Rear Outlet Toilets: A Quick Overview

Rear outlet toilets are a specialized type of toilet that is designed to be installed against the rear wall of a bathroom. Instead of having a traditional outlet that connects to a floor-mounted drain, these toilets have a horizontal outlet at the back of the bowl that connects directly to the waste line through a wall-mounted drain flange.

Rear outlet toilets were once popular in commercial buildings and public restrooms due to their space-saving design and efficient waste disposal system. However, in recent years, they have become more popular in residential settings as well, particularly in homes with smaller bathroom spaces or where plumbing fixtures may need to be installed against an existing wall. While rear outlet toilets are not as common as their conventional counterparts, they offer many benefits, such as space-saving, easy installation, and efficient waste disposal, making them a popular choice for modern homeowners.

What are the Advantages of Buying Rear Outlet Toilets?

There are several compelling reasons why one might consider a Rear Outlet Toilet as opposed to a traditional toilet. In this section, we will outline some of the key benefits of Rear Outlet Toilets that may make you reconsider your current bathroom setup.

Space-saving design

Rear outlet toilets are specifically designed to save space in small bathrooms. They have a different configuration than traditional toilets as they have the waste outlet at the back rather than the bottom of the bowl. This design eliminates the need for a large space at the back of the toilet, allowing for it to be placed closer to the wall.

This space-saving design is particularly beneficial for bathrooms that have limited space. For example, in a small apartment or a narrow bathroom, a rear outlet toilet can help maximize the available space. By freeing up space behind the toilet, it allows for more room for other bathroom fixtures such as a sink, vanity or even a bath. Additionally, it can create a more open and spacious feel in the room, even if it is small.

Improved plumbing access

Rear outlet toilets are a type of toilet in which the waste outlet is located at the back of the toilet rather than the traditional position, which is at the floor. This design allows for improved plumbing access, as the waste pipe can be connected directly to the toilet without having to go through the floor.

This is particularly useful in situations where there is limited space, such as in a basement bathroom or in a small apartment. Rear outlet toilets are also preferred by some people due to their ease of installation and maintenance, as they can be easily accessed and serviced from behind the toilet. Additionally, using a rear outlet toilet can also help to prevent clogged drains, as the waste is discharged directly into the main drain line with a cleaner, more efficient flow.

Reduced risk of leaks and clogs

Rear outlet toilets have a different waste outlet path compared to conventional toilets. The waste outlet is located at the back of the bowl, which eliminates the need for a bend in the waste pipe, like in conventional toilets. This straight path reduces the risk of clogs, as there are fewer turns and bends for waste to get trapped and block the flow. Additionally, because the water is flushed directly into the waste pipe, there is a lower chance of blockages occurring, which can lead to leaks and sewage backups.

Furthermore, the design of the rear outlet toilet also lessens the chance of leaks. Traditional toilets use a wax ring to seal the outlet between the toilet and the waste pipe. However, wax rings can deteriorate over time, leading to leaks. Rear outlet toilets, on the other hand, use a rubber flange instead of a wax ring, which provides a tight seal and reduces the risk of leaks. Overall, rear outlet toilets are a great option for those looking for a low-maintenance and long-lasting toilet that reduces the likelihood of leaks and clogs.

Buyer’s Guides

Deciding on the perfect rear outlet toilet can be a daunting task, but there are certain elements that can simplify the process. Here are some important factors to consider before making a purchase.

Rough-in measurement

Rough-in measurement refers to the distance between the wall and the center of the toilet’s waste outlet. It is important to consider this measurement before buying a rear outlet toilet because it determines whether the toilet will fit properly in the available space and connect to the existing plumbing system.

If the rough-in measurement is not considered, the toilet may not fit properly, be unstable, or cause leakage problems. It is also important to note that rear outlet toilets require different plumbing configurations than traditional toilets, so it is essential to ensure that the existing plumbing system can accommodate a rear outlet toilet before making the purchase. Therefore, considering rough-in measurement when buying a rear outlet toilet can help ensure a successful installation and avoid costly plumbing issues.

