What is a Macerating Upflush Toilet: A Comprehensive Guide!

If you’re in need of a toilet installation in a space where traditional plumbing is challenging, such as a basement or garage, a macerating upflush toilet can be an ideal solution.

This innovative type of toilet system offers unique benefits, installation flexibility, and cost-effective options.

In this comprehensive guide, we will explore what a macerating upflush toilet is, its benefits, installation guide, and overall cost, helping you make an informed decision for your plumbing needs.

What is a Macerating Upflush Toilet?

A macerating upflush toilet, also known as a macerating toilet or an upflush toilet, is a specialized toilet system that doesn’t rely on conventional plumbing for waste disposal.

Instead, it uses a macerating unit, which is a motorized device that grinds solid waste and toilet paper into a fine slurry, allowing it to be easily pumped up and away from the toilet via a small-diameter pipe.

This eliminates the need for traditional gravity-based drain lines and allows the toilet to be installed in locations where traditional plumbing would be difficult or costly, such as in basements, garages, or other areas below the main sewer line.

Benefits of Macerating Upflush Toilets

Macerating upflush toilets offer several benefits that make them an attractive option for certain plumbing scenarios. Some of the key advantages of macerating upflush toilets include:

Easy Installation:

Macerating upflush toilets are relatively easy to install compared to traditional toilets, as they don’t require major modifications to existing plumbing lines. They can be installed on any level of a building, and the waste can be pumped vertically and horizontally to reach the main sewer line.

Flexibility in Location:

One of the biggest advantages of macerating upflush toilets is their flexibility in location. They can be installed in spaces where conventional plumbing is not possible, such as basements, garages, or even in remote areas without access to a municipal sewer system.


While macerating upflush toilets may have a slightly higher upfront cost compared to traditional toilets, the overall installation cost can be lower in certain scenarios. This is because they don’t require extensive plumbing modifications, which can save on labor and material costs.


Macerating upflush toilets can be used with different types of toilets, including standard toilets, wall-mounted toilets, and even urinals. This makes them a versatile option for various plumbing needs and configurations.

What are the Installation Requirements?

To install a macerating upflush toilet, you will need to have access to an electrical outlet and a water supply. You will also need to have a location for the toilet that is close to the macerator pump. This pump can be located behind the toilet or in the wall behind the toilet.

The toilet itself is similar to a traditional toilet, but it has a special bowl that is design to hold the waste and toilet paper until it is ready to macerate and pumped away.
