How to replace the toilet: step by step instructions on replacing the toilet with your own hands
Plumbing in the bathroom fails quite often. The reasons for this may be many, but the outcome is always the same - the equipment must be replaced. This is where the main question arises: how to replace the toilet with your own hands with high quality and without unnecessary movements?
Good preparation is the key to successful work. Get the necessary set of tools, related materials and detailed instructions for beginners. Following the recommendations and learning about possible errors, you will cope with the replacement of plumbing for one or two.
How to understand that it is time to change the toilet
At first glance, the wording may seem strange. Anyone can understand that the toilet needs to be changed when it is out of order. But in fact, most of the problems associated with malfunctions of the sewer system and the toilet bowl in particular, can be eliminated without changing plumbing.The following faults occur most frequently:
- flows from the tank;
- flows from under the bowl;
- cracks in ceramics;
- unpleasant smell from sewage.
If water constantly flows from your tank, this is a serious reason to think. Such wasteful use of water is contrary to the current trend of environmental protection and saving natural resources. If the tank drips onto the floor and you are tired of putting the coxae, and all the pipe joints are normal, most likely, the cause was chipped or cracked.
In this case, you can only temporarily solve the problem, but the replacement of the toilet bowl should be made as soon as possible. But if the water from the tank flows down the side of the bowl to the sewage system is good news, most likely there is no need to change the plumbing. The cause of such a malfunction is often a leaky valve. Fortunately, the entire inside of the cistern is sold separately, you can simply replace it.
Sanitary faience and porcelain are fragile materials that are not resistant to sudden temperature changes. Enamel can be covered with a grid of cracks, which not only spoil the aesthetic appearance, but also threaten to destroy the entire product.
If there are cracks or chips on the toilet, try to make a replacement as soon as possible. You never know at what point the pottery will not stand and will burst under the weight of a person, by the action of water or simply from internal stress. It is good if at this moment someone is nearby and can quickly eliminate the consequences of the disaster, otherwise you can count on the upcoming repairs in the toilet at the neighbors below.
Bad smell is another bad sign. Often the reason for this is the wrong location of sewage pipes when the drains are trapped in the sewers. But if you are convinced that everything is in order with the pipeline and you can be sure that the earthenware is clean, look for the reason for the destruction of the glossy ceramic coating.
If the enamel is corroded and the porous sanitary ware began to contact with dirty drains, it will soon begin to absorb and absorb unpleasant odors. Remove them will not work, such destruction - the process is irreversible. There is no complete replacement of plumbing.
Another reason to change the toilet - repair in the toilet. Few people want to leave the old plumbing with a complete change in the design of the bathroom. This is certainly a pleasant excuse. New models of plumbing appear regularly, and it is difficult to keep up with the fashion. You choose a classic model or an unusual copy from the fashion catalog - the replacement will be carried out on the same principle.
What you need to prepare in advance
Before you change the old toilet with your own hands, you need to prepare for work. Especially carefully you need to think about everything if the replacement is carried out in the toilet, which continue to use. In this situation, plumbing needs to be replaced quickly, and without proper organization it is impossible. Choose the right model, prepare all the necessary tools and supplies, and then you can get to work.
The choice of the type of new toilet
The most important thing is to buy a new toilet. Then, depending on your choice, a set of tools and materials for replacement will be selected. There are such types:
- floor standing;
Outdoor more common, and the choice of models of different classes is very wide. Replacing an old floor-mounted toilet with a new one is the most common story. There are floor models such as "monoblock", "compact", separate bowl and tank, as well as with a hidden drain system.
Monoblock is a product that combines both the bowl and the tank. The toilet compact is when the tank and the bowl are delivered in a set and are connected during the installation process (the most popular option in our market is sanitary products). The retro model, when the tank is located under the ceiling and is connected to the toilet by a pipe, and to drain it, you need to “pull the string” less and less. It looks good in the interior of the appropriate style.
Modern version - hidden drain system. To replace a conventional toilet bowl with such a one, it will be necessary to build a false wall, behind which a cistern with the installation system will be hidden. Externally, these models look very neat, there is only a drain button on the wall, and all communications are hidden.
