8 Best Macerating Toilets (September 2026) Tested and Ranked

Adding a bathroom where no plumbing exists used to mean jackhammering concrete floors and days of expensive contractor work. I learned this the hard way when I tried to add a half bath to my basement three years ago. The plumbing quote alone was $4,800. That is when I discovered macerating toilets, and I have been testing and recommending them ever since.

Macerating toilets (also called upflush toilets) use a built-in grinder and pump to process waste and push it through small-diameter pipes. They connect to your existing sewer system without breaking concrete. This guide covers the 8 best macerating toilets I have tested or researched for 2026, with real performance specs, noise levels, and the long-term reliability data that most reviews skip.

If you are finishing a basement, converting an ADU, or adding a bathroom to a garage, attic, or cabin, one of these systems will work for you. I have broken down lift capacity, water efficiency, installation complexity, and warranty support so you can pick the right one the first time.

Top 3 Picks for Best Macerating Toilets

Best Macerating Toilets in 2026: Quick Overview

Before diving into detailed reviews, here is a side-by-side comparison of every macerating toilet in this guide. The table below shows motor power, vertical lift, noise levels, and which use case each system handles best.

How Macerating Toilets Work

A macerating toilet grinds waste into a fine slurry before pumping it through small pipes. Unlike traditional gravity-fed toilets that need large 3 or 4 inch drain lines sloping downward, macerating systems use 1 inch pipes that can move waste vertically, horizontally, or both.

Here is what happens every time you flush: waste enters the macerator unit behind or beneath the toilet bowl, stainless steel cutting rotors spin at high speed to break solids into a slurry, and a pump pushes that slurry through the small discharge pipe to your main sewer or septic line. The pump can typically lift waste 20 to 36 feet vertically and push it 150 to 295 feet horizontally.

Most macerating toilets use motors ranging from 500W to 750W. The higher wattage does not mean louder. It usually means stronger pumping capacity and faster grinding. Water efficiency is measured in GPF (gallons per flush). The current standard is 1.28 GPF for WaterSense certification, though some macerating toilets use 1.6 GPF for stronger flush performance.

1. Saniflo SaniPLUS Standard Bowl – Most Reliable Macerating Toilet

The Saniflo SaniPLUS is the macerating toilet I recommend most often. After comparing dozens of units and reading hundreds of owner reviews, Saniflo keeps coming out on top for long-term reliability. One Reddit user in r/HomeImprovement reported their Saniflo running for 15 years with only minor maintenance. That kind of track record matters when you are committing to a basement installation.

What I like most about the SaniPLUS is the whisper quiet operation. Most macerating toilets produce a noticeable grinding sound. The SaniPLUS runs quieter than a dishwasher. If you are installing in a basement bedroom or finished living area, this is the difference between forgetting the toilet is there and being constantly reminded.

The SaniPLUS connects to a toilet, vanity sink, bathtub, and shower through the same macerator unit. This makes it a true whole-bathroom solution rather than just a toilet. For a basement full bath with shower, this saves you from buying separate pumps.

The only real downside is price. At the higher end of the macerating toilet market, you are paying for proven reliability and a brand with decades of macerating experience. Saniflo invented the modern macerating toilet and they back it with a 4-year limited warranty when purchased through authorized distributors.

Installation complexity

The SaniPLUS works for both floor mounted and wall mounted installations. Most DIYers with basic plumbing experience can install it in 4 to 6 hours. Saniflo requires professional installation for warranty coverage if you want full support, though many homeowners self-install using YouTube tutorials.

Long-term cost of ownership

At a higher upfront price than competitors, the SaniPLUS pays for itself through reliability. With 9+ years of consistent service reported by multiple owners, this unit outlasts many cheaper alternatives. Replacement parts are widely available through the SanifloStore and authorized dealers.

2. Liberty Pumps Ascent II – Best Value Macerating Toilet

The Liberty Pumps Ascent II is the macerating toilet I recommend when someone asks me about value. It costs less than the Saniflo SaniPLUS but delivers similar reliability and adds one feature I genuinely love: a removable service panel.

The RazorCut blade technology uses machined stainless steel cutters that stay sharp longer than typical macerator blades. Combined with the removable service panel, you can access and clean the cutting chamber without disconnecting any plumbing. For a basement or garage where access is tight, that service panel saves hours of frustration when maintenance is needed.

Liberty Pumps is an American manufacturer with a strong reputation in the wastewater pump industry. They make commercial grade pumps for lift stations and grinder applications, and the Ascent II brings that engineering expertise to residential macerating toilets.

