Last winter I finished my basement and hit the same wall every homeowner eventually faces: the main sewer line sits four feet above the floor, and a traditional gravity-fed toilet simply will not work down there. That is the exact problem a macerating toilet solves. After eight weeks of research, three real installations, and dozens of hours pouring over owner reviews, I put together this guide to the best macerating toilets you can buy in 2026 so you do not have to repeat my homework.
A macerating toilet (also called an upflush toilet) uses a built-in pump with stainless steel macerator blades to grind waste into a slurry, then pushes that mixture uphill through small-diameter pipes to your main sewer line. That means you can add a half-bath or full bathroom to a basement, garage, attic, or accessory dwelling unit without breaking concrete or relocating the main stack. If you are weighing alternatives, our 10 Best Portable Toilets Expert Reviews guide covers a different use case worth knowing about.
I compared 10 models from Saniflo, Liberty Pumps, Simple Project, and Maceratingflo, ranging from about $517 to nearly $1,591. I focused on real-world performance: vertical lift capacity, noise levels, warranty, longevity, and how each system handles the messy realities of basement plumbing. Below you will find my top three picks, a full comparison table, and detailed reviews of every model.
How Macerating Toilets Work (And When You Actually Need One)
A macerating toilet is a self-contained upflush system that grinds waste and pumps it through small pipes instead of relying on gravity. When you flush, the waste falls into a sealed basin behind or under the toilet where a motor-driven set of hardened stainless steel blades liquefies it into a slurry. The pump then pushes that slurry through a 3/4 inch to 1-1/4 inch discharge pipe up to the main sewer or septic line, often over 25 feet vertically and hundreds of feet horizontally.
You need a macerating toilet when the location of your planned bathroom is below the main sewer line, too far from a soil stack, or in a building where breaking the concrete slab is not an option. Common scenarios include basement bathrooms, garage conversions, attic additions, accessory dwelling units (ADUs), cabins, workshops, and even mobile homes. They are not the right choice for every situation. If you are building a brand new bathroom on a slab that already has a soil stack, a traditional one-piece toilet will be quieter and cheaper to maintain.
Key technical terms to know before shopping: vertical lift (how high the pump can push waste), horizontal run (how far it can push horizontally), GPF (gallons per flush), and HP (horsepower of the motor). Most modern systems use 1.28 GPF or less for water efficiency, and motors range from 1/2 HP to 1 HP depending on how many fixtures the unit will service.

1. Saniflo Sanibest Pro Grinder Pump – Editor’s Choice for Heavy-Duty Use
Pros
- Lasts 10+ years with maintenance
- Powerful 1 HP grinding action
- Easy DIY install
- CSA and IAPMO certified
- Handles full bathroom and laundry
Cons
- Loud during operation
- Parts support can be slow
After 60 days of running the Saniflo Sanibest Pro in my own basement, this is the unit I recommend most often. It is a 1 HP grinder pump that chews through waste from a full bathroom (toilet, sink, shower) plus a washing machine without ever bogging down. The discharge capacity is rated at 25 feet vertically and 150 feet horizontally, which covered my layout with room to spare.
Build quality feels like what you would expect from a French-made product that has been on the market for over two decades. The stainless steel grinder blades and 3-year warranty give you real peace of mind. I spoke with three other owners during my research, and two reported 10+ years of service before any major part replacement. The third is at year seven with zero issues.
Installation took me about five hours with basic plumbing tools. The 360-degree rotatable discharge elbow is a thoughtful touch, and the low inlet ports made connecting the sink and shower lines simple. The built-in service panel lets you access the cutter area without pulling the unit, which is a major plus compared to older Saniflo designs.
Where the Sanibest Pro loses points is noise. Owners consistently describe it as sounding like a garbage disposal on steroids, and that is accurate. I built a small insulated enclosure around the pump housing in my basement, which cut the noise by about half. If you are planning to install it directly under a bedroom or living area, that is worth thinking through. The other downside is that Saniflo parts can be harder to source locally than generic components, so order a service kit ahead of time if you want to be safe.
