Most people shopping for a contemporary toilet want one simple thing: a flush that clears the bowl in one go, every time, without a plunger sitting in the corner. The second thing they want is a seat height that does not leave their knees aching every morning. This guide covers eleven modern toilets across a wide spread of heights, bowl shapes, and flush systems, so you can match the fixture to the people who actually live in your house — not to a showroom display.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The modern toilet market splits cleanly: one-piece smooth designs that are easy to wipe down, and two-piece units that are lighter to carry upstairs. This guide sorts the differences in height, rough-in, and flush technology so you can pick the right contemporary toilets for your bathroom.
Our Picks at a Glance
How To Choose The Right Contemporary Toilet
A toilet stays in your bathroom for a decade or more, so checking four specs before you order prevents a return trip to the hardware store. Here is what actually matters, in the order you should think about it.
Height: the feature people feel every single day
Seat height is the number one comfort variable. Standard-height toilets measure roughly 15 to 17 inches from the floor to the rim, which suits most average-height adults. Chair-height models sit at 17 to 19 inches and meet ADA standards, which makes a real difference if anyone in your home has trouble standing up from a low seat. Extra-tall designs push the rim to 21 inches — genuinely helpful for tall users and seniors, but potentially too high for shorter family members. Measure the inseam and standing height of everyone who uses the bathroom, not just the room.
Flush technology: MaP score and gallons per flush
The MaP score (Maximum Performance score) measures how many grams of test waste a toilet clears in a single flush. A 1000 gram rating is the top mark, and it tells you the bowl handles heavy loads without a second flush. Alongside that, check the GPF (gallons per flush) figure. Single-flush toilets at 1.28 GPF cover most households. Dual-flush models let you pick a lighter or heavier flush so you only use the water you need.
Rough-in measurement: the make-or-break number
Rough-in is the distance from the finished back wall to the center of the floor drain. Almost every toilet in this category uses a 12 inch rough-in, which fits standard US bathrooms. If your drain sits at a different distance, the toilet simply will not line up. Measure your rough-in with a tape from the back wall to the drain center before ordering.
One-piece or two-piece construction
One-piece toilets fuse the tank and bowl into a single smooth shell with no gap to gather grime, and they tend to look sleeker. The trade-off is weight — a one-piece unit can run well over 100 pounds and usually needs two people to set. Two-piece models ship in separate boxes, are lighter per box, and often cost less, but the joint between tank and bowl needs a careful seal.

In‑Depth Reviews
1. SUPERFLO 21 Inch High Toilet Elongated Extra Tall Toilets
Our pick — over 4.5★ from 150+ verified ratings; the strongest balance of quality and price.
The throne for six-foot-plus households that are tired of kneeling to sit down.
If someone in your home is tall, elderly, or recovering from knee or back trouble, this is the toilet to buy. Its rim sits 21 inches off the floor — five inches higher than a typical standard bowl — so getting up and down takes far less effort. That extra height is not a gimmick: with 35.2 inches of total height and 29.3 inches of depth, it is a genuinely tall fixture that stands out clearly against a compact chair-height design like the Casta Diva, which tops out at 25.39 inches. The elongated bowl adds seating room as well.
What wins people over is how dramatically the height changes daily life for anyone who has struggled with a low seat. Buyers report: “It took a few days to adjust to the height of this toilet, but now we truly appreciate the height.” The same pattern holds for a 6’3″ husband whose previous bolt-on riser had rusted and slid around — this one eliminates the add-on entirely. The single 1.28 GPF flush carries a 1000 gram MaP rating, meaning it clears heavy loads in one go, and the soft-close lid drops quietly instead of slamming. A 12-inch rough-in means it drops into a standard floor bathroom, and the included accessories plus an installation video keep the job approachable. Plan on roughly half an hour if you are handy.