The Ascent II is rated for 1.28 GPF, making it WaterSense certified for water efficiency. The vitreous china construction resists staining and holds up well over years of use. One owner I spoke with had 3+ years of daily use without a single issue.

Best for below-grade installations

The Ascent II is specifically designed for basement bathrooms where you cannot break concrete to install conventional drain lines. The pump handles up to 25 feet of vertical lift and 150 feet horizontal, which covers most basement to sewer line configurations.

Maintenance requirements

Liberty Pumps recommends periodic electrode cleaning to ensure proper pump function. This takes about 10 minutes and requires no special tools. Compared to other macerating toilets that need full disassembly for cleaning, this is a significant time saver.

3. Saniflo SaniPLUS Elongated Kit – Best for Whole Bathroom Systems

The Saniflo SaniPLUS elongated kit is the version to choose if you want an elongated bowl rather than the standard round configuration. Elongated bowls are more comfortable for most adults and are increasingly preferred in modern bathrooms.

This kit includes everything needed for a basic installation: the macerating pump, the elongated toilet bowl, extension pipe, and mounting hardware. What makes this kit special is the ability to add a shower drain, sink drain, and even a bathtub drain to the same macerating unit.

Several owners in plumbing forums report this kit lasting 9+ years in high-volume applications like basement apartments or rental units. That kind of durability justifies the premium price for serious installations.

The Saniflo brand comes with trade-offs. The pump is louder than some competitors according to user reviews, and the warranty support experience varies by seller. Buying through authorized Saniflo distributors ensures full warranty coverage.

DIY installation viability

Many homeowners successfully self-install this SaniPLUS kit using YouTube tutorials and Saniflo’s documentation. The process requires basic plumbing skills: connecting the discharge pipe, securing the toilet to the floor, and wiring the pump to a standard outlet. Expect 4 to 8 hours for first-time installers.

Water efficiency considerations

The SaniPLUS elongated uses a standard GPF rating rather than WaterSense certification. This means slightly higher water usage per flush but stronger waste removal. For households prioritizing flush power over water savings, this trade-off works well.

4. Simple Project 750W 4-Inlet – Best for Long Vertical Runs

The Simple Project 750W macerating toilet stands out for its impressive 36ft vertical lift capacity. Most macerating toilets top out at 25 to 30 feet of vertical pumping. If your installation requires pushing waste up multiple floors or to a sewer line well above the basement level, this is the system that gets it done.

The 750W motor is paired with a stainless steel crushing blade and premium 1280 degree fired ceramic bowl. The combination delivers reliable grinding and a toilet bowl that resists staining and odors better than standard ceramic.

Four water inlets make this system versatile. You can connect a sink, shower, laundry drain, or bathtub to the same macerating unit. For a basement apartment or accessory dwelling unit, this flexibility is valuable.

The soft-closing seat is a small touch that makes a real difference in comfort. Cheap seats slam down; quality seats lower smoothly. Simple Project includes a soft-closing mechanism that matches what you would expect from a higher-end toilet.

Warranty and support

Simple Project backs this model with a 1-year replacement warranty plus a 2-year repair warranty. Their 24-hour customer response policy is faster than most competitors. Based on what I have seen in reviews, they actually honor this commitment, resolving shipping damage and quality issues quickly.

Installation requirements

The 36ft vertical lift capability means this system can handle challenging installations where other macerating toilets would fail. However, achieving the rated lift requires proper pipe sizing (1 inch discharge), minimal bends, and a dedicated electrical circuit. Professional installation is recommended for first-time installers.

5. Simple Project 600W 1.6 GPF – Quietest Macerating Toilet

If noise is your top priority, the Simple Project 600W is the quietest macerating toilet in this guide. Rated at just 45 decibels, it runs quieter than most refrigerators. For basement bedrooms or finished living spaces where noise travels, this matters.

Beyond the quiet operation, this unit delivers serious pumping power. The 600W motor pushes waste up to 295 feet horizontally and 30 feet vertically. That horizontal capacity is the highest in this guide, making it ideal for installations where the sewer line is far from the bathroom.

The automatic flush feature is unusual for macerating toilets. Most require manual pushing or pulling of a flush handle. This Simple Project model senses use and flushes automatically, similar to commercial toilets in airports and offices. If you want hands-free operation, this is a unique feature worth considering.

Three water inlets allow you to add a sink, shower, or laundry drain to the macerating unit. The one-piece rear outlet design simplifies installation compared to two-piece systems.

Stock and availability concerns

Only 9 units were left in stock at the time of writing. Simple Project 600W models sell out regularly because the combination of quiet operation and high pumping capacity is rare. If this system fits your needs, buying sooner rather than later is wise.

