Macerators Made Clear

There may come a time where alterations to your home are necessary or desired, and these alterations may require you to install a new sink, shower, toilet or even an entire bathroom. As you can imagine, there are a lot of logistics at play, some easier to manage than others. One such factor in the addition or conversion of a bathroom or toilet, for example, is the need to facilitate the transfer of waste from sinks, showers and toilets to existing waste pipes. Macerators are the method of choice for this job, and we are going to explain what they do and how they do it.

Macerators are used when the transfer of sink and bathroom waste to existing waste pipes in a home is difficult or infeasible due to the distance or height between the source of the waste and the home’s soil and vent pipe.

What is maceration?

Maceration is the process of changing solids into slurry through soaking them in liquids that are already present. This makes it easier for domestic plumbing systems to transport solid waste.

What is a macerator?

A macerator is a pump that boasts an extra capability of finely chopping solids so that they are in a near-liquid state. The smaller pipes of domestic properties mean that this process is important to efficient pumping – the macerators themselves are used when installing a soil pipe across multiple rooms is to be avoided, for practical, financial and aesthetic reasons. They are often used in bathrooms, kitchens, showers and toilets.


They are usually situated behind or within the toilet, and they’re connected to the main electrical supply. When used in kitchens for sinks, the macerator is hidden in a kitchen unit, but it can be placed behind a removable panel for access purposes, if necessary. When it comes to showers, the macerator will be installed underneath or next to the shower tray.


Regarding the installation of a macerator, you needn’t worry about any building regulations. The only thing you must do is ensure that a qualified electrician installs it and connects it to your mains.


The macerators themselves are pretty much maintenance-free, and where macerating toilets are concerned, there’s little chance of major issues if they are used correctly. That is to say, the same rules of what you can and can’t flush down a toilet also apply to macerating toilets. No wet wipes!

How much does a macerator cost?

The price of macerators often varies between £350 and £600. These are the average figures, but there are more expensive models available, too. When pricing up a macerator, it’s wise to include the cost of the pipe work involved in connecting the macerator to your property’s soil stack – this job should cost between £200 to £250. However, that cost can change based on various factors e.g. if distance between macerator and soil system is excessive.

If you’re looking to add a new bathroom, kitchen or shower to a property, but the location of your homes drainage systems are hindering your work, then a macerator may be what you need to keep your renovation dreams alive.