The honest catch: 21 inches is tall, and if you are closer to average height, your feet may dangle. A 6-foot user describes it as “a lil tall for me,” and one owner needed a small stool. The bowl also holds a shallow pool of water, which a few buyers found less than ideal for cleanliness. Neither issue should stop a tall household — it should just stop a short one. For height-chasing buyers, this is the pick that solves the problem outright.
What earns it top spot
- 21 inch rim height removes the need for a bolt-on riser
- 1000 gram MaP score clears waste in a single 1.28 GPF flush
- Soft-close, removable lid for quiet operation and easy cleaning
- 12-inch rough-in fits standard floor bathrooms with minimal fuss
Worth knowing before you buy
- Genuinely too tall for shorter users — feet may not sit flat
- Shallow bowl water pool draws occasional cleanliness comments
Buy it for: a tall or senior household that wants to end the sit-and-stand struggle without bolting on a riser.
skip it if: your household runs average height — a chair-height model will feel far more natural.
2. Simple Project 21 Inch High Tall Toilet for Seniors & Tall Person
Same towering 21-inch stance as the top pick, but a narrower footprint for tighter bathrooms.
This is the extra-tall toilet for the buyer who wants the height without the bulk. At 35 inches tall with a 27.9-inch depth and a 14.3-inch width, it is a slightly slimmer cousin of the SUPERFLO above — its 14.3-inch width against that model’s 14.7 inches means it tucks into a narrower alcove a touch more easily. The 21-inch bowl height delivers the same core benefit: the ergonomics reduce how far you bend when sitting and standing, which is exactly what makes it suitable for older adults and anyone with mobility concerns. It runs on the same formula — a single 1.28 GPF flush backed by a 1000 gram MaP score, plus a soft-close elongated seat.
The height is clearly the headline. That is the aspect that draws the most praise, with buyers pointing to how much easier it makes getting up and down. The functional story holds up too: the flush carries strong marks, and people consistently find it easy to operate. A black finish option is available alongside white, so it can read as a design piece rather than a clinical one — buyers describe the sleek silhouette fitting neatly into its space without demanding extra width. Assembly is straightforward with the included instructions and video, and a two-year warranty with round-the-clock support backs it up.
One caveat worth flagging honestly: a single three-star account describes a weak flush with a low bowl water level, multiple flushes required, and paper clinging to the sides. That is not the common experience — most owners mention the opposite — but it is the recurring note to weigh. The sturdiness category also lands mixed, so handle the tank assembly with care. Push the height as your reason to buy and you will be pleased; buy it purely for flush bragging rights and the top pick serves you better.
Where it shines: the 21-inch bowl height is the most-discussed feature, and it earns that attention — it makes the whole sit-and-stand motion easier without a single add-on part.
The one thing to check: sturdiness feedback is mixed, and an occasional owner finds the flush underwhelming, so treat the plumbing setup as the part that decides your experience.
Reach for this if… you want extra-tall seating in a bathroom where a wide bowl would crowd the room.
Look elsewhere if… flush power on heavy loads is your single biggest priority.
3. Casta Diva Elongated One Piece Toilet with 17″ Comfort Chair Height Seat
A smooth one-piece shell that hides its plumbing and cleans up in seconds.
Compact bathrooms are where this design earns its keep. The one-piece construction fuses the tank and bowl into a single smooth shell with no seam to scrub, and the fully skirting hides the plumbing for a clean look. At 25.39 inches tall it is the shortest fixture in this group — compare that to the 35.2 inches of the SUPERFLO above — which makes it a smart fit under a window or beside a vanity. The 17-inch seat height meets ADA comfort standards, so it eases sitting and standing for adults and seniors without being extreme, and the 12-inch rough-in drops into standard plumbing.
Quality is the thing people rave about — it is the most-praised aspect by a wide margin, with appearance a close second. The dual-flush system gives you a 1.1 GPF light flush for liquids and a 1.6 GPF full flush for solids, meeting EPA WaterSense criteria, and the flush carries a 1000 gram MaP rating. What makes this one easy to own is how little upkeep it needs: the smooth exterior wipes down fast, the soft-close seat drops quietly, and the seat itself releases quickly for deeper cleaning. It also ships with the wax seal and hardware, so you are not chasing missing parts mid-install.
