The aesthetics of the shell, made in the form of a tulip, the stability and practicality of this type of sanitary ware attracts many owners of urban apartments and suburban housing. True, the cost of the device plus the assembly price with the connection somewhat cools. Do you agree? However, there is a way to reduce costs - do-it-yourself installation.
In the article we presented, varieties of a convenient and beautiful type of plumbing equipment are considered. We will tell you how to mount and fix a washbasin for a bathroom with a pedestal. For independent masters, the technology for connecting a popular plumbing bowl with a supporting leg to communications is described in detail.
Benefits of a pedestal sink
A type of shell with a pedestal or pedestal is also called a tulip because of the similarity of their appearance with the flower of the same shape and beauty.
Despite the simplicity of the design, the design options for this equipment are enough to harmoniously fit it into any modern interior.
In the EU and the USA, because of the vertical arrangement of the sewer riser, the pedestal has a beautiful round shape and is not mounted to the wall
For centuries, tulip shells are popular with people due to such positive properties:
- Versatility. A sink with a pedestal can be placed in any corner of the bathroom due to the diversity of its shape, color and size.
- Compactness. The parietal nature of the sink allows to minimize the occupied space, and the space under the sink can be used for additional shelves.
- Aesthetics. The pedestal hides unsightly sewer and plumbing communications.
- Financial availability. The material of the sinks can be different in cost, but most of the assortment is budget kits.
- Easy installation. Most models are attached to the wall with two bolts, and the pedestal is not fixed at all with fasteners, remaining sandwiched between the sink and the floor.
Most of the drawbacks of pedestal sinks are due to their workmanship: earthenware and glassware are quite fragile and susceptible to shocks, while metal and enamelled ones can change color with poor care.

Types of sinks and pedestals for the bathroom
Any sink is a bowl, which can have several holes: for the bottom drain, for installing a tap and for lateral drainage of excess water. Each manufacturer implements its own engineering solutions in the models, so there are no clear-cut options on how to install a sink with a pedestal.
Attachment classification
According to the fastening mechanism and decorative design of communications, five main types of sinks can be distinguished.
Mortise. Such a sink is mounted in a stationary countertop in two ways:
- top;
- lower.
At the upper mount, only the neck of the sink enters the countertop, and its main part is located above the countertop. With a lower arrangement, the appearance of the sink is similar to a kitchen sink, in which only the locking edge protrudes above the countertop.
Mortise sinks often have only one hole for draining water, and in this case the mixer is mounted on a wall or countertop
Outboard (cantilever) Such bowl bowls are mounted directly to the wall with bolts or with brackets. Their communications remain open from below or hide subsequently in locker-like lockers.
The advantage of hanging sinks is the presence of free space under them, which can be used to place cabinets or plumbing fixtures
Pedestal sinks. They differ from suspended ones by the presence of a special pedestal that provides additional support and aesthetically hides all communications.
Sinks with an adjacent wall pedestal can only be installed in bathrooms, in which there are no running water communications along the walls
Semi-pedestal sinks. The difference between a half-pedestal and a pedestal is that the first has a short length and does not reach the floor. The semi-pedestal is mounted independently under the sink and performs only a decorative role for hiding pipes and a siphon.
If you need a sink for a child, then the option with a semi-pedestal is an ideal solution, because it can be lowered to 60-70 cm
Furniture. Sinks of this type have an individual form of fixtures, which is suitable only for the furniture that comes with them.
Designer sinks usually do not require fixing to the wall, but are installed directly in the furniture set using special fasteners
Most furniture sinks are expensive and are made only by renowned brands.
How to choose a sanitary sink for installation in the bathroom by size is described in detail in the article, which we recommend that you familiarize yourself with.
Varieties of shell material
The cost of products largely depends on the appearance of bathroom sinks and the material of their manufacture. You can buy a cheap enameled sink, but it certainly won’t add beauty to the bathroom.
Each sink coating has optimal care products that protect the surface from scratches while maintaining cleaning properties.
