Best Toilets for Basements (Upflush and Standard Picks)

Putting a toilet in a basement is not the same job as putting one in any other room of the house. In most homes the main sewer line leaves through the foundation at or above the basement floor, which means a toilet sitting on that floor has no downhill path for gravity to do its work. Waste has to be lifted up to the level of the sewer before it can drain away. That single physical reality drives every decision on this page, and it is the reason a basement toilet that works perfectly in someone else's home might be completely wrong for yours.

There are two ways to solve the problem. The first is an upflush or macerating toilet, which sits on top of the finished floor and uses a small grinding pump, hidden behind or beside the bowl, to liquefy waste and push it up through a narrow pipe to the sewer. The second is a standard gravity toilet, which works only if the home already has a below-floor drain rough-in or a sewage ejector pit with a pump in the basement floor. Both approaches are valid, and the better one for you depends entirely on what is already under your concrete. We cover the best models in each category below so you can match the toilet to your plumbing rather than the other way around.

We do not physically test toilets or run them in a lab. Instead we compare published manufacturer specifications, independent MaP (Maximum Performance) flush-test scores where they exist, gallons-per-flush figures, EPA WaterSense certification, macerator and pump horsepower, vertical and horizontal pumping range, and the consistent themes that appear across large numbers of verified owner reviews. For a basement toilet the questions that matter most are these: can it move waste to where your sewer line is, how reliable is the pump or flush over years of use, how loud is it, how easy is it to service, and does it use water efficiently. The picks below answer those questions across a range of budgets, plumbing situations and styles.

How we research and rank toilets for basements

Every model on this list had to fit a real basement plumbing situation and back it up with verifiable specifications. For upflush systems we prioritized macerator power, the rated vertical lift and horizontal run, pump reliability across long-term owner reports, and how easy the unit is to access and service when something eventually wears. For standard gravity picks we prioritized models that score 800 to 1000 grams on the MaP test, because a basement bathroom that drains into an ejector pit still benefits from a strong, complete one-flush clear. We then looked at water efficiency in gallons per flush, EPA WaterSense certification, trapway design, noise, and brand parts availability. We weighted published specifications and aggregated owner reviews over marketing language, and we do not take payment for placement.

The 8 best toilets for basements, reviewed

1

Best Upflush Overall

Saniflo SaniPlus

4.6 No below-floor drain

The SaniPlus is the upflush system we point most basement owners toward because it is the most proven, most widely supported macerating unit in North America and it solves the below-grade problem without breaking a single inch of concrete.

Flush TypeMacerating pump

GPF1.28

Pump Range15 ft up, 150 ft over

Bowl HeightStandard

Warranty2-year limited

Best For

• Basements with no below-floor drain
• Adding a bath where breaking concrete is impractical
• Connecting a sink and shower to the same unit

Not Ideal For

• Buyers who want a silent flush
• Homes that already have an ejector pit

The SaniPlus uses a sealed macerating pump that sits behind the bowl and activates the moment you flush, grinding waste into a slurry and pushing it up through a narrow 1 inch discharge pipe. Its rated 15 feet of vertical lift and 150 feet of horizontal run cover almost any basement layout, and the unit can also accept gray water from a nearby sink, shower or tub, which lets you build a full bathroom without a gravity drain.

Owner reviews over years of use describe it as dependable as long as you treat it correctly, which mainly means flushing only waste and septic-safe paper. The macerator runs for a few seconds on each flush, so it is audible, and the pump is the part that eventually wears, but Saniflo's parts and service network is the broadest in the category, which is exactly why it sits at the top of this list.

Expert Take

If you are finishing a basement bathroom and the sewer line is above your floor, the SaniPlus is the default choice. Buy it knowing two things: never flush wipes, paper towels or feminine products, because the macerator is the one part that fails when abused, and keep the access panel reachable so servicing the pump is a 30 minute job rather than a demolition project.