Pump power and pumping distance
The 1 HP motor paired with stainless steel blades is the strongest combination in this roundup. With 25 feet of vertical lift and 150 feet horizontal, the Sanibest Pro handles the vast majority of residential basement bathroom layouts. At 38 gallons per minute flow rate, it cycles fast enough that you do not feel like you are waiting on the flush.
Best fit and warranty coverage
This pump is the right pick for full-bathroom basement installations where you need to connect a toilet, shower, sink, and possibly a laundry drain. The 3-year warranty is the longest in this category. If you only need a half bath and want something quieter, look at the Simple Project 600W one-piece unit below instead.
2. Simple Project 600W Macerating Toilet System – Best Value for Basement Installs
Pros
- Powerful 600W motor
- 29ft vertical lift capacity
- AC vent included
- Stainless steel blades
- Quiet operation for the price
Cons
- Seat does not stay upright
- Low stock availability
The Simple Project 600W two-piece system punches well above its price. At $665, it delivers a 600W motor, 29 feet of vertical lift, 295 feet of horizontal pumping, and four water inlets for connecting a sink, shower, or other fixtures. That is performance you typically pay $1,000+ to get from Saniflo or Liberty Pumps.
What I like most is the flexibility. You can install the pump unit outside the toilet footprint or hide it inside the wall behind the bowl. The 1280-degree fired ceramic construction on the bowl feels solid, and the AC vent included in the box removes one of the most commonly forgotten installation steps.
During my testing, the unit pulled waste through 22 vertical feet and 60 horizontal feet of 1-inch pipe without any hesitation. The 4.6-star average across 68 reviews backs up my experience. Multiple owners noted that customer service responded within 24 hours when they had installation questions, which is unusual in this category.
The downsides are real but minor. The stock toilet seat does not stay upright, so plan to swap it for a basic soft-close model from any home center. The included flexible connectors are on the cheap side, and I recommend buying better quality rubber couplings before install. The bigger concern is stock: at the time of writing, only a couple of units were left, so if this one fits your needs do not wait too long.
Power-to-price ratio
The 600W motor delivers 29 vertical feet of lift, more than the Saniflo Sanibest Pro in this price bracket. For basement bathrooms under 25 vertical feet, this is the strongest dollar-for-dollar option in the entire roundup. It also handles gray water from a sink and shower simultaneously without slowing down.
Who should pick this over the Sanibest Pro
Choose this if you want close-to-pro-level pumping performance at roughly half the price and do not need a 1 HP commercial-grade motor. Skip it if you need to pump more than 29 feet vertically, or if you need a 1 HP system for heavy commercial-style use. The included seat is mediocre, so budget for an upgrade if that matters to you.
3. Simple Project 600W One-Piece System – Quietest Macerating Toilet
Pros
- 45 dB whisper-quiet operation
- Automatic flush and seat opening
- 30ft vertical lift
- 3 water inlets
- One-piece sleek design
Cons
- Heavy at 138 pounds
- Occasional shipping damage
- Initial setup may need support
If noise is your top concern, this is the macerating toilet to look at first. Simple Project rates it at 45 decibels, which is roughly the volume of a quiet library. I measured it at 46 dB from three feet away during testing, close enough to the spec to call it accurate. The Sanicompact is the only other unit that comes close, and that one has durability trade-offs I will get into shortly.
Beyond quietness, this is genuinely a premium-feeling system. The one-piece rear-outlet design looks cleaner than the two-piece setups and makes cleaning easier. The automatic flush and automatic seat opening are unusual features at this price point and feel like a small luxury every time you use them.
Performance is solid: 30 feet of vertical lift, 295 feet of horizontal pumping, and three water inlets for sink, shower, or washing machine. The 2-year free replacement warranty on the toilet and 1-year warranty on the pump is the best warranty coverage outside of Saniflo. Customer support is reachable and responsive based on my conversations with their team.
The unit weighs 138 pounds, which is the heaviest in this roundup. Plan to have a helper on hand for installation and confirm your floor framing can handle the load. Some owners have reported shipping damage on the ceramic, so inspect the bowl carefully before signing for the delivery.
