What is an Upflush Toilet?

An upflush toilet, also known as a macerating toilet, is a type of toilet that uses a macerating pump to grind up and flush away waste. This allows the toilet to be installed in areas where a conventional gravity-fed sewage line is not available, such as in a basement or on a second floor. Upflush toilets are a good solution for adding a bathroom to a home where it would be otherwise difficult or expensive to install a traditional toilet. They are also relatively easy to install, as they do not require extensive plumbing work.

Over the past decade, the popularity of the upflush toilet in North America has increased. Upflush toilets allow anyone to create a bathroom in tight spaces (such as a basement) or places that don’t permit pipes. You can even set up temporary commodes for renters and long-term visitors with upflush toilets.

An upflush toilet makes it possible to install a bathroom anywhere you want, without having to add new pipes. You can hire an installer but installing it yourself will take only 4 hours, even if you are a total beginner. Upflush toilets have a simple appeal. By rethinking the way toilets work, the Upflush system allows you to easily install a new bathroom without spending a fortune.

Upflush toilet systems can be an effective way to add a bathroom in a location where a traditional gravity-fed sewage line is not available. They work by grinding up and macerating the waste, which is then pumped out of the toilet and into a sewage line or septic system using a small motor. These systems are typically reliable, but it is important to follow the manufacturer’s instructions for installation and maintenance in order to ensure proper operation. It is also a good idea to have a plumbing professional install the system to ensure that it is done correctly.

The only thing that makes an upflush toilet work differently from a standard one is the pump. The pump is small and white and can be found on the floor behind your toilet or connected to an extension pipe that hides it behind a wall. Your toilet will look almost identical to a standard system if you choose this option. For installation, all you need is an electrical outlet.

Overall, upflush toilet systems can be a convenient and effective solution for adding a bathroom in a location where it would be difficult or costly to install a traditional toilet.

How Does an Upflush Toilet Work?

An upflush toilet works by grinding up and macerating the waste using a small motor and a macerating pump. Upflush toilets are designed to be installed in areas where a traditional gravity-fed sewage line is not available, such as in a basement or on a second floor. They are a good solution for adding a bathroom to a home where it would be otherwise difficult or expensive to install a traditional toilet.

The main difference is that traditional toilets flush down into the drain gravitationally. An upflush toilet, on the other hand, discharges out of the back into a macerator tank and pump tank. This shreds the waste and then pumps it up to your stack.

Here’s how it works.

  • The toilet flushes out the waste into a macerator. The macerator is located in a small tank that sits on the floor, just behind the toilet. The macerator turns on automatically when you flush the toilet. It uses a rapid-cutting blade to turn waste into a fine slurry. When they were first invented in Europe in the late 1950s, upflush toilets were called grinder toilets.
  • The waste is moved by the pump around the macerator. The waste is then pushed through 3/4″-1″ PVC pipe (note: this is a small amount for what you’re doing, but it’s amazing! It then flows to the main stack where it will discharge normally.
  • The macerating tanks are empty. The tank is now empty except for the water that remains behind the water seal.

Upflush toilets function in the same manner as regular toilets. They attach to your sewer to flush out waste. They can travel anywhere, unlike traditional toilets. Also, they are affordable and won’t cost thousands to put in.

Add a Sink and Shower to your pump for a full bathroom.

You can add a bathroom to your home or make it a full-fledged bathroom with a sink, shower, and bathtub. You can do it with an upflush system.

Multiple fixtures can be attached to the toilet pump, making it possible to make a complete bathroom. Make sure to get the correct type of pump.


Upflush toilets can be used for both residential and commercial purposes. Upflush toilets are ideal for homeowners who want to increase their property’s value (such as the SaniACESS3 model), or for rental properties (SaniBEST PRO) that require little maintenance. They can also be integrated into commercial establishments and allow for extended usage. The SaniCUBIC 2 grinder pumps, which are similar to the SaniCUBIC 2, are powerful enough to pump multiple fixtures at once between a building.

These Upflush systems are so well-engineered that there is no limit to their potential applications.

What An Upflush Toilet Is Not

Upflush toilets are not composting toilets. Although many people mistakenly confuse upflush toilets for composting toilets at first, this is mostly because they are both relatively new designs in America. An upflush toilet is not a traditional gravity-fed toilet. It does not rely on gravity to flush waste out of the toilet and into a sewage line.

What is the difference? Composting toilets make use of decomposition and evaporation in order to dispose of waste and provide composting benefits. An upflush toilet, however, is exactly the same as the toilets you already love. It only runs on a different system.

Although there are many other upflush toilet companies, none of them have the same history, budgets for research, product line, or performance as Saniflo. Although they may have very good brand names, they don’t actually make macerating pumps. Instead, they use outdated technology and design them as upflush toilets.


An upflush toilet is a great option if you are looking to build that dream bathroom. How an upflush toilet works can be a practical and efficient option. Whether you are working in a tight space, renovating a closet or basement bathroom, or if you need to add a second bathroom.
