Best Macerating Toilet Reviews – Upflush Toilet For 2021

One common remodel project homeowners take on is fixing up their bathrooms. There are a lot of things to think about for a bathroom remodel, including designs, colors, hardware, and piping.

Unfortunately, many would-be bathroom renovators have their plans dashed because their chosen location is too far from the house’s main drain line. This tends to happen in locations that are below the rest of the house’s main drain line, such as basements. Since there is no gravity to draw waste down, there needs to be an alternate method of waste transport.

That is where macerating toilets come in. When a normal toilet is flushed, waste gets transported through a trap into the house’s main drain line. Since the toilet is above the drain line, gravity pulls the contents through. Macerating toilets (also called “up=flush toilets”), in contrast, send waste to a separate unit located behind the toilet or in the wall. High powered blades in the unit liquefy the waste, which is then pumped through an extra pipe fitted to the house’s main drain line. Macerating toilets are more expensive than regular toilets, but they are easier and less expensive than redoing the house’s draining system.

So macerating toilets are one solution to bathroom renovation problems. Today we are going to talk about the best macerating toilets in 2021. These macerating toilets have been chosen based on their quality, ease of installation, and overall cost. Without any further ado, let’s get to it.

Best Macerating Toilets for Your Bathroom Renovation

1. Liberty Pumps Ascent II

Liberty Pumps Ascent II

Up first is the Liberty Pumps Ascent II, one of the most advanced macerating toilets of its kind. The main draw of the Ascent II is the patented RazorCut technology that ensures waste is properly liquefied The maceration unit can be placed up to 150 feet away from the main drain line and can be as far as 25 feet under. It’s perfect for rooms under the house’s main drain like in basements.

The Ascent II is WaterSense certified and uses an impressive 1.28 gallons per flush so it’s very eco-friendly and efficient. The elongated bowl, white finish, and standard tank goes well with any bathroom setup and at only 29” across, it won’t take up too much space. It is a great option if you want to convert a smaller side room into a half bath. The Ascent II is also ADA complaint for seating height so it can be used easily by those with disabilities.

Installation of the Ascent II is easy and can be performed at home with minimal tools. You also don’t have to worry about electrical wiring. The macerator unit runs on 1.9-volt batteries that last about 3 and a half hours. This means you will have to periodically change batteries, but they are easy to replace. Also, a removable service panel gives you direct access to the macerating blades without disconnecting the plumbing, so it’s easy to clean out the unit and replace blades if need be.

What we liked:

  • Space conscious and lightweight
  • Easy to install DIY
  • Powerful RazorCut macerator blades
  • Removable panel gives direct access to blades
  • Water-efficient and eco-friendly

What we didn’t like:

  • Batteries need to be replaced periodically
  • Gets clogged by thicker toilet paper

2. Thetford Marine Nano ECO Macerating Toilet

Thetford Marine Nano ECO Macerating Toilet

This macerating toilet from Thetford is one of the smaller designs out there. The main draw of the Marine Nano is its size and convenience. It is specifically designed for use in recreational vehicles and boats and only needs 12 volts to operate. It can be installed in homes, but you will have to build a small platform to mount it. The ports in the back are all standard size which makes installation easy, no matter the location and the entire bowl is made from vitreous china which is resistant to stains and scratches toilet bowls usually pick up.

The addition of the work “Eco’ in the title isn’t just for show either. The Marine Nanoe has a special ECo switch that lets you change between raw water supply and a pressurized system found in houses. It’s very quiet, has low water usage, and has a fast flushing cycle so the bowl stays clean. The special turbine tech keeps the tank from getting clogged and properly liquifies waste for removal.

As we said, the toilet only requires 12 volts to use so it can be hooked directly up to your RV or boats power supply and not have to worry about it draining your batteries. One problem we did notice is that it is pretty small so larger people might have trouble using it. It is extremely easy to install thought and it can be installed without the need to place seals, gaskets, or accommodate a vacuum pump.

What we liked:

  • Small, compact, and light
  • Low electricity consumption
  • Strong turbine system for breaking up waste
  • Standard openings make installation easy
  • No need to place seals, gaskets, or vacuum pump

What we didn’t like:

  • Too small for some people to comfortably use
  • Relatively low tank capacity

3. Saniflow Sanicompact One Piece Toilet

Saniflow Sanicompact One Piece Toilet

Coming in at third is the Saniflow Sanicompact One Piece toilet, one of the best up flush toilet models on the market. As the name implies, the entire toilet/macerating unit is one piece which makes it super easy to move and install. Since the tank is inside the unit, it is easy to situate it flush to the wall and is very presentable.