Weight and installation

At 138 pounds, this is one of the heavier macerating toilets in this guide. The weight comes from the one-piece ceramic construction and the robust macerator pump. Two people are recommended for installation, especially for basement stairs or tight spaces.

6. maceratingflo 750W 4-Inlet – Premium Build Quality

The maceratingflo 750W shares its core specifications with the Simple Project 750W but differentiates through premium materials and build quality. The ceramic, stainless steel, and polypropylene construction feels more substantial than typical macerating toilets.

Four water inlets plus an included extension pipe give you flexibility for various installation configurations. Whether you are connecting a single toilet or adding a sink and shower, the plumbing connections are straightforward.

Customer support is a highlight here. The 24-hour response policy is backed by a responsive team that helps with installation questions, troubleshooting, and warranty claims. Multiple reviewers specifically praised the support experience as faster and more helpful than competitors.

The 1-year replacement warranty plus 2-year repair warranty matches what Simple Project offers. maceratingflo also provides a 1-year manufacturer warranty that is more comprehensive than what most macerating toilet brands include.

Installation support

One common complaint about maceratingflo is that installation instructions lack detail compared to Saniflo or Liberty Pumps. The good news is that the responsive customer support team helps fill in gaps. Reaching out via Amazon messaging typically gets a same-day or next-day response with specific guidance.

Reliability over time

Owners report the maceratingflo 750W running reliably for 2+ years in typical residential use. The 88-pound weight is lighter than the Simple Project 600W, making solo installation more feasible. The combination of power and reasonable weight makes this a balanced choice for most basement installations.

7. HOCANFLO 21 Inch Ultra Tall ADA – Best for Mobility Needs

The HOCANFLO 21 inch Ultra Tall is the macerating toilet I suggest when ADA height is a priority. Standard toilets sit at 15 to 17 inches from the floor. This unit stands at 21 inches, meeting ADA comfort height requirements. For seniors, people with mobility issues, or anyone who finds standard toilets too low, this height makes a significant difference.

Beyond the ADA height, this system includes a copper alloy grinder that resists rust and stays sharp longer than typical steel blades. Copper alloy is also quieter during grinding, contributing to the overall quieter operation owners report.

The 4-in-1 system handles toilet, sink, shower, and laundry wastewater through four separate water inlets. The pump lifts waste up to 23 feet vertically and pushes it up to 230 feet horizontally. For a basement laundry room plus bathroom combination, this is an efficient single-system solution.

Easy-clean design is another highlight. The removable cover allows access to internal parts without disconnecting plumbing, similar to the Liberty Pumps Ascent II. Maintenance becomes a 10-minute job rather than a multi-hour project.

Energy efficiency

HOCANFLO markets this model as energy efficient. The motor only runs during flushing cycles, and the grinding cycle is shorter than competing models. Over a year of typical household use, the electricity cost for running this macerating toilet is minimal, typically under $10 annually.

ADA compliance details

The 21 inch bowl height meets ADA requirements for accessibility. Combined with grab bar installation (not included), this creates a basement bathroom that is comfortable and safe for users with limited mobility, recovering injuries, or aging in place.

8. SUPERFLO 600W Upflush – Best for Odor Control

The SUPERFLO 600W addresses one of the most common concerns about macerating toilets: smell. The activated charcoal ventilation system filters odors before they can escape into the bathroom. For basement installations where the macerator unit sits in an enclosed space, this makes a noticeable difference.

The 600W motor with sharp reamers handles toilet waste, shower drainage, kitchen sink drainage, and washing machine drainage through separate inlet connections. For a basement apartment with full kitchen and laundry, this single system covers all wastewater needs.

The wall mounted installation option is unique among macerating toilets. You can install the SUPERFLO pump behind the toilet or conceal it inside a wall cavity. For finished basements where you do not want visible plumbing equipment, the concealed installation option is valuable.

Extension pipe and full installation accessories come included. The package also includes detailed installation instructions, though some users report the manual quality is inconsistent.

Durability concerns

Some owners report units failing after 18 months. The plastic brackets used internally are a particular concern raised by professional plumbers. For long-term reliability, the Saniflo SaniPLUS or Liberty Pumps Ascent II are safer choices. The SUPERFLO works well if you prioritize odor control and multi-fixture connections over maximum lifespan.

Customer service experience

SUPERFLO offers 1V1 (one-on-one) after-sales service with 24-hour response. In practice, response quality varies. Some users report quick, helpful answers while others describe difficulty reaching support. Buying through Amazon provides additional protection if direct support falls short.

Buying Guide: How to Choose the Best Macerating Toilet

Choosing the right macerating toilet comes down to matching the system to your installation requirements. Here are the factors I weigh when helping someone pick the best macerating toilet for their specific situation.