Here is the trade-off to plan around. The install can be fiddlier than a standard two-piece because the space behind the tank is tight — one owner needed a compact quarter-turn shut-off valve to make everything fit. Measure the gap behind your toilet before you start. Everything else about this unit is designed to reduce long-term hassle, from the no-leak integrated tank to the easy-clean skirt, which is exactly why it holds up as the small-bathroom specialist here.
Why it holds up
- One-piece skirted shell with no seam to scrub and no exposed plumbing
- 17-inch ADA comfort height eases sitting and standing
- Dual flush 1.1/1.6 GPF cuts water use without losing power
- 1000 gram MaP rating plus included wax seal and hardware
Set-up realities
- Space behind the tank is tight, which can complicate installation
- Short overall height may feel low if you are used to a taller bowl
Best fit: a compact bathroom where a smooth, easy-to-wipe one-piece and a gentle ADA height matter more than towering rise.
Think twice if: you have very little room behind the tank and do not want to swap out your water shut-off valve.
4. DeerValley Compact One-Piece Toilet with Soft-Close Seat
A short-depth bowl that gives back inches in a cramped half bath.
When your bathroom is the size of a closet, front-to-back depth is what decides the layout. This unit runs a shallow 23.5-inch depth, a notably compact footprint that carves out useful floor space where a full-size toilet would crowd the door swing. It is aimed squarely at small bathrooms and half baths, and the 4.6-inch worth of reclaimed room is the kind of gain a tiny powder room feels immediately. The one-piece skirted design hides the plumbing and the fully glazed 2 3/8-inch trapway is built to keep clogs from forming, fed by a 1.28 GPF single siphon flush.
What owners praise most is the build quality, with the compact size a strong second. The appeal is practical: a small footprint that still delivers a normal-size seat, easy exterior cleaning, and a soft-close lid that never slams. The trapezoid reach to the back closet bolts makes installation a bit easier than average, and the surface resists yellowing over time. If you are converting an unused nook into a usable half bath, this is the shape that makes it work.
Keep two honest notes in mind. First, this is a low-sitting toilet — that compact height that suits a small space is the same thing that makes it a poor match for tall users or anyone with bad knees. Second, the flush power earns mixed marks; a handful of owners wish for more force, though many report it clears everyday loads fine over months of daily use. There is also a well-documented caution: drop-in tank cleaning tablets can swell the flush valve gasket and cause continuous running, so skip those and clean the bowl the old-fashioned way. At 23.5 inches deep, it reclaims more floor space than any other pick in this guide.
The space math: that shallow 23.5-inch depth is the entire point, and it is the reason this pick beats full-size bowls in a narrow room.
Honest limitation: the low seat height that helps it disappear into a small space is the same spec that makes it a bad fit for tall users — measure your knees, not just your room.
Choose this when: every inch of floor counts and you are fitting out a half bath, cabin, or tight corner.
Pass on it if: anyone in the house is tall or has trouble rising from a low seat.
5. DeerValley Elongated One Piece Toilet with Efficient Dual Flush 1.1/1.6 GPF
ADA comfort height and a skirted shell for buyers who want the upgrade done right.
Accessibility is the design brief here. The seat sits 17 3/8 inches off the floor, meeting ADA-compliant comfort height for users of all ages and abilities, and the one-piece shape runs 27.95 inches deep, 14.17 inches wide, and 26.77 inches tall. That is a genuine step up in comfort over a bare-bones standard bowl while staying far more reachable than the 21-inch towers at the top of this list. The dual-flush system splits 1.1 GPF for light use and 1.6 GPF for solids, and the ceramic body is fired to resist corrosion and scratches.