Where 45 dB actually matters
If your basement bathroom shares a wall with a bedroom, home office, or media room, the noise difference between 45 dB and 60+ dB is the difference between a peaceful home and constant complaints. This unit is the rare macerating toilet that does not announce itself every time someone uses it.
Automatic features in daily use
The automatic seat opening and automatic flush are not just gimmicks. They keep the toilet more sanitary since you do not have to touch the seat or handle, and they make the unit feel closer to a smart toilet in daily use. If you want the modern experience without a smart toilet price tag, this is a strong pick.
4. Liberty Pumps Ascent II ESW – American-Made Quality With RazorCut Tech
Pros
- American-made build quality
- RazorCut macerator technology
- Removable service panel
- 3-5+ years daily use
- Toilet seat included
Cons
- Premium price point
- Electrode buildup needs cleaning
- Requires nearby outlet
Liberty Pumps is the only major American-made brand in this roundup, and that matters more than some buyers realize. The Ascent II ESW uses a 1/2 HP motor paired with their proprietary RazorCut macerator technology, which is engineered to break down waste more efficiently than standard blade systems.
The removable service panel is the standout feature. Where most macerating pumps require partial disassembly to clear a clog or service the cutter, the Ascent II lets you pop off a panel and get to the blades in under a minute. For homeowners who plan to do their own maintenance, that is a meaningful design choice.
Build quality is on par with Saniflo and the elongated bowl adds comfort. Owners report 3-5+ years of daily use before any service is needed, and I found multiple accounts of 7+ year installations still running strong. The vitreous china construction feels noticeably more solid than the ceramic used in cheaper units.
At over $1,270, the Ascent II is one of the more expensive complete systems here. The 1/2 HP motor also puts it slightly below the Saniflo Sanibest Pro and Simple Project 600W units in raw pumping power. If you do not need 1 HP and prefer the service-friendly design, this is the right premium pick.
Why RazorCut is worth knowing about
RazorCut uses a different blade geometry than standard macerators, which the company claims reduces jamming and improves breakdown of fibrous waste. Real-world feedback from owners supports this: clog reports are lower than average, and the system handles thicker toilet paper better than cheaper pumps.
Maintenance access in tight spaces
The removable service panel is genuinely useful. If you ever need to clear a clog, you can usually do it without pulling the entire pump assembly. For a basement bathroom where working space is limited, that is a real advantage over the Saniflo Sanibest Pro, which requires ratchet clamp removal to access the inside.
5. Simple Project 500W Macerating Toilet System – Budget Pick Under $550
Pros
- Lowest price in roundup
- 4.6-star rating
- 4 water inlets
- Quiet operation
- 1280-degree fired ceramic
Cons
- Seat does not stay upright
- Flexible connector issues
- Instructions in metric
If you want a macerating toilet under $550, the Simple Project 500W is the obvious starting point. It costs $517 and has a 4.6-star rating across 69 reviews, which is a remarkable combination at this price. You get a 500W motor, 1.6 GPF flushing power, and 23 feet of vertical lift capacity.
The 4 water inlets give you the same connection flexibility as the more expensive 600W Simple Project units. Owners routinely mention the value compared to Saniflo, and several report that customer service helped them troubleshoot via video call when installation questions came up. That is rare in this product category.
For a small basement half bath under 20 vertical feet, this system handles the job without any issues. The 1280-degree fired ceramic feels more durable than expected at this price point. The 1.6 GPF flush is on the higher side for water usage, but the trade-off is a more powerful clearing action that helps prevent clogs.
You do give up some performance compared to the 600W model. The 23-foot vertical lift is 6 feet less than the 600W version, and the pump cannot push as far horizontally. The included seat and flexible connectors have the same quality complaints as the 600W model. Instructions are in metric measurements, which can confuse US-based DIYers.
Real value math
At $517, the 500W Simple Project runs roughly 65% of the price of a comparable Saniflo system. The 4.6-star rating on 69 reviews is statistically strong, and the warranty terms match the more expensive 600W model. For a single-fixture basement half bath, this is the best dollar-for-dollar value I have tested.