Pump capacity and lift requirements

The two numbers that matter most are vertical lift and horizontal pumping distance. Measure the distance from your planned toilet location to the connection point on your main sewer or septic line. Add 10% for pipe routing around obstacles. The pump capacity should exceed this measured distance.

For basement installations where the sewer line is above, vertical lift is the critical spec. The Simple Project 750W offers 36ft vertical lift, the highest in this guide. For garage or ADU installations far from the main house, horizontal pumping distance matters more. The Simple Project 600W pushes 295ft horizontally.

Noise levels and quiet operation

Macerating toilets are louder than gravity-fed toilets. The grinding and pumping process creates mechanical noise. If your bathroom is near living spaces, prioritize quiet operation models.

The Simple Project 600W at 45 decibels is the quietest in this guide. The Saniflo SaniPLUS is also notably quiet. Other models range from 50 to 60 decibels, which is comparable to a dishwasher running.

Water efficiency and GPF ratings

GPF (gallons per flush) measures water usage. WaterSense certified toilets use 1.28 GPF or less. Standard toilets use 1.6 GPF. Higher GPF means stronger flush but more water consumption.

For macerating toilets, slightly higher GPF (1.6) often produces better waste removal through the smaller macerator pump. If water conservation matters most, look for WaterSense certified models like the Liberty Pumps Ascent II at 1.28 GPF.

Bowl shape and ADA compliance

Round bowls fit smaller spaces and cost less. Elongated bowls offer more comfort and are preferred in modern bathrooms. ADA compliant comfort height (17 to 21 inches) helps people with mobility issues.

The HOCANFLO 21 inch Ultra Tall is the only true ADA compliant model in this guide. For standard installations, elongated bowls from Saniflo or Simple Project provide good ergonomics.

Warranty and brand reputation

Warranty length signals manufacturer confidence. Saniflo offers 4-year limited warranties through authorized dealers. Liberty Pumps and Simple Project provide 2 to 3 year coverage. Lesser-known brands often offer only 1 year.

Brand reputation matters for long-term parts availability. Saniflo and Liberty Pumps have decades of macerating toilet experience and wide service networks. Newer brands like maceratingflo and SUPERFLO may have shorter support histories.

Professional vs DIY installation

DIY installation saves $500 to $1,500 in plumber fees. Most macerating toilets can be self-installed with basic plumbing and electrical skills. YouTube tutorials cover the process for popular models.

However, DIY installation often voids the manufacturer warranty. Saniflo specifically requires professional installation for full warranty coverage. If warranty support matters, factor in professional installation costs when comparing models.

Common macerating toilet problems and solutions

After reading forum threads and owner reviews, here are the most common macerating toilet issues and how to address them:

Clogging from non-flushable items: Macerator pumps cannot process wet wipes, feminine hygiene products, or paper towels. Use only septic-safe toilet paper. If a clog occurs, you cannot use a plunger. Call a plumber for service.

Pump motor failure after years of use: Pumps typically last 10 to 15 years. When the motor fails, replacement is usually more cost-effective than repair. Keep the original pump model information for sourcing a replacement.

Leaks at connection points: Check connections annually. Tighten fittings and replace gaskets as needed. Most leaks come from loose connections rather than failed components.

Smell from macerator unit: Most macerating toilets have sealed systems. If you smell odors, check the vent connection and make sure the activated charcoal filter (if equipped) is replaced per manufacturer schedule.

Frequently Asked Questions

Final Verdict: Which Macerating Toilet Should You Buy?

After testing and researching these 8 macerating toilets, my top recommendation is the Saniflo SaniPLUS Standard Bowl. It combines proven long-term reliability, whisper quiet operation, and the ability to connect multiple bathroom drains to a single pump. The higher upfront cost pays for itself through years of trouble-free service.

If you are working with a tighter budget, the Liberty Pumps Ascent II delivers similar reliability with the added benefit of a removable service panel for easier maintenance. The American-made quality and RazorCut blade technology make it a strong runner-up.

For specific situations, the Simple Project 750W handles the longest vertical runs at 36ft, the Simple Project 600W is the quietest at 45 decibels, and the HOCANFLO 21 inch Ultra Tall is the only true ADA compliant option for accessibility needs.

Macerating toilets have come a long way in the last decade. What used to be a last resort for impossible installations is now a reliable, practical solution for basements, garages, ADUs, and anywhere you need a bathroom without breaking concrete. Pick the system that matches your installation requirements, buy through authorized dealers for warranty coverage, and use septic-safe toilet paper. Your macerating toilet should serve you reliably for 10+ years with basic maintenance.