Flushing mechanism

Flushing mechanism is an important consideration when buying rear outlet toilets. These toilets typically require more powerful flushing than traditional toilets due to their horizontal outlet design. A weak flushing system can result in clogs and odors, making it difficult to maintain good hygiene. Therefore, choosing a rear outlet toilet with an efficient and powerful flushing mechanism is important for ensuring optimal performance and preventing maintenance issues.

Furthermore, the flushing mechanism also impacts the water usage and cost. Rear outlet toilets typically use more water per flush than traditional toilets which can increase water bills. Choosing a model that is water-efficient and has a good flushing mechanism can help save on water bills and contribute to conserving one of our planet’s most precious resources, water.

Bowl shape and size

Bowl shape and size are important factors to consider when purchasing a rear outlet toilet because they can affect the toilet’s functionality and comfort. Rear outlet toilets have a trapway that is located at the back of the bowl, so the bowl shape needs to be able to accommodate this feature. Some bowl shapes may be too narrow or have a steep slope which can cause clogs and other plumbing issues. Bowl size is also important for comfort and usability, especially for larger or taller individuals who may need more space to use the toilet comfortably.

Additionally, the bowl shape and size can affect the overall design and aesthetic of the bathroom. Rear outlet toilets are typically used in commercial settings or in homes with special plumbing requirements, so it’s important to choose a style and size that fits with the overall design of the space. This can involve considering factors such as the height of the bowl, the shape of the tank, and the overall shape and design of the toilet itself. Ultimately, selecting a rear outlet toilet with the right bowl shape and size can improve the functionality, comfort, and design of your bathroom.

Material and durability

Material and durability are important factors to consider when buying rear outlet toilets because these toilets are designed to handle a significant amount of weight and pressure. The material of the toilet should be able to withstand the constant use and cleaning without cracking or breaking easily. Durable materials will also ensure that the toilet lasts for a long time without needing frequent repairs or replacement. Some of the common materials used in rear outlet toilets include porcelain, vitreous china, and ceramic.

Additionally, durability is important because rear outlet toilets are connected to a drain line that is located behind the wall. This means that any repairs or replacements can be costly and time-consuming. A durable rear outlet toilet reduces the likelihood of these repairs, which can save homeowners money in the long run. Therefore, considering the material and durability of a rear outlet toilet before purchase is crucial to ensure it can withstand the pressure and last for a long time.

Water conservation features

Rear outlet toilets are a popular choice for homeowners due to their compact size and modern design. However, before purchasing one, it’s essential to consider their impact on water conservation. Rear outlet toilets typically use more water than the standard toilets, which can lead to higher water bills and wastage of this crucial resource.

By choosing a rear outlet toilet with water conservation features such as dual flush and low flow, you can significantly reduce water usage. Dual flush toilets allow you to use less water for liquid waste, while low flow models use less water per flush overall. By investing in these features, you will not only save money on water bills but also help preserve water and contribute to a sustainable future.

Warranty and customer support

Rear outlet toilets are an important investment for any bathroom, and it is crucial to consider warranty and customer support before making a purchase. A strong warranty will provide peace of mind, ensuring that any defects or malfunctions are resolved without additional cost. Additionally, customer support can provide valuable guidance and recommendations for troubleshooting or repairs. When purchasing a rear outlet toilet, it is important to research the brand’s reputation for customer service and ensure that the product comes with a comprehensive warranty.

Furthermore, rear outlet toilets require professional installation, which can lead to additional expenses if any unexpected issues arise during the installation process. Purchasing a product with a strong warranty and customer support can alleviate these concerns, as the manufacturer will be responsible for any issues that may arise during installation or use. Ultimately, investing in a rear outlet toilet with a solid warranty and customer support can provide peace of mind and ensure that your bathroom investment is protected for years to come.

Frequently Asked Questions

What is a rear outlet toilet and how does it differ from a standard toilet?

A rear outlet toilet is a type of toilet that has a waste outlet at the back of the toilet bowl rather than at the bottom.

The main difference between a rear outlet toilet and a standard toilet is the position of the waste outlet. Rear outlet toilets are ideal for situations where a floor waste outlet cannot be installed due to the location of the plumbing or the structural design of the building.
