Selecting the ideal toilet for your bathroom renovation or construction is essential not only for comfort but also to make sure it works well with your plumbing system. The type of outlet a toilet has is one of its less talked-about but crucial features; it controls how waste is discharged from the toilet into the sewage system. Knowing the various kinds of toilet outlets will enable you to choose wisely and save expensive repairs to your current plumbing system.
Typically, toilets have one of two primary types of outlets: vertical, also called a floor outlet, and horizontal, also called a wall outlet. Which one you choose will mostly depend on how the plumbing in your bathroom is laid out. For example, you would need a toilet with a horizontal outlet if your drainage pipe was set into the wall. On the other hand, a vertical outlet would be more appropriate if the plumbing in your bathroom passes through the floor.
In addition to horizontal and vertical outlets, there is another less popular kind called a skew outlet. This type of outlet is especially helpful in some architectural scenarios where it would not be possible to have only horizontal or vertical outlets. By choosing the right type for your space, you can avoid the additional costs and labor associated with rerouting your plumbing. Furthermore, knowing these choices can aid in optimizing space, especially in smaller bathrooms or during extensive renovations.
We’ll go more into each kind of toilet outlet in this post, going over benefits, drawbacks, and the best uses for each. This will help you choose the best kind for your house, guaranteeing a hassle-free and practical bathroom arrangement.
| Type of Toilet Bowl Outlet | Suitable Case |
| Horizontal Outlet | Ideal for modern homes where the plumbing is designed to go through the wall. |
| Vertical Outlet | Best for older buildings or ground floor installations where the waste pipe needs to go downwards into the floor. |
| Diagonal Outlet | Useful in situations where there"s a slight angle needed, often found in renovations or non-standard installations. |
Slanted outlet
Toilet bowl outlet obliquely
The toilets with oblique outlets in "Brezhnevka" and "Khrushchevka" buildings are the most popular models; the outlet device in these models has an angle of 30–40°. Direct connections are common in brand-new, modern buildings; however, in these situations, using sanitary products with an oblique outlet is perfectly acceptable.
Benefits of the model:
- very large selection of modifications;
- affordable cost of sanitary appliances;
- maximum simplicity of self-connection;
- possibility of connection to various types of outputs.
The configuration’s primary drawbacks are:
- unsuitability of the design for connecting suspended models;
- a fairly high risk of sewer odors;
- probability of splashing during flushing.
The ease of self-installation of the device may be one of the benefits of WCs with oblique outlets, in addition to their diverse model range and complete universality. An eccentric, flexible corrugated hose, a plastic transition elbow, and waterproof silicone sealant are used to complete the connection.
Horizontal
Models of WCs with horizontal outlets can be installed with special spigots in the presence of a sewer pipe that has an oblique angle in its outlet. In order to conserve space and give the sanitary device the most aesthetically pleasing appearance possible, it is installed in close proximity to the wall. The toilet bowl is connected using standard sleeves.
Benefits of the model
- guaranteed repairability;
- affordable cost of sanitary devices;
- quite decent performance characteristics;
- the possibility of installation to corner devices with oblique outlet.
The primary drawbacks of the setup are:
- the need to adapt corrugated adapters;
- The probability of rewiring the sewer socket;
- certain difficulty in self-assembly.
Horizontal outlets come in floor, suspended, and attached type models these days. There are certain drawbacks to parallel arrangement as well, such as the inability to install independently, the possibility of regular blockages, and the potential for leaks to occur where the sanitary device and sewer system meet.
The type of bowl outlet—horizontal, vertical, or angled—determines how the toilet will connect to the plumbing system in your house, so keep that in mind when selecting a toilet. Vertical outlets are appropriate for older buildings where the waste pipe passes through the floor, while horizontal outlets are perfect for the majority of modern homes since they extend straight into the wall. Angled outlets are flexible and can be used with a range of plumbing configurations. To guarantee a seamless installation and ideal bathroom layout, choosing the appropriate toilet outlet type requires an understanding of your home’s current plumbing configuration.
