the copper described above and is used similarly — mainly to provide an authentic look to retro-style taps. The main difference between the two materials is the color — the bronze is somewhat darker, and the red colour is not as pronounced in it (although specific shades in different models can also be different). In addition, this material is easier to make resistant to corrosion, so bronze products are much more common than copper ones.

— Gold. Yellow alloy finish to imitate the look of gold. It is used to give the tap a rich appearance, while at the same time it is expensive in itself, as a result of which it is used mainly in premium models — in order to emphasize the level of the product even brighter. On the practical side, like any material of this level, it is characterized by high resistance to oxidation, but resistance to pollution and ease of cleaning can be different (although in most cases these indicators are also on top).

— Brushed. A brushed finish that is applied specifically to give the product a certain color — most often black or white, but other options are also found. Accordingly, the main advantage of this option is a non-standard appearance: with paint, you can achieve colors that are not available with other types of finish. At the same time, any paint perfectly resists corrosion, and the differences between different models of taps with such a finish are mainly in durability and scratch resistance. These characteristics, usually, directly depend on the price category of the product.

The warranty period claimed by the manufacturer for a certain tap model is the period during which the manufacturer guarantees the normal operation of the device. The specific terms of the warranty may vary, however, usually, it covers factory defects and malfunctions caused by the fault of the manufacturer or seller and discovered during normal use, without violating the rules; if such defects or malfunctions appear during the warranty period, the manufacturer undertakes the obligation to correct the situation at its own expense — up to replacing the tap with a working one.

Nowadays, you can find taps with a guarantee of 4 years, 5 years, 7 years, 10 years and even 25 years. In general, the longer the warranty period, the more reliable the product is, the higher its overall quality, ceteris paribus, but the more expensive it will cost compared to analogues.