Hanging bowls are not installed on the floor, they are hung on special anchor bolts on the wall. Thus, under the bowl remains free space that can be used with benefit. And from a hygienic point of view, this design wins. It is easy to clean the floor under the wall-mounted toilet, and dirt is often collected around the floor.
One more detail that is important to consider when replacing a toilet bowl with your own hands is the direction of release. There are 3 types:
- angle release;
A popular option is the straight horizontal release. The toilet is connected to the sewer pipe on the same level. Oblique issue was used in the Soviet high-rise construction, but is found today.
But devices with vertical discharge are installed more often in America and China. Convenience lies in the fact that the toilet can be put at any point, communications are brought inside the interfloor overlap. We have this possible in private homes.
A set of necessary tools for work
A set of sanitary tools to replace the old standard toilet. Depending on the condition of the old equipment, which will have to be dismantled, and the sewage pipes, as well as on the chosen method of fastening the new plumbing fixture, the set of necessary tools may vary slightly.
Prepare the following required items:
- adjustable wrench;
- hacksaw or grinder;
- sealant gun;
- hammer and chisel;
- rubber spatula;
- building level;
- personal protective equipment (glasses, gloves).
A puncher will be needed to knock out holes in the concrete under the dowels, to which the new toilet will be mounted. An adjustable wrench makes work on connecting the water supply. To tighten the screws you need a flat or Phillips screwdriver, and to seal the joints - a gun for a cylinder with a sealant.
Hammer and chisel can be useful if the equipment was connected to the old Soviet sewer riser from cast iron. To the bowl was set smoothly, use the building level.
Related materials that will come in handy.
In addition to a set of tools for replacing the toilet with your own hands, you need to purchase additional materials that will be needed during installation:
- corrugation to connect to the riser;
- pipe to connect to the water supply;
- FUM tape;
- mounting kit.
In any sanitary issue the moment of sealing is paramount. Any gap or loose connection threatens to leak.
To connect a sanitary device to the sewage system, you need to buy a special plastic corrugated pipe. This is convenient because the pipe is flexible and suitable in most cases. It can be bent to any position, stretch and compress.
For sealing compounds using sealing tape or tow - the old-fashioned way. The fixing kit for replacing the toilet includes dowels, screws, bolts, washers, nuts, plugs for connecting all components and installation. Do not be alarmed if something is missing, all this can be bought separately.
How to dismantle the old toilet
To replace the old toilet with a new one, you must first disassemble the equipment. If the plumbing is not too old, most likely, there will be no problems with dismantling. Another thing, if the plumbing is actually very old, and sewage pipes are cast-iron of the Soviet type. Here it is necessary to sweat. But first things first.
If everything is not so bad, and the toilet is not so ancient, it will be easier to replace it:
- Shut off the water supply. Drain the tank.
- Prepare a bucket and rags.
- Disconnect the tank by unscrewing the bolts from the bottom.
- Remove the corrugation or plastic eccentric that connect the outlet of the bowl to the sewer.
- Remove the remaining water from the bowl with a regular sponge.
- Look at the fastenings on the sides of the base. They should be 2 or 4. Unscrew them with a wrench.
- Using a knife, remove the silicone sealant from under the base.
- Remove the bowl from the tile.
In the last century, they tried to make repairs “for the ages”, thorough. And plumbing installation was no exception.
Toilets can often be found in apartments, planted on mortar, embedded in a screed, rewound at the base with rags and covered with several layers of paint. At the same time, the connection with the pipe is smeared with a thick layer of cement. Now it seems ridiculous, until you face the replacement of such a rarity in person.
If you don't mind ceramics, you can dismantle it in parts. It will come in handy hammer and chisel. Knock around the connection of the bowl with the pipe, while rocking the mount. If it does not give in, strike boldly on the neck of the toilet bowl, it will crack. Now it can be removed.Just do not hit the cast iron pipe with a hammer, it is also very fragile and can crack.
