Upflush toilets are a way better option than your ordinary, standard toilet, mainly because of the fact that upflush toilets perform better than standard toilets, they are fairly movable, space-efficient and require less time in terms of installation and use less water without sacrificing the performance! We’ve done a lot of toilet reviews before, but we’ve never talked about macerating toilets.

Even though they aren’t new in the market, throughout the years, they have become popular again which says a lot about their quality, and my primary purpose is to keep in touch with the latest trends so that my audience would always be informed with updated information regarding a variety of different products.

However, choosing the ideal macerating toilet for your needs can often be problematic, due to the fact that there isn’t only one macerating toilet, instead, there are hundreds of them available on the market, so you would need to read a lot before you choose the one that may be considered as the best. If you want to find out more about different models and types, you can check out our general toilet buying guide

Don’t worry though, I’ve already done this job for you, all you would have to do would be to read the article and choose the upflush toilet which you find the most visually pleasing, the macerating toilet which performs pretty good, or the upflush toilet which combines both of these attributes? Each of the included upflush toilet is carefully chosen, so you can’t go wrong!

Now, let’s get started so that you can have an idea of what I’m talking about!

The Top 5 Best Upflush Toilets

5. Liberty Pumps ASCENTII-ESW

Our Ratings:



The Liberty Pumps ASCENTII-ESW has been around the market for a fairly long time, but what’s interesting is that since its release date, it has become widely recognized by the users on the market because of its ability to deliver a reliable and highly effective performance, so if you’ve been looking for something similar, then let’s see what can you expect from this one!

Design-wise, the ASCENTII-ESW has an attractive, all-white, space-saving construction that measures 29.8 x 20 x 32.2-inches, weighs approximately 110 pounds and if you take a look at its dimensions, you already know that regardless if your bathroom is small, medium or large, you won’t have difficulties placing this macerating toilet in your bathroom.

In addition, this unit employs a reversible, 4-sided enamel tank which I particularly like because you will be able to choose whether the supply should be set on the left or right, and what’s even better is that this can be done without even dismounting the float valve!

Moving on, installing the ASCENTII-ESW is a very easy process, due to the fact that this model comes with pre-assembled/pre-installed nuts, fixing screws and a toilet seat, but what also got my attention is that thanks to its design, this unit is compatible with additional shower/tub/sink connections as well!

So, you will have two options, whether you take advantage of the installation guide that is included in the package, or the second option which is hiring a plumber. I’d recommend you keep in mind that if you’ve never installed an upflush toilet or lack technical knowledge, it would be better if you hire a professional because you will avoid undesirable situations.

When it comes to the performance, I would like to inform you that the ASCENTII-ESW is a highly-efficient toilet, because its water consumption is rate at 1.28-gallons per flush, and when we add the fact that it is WaterSense-certified as well, it means that your water bills won’t be salty at all!

Furthermore, this upflush toilet uses a so-called RazorCut technology which consists of stainless steel blades that offer powerful yet quiet cutting, but let’s not also forget the Advance Run Technology whose purpose is to activate the blades before debris starts entering the cutter basket.

Last but not least,  the ASCENTII-ESW comes with other features as well, including a built-in alarm along with 9-Volt battery that can serve you as a backup, and since I’ve mentioned the battery, I would like to inform you that its battery life is rated at 3.5 hours according to the manufacturer.

To summarize, Liberty Pumps have done a really good job in manufacturing a quality, upflush toilet such as the ASCENTII-ESW, and if you ever decide to purchase it, I think that you will never regret that decision!

4. Saniflo Sanibest Pro

Our Ratings:



The Saniflo Sanibest Pro is yet another popular upflush toilet that has established itself as a truly reliable option from the moment it has appeared on the market, and the reason behind its success is the durability and its fast-paced blades that are known for distributing an amazing performance!

From a design perspective, this unit features an attractive, all-white construction that consists of a coated plastic toilet seat and lid as well as of a porcelain macerator chamber, while at the inside, or better said the interior, there are components made of plastic, metal and rubber which help the pump to power along with its grinder and macerator! As you can see, these materials make this unit exceptionally durable, so you won’t have to invest in another one for a really long time!

When it comes to the installation, well, the Sanibest Pro requires a professional because there are some parts and connections that should be installed properly, however, if you possess technical knowledge of toilets and plumbing you may do everything by yourself.

Either way, I do recommend getting a professional instead since they know more than a typical user.