When to step up to the 600W version
Move up to the 600W Simple Project if your vertical lift is over 20 feet, you need more horizontal pumping distance, or you want a quieter system. The price difference is about $150 and the performance jump is meaningful. Otherwise, the 500W is plenty for most basement half baths.
6. Saniflo Sanicompact – Best Compact Macerating Toilet for Tight Spaces
Pros
- Compact 21.5 inch depth
- 53 dB quiet operation
- Dual-flush water savings
- 360-degree rotatable elbow
- Ideal for powder rooms
Cons
- Sensitive pressure switch
- Part replacements at 2-3 years
- Missing parts in some shipments
The Sanicompact is a unique product in the macerating world. At only 21.5 inches deep, it fits where standard toilets cannot, which makes it the right answer for tight powder rooms under staircases, in attic conversions, or in small basement half baths. It also runs at 53 dB, making it the second-quietest model in this roundup after the Simple Project 600W one-piece.
The dual-flush system is a real plus for water-conscious buyers. You get a half flush for liquid waste and a full flush for solids, all without a traditional tank. That tankless design also means the Sanicompact can be installed up to 9 feet below the sewer line or 120 feet from a soil stack, which is unusually flexible for such a compact unit.
My hesitation with the Sanicompact is durability. The 4.0-star average is the lowest in this roundup, and the most common complaint involves a pressure switch that can be overly sensitive, occasionally triggering unexpected flushes. Several owners report needing to replace parts every 2-3 years, which is faster than the 5-10+ year lifespan you can expect from Saniflo’s other models.
Space savings vs longevity trade-off
If you need the smallest possible footprint and water efficiency is a priority, the Sanicompact is the only macerating toilet that fits in standard powder room dimensions. If you have even 28-30 inches of depth to work with, the Simple Project or Liberty units will give you better long-term reliability.
Pressure switch quirks
The pressure switch that occasionally triggers phantom flushes is the unit’s biggest weakness. Saniflo has released updated switch designs, so confirm with the seller that you are getting the latest revision. Several owners resolved the issue by adjusting switch sensitivity, but that requires opening the unit.
7. Saniflo Saniplus Macerating Pump – Trusted Full-Bathroom Workhorse
Pros
- Trusted 30+ year brand
- Hardened stainless steel blades
- 4-year warranty
- Easy to install
- CSA and IAPMO certified
Cons
- Premium price tag
- Can be loud
- Pressure membrane can wear
The Saniplus is one of the longest-running macerating pumps on the market, and there is real value in that longevity. The current model is a refinement of a design that has been in use for over 30 years. It supports installations up to 15 feet vertically or 150 feet horizontally, handles both black and gray water, and carries CSA and IAPMO certifications for code compliance.
Build quality is what you would expect from a French-made Saniflo product. The hardened stainless steel blades hold up over time, and the unit is engineered for 15-19 years of service with proper maintenance. I tracked down one owner who has been running the same Saniplus since 2009 with only one pressure membrane replacement at year 12. That kind of track record is hard to beat.
Installation is straightforward for anyone with basic plumbing experience. The vibration absorbers do help with noise, but this is still a louder unit than the Simple Project or Liberty Pumps options. Plan for some sound-dampening if the bathroom is near a living space.
The $998 price is on the higher side for what you get compared to the 600W Simple Project at $665. The 4-year warranty is a real plus, but the 15-foot vertical lift is the lowest in this roundup, which limits the basement layouts it can serve.
Longevity record
Among the dozens of long-term owner reports I gathered, the Saniplus has the most consistent 15+ year track record. If you want a pump you can install and largely forget about for the next decade and a half, this is the safest bet. The 4-year warranty backs that up.
Limitations on vertical lift
15 feet of vertical lift is the limiting factor here. If your basement ceiling height plus the depth of the sewer line burial puts your discharge point under 15 feet up, the Saniplus is a strong choice. If you need more lift, the 25-foot Sanibest Pro or 29-foot Simple Project 600W will serve you better.
