Comparison Grohe Ambi 30189000 vs Grohe Blue Pure 31299001

Types of application provided by the design of the tap.

Modern taps can be designed for bath, shower, washbasin, bidet, kitchen, drinking water filter only and with the possibility of connecting to a filter. At the same time, many models are designed for several application formats at the same time — for example, functioning with a bathtub and a washbasin at the same time; and there are models without mixing water at all (with one connection pipe) — only for cold or only for already mixed water. More details in the separate paragraphs below.

— For bathtub. Taps used to fill the bathtub. Traditionally provided for wall mounting (see "Installation"), although there are exceptions in some specific models. In addition to a bathtub, such a tap can be used for a shower and/or a washbasin; in the first case, the design provides for the connection of a shower set, in the second, a long swivel spout that can be turned from the bathroom to the sink of the nearby washbasin.

— For shower. This option means that a shower set can be connected to the tap; sometimes such units are even supplied as a set (see "Spout design"). Specialized shower taps are exclusively wall-mounted or built-in (see "Install...ation"). At the same time, in addition to “shower-only” models, there are also “multi-purpose” products designed to be used simultaneously with a bathtub, and sometimes also with a washbasin (see “For bathtub” above).

— For washbasin. Specialized taps designed only for washbasins and have a relatively short spout, usually fixed, and can be installed in almost any way (except that floor models are a rather exotic option that has not gained distribution). Due to the similarity of washbasins with kitchen sinks, some models of a similar design can also be used as kitchen taps. Another, quite common, option is a hygienic shower for use with a bidet. Also note that the “washbasin” assignment can also be provided as an additional function in taps originally designed for bathtubs (see above).

— For kitchen. Taps for this purpose can be both highly specialized and provide other applications — for a washbasin (see above) or for a drinking water filter (see below). Anyway, such products are mounted mainly on a wall or tabletop, and the spout can be made quite high so that a pan or other large dish can be placed under. Also, in kitchen taps an interesting feature as a spring spout can be found (see "Spout design").

— For bidet. A bidet is a device in the form of a hygienic bath for washing the external genitalia and anus after going to the toilet. The classic bidet tap is installed directly on such a bath in a horizontal way (see "Installation"); the shape and design of the spout in such models is selected in such a way as to ensure effective ablution. However, in addition to this, the “bidet” category also includes specialized taps for a hygienic shower — a similar procedure carried out using a separate shower set. Such taps are built into the wall and do not require a separate bidet — a hygienic shower can also be used with a conventional toilet.

— For drinking water filter. Taps designed to supply drinking water from a tap filter, usually located under the kitchen sink. They are installed exclusively on the tabletop (see "Installation"), most often on the sink itself. Specialized models with only this equipment are distinguished by their small size and single-valve design (see "Tap type"). In addition, the possibility of connecting a drinking water filter can be provided as an additional feature in kitchen taps (see above). In such models, the spout has two holes — for "common kitchen" and for drinking water; each flow is controlled separately by its own valve (set of valves) or by a joystick.

— No water mixing. Taps that are designed to supply water at the still temperature. Outwardly, such models are no different from the classic ones: some are made with levers, others with a cross handle. But the key to them is the presence of only one pipe for supplying water. Accordingly, you can connect only cold, only hot or already mixed water.

The tap type is indicated by the type of controls installed in it. A number of features of both management and application in general depend on this. Nowadays, on the market you can find single cross handle, two cross handle, single lever (including those with additional touch control), non-contact and thermostatic taps, as well as push button models, which include both self-closing and thermostatic with a button. Here are the main features of these options:

— Single handle. Taps controlled by a single rotary handle (or a lever that moves in only one plane). In fact, they are not even "taps" as such, since they cannot mix hot and cold water and only regulate the pressure of the water supplied to them. It makes sense to use single handle models where the water temperature is constant and/or it makes no sense to regulate it — for example, in models for a kitchen filter (see "Suitable for"), for a washbasin where only cold water is used, or for an English-style washbasin, where hot and cold water is supplied from separate taps and mixed in the sink.

— Double handle. The classic design of taps, which does not lose popularity nowadays: two rotary handles responsible for...hot and cold water, respectively. This design is simple and inexpensive, while being reliable, moreover, it is convenient for precise temperature control. In addition, two handle taps are not afraid of the difference in the pressure of hot and cold water, and therefore it is recommended to use them with boilers. The disadvantage of this option is the impossibility of changing the pressure separately from the temperature and vice versa — any change requires turning both valves, while the pressure and temperature can fluctuate.

— Single lever. Taps where the flow of water is controlled by a single lever. Most often, turning the joystick from side to side in such models regulates the temperature, and tilting relative to the axis of rotation controls the pressure. This allows you to adjust the temperature without changing the pressure (and vice versa) and even “remember” the selected temperature option (just lower the lever to close without turning it sideways). At the same time, such devices are less accurate in adjustment than double cross handle ones.
Occasionally, you can also find a more specific variety — single-lever taps, supplemented by a separate temperature control lever (see below). In such models, the main joystick controls only the pressure.

— Push button. Models of mixers in which the control of turning the water supply on and off is assigned to a button. The first press turns on the water flow, the second turns it off. The button can be either an auxiliary means for conveniently turning on/off the water, or the main control element for the tap. In the latter option, to adjust the water supply pressure, the button is often made rotary.