The most common materials for modern sinks are:
- Faience. The cheapest and unassuming material most plumbing is made of. Its disadvantage is a discoloration of the coating and the appearance of microcracks after several years of operation.
- Porcelain. Unlike faience, porcelain undergoes a two-stage burn, therefore they have a more snow-white coating, the color of which practically does not change over the years.
- Porcelain Tiles or fake diamond. The advantage of this material is its strength, stable parameters of the external coating and ease of removal of coloring substances when they hit the surface.
- A natural stone. This is an expensive image material, the shells from which it is rational to install in the interior of natural materials. Its disadvantage is the presence of microcracks on the surface, which is why it is almost impossible to remove the coloring matter that has fallen onto the surface.
- Glass. Glass sinks can be made in any color. They are more expensive than faience, but cheaper than artificial stone. Water stains are strongly visible on the glass surface, therefore, to maintain its beauty, you must regularly wipe the surface with a cloth.
Production of sinks from steel, copper, plastic and other materials is possible. Their shape can be round, square, angular or oval.
Dismantling old plumbing
In the case of installing a new sink instead of old equipment, it is important to know the sequence of steps to remove old plumbing.
During the dismantling of the sink, it is advisable to wear clothes that are not afraid to spoil forever, because the spray of sediment from the siphon contains a lot of grease and dirt
When dismantling the old shell, work is carried out in the following sequence:
- Overlapping water, and tap valves are unscrewed.
- It is removed if there is a pedestal.
- The fastening of the mixer at the bottom of the sink is unscrewed and the tap is removed.
- The siphon is unscrewed from the neck of the sink, water is carefully drained from it.
- The siphon pipe is pulled from the sewer opening, which is closed with a special cork or plastic bag to block unpleasant odors.
- The nuts that fix the sink are unscrewed, and it is removed.
When installing new plumbing, it is advisable not to use old flexible water hoses and a siphon, which can leak during re-installation due to worn rubber gaskets.
Installation of a sink with a pedestal
Having finished dismantling the old plumbing and cleaning the room, you can begin installing a new sink with a pedestal. Next, step-by-step instructions for this process will be considered to better understand the nuances of installation.
Regardless of the design and individual features of the model, the installation of a sink with a pedestal and the connection of communications are carried out in the standard manner:

Step 1: Fitting the sink to the installation site and marking
Step 2: Marking the points for installing the mounting studs
Step 3: Drilling the holes for the studs
Step 4: Screw the sink into the dowel
Step 5: Install the bottom valve in the sink drain
Step 6: Screw the fasteners into the fixing points
Step 8: Assembling the sink mixer
Step 8: Connecting the mixer to the water supply
Step one: Determine the height of the sink. According to SNiP, the height of the upper edge of the sink above the floor should be 80-85 cm. But for tall people it can be increased to 90-95 cm, and if a separate sink for children is installed in a large bathroom, then the height can be reduced to 65-70 cm.
The specific level is decided at the family council, based on the wishes of each person. After the final selection of the height of the sink, a strictly horizontal line is drawn on the wall, which is checked using the building level.
It is necessary to determine the level before purchasing equipment, since changing the height of the pedestal can only be done by completely replacing the plumbing kit in the store
Second step: fitting the sink. A pedestal is placed under the wall, on which a sink is put on top. Its upper edge is aligned with the level drawn on the wall, after which places for drilling mounting holes are marked with a marker at the bottom of the sink. Then the equipment is removed to the side.
When trying on, it is necessary to check the level accuracy in both horizontal planes so that there is no tilt of the bowl towards the wall
Step three: installation of rods for hanging the sink. In the designated places, holes are drilled to a depth of at least 700 mm. The wall should be made of dense material, and not crumble under the influence of a drill. Unreliable septa can lead to sinks and foot injuries.
After drilling holes, the corresponding dowel lengths are inserted into them. Then it is necessary to screw in special holes on which the sink will dress
It is better to screw anchor bolts into strong concrete walls. They are somewhat more expensive than ordinary dowels, but fixing with their help is an order of magnitude more reliable
Fourth step: re-fitting the sink. Similarly to the second step, the equipment is tested with regard to the screwed fasteners. If the fasteners are located correctly and the horizontal level is observed, then the sink and pedestal are set aside.