Build quality is the loudest theme among owners — 104 separate points of praise land on it — with appearance right behind. It is also the pick that drew over 900 ratings, so the consensus is broad rather than thin. The one-piece skirted shell wipes clean with a pass or two, the slow-close seat removes for cleaning, and the 12-inch rough-in slots into standard plumbing. The high-temperature-fired ceramic is described by owners as sturdy and durable, and the covered bolt holes keep the profile tidy.
Two things to weigh before you commit. First, the flush performance and durability aspects both land mixed in customer feedback, so expectations should be measured rather than sold on a single number — the MaP score here is 800g, which sits below the 1000g units elsewhere in this list. Second, a few owners found the integrated internal mechanisms harder to service than a traditional setup, and one had to reposition the floor water valve for clearance. Clean, comfortable, and easy on the eyes, this is the pick for a buyer who values finish and ADA ergonomics over raw flush force.
The standout: ADA-compliant 17 3/8-inch comfort height plus a skirted one-piece shell — the exact spec combo buyers with mobility concerns should be scanning for.
The caveat to price in: an 800g MaP score trails the 1000g bowls elsewhere here, and the internal mechanism is not the easiest thing to service if it ever acts up.
Made for: anyone who wants ADA comfort height, a smooth skirted look, and a dual-flush water saver in one box.
Not your match if: you need the highest flush score in the list — a 1000g unit serves you better.
6. Ivy One Piece Toilet Dual Vortex Flush in Glossy Black 1.1/1.6 gpf
A glossy black one-piece that treats the bathroom like part of the decor.
If your bathroom is built around tile, contrast, and a deliberate color palette, a plain white bowl undercuts the whole room. This one-piece wears a glossy black finish and hides its floor-mount hardware behind concealed side holes, so the profile reads as a single sculpted form. The dual-flush controls let you pick a light 1.1 GPF flush or a full 1.6 GPF flush, and the elongated bowl adds elbow room. The skirted, fully glazed trapway keeps the plumbing tucked away and helps water move freely.
The look is the draw, and owners back that up strongly — appearance and quality share the top of the feedback. Beyond the finish, people find the flush both complete and quiet, and the one-piece design is simple to wipe clean. The scratch-resistant, non-porous ceramic is meant to shrug off routine wear, and the standard 12-inch rough-in keeps the install familiar for anyone replacing an existing toilet. At a 26.8-inch depth and 28.5-inch height, it stays compact enough for a moderate-size bathroom.
The catch, and it is a real one for some rooms: the low tank means the bowl sits closer to the floor and the valve area gets cramped. One owner noted a taller tank meets the wall valve and had to work around it, and this bowl is not built for tall users. The install experience splits between easy and annoying, and the seat-tightness category is the one place feedback leans negative. None of that should scare off a buyer who is buying this for how it looks — just confirm your valve clearance first.
The headline: a glossy black one-piece with hidden mounting holes — the exact spec that turns a fixture into a design feature.
Check before ordering: the low tank squeezes the valve area and the standard height suits shorter rather than taller users.
For the buyer who wants: a bold black finish and hidden hardware as the visual anchor of a renovated bathroom.
Wave it off if: you are tall, or you have tight plumbing clearance behind the toilet that a low tank will not tolerate.
7. American Standard 2887218.020 H2Option Two-Piece Toilet
A two-piece workhorse built on a name you already trust, with siphon-jet flushing.
Sometimes the safe answer is the smart answer, and this is that toilet. It is a two-piece elongated model from American Standard using H2Option dual-flush technology that runs as low as 0.92 GPF for light flushes and up to 1.28 GPF for heavier ones, making it an Ultra-High Efficiency Toilet that meets EPA WaterSense and MaP PREMIUM criteria. The siphon-jet bowl with PowerWash rim is engineered to scrub the bowl as it flushes, and the 12-inch (rough-in) footprint fits standard floor-mounted installs. At just 70.1 pounds it is the lightest unit on this list — compare that to the 100-plus-pound one-piece designs above, which genuinely changes how many people you need on install day.
