Late or early, but there always comes a time when the owners of an apartment living space have to change the plumbing equipment, which has either already served its due date, or is outdated and does not meet modern trends in appearance or functionality. And most of the questions here will concern the arrangement of the bathroom, namely the selection of a mixer for the shower. The overwhelming majority of compatriots will choose this element of plumbing, focusing solely on the price. However, it will be necessary to take into account both the design and the installation method, and, in fact, the design of the mixer itself. It is quite possible that the plumbing has already been purchased, and it is simply impossible to connect it due to design features.
They differ in the way the water is supplied. On this basis, they can be conditionally subdivided into three groups:
Such models are known to everyone. They are a handle that regulates the force of the jet and the temperature of the supplied water. The basis of the mechanism is a cartridge consisting of two plates with holes. The jet supply head and its temperature will depend on the area where they are combined. But, as practice has shown, the acceptable setting of such a mixer sometimes takes a lot of time. Moreover, the cartridge is an extremely fragile part of the structure. It is most affected by the quality of the water, and the resulting plaque and corrosion lead to its breakdown. The main disadvantage: due to a failed cartridge, the entire mixer will have to be replaced. But still, the low price of these models, as well as the ease of their installation, allow single-lever equipment to remain in trend until now.
They represent a crane. Equipped with two levers - one for cold water, the other for hot water. With their help, both the pressure and the temperature are simultaneously regulated (by increasing the supply or cold / hot water to the total flow). This type of equipment has other names: "axle-box crane", "axle-box crane", "two-valve", "valve head".
In turn, they can be divided into two types:
They can be called a technological innovation in the plumbing market. They themselves represent a panel with a pressure / water temperature regulator and buttons for switching it. There are mechanical and automatic models - the former are manually controlled, the latter are equipped with an LCD screen. It is worth mentioning non-contact views - they are equipped with a photocell, which is installed in the spout of the faucet and reacts to the obstruction of the view by foreign objects (hands) and produces a predetermined volume of water of a certain temperature. Such samples are usually installed in cafes, government agencies, in transport engaged in mass transportation (railway, air, long-distance buses).

Summing up the review of existing models, the question immediately arises: which mixer is better? Based on modern realities, it is possible to say for sure that THERMOSTAT. And here are the reasons:
IMPORTANT! It is always worth remembering that thermostatic models will cost 3-4 times more than their younger counterparts. Moreover, a layman is unlikely to cope with their installation.
The plumbing in question may also differ in the way you switch between a shower head and a simple spout. The following switching systems exist:
The considered options for switching between a shower and a conventional tap can be installed both inside the general mixing system and outside.The former take up less space and are easier to manage, but if they fail, they will require a complete replacement. The latter look rougher, but are much simpler to install and easy to repair.
The most popular at all times was the long type of spout. This option is very good when the washbasin is located next to the bathroom, because in this case you do not have to install an additional tap.
When choosing a model, you need to pay attention to the angle of movement and the swivel mechanism - this is the most flawed part of the structure, as well as the length of the crane - 30 centimeters is considered a normal length.
The shortened type of spout appeared later, when in the USSR they began to build small-sized housing, where there was no washbasin in the bathtubs. And nowadays it looks good in small bathrooms.
The watering can is one of the main elements of the entire system. The comfort of a person in the process of taking a shower directly depends on it. Watering cans can be metal and plastic. The latter are much cheaper, but the former have a long service life. They can also differ in the type of water supply - it can flow in trickles or drops. Everything here will depend on personal preferences and financial capabilities.
The bathroom faucet with shower can be fixed in the following ways:

No matter what expensive and functional model a potential buyer would prefer, he should definitely look at what material it is made of and what material it is covered with. Often, the wrong choice can lead to rapid wear and tear of all seemingly new plumbing. Below will be considered the most commonly used materials and their main qualities.
Consumer polls show that people in the post-Soviet space prefer brass or bronze (i.e., copper alloys) most of all. The reasons are usually the following:
From a large list of manufacturers, the following brands can definitely be distinguished, which are deservedly popular with buyers:
IMPORTANT! Asian manufacturers should be mentioned separately - their equipment is the most short-lived and cheapest, although it can be packed in a beautiful wrapper. Public confidence in such products is very low.
Reliable model made of brass with minimal lead inclusions. It is very popular due to its low price. The body is reliably protected from rust, the smooth running of the handles is ensured by rubber seals. The water flow is soft, which is achieved through the use of a silicone aerator. With its help, water consumption is reduced by 30%.

The traditional design of the product is successfully combined with increased functionality.The sample is still considered a budget option, because the valve heads are made of ordinary stainless steel and have standard wear resistance, which in conditions of poor-quality hard water can cause breakdown. At the same time, the design does not require a complete replacement, which is a definite plus.

The popularity of this model is due to its relatively low price. The service life of the equipment is increased by at least 30% from the standard due to the use of a ceramic cartridge of 35 mm. To soften and balance the water flow, a proprietary Perlator aerator is installed. He is also responsible for setting the temperature. The design provides for vertical mounting.

Based on the analysis of the market segment of sanitary faucets for the shower, the following conclusion can be drawn - the single-lever model remains the most popular in the middle class, where the switch between shower and spout is regulated by a cartridge. The preferred material is stainless steel, despite its heavy weight. Crane-axle models are already in less demand - they were almost replaced by thermostatic ones. Western firms are leading among manufacturers, domestic ones are slightly inferior to them, while the Asian manufacturer is hardly considered seriously. In terms of the frequency of purchase of mixers, retail chains are still leading, because the price between them and Internet sites does not differ much.
