Comparison Grohe Eurosmart 33302002 vs Grohe Eurosmart Cosmopolitan 32832000

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 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 length of the hose provided in the design of the tap. This is a secondary parameter, since the hose is selected by the manufacturer in such a way that it is comfortable to use it for its main purpose — for taking a shower. But for tall people, the standard length may not be enough, so it is appropriate to know its dimensions for greater comfort and ease of use.

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.

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.
