Best Macerating Toilet in 2024

Looking for the best macerating toilet in 2024?

Macerating toilets, also known as upflush toilets or grinder toilets, are innovative plumbing fixtures that offer unique advantages over traditional toilets.

Unlike gravity-flow toilets that rely on large drain pipes and a direct connection to the main sewage line, macerating toilets utilize a built-in electric pump or grinder mechanism to pulverize solid waste and toilet paper into a fine slurry.

This slurry is then efficiently pumped through smaller-diameter pipes, allowing for versatile installation in various locations, including basements, garages, or areas below the main sewer line.

Macerating toilet short buyer’s guide

What aspects should you consider when choosing a macerating toilet system? Do you need to know how to install a macerating toilet system? Before choosing a product, keep top of mind the following considerations:

  • Design

Many customers care a lot about the way the toilet integrates into the bathroom’s design. Macerating toilets are available both in the round and elongated version. Some homeowners prefer the elongated version as it provides a more modern look and increased comfort.

  • Easy installation

If you want to install the toilet yourself, choose one that has clear instructions. Otherwise, you may need help from a plumber.

  • Gallons per flush

Even if you want to reduce water consumption, check toilet performance first. The current standard is 1.6 gallons per flush. Aiming lower than that could cause waste to remain stuck to the toilet bowl.

  • Extra features

Some users may want nice-to-have options such as bidets, heated seats, etc.

  • Warranty

Pick a toilet with a warranty of 2 years the minimum. If your toilet malfunctions, you will want to have it repaired or replaced free of charge.

  • Quality

The macerating blade should be made from stainless steel and be powered by a strong engine. Otherwise, you may deal with clogs very frequently.

  • Included parts

Many customers prefer macerating toilet kits that contain toilet bowl, tank, pump, and macerating unit. Kits are more cost-effective and you don’t have the trouble of finding matching tanks or toilet seats.

  • The number of decibels

A modern macerating toilet should be powerful enough to evacuate waste without making a very loud noise. However, a certain level of noise cannot be avoided. You will need to weigh balance with silence and make a decision.

Reasons to install a macerating toilet system

Even if a macerating toilet is not recommended as a primary toilet, there are plenty of good reasons to install one:

  • Avoiding expensive and complex plumbing work

Macerating toilets are more expensive than standard toilets. However, they are preferrable to building an entire plumbing system to install a toilet in a hard-to-reach area. This option can be even more expensive.

  • Less damage to your property

You want to install a toilet by the pool and the plumber gave you some bad news? Truth is nobody wants to break through the floor or drill through concrete. Installing a drain line for conventional plumbing is not just expensive, but also messy.

Forget about digging and re-cementing. You can create a reliable bathroom anywhere by installing a macerating toilet, with little to no damage.

  • Installing a toilet in unusual locations

Macerating toilets can bring you comfort and convenience in off-the-grid cabins, basements, and workshops. They can be installed in areas located lower than your drain line due to the pump that pushes liquefied waste upwards.

  • Fast and easy installation

Installing a macerating toilet can be a DIY project that will be ready in just a few hours. You may not even need a plumber to help. All things considered, this option is faster and cheaper than installing a typical toilet system.

How to install a macerating toilet system

Wondering how to install a macerating toilet system? The first step is getting prepared.

  • Preparation

Before starting your macerating toilet project, make sure you have a venting source and an easily accessible water supply. Also prepare a discharge pipe between ¾ and 1 inch and an electricity source with GFI breaker.

  • Connecting the discharge pipe

Use a discharging pipe of appropriate size. Avoid 90-degree turns. Make sure the discharge pipe is properly vented.

  • Connecting to the water system

Connect the toilet tank to the water supply so you can flush water.

  • Connecting the toilet to the power supply

The toilet pump needs to be plugged into a GFI outlet. Use a 15-amp electrical cord.

  • Ensuring pump vent

The macerator pump needs to be vent into the home’s vent system. This enables air from the pump area to move in and out. It is also possible to build a new dedicated venting system; just make sure it complies with codes.

Cons of macerating toilets

Even though this type of toilet can be an excellent option, it does not come without some drawbacks:

  • Depending on electricity

You will not be able to use the macerating toilet during power outages.

  • Making noise

The noise of the pump is noticeable, even if manufacturers make efforts to design quiet devices.

  • Prone to clogs

Accidentally flushing items that you are not supposed to flush can cause a clog. Providing access for servicing is vital.

  • Pump needs to be kept primed

This means you need to flush the toilet at least once a day. Not using the toilet for a while comes with the necessity to deactivate the pump. [2]
