Our Picks: Best Toilet With Built In Macerator reviews
1. SUPERFLO 600W One-Piece Macerating Toilet: Best for a Compact Basement Bathroom
This SUPERFLO system pairs a one-piece toilet with a 600W macerator pump. Its rear outlet is designed to connect with the pump, making the unit a candidate for basement bathrooms and remodels where a conventional gravity drain is difficult to add.
The system has three inlets: one for the toilet and two for other fixtures, such as a sink, shower, or bathtub. That can be useful if you want one pump to serve more than the toilet, but you’ll need to confirm that your planned connections and discharge route match the installation instructions. The pump also includes an activated carbon filter intended to help reduce odors.
One unusual installation detail is that the manufacturer describes this as a sealed, non-bolted floor installation rather than a traditional toilet-bolt setup. That may affect how you plan the floor connection and service access. Its product information does not specify pumping distances, so it may be less suitable than options with a stated vertical and horizontal range if your drain is far away.
Pros:
- One-piece toilet and integrated 600W pump
- Two additional inlets for compatible bathroom fixtures
- Activated carbon filtration is included
- Designed for basement and retrofit installations
Cons:
- No vertical or horizontal pumping distance is stated in the supplied product details
- The sealed, non-bolted installation differs from a typical toilet setup
Verdict: Choose this SUPERFLO if you want a one-piece toilet with extra fixture connections and can confirm that its sealed installation method suits your floor and plumbing plan.
2. PROMAX Macerating Toilet System: Best for Multiple Drain Connections
The PROMAX is a floor-mounted upflush system with a separate macerator pump and a pre-assembled toilet tank. Its most notable feature is four inlets, which the product details describe as suitable for connecting drains from fixtures such as a sink, shower, or laundry line. Check the manual before planning a combined installation, since the exact permitted connections and setup matter.
The manufacturer lists pumping capacity up to 23 feet vertically or 230 feet horizontally through small pipes. Those figures make this model worth considering when the main drain is not close by, but they should not replace a review of your actual pipe route, fittings, and installation limits. The toilet has an elongated ceramic bowl, a 17.7-inch stated height, a soft-close seat, and a pre-assembled tank.
The listed package includes a hardware kit and a 12-month warranty. Compared with the one-piece models in this group, this system has a more traditional separate tank-and-bowl look. Its four-inlet layout is useful only if you need those connections; if you’re adding a toilet alone, a simpler system may be enough.
Pros:
- Four inlets for connecting compatible additional drains
- Manufacturer states pumping distances up to 23 feet vertically or 230 feet horizontally
- Elongated ceramic bowl and soft-close seat
- Product details list a 12-month warranty and installation hardware
Cons:
- More connections can make planning and installation more involved
- Confirm the stated height, inlet sizes, and route limits for your specific project
Verdict: The PROMAX is a strong option to investigate if your bathroom needs several drain connections or a longer discharge route, provided its installation limits fit your plumbing plan.
3. SUPERFLO 600W Upflush Toilet System: Best for Added Odor-Control Features
This SUPERFLO model is a 600W upflush system intended for locations where the toilet sits below or away from the main waste line. Its product information highlights a quiet-operation design and an activated-charcoal ventilation feature. These are useful features to investigate for a basement bathroom, though the listing does not provide a noise measurement or detailed odor-control test results.
The system is described as supporting a toilet, shower, kitchen sink, and washing machine. That range may make it appealing for a more complete utility or basement bathroom, but the product details do not give specific inlet sizes or pumping distances. Confirm which fixtures can be connected at the same time and what pipe arrangement is required before buying.
The listing says the system includes accessories and installation instructions, and it recommends using a licensed plumber. It also describes installation behind the toilet or concealed in a wall using an extension pipe, with access ports recommended. That access guidance matters: a pump should remain reachable for service rather than being permanently closed behind a finished wall.
Pros:
- 600W pump is designed for upflush use
- Activated-charcoal ventilation is listed as an odor-control feature
- Designed to handle several types of fixture drains
- Product details include installation instructions and accessories
Cons:
- Specific pumping distances and inlet sizes are not provided in the supplied details
- Concealed installation requires a plan for future access to the pump
Verdict: Consider this SUPERFLO if its charcoal ventilation and multi-fixture design match your priorities, but verify the pipe limits and service-access needs before installation.
4. Simple Project 600W One-Piece System: Best for a Basic Basement Bathroom Addition
Simple Project combines a one-piece toilet with an integrated 600W macerator pump. The system is intended to grind waste and toilet paper before pumping the slurry through smaller pipes, which can help when a new bathroom cannot use a conventional gravity drain. Its compact, skirted shape is designed to fit a range of basement and remodeling layouts.
The product details say that some configurations can connect additional plumbing, such as a sink, shower, or bathtub. They do not specify the number of inlets or the maximum pumping distance, so this model is best assessed as a potential fit for a relatively direct installation unless the seller or manual confirms more. The listing also describes a cutting mechanism intended to help reduce clogs, but it does not provide independent performance data.
This unit may appeal to a handy homeowner, but a macerating toilet still needs careful plumbing and electrical planning. The product description recommends installation instructions and describes the setup as straightforward; that does not guarantee a simple fit in every bathroom. Confirm clearances, outlet location, discharge route, and access for maintenance before committing.
Pros:
- One-piece toilet with an integrated 600W pump
- Designed for basement and remodeling projects without extensive floor excavation
- Compact, skirted design
- Product details describe support for additional bathroom fixtures on compatible setups
Cons:
- Inlet count and maximum pumping distance are not stated in the supplied details
- Confirm whether your intended extra-fixture connections are supported
Verdict: This is a reasonable candidate for a simple basement toilet installation if the seller can confirm that its discharge limits and fixture connections suit your layout.