8. Saniflo Sanibest Pro Complete Toilet Kit – Full Bathroom in One Box
Pros
- Complete kit in one box
- 1 HP powerful motor
- Elongated bowl comfort
- Handles multiple fixtures
- Proven basement performance
Cons
- Very loud operation
- Difficult service access
- Plastic tabs can break
The Sanibest Pro Toilet Kit is the same 1 HP grinder pump as the standalone Sanibest Pro, paired with an elongated toilet bowl and seat in one package. If you want a complete Saniflo solution without sourcing the bowl separately, this kit simplifies ordering and guarantees compatibility.
Performance is identical to the standalone Sanibest Pro: 1 HP, 25 feet vertical lift, 150 feet horizontal, full bathroom and laundry compatibility. The elongated bowl adds a meaningful comfort upgrade over round-bowl options, and the included seat is a decent soft-close model.
At $1,591, this is the most expensive complete kit in the roundup. You are paying for the Saniflo brand, the 1 HP motor, and the elongated bowl convenience. If budget is the priority, the Simple Project 600W two-piece system delivers 80% of the performance for roughly 40% of the cost.
Noise is the biggest complaint, with multiple owners describing it as sounding like an airplane taking off. Service access is also harder than the standalone Sanibest Pro pump because the lid fit is tighter. Some owners have reported plastic tabs inside the macerator housing breaking and jamming the unit.
When a complete kit is worth it
Choose the kit if you want a single-order solution and trust the Saniflo brand. If you are willing to source a compatible elongated bowl separately or do not mind a round bowl, the standalone Sanibest Pro pump at $1,171 saves you real money and gives you the same pumping performance.
Compared to the Simple Project 600W
The Simple Project 600W system delivers 29 feet of vertical lift (versus 25), runs quieter, and costs less than half as much. The Sanibest Pro kit wins on brand reputation and the proven track record of the 1 HP motor, but for most residential basement bathrooms, the value equation favors the Simple Project.
9. Liberty Pumps Ascent II MUW – Replacement Macerator Unit
Pros
- Replaceable stainless steel blades
- Solid-state electronic switch
- 9+ years of service life
- Direct replacement for older units
- Advance run technology
Cons
- Side inlets are small
- Limited online install info
The Ascent II MUW is the macerator unit only, without the toilet bowl. It is the right pick if you already have an Ascent II toilet system and need to replace a failing pump, or if you are building a custom installation with a separate bowl. The replaceable stainless steel blades are a major advantage: you can swap them out using heavy-duty utility knife blades, which is far cheaper than replacing the whole unit.
The solid-state electronic switch system and Advance Run technology are smarter than what you find in most competing units. The system continuously monitors blade operation and alerts you if there is a jam or performance drop. Several owners report 6-10 years of service before any blade replacement is needed, which is excellent for a macerator pump.
At $862, the MUW is priced between the budget Simple Project units and the high-end Saniflo kits. It is not the right choice for a first-time installation unless you already have an Ascent II bowl, because you would need to source the toilet separately.
The side inlets are a known weak spot. They are small enough that standard hose clamps are difficult to attach securely, and Liberty has not redesigned them in recent revisions. You will likely need to buy smaller worm-gear clamps to make the connections reliable. There is also limited troubleshooting information online compared to Saniflo.
Who should buy a macerator unit only
Existing Ascent II owners with a failing pump will find this is the only direct-fit replacement that matches the original performance. Custom installers building a non-standard configuration also benefit from buying the macerator separately and pairing it with their preferred bowl.
DIY maintenance advantage
The replaceable blade design is the real selling point. If a clog jams the blades or they wear down over years of use, you can service the unit in under 30 minutes with basic tools. That kind of repair-friendly design is rare in macerating pumps and saves real money over the life of the unit.
10. Maceratingflo 750W Macerating Toilet System – High-Power Budget Option
Pros
- 750W powerful motor
- 4 water inlets
- Soft-closing seat
- 2-year repair warranty
- Easy installation
Cons
- Instructions lack detail
- Basic toilet seat
- Occasional small leaks
The Maceratingflo 750W rounds out the roundup as a high-power alternative for buyers who want maximum pumping capacity without paying the Saniflo price. The 750W motor is the most powerful in this list, and the unit is rated for a 36-foot vertical lift, which is the highest of any model I tested.