Moreover, the performance is the biggest highlight regarding the Sanibest Pro upflush toilet. Namely, this model incorporates exceptionally quick, macerator blades that deliver 3600-rotations per minute, and after they turn solid waste into small particles, then this macerating toilet pumps the effluent up to 25 feet upwards/150 feet horizontally thanks to the gravity fall.

According to some users, this model can be loud at times but not that loud to wake your entire family in the middle of the night, so I think that you can handle its performance.

But, what’s also interesting is that the motor is very durable and the reason behind this is the fact that it is permanently sealed in an oil-filled enclosure. So, after years of use, you will unlikely notice a decrease with the performance!

I would also like to mention that the Sanibest Pro spends only 1.6-gallons per flush which is pretty cool due to the fact that the water consumption is very low and this by default means that your water bills will not be heavily affected!

Overall, if you’re looking for an upflush toilet that combines quality performance with a higher level of durability, then the Sanibest Pro would be an ideal option for you!

3. Saniflo 023

Our Ratings:



The Saniflo 023 is currently among the most widely-known and most purchased macerator toilets and you’ve probably seen this name multiple times on the Internet which is a great proof that speaks a lot regarding the quality of this toilet! Well, today you will find out what’s so special about it so let’s get straight into the action!

Aesthetically speaking, the Saniflo 023 measures 18.25 x 14.5 x 15.75-inches, weighs around 62.2 pounds and boasts a compact and modern, all-white construction that is made of polypropylene, carbon fiber reinforced polymer (CRP), stainless steel and neoprene material which is awesome if you ask me, because these materials will contribute a lot in maintaining the unit’s life expectancy as much as possible! In addition, if we take a closer look at its dimensions, without a doubt I can say that this macerating toilet will not take a chunk of space of your bathroom. This is especially important if you have a small bathroom where space is scarce!

Moving on, the Saniflo 023 can be installed virtually anywhere aside from being placed in your bathroom, you can even install it in your basement, ground floor/upper floor and even in a garage! As a matter of fact, its installation should not be problematic at all since this unit comes with an installation sheet, so if you have experience in installing macerator toilets you may do it all by yourself. It’s pretty easy to install and self-explanatory.

Performance-wise, this macerating toilet uses only 1.3-gallons of water per flush which is pretty cool because this is an attribute of a really water-efficient product, but what’s also great is the motor that offers up to 3600-rotations per minute, and the toilet’s ability to offer vertical pumping up to 9-feet or 100-feet horizontally.

According to those who have already purchased this product, the Saniflo 023 is fairly comfortable, performs pretty well and they really liked the fact that the macerating pump cycle is automatic. Some of them were especially satisfied by the toilet’s ability to rotate up to 360-degrees for installation, so without a doubt, I can say that the manufacturer has done a really good job here!

I would also like to mention that this macerating toilet has a running time that stretches from 10-15 seconds, but thanks to its motor, the waste during this time will be properly eliminated and afterward, the elongated bowl will be refilled with fresh water again!

Before we end, there is yet another thing that should be said, and that’s regarding the cleaning. It is advisable if you clean your toilet with a decalcifier at least once a year so that you can prevent the valves from getting stuck, while on the other side, this would come handy for the macerating blades as well!

The thing I like the most about this toilet is its elongated bowl. An elongated bowl is very important because its way more comfortable for adults. If you’ve never tried a toilet with an elongated bowl before, you will love them!

In conclusion, after all you’ve read, I think that you already know the benefits that this macerating toilet brings in a case of an eventual purchase, so, I’d recommend you consider it seriously and if you ever decide to purchase it, you will assure yourself of its capabilities!

First of all, this model is quiet, and most of the users claim that they were never bothered by the noise like is the case with most of the macerating systems on the market.

1. Saniflo SaniPLUS

Our Ratings:



We’ve done a lot of toilet reviews before, but the Saniflo SaniPLUS is so far, one of the best macerating toilets that you can find on the market. After I’ve read hundreds of positive toilet reviews from the users, I’ve decided to list this unit as a #1 choice for everyone who is keen on investing in a highly reliable and quality toilet! Ready? Let’s get straight into the action so that you would have a better understanding of the things that make this unit be considered as a top choice!

In terms of the design, this particular model measures  16-3/4-inches in height ( seat), 26-1/2-inches in depth (overall), weighs approximately 99.7 pounds and sports a minimalist, white-colored design which will grab your attention from the moment you take it out of its box!

Thanks to its well-made design,  you won’t face problems during the installation. Namely, this unit lets you process greywater from virtually any sink, shower or bath, and within a few hours, you can do everything by yourself, so, no more plumbers and additional costs!

