Were you aware that 98% plus of the world’s toilets flush solely on the physics of gravity? So what do you do if you need a toilet in an unconventional location where it cannot use gravity to flush? There is no doubt about it; toilets make the world a much more sanitary place. They neatly handle the unpleasant task of transporting human bodily waste safely and neatly out of homes and businesses. There is a type of toilet that can even be located below the plumbing level and does not need gravity to help it flush. These types of toilets are called macerating toilets. In this article, we will do several reviews of the best macerating toilets.
We will also provide you with information on how macerating toilets work. This knowledge will greatly help you should you ever have the need to purchase one of these unique types of toilets. Enjoy our macerating toilet reviews!
What Exactly Is a Macerating Toilet?
A macerating toilet is a specialty toilet that does not rely on gravity to transport human waste as most conventional toilets do. They use a set of grinding blades to liquefy human waste and then they pump that liquefied waste to a plumbing drain line that will then deposit it into a septic or sewage system.
These toilets are mainly designed to be used in situations where you want to put a toilet that is either below the plumbing drain level in a building or you have to make long vertical plumbing run to connect to the main plumbing line. These toilets enable people to now put a toilet where it was never thought to be possible before. Owning a macerating toilet has many benefits to consider.
How Does a Macerating Toilet Work?
We just gave you a hint as to how a macerating toilet works. It is actually a whole lot more complicated than what we quickly informed you of. Here is an overview of how a macerating toilet works from start to finish.
To start off with it must be noted that most macerating toilets look exactly like gravity flush toilets. They have a bowl that sits on a pedestal and a toilet tank portion that rests on the back of that pedestal too. They even have standard toilet seats installed over the bowl. How they differ in looks has to do with how they flush.
They do not sit on top of a sewage drain pipe but instead have a large pipe that comes straight out of the back of them. This pipe is very short in most situations and immediately goes into what is known as the maceration chamber. This pipe and box are visible and that is the only way you can tell that a toilet is a macerating toilet model.
One other significant difference in the looks of these types of toilets is that they have to have a dedicated electrical connection that goes into the maceration chamber. Often times this wire is very slightly visible when looking at the back of the toilet.
Macerating toilets flush just like regular gravity flush toilets. They have an incoming water supply line that fills up the water storage tank on the back of the toilet. When someone uses the toilet after they are done they simply activate the handle and the flushing process starts.
The water rushes out of the toilet water tank and quickly fills the toilet bowl with water. This large amount of water is bigger than what the air in the toilet trap can hold back so it allows the water and the solid and liquid matter in the toilet bowl to go out the drain.
This is the first place in a macerating toilet where they operate differently than gravity flush toilets do. The water does not drain out the bottom of the toilet like on conventional toilets. The drain line that runs through the toilet’s pedestal base does not go all the way to the floor. This allows the wastewater to instead drain out of the back of the macerating toilet and into the maceration chamber.
When enough water enters the maceration chamber after the flush it trips a sensor located inside the unit. Once this happens the grinding process starts on any solid waste that is inside the maceration chamber.
These grinders or cutters run for anywhere from 15 seconds to 1 minute depending on the model of the macerating toilet. When they are done all the solid waste that entered the chamber will now be a liquefied slurry mix.
Once the grinders and cutter stop their maceration cycle the maceration units drain pump will then kick in automatically. This pump is strong enough to push the liquid slurry upwards or vertically to the nearest drain line that uses gravity to dispose of toilet wastewater.

Best Macerating Toilet Reviews (Updated List)
Here are some reviews of the best-selling macerating toilets:
1. Liberty Pumps ASCENTII-ESW Macerating Toilet
This is a very good macerating toilet from Liberty Pumps. It has a very sophisticated set of cutting heads and is one of these easier models of macerating toilets to installing. This toilet even looks so good it’s hard to tell it is not a regular gravity flush toilet.
This toilet has an elongated bowl configuration that makes it more comfortable to sit on when you use it and it helps clean the bowl better when it flushes too. It also includes a toilet seat with your purchase and it’s a streamlined design so it’s easy to clean.
We liked the fact that this is a water-saving toilet. It only uses a small 1.28 gallons of water per flush. It’s also easier to service than many other models of macerating toilets because it has a removable service panel so you don’t have to disconnect the plumbing to work on it.
There were a few concerns we had with this macerating toilet. The first is the fact that it is very noisy when performing its maceration function. The other thing we did not like about this model toilet is the manufacturer recommends you replace the blade in the macerating unit each year.
2. Saniflo 023 SANICOMPACT 48 One-piece Toilet with Macerator
Saniflo is the undisputed leader in macerating toilet technology. This model toilet is a compact edition of their great functioning full-size toilets. It measures only 15.75” H x 14.5” W x 18.25” D. That means you can put it in just about any free space in your room you can partially stand up in.
The maceration unit in this model conveniently stores right under the bowl. It easy to plumb and you just need to have an electrician hook up a 115V line to it when the plumbing is done. It even comes with a decorative toilet seat with brass hinges.
You have to love the compact size of this toilet. It will fit where many other toilets won’t. This toilet does not have a high tank on the back portion of most toilets. That means you can make a bathroom in such tight places as underneath a set of stairs or a room that the ceiling slopes dramatically toward the outer walls.
The seat height with this toilet can be a little uncomfortable for taller people. Another thing that some users complained about is a foul odor coming out of it if it sits unused for more than a week.