Check price on Amazon

Bottom Line: The most proven upflush system for basements with no below-floor drain, with the widest parts and service support of any macerating brand.

Most Serviceable

Saniflo SaniAccess 3

4.5 Easy pump access

The SaniAccess 3 is the SaniPlus upgraded for people who want to service the pump without removing the toilet, adding removable access covers that make maintenance far less painful.

Flush TypeMacerating pump

GPF1.28

Pump Range15 ft up, 150 ft over

Bowl HeightStandard

Warranty2-year limited

Best For

• DIYers who want to maintain the unit themselves
• Connecting a half or full bath below grade
• Owners who value long-term access

Not Ideal For

• Buyers chasing the absolute lowest price
• Homes with a gravity drain already in place

Mechanically the SaniAccess 3 matches the SaniPlus, with the same 15 feet of vertical lift and 150 feet of horizontal range, but it adds two removable access panels on the macerator housing. That sounds minor until something clogs the pump: with the SaniAccess you pop a cover and clear it, where on a sealed unit you may have to disconnect the whole assembly. For a basement bath you plan to keep for years, that access is genuinely valuable.

It can also tie in additional fixtures like a sink and shower, so it supports a complete below-grade bathroom. Owners praise the serviceability and the same broad Saniflo parts network, and the usual rule applies: flush only waste and dissolvable paper to keep the macerator healthy.

Expert Take

Spend a little more on the SaniAccess 3 over the SaniPlus if you are at all handy. The removable access covers turn an eventual pump clog from a dreaded job into a quick fix, and over the life of a basement bathroom that convenience pays for itself the first time you need it.

Check price on Amazon

Bottom Line: The same proven Saniflo macerator as the SaniPlus, with removable access covers that make servicing the pump dramatically easier.

Best Standard Gravity

TOTO Drake

4.8 Basements with a drain

If your basement already has a below-floor drain rough-in or a sewage ejector pit, skip the macerator entirely and install the Drake, a true 1000 gram MaP gravity toilet that is quieter, cheaper and simpler than any upflush unit.

Flush TypeG-Max siphon jet

GPF1.28

MaP Score1000 g

Bowl HeightComfort (chair)

Warranty1-year limited

Best For

• Basements with an existing drain or ejector pit
• Owners who want a silent, reliable flush
• Cheap, widely available replacement parts

Not Ideal For

• Floors with no below-grade drain path
• Anyone who cannot break concrete to set a flange

The Drake clears the bowl through a wide, fully glazed trapway driven by TOTO's G-Max siphon jet, which is why it posts the top 1000 gram MaP score and rarely clogs. In a basement that drains into an ejector pit, that strong single flush keeps the pit cleaner and reduces the work the ejector pump has to do. At 1.28 gallons per flush it is also EPA WaterSense certified.

Owners describe it as the toilet they forget about because it simply works, and its flappers, fill valves and seats are stocked everywhere and inexpensive. For a basement bathroom where a gravity drain exists, a standard toilet like the Drake is almost always the smarter choice than an upflush system, because there is no pump to maintain, no grinding noise and no special flushing rules.

Expert Take

Do not buy an upflush toilet by default just because the bathroom is in a basement. If a plumber can confirm a below-floor drain or ejector pit, the Drake gives you a silent, 1000 gram flush with no pump to ever fail, at a fraction of the long-term cost of a macerating system. Confirm your drain situation before you spend on a macerator you may not need.

Check price on Amazon

Bottom Line: The best standard gravity pick for any basement that already has a drain or ejector pit, with a top 1000 gram flush and no pump to maintain.

Quietest Upflush

Liberty Pumps Ascent II

4.5 Quieter macerating

The Liberty Pumps Ascent II is a macerating toilet designed to address the two biggest complaints about upflush systems, noise and pump access, with a quieter run cycle and a smart serviceable design.