Universal
The toilet outlet’s functional universal design includes a feature that allows sewage and household waste water to be drained away using various components that transition into the wall or floor. In restrooms equipped with universal outlets, the outlets are situated horizontally at the back of the unit. These models typically have a notably higher price.
Benefits of the model:
- operational comfort;
- absence of unpleasant sewer odors;
- maximum convenience of independent repair work;
- possibility of use with different variants of sewers.
The primary drawbacks of the setup are:
- the need to use adapters for installation in the floor or riser;
- high cost of imported sanitary products;
- some maintenance problems.
Sanitary appliances with a universal outlet are effectively utilized in a variety of sewage systems because of their design features. Universal outlets are very popular because they allow for easy and quick independent connections and come with well-chosen adapters.
Toilet bowl outlets that are commonly used
Floor outlet
The vertical placement of the outlet section makes it possible to install the toilet bowl in small sanitary rooms even when there is not enough available space. The siphon and spigot that are already integrated into the product itself is the configuration that differs most from the others. The fact that these models are not wall-mounted explains why there are multiple methods for installing them.
Benefits of the model:
- optimal design for a private home;
- the possibility of installation almost anywhere;
- masking the sewage main under the floor;
- maximum convenience of revision and repair of the outlet part.
The primary drawbacks of the setup are:
- unsuitable layout of the sewage system;
- expensive professional repair and installation services;
- quite high cost of the sanitary ware itself.
The model range with floor outlet has many unquestionable benefits, such as ease of placement selection, compact installation, the creation of enough room for the installation of additional furniture and sanitary appliances, high flushing system efficiency, no water splashing during the flushing process, and the structure’s guaranteed strength and dependability.
Hanging toilet bowl
Installations these days don’t fit into the typical toilet bowl models, so there are frequently issues with their connection. A metal frame is used as a support structure when installing suspended plumbing fixtures in order to secure the flush cistern and bowl. Only the toilet bowl and cistern button are visible due to installation and finish; the piping system of the frame and block designs is hidden by finishing materials.
Benefits of the model:
- operational comfort;
- practically silent operation;
- No unattractive appearance of the risers;
- The possibility of selecting a device to match the overall style.
The primary drawbacks of the setup are:
- Difficulty in selecting the optimal connection scheme;
- high cost of the sanitary appliance;
- complexity of revision and maintenance.
An extensive connection diagram for the sewer pipe is included with each set, and installation issues may arise from the toilet outlet’s placement, which is totally incompatible with the Tee’s inlet hole. In these circumstances, a flexible branch pipe is used to connect the suspended model to the sewerage network. Although the corrugation lengthens the outlet section, which is not always required when installing the installation, it does allow you to connect elements that are situated in different planes.
Selecting the appropriate toilet bowl outlet type can have a big impact on your bathroom’s long-term functioning as well as the installation process. Knowing the various kinds of toilet outlets is essential whether you’re building a new bathroom or remodeling an existing one. The three primary varieties—the S-trap, P-trap, and the less popular Skew trap—are appropriate for various plumbing configurations and spatial arrangements.
For bathrooms with floor drainage, which are frequently found in older buildings, the S-trap is perfect. Where space and pipe routing permit, this type guarantees a clean and effective plumbing system. Conversely, modern homes with plumbing that exits through the wall are better suited for the P-trap. Because of its simplicity of installation and compliance with contemporary building codes and practices, this type is preferred. The Skew trap is a less common type that may require special fittings for those who live in older homes or have specific spatial challenges.
When choosing a toilet with the right kind of outlet, take into account your home’s current plumbing setup as well as the area physically surrounding the toilet. Speaking with a qualified plumber can help you make the most compatible and effective decision by offering advice and suggestions that are specific to your case. It’s a good idea to consider upcoming maintenance and the accessibility of parts for the outlet type of choice. A future full of expensive repairs and renovations can be avoided with careful selection and installation.
In the end, the toilet bowl outlet selection affects not only installation but also your bathroom’s long-term usability. Making an educated choice will come from taking the time to comprehend the various kinds and how they fit with the plumbing requirements of your house. This tiny change can improve your bathroom’s overall functionality and guarantee comfort and dependability for many years to come.