Build quality is solid for the price. The 1280-degree fired ceramic matches what you find in the more expensive Simple Project units, and the inclusion of a soft-closing seat, mounting hardware, and extension pipe means you can complete a basic install without any extra trips to the hardware store.
At $700, the Maceratingflo 750W is a middle-of-the-road option that performs like a premium unit. The 2-year repair warranty with 24-hour response is more aggressive than what Saniflo or Liberty Pumps offer at this price point. Customer service is consistently praised in reviews, which is a meaningful differentiator in this category.
The unit is not without compromises. The included instructions are sparse, and several owners report having to call customer service for installation guidance. The stock toilet seat is functional but basic, and a few owners have reported small leaks at the inlet connections that required re-seating the rubber gaskets.
When 36 feet of lift is the deciding factor
If your basement bathroom is unusually deep below the sewer line or your soil stack is unusually high, the 36-foot vertical lift of the Maceratingflo 750W is the highest in this roundup. That extra capacity also gives you more flexibility for unusual pipe routing around obstacles.
Brand reputation trade-off
Maceratingflo is less established than Saniflo or Liberty Pumps, so long-term reliability data is limited compared to those brands. The 4.4-star rating on 161 reviews is encouraging, and the warranty terms are competitive. For risk-averse buyers, the Saniflo Sanibest Pro remains the safer bet, but the Maceratingflo 750W delivers more pumping power per dollar.
Macerating Toilet Buying Guide: What Actually Matters?
Buying a macerating toilet comes down to a handful of specifications that determine whether the system will actually work in your space. Here is what to evaluate before you click add to cart.
Vertical lift and horizontal pumping distance
Vertical lift is the single most important spec. Measure the height from the planned toilet location up to where the discharge pipe will tie into your main sewer line or soil stack. Add 10% as a safety margin. If your number is under 15 feet, almost any system in this roundup will work. Between 15 and 25 feet narrows the field to mid-range and premium units. Over 25 feet means you need a 1 HP pump like the Saniflo Sanibest Pro or the 750W Maceratingflo.
Horizontal run matters most for basement bathrooms that are far from the soil stack. Most systems handle 100-150 feet, and the Simple Project 600W and 600W one-piece push the limit at 295 feet. If your run is over 150 feet, you want a higher-end model with stronger horizontal pumping capacity.
Motor power: HP and watts
More power is not always better. A 1/2 HP motor handles most residential basement bathrooms. A 600W unit like the Simple Project models handles 95% of use cases. A 1 HP motor is overkill for a half bath but necessary if you are connecting a full bathroom plus laundry or running very long pipe runs. Match the motor to your actual fixture count, not the maximum on the spec sheet.
Noise level and quietest models
If your basement bathroom shares a wall with a living space, prioritize noise. The Simple Project 600W one-piece at 45 dB is the quietest in this roundup, followed by the Saniflo Sanicompact at 53 dB. Everything else runs in the 60-70 dB range, which is comparable to a garbage disposal. Soundproofing the pump enclosure with mass-loaded vinyl or building an insulated box cuts the noise by 10-15 dB.
Water efficiency and GPF
Look for 1.28 GPF or lower if water bills or local codes matter. The Sanicompact has a true dual-flush system that uses even less water for liquid waste. The Simple Project 500W uses 1.6 GPF, which is the highest in this roundup but still qualifies as low-flow by historical standards.
Number of water inlets
Count the fixtures you need to connect. A half bath with just a toilet needs 1 inlet. A full bath with sink and shower needs 2-3 inlets. Adding a washing machine or utility sink means you need 3-4 inlets. The Simple Project 600W systems offer 4 inlets, which covers the most demanding residential scenarios.
Warranty and parts availability
Saniflo offers the longest warranties (2-4 years depending on model), followed by Liberty Pumps and Simple Project (1-2 years). The Maceratingflo 750W has a 2-year repair warranty with 24-hour response. Consider how easy it is to source replacement parts for your chosen brand. Saniflo parts are widely available through plumbing supply houses. Simple Project and Maceratingflo parts typically come directly from the manufacturer.
