The Saniflo SaniPLUS is the best macerating toilet for most installs — the brand that defined the category and the one plumbers actually know how to service. The 750W 4-Inlet system is the value pick when you want a sink and shower on the same pump, and the 21-inch ADA-height model is the comfort-height choice.
How We Picked
We compared macerator motor wattage, how many additional fixtures the pump accepts, vertical lift and horizontal run capability, bowl height, and owner reports on the thing that actually decides satisfaction: whether the pump survives everyday use. We weighted serviceability heavily: a macerator is a mechanical part that will eventually need attention, and a brand your plumber recognizes is worth more than a spec sheet. A macerating toilet is one of several answers to plumbing you don't have — see our composting toilet guide for the no-water approach and our RV toilet picks for mobile setups.
1. Best Overall: Saniflo SaniPLUS Macerating Upflush Toilet Kit, Elongated Bowl
Saniflo SaniPLUS Macerating Upflush Toilet Kit, Elongated Bowl
Saniflo
- The brand that created the upflush toilet category
- Elongated bowl rather than the compact round shape
- Accepts a sink on the same pump
- Replacement parts and service actually available
- Plumbers recognize it — a real advantage when something goes wrong
- 4.6★ from 85+ owners
Why we picked it: Saniflo invented this category and still sets the standard, and in a product with a wearing mechanical part that matters more than any spec. When a no-name macerator fails in year four, you are hunting a discontinued impeller on a marketplace listing; when a Saniflo fails, parts exist and any plumber has seen one before. The elongated bowl is the other quiet win — most upflush toilets come only in the cramped round shape, and you notice the difference every day.
2. Best Value: 750W Macerating Toilet System with 4 Inlets and Extension Pipe
750W Macerating Toilet System with 4 Inlets and Extension Pipe
Upflush
- 750W macerator handles waste and paper reliably
- Four inlets — add a sink, shower, or washing machine
- Extension pipe included for longer runs
- Lifts waste vertically to reach an overhead drain line
- Complete system rather than a pump-only kit
- 4.4★ from 160+ owners, 50+ bought in the past month
Why we picked it: Most people who install a macerating toilet end up wanting a sink beside it, and then a shower — and a single-inlet pump means starting over. Four inlets let one pump serve the whole room, which is what turns a basement toilet into a basement bathroom. At 750 watts the macerator has real margin over the bare minimum, and it ships complete with the extension pipe rather than as a pump you then build a kit around.
3. Best Comfort Height: 21-Inch Tall Macerating Toilet System, ADA Compliant Height
21-Inch Tall Macerating Toilet System, ADA Compliant Height
Upflush
- 21-inch bowl height meets ADA comfort-height standards
- Noticeably easier to sit and stand for most adults
- Integrated macerator pump in the same footprint
- Standard upflush installation — no slab cutting
- Useful for aging-in-place and accessible builds
- 4.3★ from 120+ owners
Why we picked it: Macerating toilets have a reputation for sitting low, because the pump housing has to go somewhere — and standard models often land around 15 inches, which is a real problem for anyone with knee or hip trouble. This one reaches 21 inches, matching ADA comfort height, without giving up upflush capability. If the bathroom is for a parent, a guest suite, or a house you plan to grow old in, that difference outweighs any spec on the pump.

What to Look For in a Macerating Toilet
Motor wattage and what it survives. Macerator motors typically run 400-800 watts. Under about 500W you're relying on users being careful about what goes in the bowl, which is a plan that fails the first time you have guests. 750W handles waste and toilet paper without drama and gives you margin as the impeller wears.
Count your inlets before you buy. A single-inlet pump serves the toilet only. If there's any chance you'll add a sink, a shower, or a laundry to the same room, buy a multi-inlet unit now — retrofitting means replacing the pump entirely, and by then the wall is closed up.
Vertical lift and horizontal run. Manufacturers quote a maximum lift (often 12-15 feet) and a maximum horizontal run (often 100+ feet), but the two trade against each other: every foot you go up costs you several feet of horizontal reach. Map your actual route to the main drain line and check both numbers against it before ordering.
Bowl height. Because the macerator sits behind or under the bowl, many upflush toilets end up lower than a standard fixture. Standard comfort height is 17-19 inches and ADA height is around 21. If the bathroom will serve older users, measure this first — it's the spec people regret ignoring.
Noise and what goes in the bowl. A macerator runs for 10-20 seconds after each flush and is genuinely audible — plan for that if it shares a wall with a bedroom. And be firm about the rules: wipes, feminine products, and paper towels are what kill these pumps, regardless of what the packaging on those products claims.
Bottom Line: Which Should You Buy?
For most installs: the Saniflo SaniPLUS. The category's original brand, an elongated bowl, and parts you can actually get.
For a full bathroom on one pump: the 750W 4-Inlet Macerating Toilet. Four inlets and 750 watts, at well under the branded price.
For comfort and accessibility: the 21-inch ADA Macerating Toilet. Full 21-inch ADA height without giving up upflush capability.

Frequently Asked Questions
What is a macerating toilet?
It's a toilet with a built-in grinder pump. Rather than relying on gravity to move waste down into a drain line, the macerator grinds waste and paper into a slurry and pumps it up and out through a pipe as small as three-quarters of an inch. That's what lets you put a bathroom below the level of your main drain.
How does a macerating toilet work?
When you flush, water and waste drop into a chamber behind the bowl where a fast-spinning blade breaks everything into a fine slurry. A pump then pushes that slurry through a small-diameter pipe — vertically if needed — until it reaches your main drain line, where gravity takes over as usual. The whole cycle takes 10-20 seconds.
Where can you install a macerating toilet?
Anywhere you have water supply and electrical power and a route to a drain line, even if that drain is above the toilet. Typical installs are basements below the sewer line, garage conversions, attic bathrooms, cabin additions, and any room where cutting a concrete slab for gravity drainage would be impractical or expensive.
What are the pros and cons of a macerating toilet?
The advantages are placement freedom, no slab cutting, small-diameter pipe, and a far cheaper install than rerouting drainage. The disadvantages are that it needs electricity (so it stops working in an outage unless you have backup power), it makes noise on every flush, the pump is a mechanical part that will eventually need service, and it is intolerant of anything other than waste and toilet paper.
Do macerating toilets need electricity?
Yes — the macerator and pump both run on household power, so a macerating toilet stops working during an outage. If it's the only toilet in a cabin or basement apartment, put it on your backup power plan. See our home battery backup guide; the intermittent draw of a macerator is a small load for any of those systems.

How We Research
Picks are based on manufacturer specifications, current Amazon availability, and patterns across verified owner reviews. Macerating toilets are a smaller category than most plumbing fixtures, so we weighted brand serviceability and parts availability alongside review volume — confirm lift, run length, and inlet count against your actual installation before buying.
Safety note: Macerating toilets combine water and mains electricity and must be on a GFCI-protected circuit. Check local plumbing codes before installing — some jurisdictions restrict upflush systems or require them to be a permitted installation with an inspection.