Flush TypeMacerating pump

GPF1.28

Pump Range20 ft up, 150 ft over

Bowl HeightComfort (chair)

Warranty3-year limited

Best For

• Basements where flush noise is a concern
• Higher vertical lift requirements
• Owners who want comfort height

Not Ideal For

• Bargain shoppers
• Homes with a gravity drain already present

The Ascent II carries a slightly higher rated vertical lift than the Saniflo units at around 20 feet, and owners frequently note its macerator runs quieter, which matters in a finished basement living space where the bathroom may sit near a media room or bedroom. The comfort-height elongated bowl is also more pleasant for adults than the standard-height bowls common on entry upflush units.

Liberty Pumps has a strong reputation in the pump world for durable, well-built sewage and effluent equipment, and that engineering shows in the Ascent II. The usual macerator rules still apply, flush only waste and dissolvable paper, but for buyers who put noise and build quality first, it is a strong alternative to the Saniflo family.

Expert Take

Choose the Ascent II over the Saniflo units when the upflush toilet sits in or near a finished living area and flush noise is a real concern. The quieter cycle, higher lift and comfort-height bowl justify the step up, and Liberty Pumps' pedigree in sewage equipment is reassuring for the one component that does the hard work.

Check price on Amazon

Bottom Line: A quieter, comfort-height upflush toilet with strong build quality, ideal for basements where the bathroom sits near living space.

Best Gravity Value

American Standard Cadet 3

4.3 Budget gravity setups

For a basement that has a below-floor drain and a tight budget, the Cadet 3 delivers a genuine 1000 gram MaP flush and comfort height without the premium price of the top brands.

Flush Type3 in flush valve

GPF1.28

MaP Score1000 g

Bowl HeightRight (comfort)

Warranty10-year limited

Best For

• Budget basement bathrooms with a drain
• Secondary and guest bathrooms
• Owners wanting power without the premium

Not Ideal For

• Floors with no gravity drain
• Buyers wanting premium styling

The Cadet 3 uses a fast-acting 3 inch flush valve and a wide, fully glazed trapway to clear the bowl in one pass at an efficient 1.28 gallons, earning a 1000 gram MaP score. Its EverClean antimicrobial surface resists the stains and odor-causing bacteria that can build up in a damp, less-ventilated basement, which helps the bowl stay fresher between cleanings.

The bowl is a full-size, dependable piece of china, and the long 10-year warranty is reassuring at this position. For a basement bathroom that already drains by gravity and where you want one-flush strength without overspending, it is the value pick that does not feel like a compromise. For more reliable everyday picks, our guide to the best toilets for home covers daily-use gravity models in depth.

Expert Take

The Cadet 3 is the smart-money standard toilet for a basement bathroom that drains by gravity. You get a true 1000 gram flush, comfort height and a stain-resistant surface for far less than the premium models, and the EverClean coating is a real benefit in the damper air a basement often carries.

Check price on Amazon

Bottom Line: The best value standard toilet for basements with a gravity drain, pairing a 1000 gram flush with a stain-resistant surface.

Easiest All-Rounder

Kohler Highline

4.7 Proven gravity flush

The Highline is the no-drama standard pick for a basement with a drain: a comfort-height fixture with Kohler's strong Class Five flush and one of the best parts networks in the country.

Flush TypeClass Five

GPF1.28

MaP Score1000 g

Bowl HeightComfort (chair)

Warranty1-year limited

Best For

• Basements wanting a safe, proven gravity toilet
• Homes that value easy parts and service
• Comfort height plus strong flush power

Not Ideal For

• Floors with no gravity drain
• Buyers wanting a one-piece design

The Class Five flushing system pairs a large 3-1/4 inch flush valve with a wide flush passage to post a near-perfect 1000 gram MaP score, so a single flush clears the bowl. In a basement draining into an ejector pit, that complete clear keeps the pit cleaner and lightens the load on the ejector pump. The comfort-height elongated bowl is easier for adults and sits stable once installed.

