Conventional toilets rely on gravity to get rid of the waste or direct it to the drain pipes that lead to the sewerage line. But in some cases, these conventional systems might not work for you, and it is in such instances that finding the best macerator toilet becomes a priority.

The macerator toilets are unconventional toilet types that make use of a macerator that grinds down the refuse into a liquid and a pump that flushes it upwards to the drain pipe.

These types of toilets come with many benefits with key among them being they save you money as you do not need to install new piping, they are flexible as they can be installed anywhere and most are more eco-friendly since they are typically built to use less water.

The only drawback with these toilets is that they can be harder to get as they are not as common as the conventional types. However, here we help make finding one effortless with top 10 macerator toilet reviews and a handy buying guide.

What To Check Before Buying Macerator Toilet?

To make sure you get the best macerating toilet, here are the most important things to consider when choosing.

1. Types of Bowl: Elongated or Round

One of the first and most important things to consider when trying to find the perfect macerator toilet for your home or establishment is the bowl type. And here you will generally need to choose between the elongated and round bowls.

Here the choice will often boil down to your specific preferences because while some people prefer a more traditional elongated style, others find the round types perfect.

With that said, it is important to note that the elongated types tend to take up more room and might not be ideal for those with smaller bathrooms. However, these bowls are also more comfortable.

Round bowls, on the other hand, will take relatively less room, which makes them more space-saving, but they are relatively less comfortable.

2. Max. Depth of Operation

In many instances, the macerator toilet will be installed below the elevation of the sewer line, and hence before choosing one you need to make sure that it can flush upwards to the level of the plumbing line for an effective drain.

The maximum depth of operation is what will tell you how low from the sewer line you can install the toilet. And the deeper the macerator toilet can work, the better, as it means you can comfortably use it even in your basement.

While different toilets will come with different maximum depths of operation, you should aim to get something with upward of 15-feet depth of operation as you will be able to use it from almost anywhere.

3. Supported Distance

The supported distance is another important factor that you need to take into account when shopping for the best up flush toilet.

The refuse will not only have to go up from the toilet but also across a pipe before it gets to the sewerage system, and hence the pump has to be powerful enough to cover both distances.

For the supported distance, look for something that supports a horizontal distance of at least 150-feet.

4. Comfort

Like any other toilet type, your macerator toilet needs to be comfortable to work well for you. And when it comes to comfort, there are several things that you will need to take into account.

These things include the shape of the bowl and the material used to make it. For the shape, elongated bowls will typically be more comfortable than the round ones. However, a larger round bowl can still be quite comfortable.

And when it comes to the material, something made with a smooth and sleek surface will always be the most comfortable.

5. Macerating Pump

The macerating pump plays one of the most crucial roles in a macerator toilet which is to direct the refuse to the sewerage line and is hence a crucial element that you should never overlook.

When choosing a macerator toilet, it is vital to make sure that you pick something with a highly efficient macerating pump to ensure maximum efficiency and effectiveness.

Look for something with a powerful pump that runs on at least 1/2-horsepower motor like Saniflo Two-piece SaniPlus. Also, make sure that the pump has sturdy seals like the stainless steel ones as they are more robust and durable. And if the macerating pump is super quiet, the better.

6. Water Consumption

Even if you live in a place with unlimited water supply, you still need to check how much of it you use because the higher the consumption the more you pay.

And because the toilet is one of those places that you can use up a lot of water, you need to be keen on the water consumption of the macerator toilet you choose.

Most manufacturers will typically indicate the number of gallons that their macerator toilet uses per flush, and the smaller this number is, the better.

A macerator toilet that uses around 1.6 gallons per flush is often good enough, but if you can get a model that uses even less like the Liberty AscentII-RSW that will only use 1.28 and still works well, it will be an even better buy.

7. Installation

Although the macerator toilets are often easier to install than the conventional gravity ones, the ease of installation will still vary from one model to the other. Hence, before you buy one, you need to make sure that the installation will be easy enough for you.

A macerator toilet that comes with some comprehensive and easy to follow instructions and the required hardware will give you an easier time, and even inexperienced homeowners will not have any difficulties mounting it.

Also, note that with these toilets, there are two types of installation which are the standard and behind the wall installation.

Standard installation is the easier of the two, and it entails simply placing the toilet on the floor and hooking the maceration chamber with the back of the toilet using a short drain line.

Behind the wall, macerators will take more effort to install as they are the kind that will have the maceration unit behind the wall for better aesthetics, and here you will need a longer pipe extension to connect the toilet and macerator.

How to Properly Install a Macerating Toilet? Step-by-Step

How to Install a Macerating Toilet

While our macerator toilet reviews and buying guide above will help you find a good model for your home, you still need to install it properly to get the best service from it.

Although the actual installation will depend on the specific model that you have and you hence have to follow manufacturer instructions, here is a breakdown of the generic steps involved in the installation for most of these toilets.

Step 1: Prepare What You Will Need

The first step is to prepare everything that you will need for the installation.

This will require you to ascertain that your macerator has all the necessary hardware, and you should also ensure that you can easily access the vents, water supply, GFI breaker, and toilet water supply.

Step 2: Connect Discharge Pipe

The next step is to disconnect the discharge pipe, and here you need to be keen when doing things as you have to ensure that you only use 45 or 90-degree turns.

And once the discharge pipe is in place, you need to check whether it is venting correctly.

Step 3: Connect Tank to Water Supply

With the discharge pipe in place, you can now proceed to connect the water tank to your water supply.

Doing this ensures that the toilet will be able to remove the waste properly.

Step 4: Plug Pump into GFI Outlet

Once the tank is connected to the water, you should plug in the macerator pump into the GFI outlet.

Note that some models will require batteries, which makes it important to do preparation on the first step and ensure you have the required batteries.

Step 5: Vent Macerator Pump

Finally, the last step is to vent the macerator pump as this ensures that air can actively move through the system with no hindrance.

And as you are finishing up, it is also important to check all the pipes again to make sure that everything is connected properly and securely.


A macerator toilet makes it possible to place a toilet in areas where you never thought possible, and with our top 10 reviews above, it should now be easy to find one.

From these reviews, the Saniflo 081-083-005 is our best overall and top recommendation as it is highly efficient given that it can handle both waste and toilet paper, it operates more quietly and has a more conventional appearance.