The Saniflow can be positioned up to 100 feet horizontal to the main drain like and 9 feet below. This means you have a lot of leeway in where you place it. The slim vertical design is compact and great for smaller rooms with lower ceilings.t is also very eco-conscious/water-friendly and only consumes about 1 gallon per flush. The stylish toilet seat with chrome hinges looks great and is tall enough to fit most people comfortably.

One other feature we like is the single-push button flush mechanisms with a non-return valve. This ensures that wastewater doesn’t seep back into the bowl after each flush. This feature minimizes water usage and keeps the toilet bowl clean between use. Installation is pretty straightforward too. Just position the toilet where you want and feed the drainage pipe through the wall into the house’s main drainage system,.The discharge pipe itself can be rotated 360-degrees so it can fit any type of installation requirement.

What we liked:

  • Compact and easy to place flush to the wall
  • Macerator and water pump on an electric auto timer
  • Return valve blocks wastewater from seeping back into the bowl
  • Discharge pipe rotate 3260 degrees
  • Chrome-plated hinges and push-button are durable
  • Macerator can be connected to a ground fault interrupter circuit

What we didn’t like:

  • Install is custom, so it may cost a bit if you have it professionally installed
  • Pump runs louder than average
  • Toilet needs to be regularly “cycled” or else it develops odors

4. Saniflow Sanibest Pro

Saniflow Sanibest Pro

The Saniflow Sanibest is considered one of the best heavy-duty up flush toilets and with good reason. The Sanibest has a heavy-duty macerating system, low pressure requirements, and has a number of user-friendly features like the water consumption rate and ease of installation. The Sanibest uses a powerful 3600 RPM steel blade system to liquefy waste which runs very quietly compared to some other macerating toilets.

The installation consists of 4 total connections and the toilet can work up to 18 feet below the sewer line and up to 100 feet horizontal to the line. As a nice added feature, the discharge pipe can also connect to your washing machine or a sink. The kit itself comes with a bathroom pump, standard bowl, and toilet tank. The UPC on each toilet tank ensures you have the best possible compatible components for your bathroom.

The real driving point of the San8iflow is the powerful blade system. The blades are made out of stainless steel and operate at 3600 RPM, quick enough to liquefy even the toughest waste. A common spindle turns both the macerator blades and impeller, which minimizes the total amount of moving parts. The Saniflow is also very water-conscious and only consumes 1.6 gallons per flush so you will save money on your water bill compared to a traditional toilet.

What we liked:

  • Heavy duty
  • Powerful 3600 RP stainless steel blades
  • Minimal moving parts
  • 4 different connector ports
  • Discharge pump can connect to washing machine and sink

What we didn’t like:

  • Runs loud
  • Doesn’t handle thick toilet paper well

5. Lift Assure American Round Macerating Toilet

Lift Assure American Round Macerating Toilet

Coming in at fifth is the Lift Assure American Round Macerating Toilet. The first thing to notice about this toilet is its classic design. The Lift Assure has a high back tank design that looks like a standard toilet found in a full-size bathroom. Despite the elongated design and back tank, the Lift Assure is very space-conscious and is easy to situate flush against the wall. It is also a good height so it can be used by people of all sizes.

The Lift Assure has a 3-port input water processing mechanism that instantly processes water as soon as it hits the mechanism. The entire toilet runs on 120 volts and can be plugged into any standard outlet. The dowl has a depth of 24” and is 15” wide so it’s about the size of a standard toilet. The Lift Assure uses more than 3.8 gallons per minute, so it does use more water than some other macerating toilets bu this helps it break down waste quickly and force it through the pipes better. As such, you should never have to flush twice to get rid of all waste and prevent water backflow.

The Lift Assure is a sold choice but its not perfect. First of all, it runs pretty loud at about the level of a dishwasher, not incredibly bad but it can still get annoying if you use it a lot. Also, since it is taller than a lot of other toilets and has a full tank on the back, it may be harder to situate flush against the wall. However, it is very easy to install and the fact that you can just plug it into a standard 12- volt outlet is a great touch that makes it easy to set up.

What we liked:

  • Big, full-size design
  • High water capacity clears waste and prevents wastewater backflow
  • Works in RVs as well as homes
  • Works with any 120-volt outlet
  • Strong materials and durable construction

What we didn’t like:

  • A bit tall and hard to situate
  • Push-button instead of handle for flushing is somewhat touchy
  • You can’t use it if you don’t have a nearby outlet

6. Liberty Macerating ½ HP Macerating Toilet

Liberty Macerating ½ HP Macerating Toilet

Liberty is a well-known name among the macerating toilet industry and for good reason. The ½ HP macerating toilet is their flagship model and has some great features that increase its overall utility. First things first, the Liberty comes with its own toilet seat. That might sound like a no-brainer but a lot of these macerating toilets don’t come with their own lids so you have to buy one separately. It is a bit on the heavier side at 112 pounds, but once you install it will work so good you’ll never want to move it again.