Build quality is what you expect from Kohler, with dense china and a planted feel. Like the Drake, replacement parts are everywhere and inexpensive, which keeps a basement toilet serviceable long term. It is a two-piece, so there is a seam to wipe, but that also makes the lighter components easier to carry down basement stairs during installation.

Expert Take

The Highline is the toilet to buy if your basement has a drain and you want a strong, WaterSense-rated flush from a major brand whose parts your local store will always stock. The lighter two-piece design is also genuinely easier to maneuver down a narrow basement stairway than a heavy one-piece.

Check price on Amazon

Bottom Line: A WaterSense-rated, comfort-height gravity all-rounder with a 1000 gram flush and parts you can find anywhere.

Best for Tight Spaces

Saniflo Sanicompact

4.2 Small basement baths

The Sanicompact is a self-contained macerating toilet with the pump built directly into the unit, giving the smallest footprint of any upflush option for a cramped basement corner or half bath.

Flush TypeBuilt-in macerator

GPF1.0 / 1.28 dual

Pump Range9 ft up, 120 ft over

Bowl HeightStandard

Warranty2-year limited

Best For

• Tight basement corners and half baths
• Powder rooms where space is scarce
• Buyers who want a one-piece upflush look

Not Ideal For

• Adding a shower or sink to the same unit
• Long horizontal or tall vertical runs

Because the macerator is integrated into the body rather than hidden in a separate box behind the bowl, the Sanicompact takes up far less room than a SaniPlus, which makes it the pick when space is the limiting factor. Its dual-flush button keeps water use low, an asset on a unit that pumps every flush. The trade-off is a shorter rated range, around 9 feet of lift, and it is intended for the toilet alone rather than a full bathroom group.

Owners value the compact footprint and the cleaner one-piece look, but note it is best matched to a powder room or half bath where a sink can drain separately. For a small below-grade space where you only need a toilet, it is an efficient, space-saving solution.

Expert Take

Use the Sanicompact only where space is genuinely tight and you need a toilet alone, not a full bathroom group. Its integrated macerator and small footprint are the appeal, but if you want to tie in a shower or sink, or you need a long pumping run, step up to the SaniPlus or SaniAccess instead.

Check price on Amazon

Bottom Line: The most space-efficient upflush toilet, best for a tight basement corner or half bath where only a toilet is needed.

Best One-Piece Gravity

Woodbridge T-0001

4.5 Easy-clean style

For a basement with a gravity drain where you want a modern look, the Woodbridge T-0001 brings a skirted one-piece design at a friendly position, with a seamless body that wipes clean fast in a frequently damp space.

Flush TypeSiphon one-piece

GPF1.28

MaP Score800 g

Bowl HeightComfort (chair)

Warranty5-year (1-yr parts)

Best For

• Basements wanting a modern one-piece look
• Owners who value easy cleaning
• Buyers wanting an included soft-close seat

Not Ideal For

• Floors with no gravity drain
• Heavy one-piece units down narrow stairs

The seamless one-piece body has no tank-to-bowl crevice to scrub, and the smooth skirted sides wipe clean in seconds, which is a real advantage in a basement where dust, humidity and infrequent cleaning are common. The siphon flush clears the bowl quietly at an efficient 1.28 gallons per flush, and the included soft-close seat saves a separate purchase.

Its 800 gram MaP score handles normal basement-bathroom loads well, though it is not at the 1000 gram leaders. The one caution is weight: one-piece toilets are heavy, so plan the trip down the basement stairs. For a gravity-drained basement bath where looks and easy cleaning matter, it is strong value.

Expert Take

Pick the T-0001 for a gravity-drained basement bath where you want a clean, modern look with minimal scrubbing. The seamless skirted body is genuinely easier to keep tidy in a dusty basement, just recruit a second person to carry the heavy one-piece down the stairs during installation.