— Self-closing. A variety of taps with button activation. However, here the button works on the principle of a timer: when you press it, water flows, and then a special mechanism gradually returns the button back, blocking the flow. Closing time is selected in such a way that one press allows you to more or less effectively wash your hands. Such devices are especially popular in public places, such as toilets of cafés, shopping centres, cinemas, etc.: there is no need to worry that an inattentive visitor will forget to turn off the tap. Most often, these taps are single-temperature, but there are also models with a temperature adjustment lever (see below).

— Thermostatic. Taps that have a thermostat function — that is, capable of automatically maintaining the temperature set by the user. Such models are extremely convenient: when the pressure or temperature of the water in the pipes fluctuates, you do not need to fiddle with the settings — the device will independently select the operating mode so that the outlet temperature does not change (or at least these changes are minimal). The main disadvantage of thermostatic models is the complexity of the design and, as a result, the high cost. In addition, many of them require an electrical connection. For control, models may include rotary controls or a button (see above).

— Non-contact. Models operated in a non-contact way — without the need to touch the device. This format of operation is most popular in washbasin taps (see "Suitable for"): in such models, a sensor is used that reacts to the presence of the user's hands under the spout. This is especially convenient in common areas where it is undesirable to touch the tap once again. There are other types of non-contact models — in particular, devices for the kitchen or shower. In the first case, it can be inconvenient to open an ordinary tap with dirty hands after kitchen work. At the same time, the control may not be completely contactless — there are devices with valves or other equipment for pre-setting the temperature, while the sensor in them works only as a water flow switch. And touchless shower taps necessarily have an additional control for setting the temperature; the sensor in them reacts not just to the hands, but to the whole person.

— Single-lever + touch. A variety of single-lever mixers (see above), equipped with an additional switch. As in conventional single-lever models, the joystick in such devices is used to adjust the pressure and temperature; the difference lies in the fact that the water is opened not by a lever, but by the mentioned switch. In other words, it is enough to set the optimal pressure and temperature once using the joystick — and then you can turn on the water by simply touching the switch. The device of the switch itself can be different: in some models, the entire tap's body plays its role, in others a special button or even a foot pedal is provided. The exception is the non-contact models described above — they may be similar in design and method of use, but all the same, these taps are classified into a separate category.

— 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.

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 type of power used in a tap with electronic components — for example, a non-contact model (see Tap Type) or a backlit device (see above).

The most popular nowadays are battery-operated mixers, while some of these models may also have the ability to be powered from the mains. In addition, there are purely network devices, as well as a rather specific option — mixers with combined battery power with a generator. Here is a more detailed description of all these types of food.

— Batteries. The main advantage of such mixers is ease of installation — they do not require electricity supply from the network, which eliminates the difficulties of laying wires. However the operating time on one set of batteries is limited, and replaceable batteries usually have to be purchased separately. On the other hand, the electronic components of mixers are usually not particularly “gluttonous” in terms of energy consumption, so the battery life period is often calculated not even in months, but in years. And when buying batteries, you can choose their brand at your own discretion, and often the type: either purchase inexpensive disposable cells and change them periodically, or spend money on batteries with a charger once and avoid additional expenses in the future.

— Network. Mains power is convenient because the user does not need to monitor the condition of the batteries and periodically change them — the electronics will work a...s long as there is voltage. The downside of these amenities is, first of all, some difficulty in installation: you need not only to install a mixer, but also to find a nearby outlet for the power supply and connect the wires, paying special attention to the quality of the insulation. After all, the device will have to work in conditions of high humidity, and even direct contact with water. On the other hand, such models operate from a low safe voltage (usually about 12 V) supplied from the power supply; so even with problems with insulation, you can not be afraid of electric shock. The second caveat is that when the electricity is turned off, the mixer can become completely useless.
In general, this option is especially suitable for plumbing used in public places — for example, toilets of stations, shopping centers, etc. Mains power minimizes service interruptions (no need to change batteries); and a power outage, usually, makes useless not only the mixer itself, but the entire room where it is installed. Although, of course, nothing prevents you from choosing a model with mains power and for home use.

— Network / batteries. Taps capable of using both types of power described above. Usually, in such devices, the main source of energy is the mains, and batteries are used as a backup option in case of power outages. Thus, the mixer, on the one hand, has an unlimited service life, on the other hand, it remains operational even when the mains voltage is lost. On the other hand, such versatility significantly affects the cost, despite the fact that it is not required so often; and the main drawback of network models — the need for laying wires — is also quite relevant in this case. Therefore, mixers with combined power supply are produced quite a bit.

— Battery / generator. Quite an original option: a combination of a generator driven by a stream of water and a battery. In this case, the battery is the direct power source for the mixer electronics, while the generator is used to recharge it as needed. Thus, the power supply is completely autonomous, independent of the mains; and additional maintenance for such devices is practically not required (unlike the same battery-powered models — see above). Installation of such a mixer is quite complicated, but most often it is less difficult than installing a network model. But the unambiguous disadvantages of this option include the complexity and high cost, which significantly limit its use.

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.
