At what height should the faucet be installed above the bathtub to ensure convenient and safe operation?
When performing repairs yourself, you need to pay special attention to the installation of the mixer, because a lot depends on the location of this plumbing equipment.
First of all, it is necessary to build on existing building codes and regulations.
Types and characteristics of mixers
A mixer is an integral attribute of a plumbing system, responsible for water supply, its pressure and temperature.
Before deciding on the installation location of the mixer and the height, you need to figure out which accessory needs to be fixed.
Manufacturers offer several types of bathroom fixtures. There are three types of mixers based on the type of design.
Valve
This type of bathroom faucet is found both in residential premises and in industrial and administrative buildings.
It is considered a classic of plumbing equipment, characterized by its low price, ease of installation and repair.
They can be divided into two subgroups. The first is equipped with a faucet with a rubber gasket as a mechanism that blocks the flow of water.
The valve closes the area through which liquid is supplied to the gander.
In domestic models, the water supply process is carried out due to rotation, due to which the gasket quickly wears out, becomes deformed, and water begins to drip into the bathtub, sink or onto the floor. In modern products, the connection to the base is progressive, which ensures a tight fit without friction.
The second system has two ceramic plates made of oxidized aluminum. This is a more reliable and durable design with a long service life.
Lever 
This type is a functional and stylish analogue of a valve mixer.
Made from ceramic, plastic or metal. A special plate combined with the body serves as a joystick.
Divided into several types:
- Ball design for the bathroom is equipped with a round part with three holes for hot, cold and mixed water. The element is in tight contact with rubber gaskets. The mechanism begins to work with the help of an adjusting rod. The pressure depends on the area of the combined holes.
- Cartridge system has two ceramic plates inside. The lower part is equipped with three holes, and the upper part serves as a mixer. When you change the position of the joystick, one of the holes enters the disk chamber. Thanks to the combination, access to water of a certain temperature is opened. Silicone lubricant ensures smooth movement of the lever.
When choosing the type of mixer, you should think in advance about the location for its installation, measure the dimensions and imagine whether it will be convenient to use.
Thermostat
The main advantage of installing bathroom equipment is that it allows you to get stable heating regardless of the water pressure.
The valve located in the pipeline reacts to pressure. With a sharp decrease, the amount of cold liquid supplied to the chamber decreases.
The device consists of the following elements:
- lever;
- frame;
- spout
One of the parts has degree divisions, since it is a temperature regulator. You need to fix the required mode 
just one time.
The devices have differences in design. There is no gooseneck in the shower mechanism.
The bathroom fixture is a tubular system with a spout, a watering can and switches along the edges.
They can be placed on the wall or on the side of the bowl.
The basin faucet is a standard accessory with a thermostat that can be installed on a horizontal or vertical surface.
The shower faucet is presented in the form of a core without a watering can and a gander. All necessary elements are connected using tubes. The mixer is secured using a special container.
Installation height standards
The rules for placing the mixer and the requirements for distance from the floor are justified by ease of use. According to SNiP, the mechanism should be located 250 mm from the side of the bathtub and at a height of 800 mm from the floor.
For the sink, the parameters change upward: 1000 mm. As for the shower, everything depends on the size of the tray area; the pitch can reach from 700 to 1200 mm.
How to calculate the height from the floor?
Often the height from the floor depends on the model of the bathtub, sink or shower. As a result, the accessory is mounted too low or high.
If in the first days this is not noticeable, in the further process of operation the incorrect location will cause a lot of inconvenience.
- Before installation, it is important to choose a suitable location and visually assess maximum functionality.
- The height cannot be determined until the bowl is positioned. This is due to the fact that in many cases the font is placed on a pedestal. As a result, the adjusted distance from the floor of 200-250 mm is converted into 100 mm. Not only does the system look unsightly, but most mechanisms cannot be fixed at such a height.
- Many designs are equipped with additional parts: filters, softeners, aeronizers. The devices take up a certain space, which may affect the installation height.
- It is important to calculate the step from the sides. The possibility of positioning the sink and the need to use one device for two bowls should be taken into account. In this case, not only the parameter from the floor is determined, but also the length of the gander, so that it is convenient to turn the spout.
- Sometimes a ceramic border is laid over the sinks, which prevents the fittings from fitting tightly. In this case, the step from the floor is calculated taking into account the side.
A few years ago, choosing the location and method of installing the faucet was not a priority. All plumbing fixtures were produced according to a single standard, without taking into account the design features of the room.
Now designs and equipment are offered in intricate variations, and the owners do not always choose comfort first of all.
Selecting an installation method based on height
As a rule, the mixer is mounted to the wall, which is considered a classic and common technique.
The technology allows you to save space in small spaces. In practice, there are three mounting options.
Installation on the side of the bowl
The method has many advantages: convenient operation, the font fills faster, water does not splash, the shower hose is disguised.
In addition, fixation on the bowl allows you to use a variety of possibilities to create the desired interior.
The distance from the floor level here depends on the height of the bathtub itself, the pedestal, and design features.
But the faucet only works for the font; another device will have to be fixed to the sink.
The installation process is quite complicated; it is difficult to do without the help of a specialist.
Rack Mounting
An original and multifunctional design that allows you to stick to your chosen design. May have one or two supports.
The first option involves two internal pipelines; for the second model, the hoses are connected separately.
The height of the device can reach from 700 mm to 1500 mm. The spout, valves, regulators, and fixture for the watering can are located in the upper part of the device.
The pipes are supplied along the floor, otherwise communications will have to be installed in the corners and covered with plasterboard.
Typically, such models are equipped with all modern accessories:
- thermostat;
- tropical system;
- overhead shower.
The stand is equipped with small shelves for shaving accessories, cosmetics and hygiene products. The only drawback is the high cost.
Wall installation
The faucet can be fastened only if the pipes are embedded in the surface and brought to the connection point in advance.
The bathtub must fit tightly to the base, otherwise the water will splash and flow onto the floor.
It is optimal to place the fittings at a distance of 200-250 mm from the floor level, but please note that for use with a sink there must be a sufficiently long gib.
The step between the washbasin and the font matters.
Another option is to insert the mixer into the pipes.
Communications can play the role of additional design elements, especially if they are made of the same type of material or painted with the same paint.
Installation is simple; if you follow the technology and accurate calculations, you can do it yourself.
An important condition is that the pipes must be placed at the required height.
The bathroom faucet must be installed in the correct location, with precise height calculations. This will help avoid splashing and flooding.
A few useful tips will help you choose the optimal location for the taps and determine their comfortable placement:
- If you plan to install the device on the side of the bowl, do not do it in the center. It is better to mount it closer to the edge from which it is more common to carry out water procedures.
- Having decided on the height, it is necessary to calculate the mounting depth of the fittings and the pitch between the hot and cold water outlets (at least 150 mm).
- Regardless of installation method, a level will be required for calculations. Using this tool you can avoid some mistakes.
- It should be remembered that different types of mechanisms and methods of their installation depend on the characteristics of the area: those that fit perfectly into large rooms are not suitable for narrow rooms.
- Cold water is supplied on the right side, and hot water on the left.
- In addition to the aesthetic side of the issue, there must be a practical and functional goal. When installing, it is recommended to be guided not only by the features and nuances of the interior. Otherwise, after a few days of operation, many inconveniences will arise, the work will have to be redone, which is fraught with unnecessary costs.
If you need to use one device for a bathtub and a sink, it is important to choose a mechanism with a long spout, and first measure the step between the two types of plumbing fixtures.
Rational arrangement is the main factor when selecting and attaching cranes.
