Saniflo Macerating Toilet Review

The Saniflo Macerating Toilet is quite different to most standard toilets in that it uses macerating and a pump to remove waste, rather than flushing directly into the drainage system. This makes the Sanicompact 48 an ideal solution to fitting a toilet in areas where a standard flush toilet is impractical.

A waste pipe from a sink can also be hooked up to the toilet making it an ideal solution to building a half bath in places where a standard toilet would be impractical. The pump on the toilet can pump up to 9 feet in height and 100 feet horizontally, all through a 1” pipe. Let’s read Saniflo Macerating Toilet Review in detail.

Design / Materials

This small toilet is only just over 18” high and protrudes from the wall by 20”. It looks like a standard toilet apart from the fact that it has no cistern.

It features your classic porcelain design, which is a standard material for toilets. It’s durable, strong, easy to clean, and it always looks nice too.

Of course, the seat and seat cover are made of plastic, but they do feature chrome hinges to ensure smooth operation and long-lasting durability.

This toilet is actually quite special as it is designed very small. It’s ideal for small spaces where a full toilet just cannot fit.

It does not have a water tank on the rear, which means that it is very compact and short, thus being able to fit in places where normal sized toilets can’t go.

It’s definitely a convenient option to go with if you have a really tight space where you would like to build a bathroom. What is pretty cool here is that you can also attach a sink to this toilet and use the same water supply for both, a big innovation no doubt.

Flushing System

As mentioned above, the Sanicompact 48 does not use a conventional flushing system. Instead, once the flush button is pressed, the toilet fills itself with a set volume of water, then this, together with the waste, is drawn through macerating blades and pumped out through the 1” waste pipe.

The flushing system is explained in this video from Saniflo.


As you can see from the video, the Saniflo sanicompact 48 uses a special gravity flush system to flush, which is pretty cool. Of course, this means that you do not need to have a water tank on the rear of it.

This toilet uses a macerator and pump to flush. This means that water rises into the toilet from below, thus filling the bowl and cleaning the sides. There is then a mechanism, the macerator, which macerates the waste, and a pump which pulls everything back down.

It’s actually quite a simple flushing mechanism, but it works very well indeed. There is a timer which then automatically refills the bowl for the next use.

This is a great alternative to your classic flushing system, as it used much less water and takes up less space.

Something you should be aware of though, is that it is quite loud. It does make some noise when pumping and macerating.



This toilet, due to its method of operation has a high efficiency cleaning system for removing waste. In areas with hard water, it is advised to clean the toilet with a decalcifier once a year to prevent valves sticking open.

The macerating blades and impellor benefit from additional cleaning if the waste from a sink is attached as the waste water from this is pumped through the same system.



There are two flushing options both operated by a button, a 1 gallon and a 1.28 gallons flush.

The system operates on a timer rather than measuring the amount of water used, so the values for water consumed are approximate.


Ease of Installation

This is a little more complex to install than a standard flush toilet. If it is a new installation, rather than a replacement macerating toilet, there is a likelihood that you will need to run a 1” pipe from the toilet to the waste pipe, which can be a little involved depending on the route that the pipe has to follow.

That being said, the installation of the toilet, even including the option to use the toilet to get rid of waste water from a sink, is quite straightforward.

An electrical outlet is needed nearby to provide power to the pump and macerator. Saniflo installation instructions explain all the steps.  The electrical outlet used to power the toilet should be connected to a ground to reduce the risk of electric shock.

Saniflo recommend using a plumbing professional for installation.



  • Can be used in locations where a standard flush toilet is impractical – such as in a basement
  • Small compact size which is ideally suited to smaller spaces
  • Low water consumption per flush
  • 2-year warranty



  • Installation is more complex than with a standard flush toilet


Overall                           4.4/5

The Saniflo SANICOMPACT  should not be compared to a standard toilet.

A macerating toilet is designed for a specific set of circumstances where the use of a standard toilet is either impractical or too costly, due to the needs of a gravity fed waste pipe.

This toilet is an excellent option where space is a little tight or distance from the main waste pipe is a problem.