3. Saniflo SaniBEST: Macerating UpFlush Toilet Kit
Saniflo makes their regular size macerating toilet with a few different bowl styles. This one comes with a more convenient type of elongated bowl. Most people feel elongated toilet seats are more comfortable and that style bowl cleans easier during a flush.
This also meets the EPA standard as a water-saving model toilet. It only uses 1.6 gallons per flush. You can also hook up an additional sink and shower to it to have their wastewater conveniently drained through this toilet too.
One of the best things about this model toilet is it can be mounted on a wall in order to hide the maceration unit and improve the looks of the bathroom it is installed in. All you need to do to accomplish this is to order the optional extension pipe you can buy with this toilet model.
This maceration unit will jam easily if anything but human waste and toilet paper gets in it. You also have to be able to put up with a little noise from this unit for about a minute after solid waste is flushed down it.
4. Saniflo SaniPLUS: Macerating Upflush Toilet Kit
This is Saniflo’s regular-sized toilet that has a standard round front toilet bowl. That means that it sticks out from the wall about 2 inches less than their elongated bowl models. This is also a sleek looking toilet that is very versatile in the type of bathroom décor you can pair it with.
This unique model macerating toilet is also rated as an EPA-certified water-saving toilet. It uses just 1.6 gallons per flush. The maceration is automatically activated when it senses that the toilet has been flushed. That means this toilet takes no more effort to flush than any regular gravity flush toilet.
This is another Saniflo toilet that you can purchase an extension pipe for it and then mount the maceration unit behind the wall. This will greatly improve the looks of the bathroom. This toilet can also be conveniently installed up to 15 feet below the existing plumbing line in your home or business.
We did take note of a few things that consumers would like to see improved with this model toilet. If it’s not used for a while a little odor can build up in your bathroom. If it was built to automatically flush once a day this problem could be eliminated. The water in the bowl is a little too low to get a clean solid waste flush every time.
5. Saniflo Saniaccess 2 Upflush Macerator Toilet Kit
This toilet is more compact than some of the other regular style Saniflo toilets we have reviewed. You still get all the same nice benefits that you get from any other Saniflo toilet model. It will save you money on your yearly water bill and it will also nicely chop up any flushed bodily waste with its ½ horsepower macerator.
You would probably not choose this model toilet to put in a very modern style bathroom but in most other bathroom situations it will look just fine. It does feature a very smooth contoured surface that is very easy to clean.
We really like the compact design of this model toilet. It makes it a perfect toilet to install in a half-bath that is located below the regular plumbing drain line in your home or business. Its dimensions are 29.8” H x 20” W x 30.2” D.
This is another macerating toilet that is a bit noisy when it is cutting up the waste that is flushed down it. You need to consider that if you want to put it next to a child’s bedroom. We think the design of this toilet is not as aesthetically pleasing as some of the other Saniflo models.
How Do You Install a Macerating Type Toilet?
The toilet bowl and toilet tank combination on a macerating toilet install the same way that a conventional toilet does except for one big exception. That is they do not have to be placed over a conventional roughed in drain line (there is no one available that is why you are installing this type of toilet). They are still bolted down to the floor like conventional style toilets.
One of the nice things about macerating toilets is you do not need a drain under the toilet to operate them. That also means you never have to break up the floor to install one of them.
There are basically two ways that these toilets can be installed.
This is the type of installation where the maceration unit is simply placed on the floor near the back of the toilet. When you install the toilet this way you just need to hook up a very short drain line from the back of the toilet to the maceration chamber. The bad part is when the maceration chamber is installed this way it can detract from the looks of the bathroom. Usually, that is a small trade-off to have the convenience of having a bathroom close by.
Behind the Wall Installation
People who choose this type of installation do not want to see the somewhat unsightly maceration chamber resting on the floor behind the toilet. Hiding the maceration unit behind a wall dramatically improves this type of toilet’s appearance.
In order to do this, you will need a pipe extension that goes from the back of the toilet through the wall and into the maceration chamber. Of course, you will have to do this before you enclose the wall in a new home or you will have to take out a section of wall in an older home to be able to do this. When doing this you want to make sure you leave an access panel so you can easily get to the maceration unit to clean or repair it if necessary.

Macerating Toilet FAQ’s
Here are a few questions about macerating type toilets that we get asked all the time:
Is it ok to change all of the toilets in my house to macerating type toilets?
The answer to this question is a firm no. The reason for that is under most circumstances it is not necessary or prudent to use macerating toilets. They perform best as an occasional use toilet such as one located in a basement playroom or a remote office in your detached garage.
The reason for this is these toilets have some very sophisticated inner workings in the maceration chamber. The more you use these toilets the more likely they are to get clogged or need some other type of maintenance upkeep. So they are best used as convenience just a few times a day. It is worth noting that with macerating toilet installation people have no choice but to use them as their all day and all night toilet. So it’s not that they can’t do the job, it’s more of why risk it if you don’t have to.
Can macerating toilets grind or cut up such things as chewing gum, sanitary napkins, and dental floss?
The answer to this question is an emphatic no. As a matter of fact, you never want to put anything into a maceration type toilet except for natural human body waste and specialized toilet paper.
These are sensitive pieces of machinery and anything that goes into the toilet stands a good chance of clogging them up.
Macerating toilets certainly are not practical in most instances where a gravity flush toilet will work. They can, however, be the handiest toilet in the world when you need to put a bathroom in a place that is below the plumbing level or is far from the nearest plumbing line.
As we did the best macerating toilet reviews it became clear to us that you can do so many things with these model toilets. They even come in all shapes and sizes just like regular toilets do too.
These toilets have some minor drawbacks to them but nothing that is a deal-breaker. That is especially true if you really want to install a toilet in a place where you need to take the wastewater upwards in order to get rid of it. With how well they work you can now put a toilet just about anywhere in your home or office that you want to have one.