The round bowl and high back tank echo the style of a full-size standard toilet that is high enough for people of all sizes to use comfortably. It is made from strong materials and the macerator unit runs very quietly, about as loud as a small dishwasher. It can also be set up to handle water form a shower and utility sink so you could set up an entire bathroom with just the plumbing from this unit.

The model also comes with a dual flush function that lets you pick either a half flush for liquid waste and a full flush for solid waste. The dual-flush mechanism ultimately ends up saving you money on your water consumption. In that sense, it’s a great option for eco-conscious shoppers. Lastly, the classic white color will fit any bathroom and any color scheme.

Overall, the Liberty is a great macerating toilet that is a bit more heavy-duty than some other ones out there. One problem we did notice is that the backflow valve sometimes doesn’t work right and lets water back into the bowl. Unfortunately, this does mean you may have to flush twice for large quantities of waste.

What we liked:

  • Solid, durable construction
  • Comes with a toilet seat
  • Dual-flush function save water in the long run
  • Classic white color goes well with any decoration scheme
  • Cand also run drain from shower and utility sink

What we didn’t like:

  • Heavy and hard to move
  • The back tank is large so it can be hard to situate it flush to the wall
  • Backflow valve does not work all the time

7. Saniflow Saniplus

Saniflow Saniplus

Up next is another from Sanifllow. The Saniplus is a heavy-duty solution for heavy-duty waste and gives you a way to install a macerating toilet without having to drill or break into the floor. The Saniplus can be placed anywhere up to 15 feet below the sewer line and up to 150 feet horizontal to the main drain line. The Saniplus pump can be connected to any sink, shower, or bathtub so you can convert an entire room into a full-sized bathroom with just this kit.

The Saniplus is a heavy-duty unit and it uses 1.6 gallons per flush. Even though it is heavy-duty, it runs very quietly and has been compared to the sound of a microwave. Installation is straightforward as you can connect it without having to cut any holes in the floor or walls. Just place the toilet, connect the pipes, and you are good to go. Like the Sanibest, a common spindle runs the macerator and impeller which minimizes the number of moving parts and makes it less prone to breaking or clogging.

We should mention that, compared to some other macerating toilets, the Saniplus is pretty expensive but completely worth the purchase if you have the money. Also, the manufacturer offers a generous 2-year warranty for repairs or replacement parts.

A few things though; You can’t clean out the Saniplus with just any cleaning solution. It requires its own specific cleaning solution and any other kind can damage the components. This is a bit annoying as you have to buy the cleaner separately, but it does a much better job cleaning the internal components than a general cleaning solution would. We also noticed that its a bit tough to attach the accordion connector through the wall extension tube, but that isn’t anything you can’t fix with a little effort.

Otherwise, the Saniplus is a solid choice. It is a bit on the pricier side, but you are really paying for good quality construction so it’s worth it

What we liked:

  • Connects to sink, shower, bathtub, or bidet
  • Minimal moving parts means it is less prone to clogging and breaking
  • Runs very quietly
  • Great quality construction

What we didn’t like:

  • Expensive
  • A bit tough to connect the pipes to your drainage system
  • Heavy

8. Bathroom Anywhere Macerating Elongated Toilet Bowl

Bathroom Anywhere Macerating Elongated Toilet Bowl

Up next is this compact macerating toilet form Bathroom Anywhere. Like the Marine Nano covered earlier, the Bathroom Anywhere has a small profile, low height, and is designed to work with RVs and boats. This model comes with the macerating pump fully integrated into the main unit so its all one piece and can be transported together. This also means you don’t have to have any specialized systems to handle the toilet. Even better, the product comes with a user manual that tells you exactly how to install it on your own, no professional help needed.

The Bathroom Anwyerhe also has a strong water flow that uses up to 1.28 gallons per flush. This makes it very water-conscious and ensures waste is cleared away and doesn’t come back through the backflow valve. The contemporary style bowl is elegant and comfortable, but it may not be the right height for everyone. Specifically, it is not ADA compliant for those with disabilities and taller users may have trouble getting comfortable.

One of the better features of the Bathroom Anywhere is how easy it is to clean. Since it’s all integrated into a one-piece design, you can clean the bowl and macerator unit at the same time with the same toilet bowl cleaner. The strong pump action also means that waste won’t sit in the bowl and fester.

The main thing we like about the Bathroom Anywhere is how simple it is to set up.

What we liked:

  • Small and compact
  • Lack of the back tank means it’s easy to place in tight spaces
  • 80 HP 120 volt macerator unit is very strong
  • 1.26 gallons per flush
  • User manual gives explicit installation instructions

What we didn’t like:

  • Small and may be hard for larger people to use
  • Can get clogged with thick toilet paper
  • Tank unit is sold separately, it would be nice if it were included