To be more precise, this system can be installed up to 15 feet below the sewer line or up to 150 feet away from the solid stack, and what’s even better is that you will be given an installation manual which is really easy to follow.

According to the manufacturer, you should note that there are 4 connections for this toilet, so, as you can see, it is actually very simple.

The first thing you should know is that the macerating/pump should be connected to the spigot of a horizontal outlet toilet, the second thing is the toilet tank which is connected to the water supply, while the third is that you should pay attention on the macerating/pump which is connected to the small diameter discharge pipework. Finnaly, the macerating/pump should be connected to an electrical supply! This is fairly easy since you won’t have to make a mess in your bathroom in order to install this unit properly.

Moving on, the performance is the key reason when you look at macerating toilets, so let’s see what does this one has to offer.

The Saniflo SaniPLUS has powerful, macerator blades that rotate at 3600 RPM, while the pump itself operates at 10 PSI, so, when you activate the flush, instantly the water starts flowing into the toilet and as it goes, it instantly activates a microswitch that is positioned in the pressure chamber and this activates the motor. Once it is turned on, the human waste and organic wastes are transformed into a slurry quickly and effectively, and are then picked up by the impeller pump that is strategically positioned beneath the motor.

Some of the users claim that this upflush toilet may be noisy during the process, however, it is not that loud that can cause you discomfort. This is fairly normal with most of the upflush toilets though.

Lastly, this model has a normal operating cycle that stretches from 10-15 seconds which is really good due to the fact that it keeps power consumption to the minimum, and when we add the fact that the SaniPLUS has been tested in over 30,000 cycles, without a doubt I can say that this is an absolute monster in terms of durability!

Overall, the Saniflo SaniPLUS may not be the cheapest upflush toilet that you can get on the market, but considering its tremendously good performance, durability and design, I think that it justifies its price tag and you should definitely consider it as a must-have product!

How Does A Macerating Toilet Work?

An upflush toiletToilets in general,  perform mostly the same because all of them would flush when you press the lever, all of them require maintenance and all of them can enhance the beauty of your bathroom.

However, what makes them different from the standard toilets is that they preserve a lot of space when compared with standard toilets and do not require to be placed in a specific area of your bathroom due to the fact that they are indeed space-efficient.

In practice, upflush systems discharge out the back through their macerator and pump tank. To simplify this, when you flush the toilet, the macerator comes into action and uses a fast-cutting blade which transforms the waste into a fine slurry that is distributed easily through a narrow pipe upward. These toilets were also called grinder toilets and were especially popular during the late 1950’s mainly in Europe.

Advantages and Disadvantages Of Upflush Toilets

Like every product, those toilets have advantages and disadvantages so let’s name their good and bad sides.

The advantages include:

  • Less Installation Time: Upflush toilets are fairly simple when it comes to the installation because they require minimum digging and breaking so you won’t find yourself in a mess during the installation. Unlike other complex toilets, those are very easy to install
  • Portable: These toilets are highly portable, hence, if your current situation changes in terms of selling your house or if you want to move to another apartment in another city, you can easily take the upflush toilet with you. As a matter of fact, they leave only 4 tiny holes as a footprint of their existence which is awesome!
  • Eco-Friendly & Water-Efficient: If you ever decide to purchase an upflush toilet, be sure that you’re doing a great job in saving our planet. To be more precise, these types of toilets use minimal water to flush and this comes handy especially in terms of reducing the amount of water that each household is wasting. On one side, you won’t affect the planet negatively, while on the other, those toilets will ensure that your water bills will not be affected. Great deal, right?

The disadvantages consist of:

  • Noisy: They can often be noisy because they employ a separate pump and a macerating system. However, it won’t take long until you get used to them and this shouldn’t be a huge problem.

Things To Know Before You Purchase an Upflush Toilet

  • Gallons per Flush: Keep in mind that fewer gallons per flush, mean more water preserved. In general, 1.6-gallons per flush is optimal, so I’d advise you take a look at toilets with this rate.
  • Macerating Pump: I’d recommend you pay attention to the material that macerator blades are made of. Stainless steel is one of the most durable materials in the world, so, try getting stainless steel macerator blades.
  • Styles: This type of toilets come in two different versions such as One-piece and Two-piece. The one-piece version is the most preferred version because they require less cleaning and maintenance. On the other hand, two-piece upflush toilets offer you a benefit in terms of replacing the tank/bowl all by yourself, so that you won’t have to hire a plumber. However, they aren’t as beautiful as one-piece toilets.