Check price on Amazon

Bottom Line: A seamless, easy-clean one-piece gravity toilet, best for a basement with a drain where looks and low-effort cleaning matter.

How to choose a toilet for a basement

Start with your drain situation. This is the decision that drives everything else. If your main sewer line exits the foundation above the basement floor and there is no below-floor drain or ejector pit, you need an upflush macerating toilet. If a below-floor drain rough-in or a sealed ejector pit already exists, choose a standard gravity toilet. A short inspection or a plumber visit settles this in minutes and prevents buying the wrong category.

For upflush systems, match the pump to your run. Macerating units are rated for a maximum vertical lift and horizontal distance to the sewer connection. Measure how high and how far the waste has to travel and pick a unit that comfortably exceeds both. The Saniflo SaniPlus and SaniAccess 3 handle about 15 feet up and 150 feet over, while the Liberty Pumps Ascent II rates slightly higher lift. Undersizing the pump leads to clogs and strain.

Prioritize serviceability on a macerator. The pump is the one component on an upflush toilet that will eventually need attention. Choose a model with removable access covers, like the SaniAccess 3, and keep the unit physically reachable so a future repair does not require demolishing finished walls. Build the bathroom around access from day one.

For gravity toilets, prioritize a strong MaP score. If you are installing a standard gravity toilet over a drain, the same rules as any bathroom apply: a high MaP score means fewer clogs and double flushes. Aim for 800 to 1000 grams. A complete one-flush clear is especially helpful when draining into an ejector pit, because it keeps the pit cleaner and reduces how hard the ejector pump has to work.

Consider water efficiency and humidity. An EPA WaterSense toilet uses 1.28 gallons per flush or less, which matters for both gravity and upflush picks since a macerator pumps every flush. Basements also tend to be damp, so an antimicrobial surface like American Standard's EverClean helps the bowl resist the staining and odor that humidity encourages. For a deeper look at top picks across bathroom types, see the best toilets of 2026 roundup.

Plan the install and the parts. Basement stairs are narrow and toilets are heavy, especially one-piece models, so factor in getting the fixture down there. For both categories, choose a brand whose parts are easy to find, because a basement toilet is exactly the kind of fixture people neglect until it fails. The TOTO Drake and Kohler Highline lead on parts availability, and Saniflo leads among upflush brands.

Upflush versus standard gravity for basements

An upflush toilet is the right answer when there is genuinely no gravity drain below your basement floor. It installs on top of the finished slab, needs no concrete cutting, and can often tie in a nearby sink or shower, which makes it the practical way to add a full bathroom to a finished basement that was never plumbed for one. The costs are real: the macerator is audible on every flush, parts are pricier than a standard toilet, and the pump imposes strict flushing rules and an eventual repair.

A standard gravity toilet is the better choice whenever the plumbing allows it, meaning a below-floor drain rough-in or a sewage ejector pit is present. It is silent, uses cheap and universal parts, has no pump to fail, and a top model like the Drake or Highline delivers a 1000 gram MaP flush. The catch is that installing one where no drain exists means breaking concrete to set a flange and, often, adding an ejector pit and pump, which is a larger up-front project. For families weighing heavy daily use as well, our guide to the best toilets for large families covers the strongest low-clog gravity models in depth.

What about comfort and accessibility in a basement bath?

Basement bathrooms are often used by guests, older relatives or as a secondary suite, so comfort height is worth prioritizing on a standard toilet. A comfort-height (chair-height) bowl places the seat at roughly 16.5 to 19 inches, which is easier for adults and older users to sit down on and stand up from. Most upflush bowls are standard height, though the Liberty Pumps Ascent II offers a comfort-height option, which is one more reason it stands out among macerating units.

An elongated bowl adds a more supportive seating area and is the more comfortable choice in nearly every situation where space allows. If the basement bath will serve older family members or anyone with mobility concerns, our guide to the best toilets for seniors goes deeper on comfort height, grab-bar planning and safety, all of which apply equally below grade.