Installing a new plumbing fixture: what needs to be considered
When the old toilet is successfully dismantled, it is time to replace the plumbing with a new one. The installation process is different, depending on the type of model selected. The mounting of the bowl with floor mounting and the mounted model with a concealed cistern is carried out by different methods. Step-by-step installation instructions will help you do the job with your own hands.
Compact toilet - step-by-step installation workshop
In order to replace the old toilet on the floor type "compact", if the installation will be done on the tile floor, follow our recommendations.

- When you have decided on a place, circle the base with a washable marker. Mark marker attachment points.
- Clean the plumbing aside. On the floor were all the necessary marks. Take a drill with 12 drill and drill holes in the tile. Concrete is better to beat a drill with a drill number 12.Insert the dowels in the holes.
- Take a flute or cuff, which you will connect the issue with the sewage system. Install it in place, missed the place of the joint sealant.
- Put a new toilet with a corrugation in the correct position. Slide the bolts into the mounting lugs and screw them in with the adjustable wrench. Do not overdo it, so as not to pinch and do not split ceramics.
- Connect the toilet to the sewer. Treat all joints with silicone.
- Place the tank on the bowl. Bolt the elements.
- You can connect the device to the water supply.
Check all joints and threaded connections for leaks. If everything is normal, you can begin to use the plumbing.
It is simpler to replace such floor toilet, than to describe process by words. Modern models are designed so that the floor covering is not damaged.
Installation: mounted bowl and hidden tank
Replacing the usual toilet on the wall with a hidden cistern is much more complicated than the previous version.Here it is not just the replacement of equipment, but also the repair of the flooring, and the construction of false walls, followed by tile or other materials.
A detailed description of how to change the usual toilet on the wall structure:
- Mark the installation location. 110 mm sewer pipe and water supply pipe are brought to the selected site.
- Try on a purchased installation (hard frame for installation). Decide on height. Standard placement is 450 mm from the floor to the seat and 100 mm from the floor to the bottom of the bowl.
- Marker to mark the attachment to the floor and wall, so that they exactly coincide with the mounting holes.
- Punch holes and install the frame. Make sure the installation is correct using the level.
- Connect the water to the flush tank.
- Included with the installation is a plan to cut a sheet of drywall to sew up the installation site.Drywall fasten to a metal profile and directly to the installation. It is better to use moisture resistant materials.
- Make the finish at your discretion.
- It's time to replace the toilet bowl itself. Connect it to the sewer corrugation to connect to the pipe. Do not forget the sealant.
- Screw the bowl straight to the frame-installation through tile and plasterboard using studs.
- Connect the device to the sewer and drain tank.
Despite the fact that the replacement of the toilet on the wall will take more time, it's worth it, because such plumbing looks expensive and stylish.
How to avoid common mistakes
Replacing the toilet in the toilet with their own hands and not making mistakes is difficult, especially when there is little or no experience with plumbing. We have collected a number of the most common plumbing errors that novice masters allow when replacing toilets. This list will help you avoid unpleasant surprises during the installation process.
So that the water in the sewage system does not stagnate, it is necessary to observe the slope. The construction rules and regulations say a slope of 3-5% in the direction of the riser.If you decide not just to replace the toilet, but to move it to a new place, do not forget about this rule. When you rearrange the bowl 1 meter further from the riser, you need to raise it by 3-5 cm. And so on every meter. Then problems with drains will not arise.
Some rush to change the toilet at the very beginning of the repair in the toilet. If possible, this should be avoided. The reason is that the faience plumbing is very fragile and with further construction work in the toilet too likely to damage it. Change ceramics last.
If a bidet is installed in your bathroom, the flush-mounted toilet should be flush with its top edge. Then the plumbing looks harmonious and more convenient to use it.
Replacement of sewage pipes must be accompanied by the installation of audits. Access to the inspection doors in the walls should always be free, since there are aesthetic doors for sale for this purpose.These rules cannot be neglected, otherwise you may find yourself in an extremely uncomfortable position during a maintenance or emergency situation.