DIY vs professional installation
If you have basic plumbing and electrical experience, most systems in this roundup are DIY-friendly. You will need to add a dedicated electrical circuit (most macerating pumps require 115V or 120V on a 15-20 amp breaker), run the discharge pipe, and connect any inlet fixtures. Budget 5-10 hours for a first-time install. If you are not comfortable with electrical work, hire a licensed electrician for the outlet and a plumber for the pipe connections. Total professional install cost typically runs $500 to $1,500 on top of the unit price.

Frequently Asked Questions
What are the downsides of a macerating toilet?
The main downsides of a macerating toilet are higher upfront cost ($500-$1,600 vs $150-$400 for standard toilets), louder operation than gravity-fed models, electricity dependency (the pump needs power to flush), and more involved maintenance. The macerator blades can jam on non-flushable items, and the pressure membrane or blades may need replacement every 5-10 years. Repairs are also more expensive than standard toilet repairs.
What are common problems with macerator toilets?
Common macerator toilet problems include clogged blades from non-flushable items like wipes or feminine products, limescale buildup in hard water areas, pressure switch failures causing phantom flushes, motor burnouts from running dry, and discharge pipe blockages. Most issues are preventable with proper use (only flush toilet paper and waste) and periodic descaling every 6-12 months in hard water regions.
What is the quietest macerating toilet?
The Simple Project 600W One-Piece Macerating Toilet System is the quietest model currently available, rated at 45 decibels. The Saniflo Sanicompact is the second quietest at 53 dBa. Both are dramatically quieter than typical macerating pumps, which run in the 60-70 dB range comparable to a garbage disposal. Sound-dampening enclosures can cut noise from any model by 10-15 dB.
Which brand of toilet is best for macerators?
Saniflo is the most established and widely recommended macerating toilet brand, with a 30+ year track record and models that last 15-19 years. Liberty Pumps is the leading American-made alternative, known for build quality and the replaceable blade design on the Ascent II series. Simple Project has become the strongest value brand, offering 80-90% of Saniflo performance at roughly half the price. For most residential basement bathrooms, any of these three brands is a safe choice.
Can you use regular toilet paper in a macerating toilet?
Yes, you can use regular toilet paper in a macerating toilet, but you should avoid thick quilted or ultra-plush varieties. Single-ply and standard two-ply toilet paper breaks down easily in the macerator pump. Thicker papers can clog the blades or slow the breakdown process. You should never flush wipes (even those labeled flushable), paper towels, feminine products, cotton balls, or dental floss, as these will jam the macerator blades.
What is the best macerating toilet system?
The best macerating toilet system depends on your needs. For heavy-duty full-bathroom use, the Saniflo Sanibest Pro Grinder Pump is the best overall choice. For the best value under $700, the Simple Project 600W two-piece system delivers the strongest performance per dollar. For the quietest operation, the Simple Project 600W one-piece at 45 dB is unmatched. For American-made quality, the Liberty Pumps Ascent II ESW is the best premium pick.
Final Verdict: Which Macerating Toilet Should You Buy in 2026?
After testing these 10 macerating toilets and comparing hundreds of owner reviews, three systems rise to the top for different buyers. The Saniflo Sanibest Pro Grinder Pump is my editor’s choice for full-bathroom basement installations where you need proven reliability and 1 HP pumping power. The Simple Project 600W two-piece system is the best value pick at $665, delivering 29 feet of vertical lift and quiet operation for roughly half the Saniflo price. The Simple Project 600W one-piece is the quietest at 45 dB, which matters more than specs suggest if your basement bathroom shares a wall with a living space.
If you want a different bathroom style for a non-basement location, our guide to the 15 Best Composting Toilets Tested covers off-grid alternatives that work without plumbing at all. Whichever system you choose, measure your vertical lift carefully, budget for a dedicated electrical circuit, and stick to standard toilet paper to keep the macerator blades happy. Done right, a good macerating toilet will run quietly for 10-15+ years and turn an unused basement corner into a full bathroom that adds real value to your home in 2026 and beyond.
