The Best Macerating Toilets

What is an Upflush / Macerating Toilet? – Pros and Cons

As the name implies, this type of toilet flushes waste upward after it is dropped into the tank. Maceration of the waste is achieved by grinding the waste so the pump can pump it through a discharge pipe. Isn’t it just super amazing? It works well and in the simplest way.

This process takes place with every flush, so no waste sits in the macerator or pump unit. This way, you don’t have to worry about keeping the toilet system clean; it can clean itself independently.

To keep in mind, only waste materials that are easily broken down should be put into the toilet. Also, not to use corrosive cleaning products that may lead to damage of the macerator. 

Upflush toilets are excellent solutions for anyone with a limited water supply or low-pressure water systems. This is the best toilet for a basement option as well, with no floor drain. 

Additionally, these systems are relatively easy and quick to install. They save more water than standard toilets because maceration helps waste flow through pipes easier. This eliminates the need to use high-pressure toilet systems, significantly reducing water usage.

Upflush Toilet FAQ:

We have gathered a list of common questions about upflush toilet systems. There are many aspects to consider, so browse through the following to ensure all your bases are covered.

Do macerator toilets work?

Macerating toilets work great. It is highly reliable because the waste is sent through a grinding (macerating) system behind the toilet before being pumped to an overhead waste line. However, standard toilets rely on gravity and water and run through a trap into a sewer line, sometimes problematic.

How much does it cost to install an Upflush toilet?

The total cost of an upflush toilet system is $800-$1200. Macerating toilets themselves cost $600-1000, as seen in our review. It will take a trained plumber 1-2 hours to install, with a rough $100-$200 for their time. Our above analysis included toilets with macerating pumps, but you will also need a sewage ejector system; these cost roughly $450-$700 and don’t come with the toilet.

How long do Macerators last?

This depends on how much it is used. For example, a basement toilet may not be your main bathroom, but expect the macerator to last about ten years if used often. With a lower amount of usage, the macerating pump should last up to 15 years. 

How far can a macerating toilet pump?

You can install macerating toilets up to 15 feet below the existing sewer line or 150 horizontal feet from a discharge area. With a 1/2 HP upflush pump, greywater, human waste and toilet paper are macerated and effectively disposed of.


There you have it, the quick guide to the top ten best upflush toilet systems on the market today.

  1. I have two questions. 1) How would your describe upFlush macerating toilet noise levels? I assume the flushing part of the toilet is same noise as regular toilet so the question is really the macerator and pump noise and duration of that noise.

    2) on a 50′ horizontal run, can that have slight up/down variations? That is, can there be a slight dip mid-way say of 18″ or does it have to be a level or declining run the whole distance? I have to go under a foundation to connect an outlying building to the sewer connections under the main house, so the run will start out declining from the out-building, then dip under the cement foundation of the house, then come back up to connect to the existing sewer.

    Great article, thank you.