5. INEFLO 600W Tankless Upflush Toilet: Best for a Tight Space or Longer Drain Route
This INEFLO model is a tankless, one-piece upflush toilet with a built-in 600W pump. Its listed dimensions are about 20.86 inches long, 13.18 inches wide, and 18.11 inches high, making it one of the more clearly specified choices for shoppers working with a small footprint. Measure your available space carefully and allow room for the required plumbing connections and servicing.
The manufacturer states that the pump can move waste up to 26 feet vertically or 260 feet horizontally. It also lists a copper-core motor, stainless-steel macerator blade, and reinforced ABS housing. These are useful specifications to compare, but the stated maximum distances are not a substitute for checking the route, pipe size, and installation instructions for your project.
The system has a touch flush button and automatic start-and-stop operation. Its title advertises dual flush, but the supplied description does not explain the flush options in detail, so confirm how that feature works before purchase. The product information also says it can serve a basin and toilet together; it does not describe support for a larger group of fixtures. A 12-month manufacturer warranty is listed.
Pros:
- Compact dimensions are provided for space planning
- Manufacturer states pumping distances up to 26 feet vertically or 260 feet horizontally
- Tankless, one-piece design with automatic pump operation
- Product details list a 12-month manufacturer warranty
Cons:
- Supplied details describe toilet-and-basin use, not a larger multi-fixture setup
- Confirm the advertised dual-flush function and installation requirements with the seller
Verdict: The INEFLO is the most compelling option here for a very small bathroom or a route that needs the longer stated pumping range, as long as its tankless design and confirmed flush features suit you.
How to Choose a Toilet With a Built-In Macerator
Measure the full discharge route
Map the route from the pump to the drain, including both vertical lift and horizontal distance. Compare that route with the manufacturer’s stated limits, and check the required pipe size, fittings, and layout in the installation manual. A product’s maximum distance is a specification to verify, not a promise that every route will work.
Decide which fixtures the pump needs to serve
If you only need a toilet, a system with multiple extra inlets may offer little benefit. If you plan to add a sink, shower, or laundry drain, look for the number of inlets and the types of fixtures the manufacturer allows. Confirm whether simultaneous use is supported and whether separate equipment or specific pipe sizes are required.
Choose a toilet shape and installation style
One-piece models combine the bowl and tank in a streamlined unit, while a separate tank-and-bowl design may feel more familiar. Compare the product’s dimensions with your room, and check outlet position, seat height, and clearances. Pay special attention to unusual mounting or sealing instructions, such as a non-bolted floor connection.
Plan access for service and repairs
The pump may need inspection or maintenance. If it will be placed behind a toilet or concealed in a wall, follow the manufacturer’s access guidance and avoid closing it in without a way to reach it. Consider the service location before finishing walls or building cabinetry around the system.
Check ventilation and odor-control details
Some listed models describe activated carbon or charcoal features, but the supplied descriptions do not give independent test results or exact odor-control performance. Check whether the system needs a particular vent connection and follow its manual. Do not assume a filter replaces any ventilation required for your installation.
Confirm electrical and plumbing requirements
A macerating toilet relies on a pump, so check the electrical requirements and outlet location in the installation documents. Make sure the plumbing connection and discharge route match the system’s instructions. If you are unsure about the pipe layout, electrical setup, or local requirements, ask a licensed plumber or electrician to review the plan.
Compare warranty and included parts
Check what comes in the box, including the toilet, pump, seat, fittings, valves, and installation hardware. Read the warranty terms to see what is covered and what support is available. The product descriptions for some models list a 12-month warranty, but you should confirm the current terms before ordering.
Frequently Asked Questions
What does a toilet with a built-in macerator do?
A macerator grinds toilet waste and toilet paper into a slurry, then a pump moves it through a discharge line. This can make a bathroom possible where a standard gravity drain is difficult to install, such as some basement spaces.
Can a macerating toilet connect to a sink or shower?
Some systems have extra inlets for additional fixtures. The number and type of connections vary by model, so check the manual for approved fixtures, pipe sizes, and any limits on simultaneous use.
How far can an upflush toilet pump waste?
It depends on the system and the plumbing route. For example, the PROMAX listing states up to 23 feet vertically or 230 feet horizontally, while the INEFLO listing states up to 26 feet vertically or 260 feet horizontally. Confirm the permitted pipe layout and fittings in the product instructions before relying on those maximum figures.
Does a macerating toilet need special installation?
It needs a suitable discharge line, a power connection, and installation that follows the manufacturer’s instructions. Floor mounting and sealing methods can differ, and some models may need extra planning for pump access. A plumber can help confirm whether your layout is suitable.
Can the pump be hidden behind a wall?
Some systems are designed to be installed discreetly or concealed, but the pump should remain accessible for service. Follow the product’s instructions about access ports and clearances before closing in any part of the installation.
Are these systems a good choice for a basement bathroom?
They can be a useful option when the bathroom is below or far from the main waste line and a conventional gravity drain is not practical. Suitability depends on the discharge route, fixture connections, electrical setup, and installation requirements for the specific model.
Final Recommendation
For a compact toilet with multiple potential fixture connections, the SUPERFLO 600W one-piece system is worth considering, provided its sealed, non-bolted installation method works for your project. If you need several drain connections or a longer stated pumping range, compare the PROMAX and INEFLO specifications carefully. Before ordering any of these systems, confirm the current listing details, installation instructions, and plumbing requirements against your actual bathroom plan.