For a more snug fit of the shell to the wall and to avoid chips, you can apply a strip of silicone along its rear perimeter
Fifth step: Install a siphon and faucet on the sink. In order not to suffer from a lack of space when installing the faucet and siphon on the already installed plumbing, it is easier to do this before attaching the sink bowl to the wall.
Each plumbing product is accompanied by a diagram and the sequence of its installation, so screwing the sewer siphon and tap should not cause difficulties. It is not necessary to lubricate the joints on the openings of the sink with a sealant; in these places, rubber gaskets should be sufficient for sealing.
Connecting to the sewer and installing the siphon is carried out in the following order:

We install a decorative cover on the drain pipe, with which we will subsequently close the connection unit to the sewage system, seals and nuts to fix the connections. On the opposite side, we put a seal and put the nozzle in a siphon
To connect to the drain from the sink, we collect the second pipe, on which we also put the gasket and nut
We unfold the siphon so that it takes a vertical position, put an O-ring on the upper thread. In our example, the siphon is not connected directly to the drain, but is connected to a fitting with a branch for the overflow pipe. A washer will be connected to the siphon pipe
Trying not to move the seal, carefully tighten the connecting plastic nut by hand. Do not use the tool here, so as not to damage the plastic parts
To connect the washer, remove the plug from the siphon pipe and put a fitting in its place, to which a drain hose will be connected
The fitting designed to connect the drain hose is positioned at an optimal angle. The nut, like all previous connection elements, is not yet tightened, then to adjust in fact
We check the vertical position of the siphon, if necessary, correct it. Then tighten all the nuts in the joints to the stop
We connect water, we check the tightness of the joints and the operation of the siphon. If everything is fine, install a pedestal
Step 1: Assembling the drain pipe to connect the sewer
Step 2: Assembling the connection pipe to the sink
Step 3: Laying the gasket in the drain siphon assembly
Step 4: Tighten the union nut on the fitting
Step 5: Installing the fitting to connect the drain of the washing machine
Step 6: Attach the fitting with a nut without tightening
Step 7: Correcting the position of the siphon and fixing
Step 8: Installing the pedestal to mask the knots
Sixth step: installation of a sink and connection of communications. A sink with a dressed siphon and a tap is hung on the mounting bolts. Between the bowl and the wall, as well as in front of the fixing nut, special soft pads are put on the rods. They prevent chips from ceramic coating when tightening fasteners.
The nuts are slightly tightened by hand, after which they begin to connect the hoses to the water pipes and sewers. After connecting the communications, a test opening of the water is carried out.
The siphon drain pipe should be greased with a thin layer of silicone before being inserted into the sewer - this will facilitate the process of sticking in and seal the connection better
Seventh step: Installation of the pedestal. If there are no leaks in the system, then you can substitute the pedestal under the hanging sink. The final tightening of the fixing nuts must be done after aligning the edge of the sink according to the horizontal line drawn on the wall.
Plumbing is ready for use. For decor, you can cover the seam between the sink and the wall with white sealant.
Features of the installation of the semi-pedestal
If a semi-pedestal is chosen as the equipment that closes the communications of the sink, then you need to know about the differences in its installation from the installation of the classic “tulip”.
If the semi-pedestal comes with a sink, they can be mounted on a single bracket bolted to the wall
The first six of the above steps for fixing the sink to the wall and connecting the communications remain unchanged.
Further actions must be carried out in the following sequence:
- Since the semi-pedestal has its own fasteners, after installing the sink, it is necessary to try on the product against the wall and mark the places for drilling holes for the bolts.
- Drill a wall with a drill and insert it into the holes of the dowel.
- Attach a semi-pedestal and screw it to the wall with bolts, placing rubber gaskets between the product and the wall, as well as in front of the fixing nut.
The mass of the sink cannot be transferred to the semi-pedestal, so there is no need to try harder to screw it to the wall.