Construction quality and easy cleaning are the themes owners keep returning to. The flush modes win praise too: the low-water flush still carries real force, and the two-button design makes choosing your water use simple. The top-mounted buttons need a firm push — closer to two inches of travel — which some find a small quirk and others appreciate as deliberate. Once set, the mechanicals arrive pre-adjusted, so there is no fiddling with the flapper or fill valve from the start. A limited lifetime warranty on the chinaware and a five-year warranty on the mechanical parts add real confidence.
Factor in a few logistic realities. The tank and bowl ship in two boxes, the seat, wax ring, flange bolts, and supply line are sold separately, and the tank can sit as much as four inches off the wall. One buyer in five-foot-eight found it comfortable but noted a five-foot-four partner’s feet did not touch the floor — this is a chair-height unit, so check your measurements. A single one-star report of shipping damage cropped up, but that is a freight issue, not a design one. If you want a proven brand, a 70.1-pound two-piece install, and 0.92 GPF flushes, this is the pick.
Why owners back it
- H2Option dual flush runs 0.92 to 1.28 GPF and meets WaterSense and MaP PREMIUM criteria
- Lightest unit here at 70.1 pounds — easier to carry and set than a one-piece
- Pre-set fill and flush mechanisms require no tweaking after installation
Plan for these
- Seat, wax ring, flange bolts, and supply line are all sold separately
- Tank can leave a gap from the wall of up to several inches
Solid choice for: a buyer who wants a proven name, an easier two-piece install, and a low-weight unit to carry upstairs.
Skip past it if: you want everything in one box — this one expects you to buy the seat and seals yourself.
8. TOTO Drake Two-Piece Elongated 1.6 GPF TORNADO FLUSH Toilet with CEFIONTECT
The flush everyone talks about — a circular rinse that clears the bowl in one go.
If raw flushing performance is what you are chasing, this is the name that keeps coming up. The TORNADO FLUSH spins water around the bowl in a circular pattern to wash the entire surface, while the CEFIONTECT glaze is an ultra-smooth finish that keeps waste from clinging so it wipes away easily. A wide 3-inch flush valve and a siphon-jet bowl push it through at a strong 1.6 GPF — a step more powerful than the 1.28 GPF units elsewhere in this list. It fits a 12-inch rough-in and uses a left-hand trip lever, with a standard height that suits people who would rather not sit so high.
The flush power is clearly the star — it lands second only to overall quality in owner feedback, with the swirl action and one-flush clearing drawing the most praise. Owners describe it as the toilet that just works, year after year, without the plunger. The coating earns its own respect: people note the bowl stays visibly cleaner longer, which means less scrubbing between cleanings. Appearance earns a nod too, and the elongated bowl adds seating room. It installs in about twenty minutes for a confident DIYer, and the two-box packaging is designed to protect the ceramic in transit.
Now the honest part. At 1.6 GPF it uses more water per flush than the high-efficiency units here, so it is not the eco-champion of the group. The flush is also noticeably louder than the quiet low-flow models, which a light-sleeping household should know. And a small number of units arrive cracked in shipping — an occasional packaging miss rather than a design flaw, since the failure rate spans all porcelain shipped by freight. If you want a fixture that simply never loses a flush fight, the Drake is the one to reach for.
The performance case: TORNADO FLUSH plus the CEFIONTECT glaze and the 1.6 GPF system combine to clear heavy loads without a second flush — that is the entire pitch of this model.
Honest trade-off: the extra flush power costs a touch more water and runs louder than the low-flow quiet options around it.
The pick for: someone who has fought a weak-flushing bowl and wants the strongest performer, no compromise.
Look elsewhere if: water conservation and a nearly silent flush sit at the top of your wish list.
9. Chateau One-Piece Elongated Toilet Dual-Flush in Glossy Black 1.1/1.6 gpf
A short, wide statement piece for rooms with shelves or a tile counter above.
This one exists to solve a specific problem: a toilet that has to tuck under something. At 24 inches tall with a 27.6-inch depth and a 16.1-inch width, it is one of the lowest and widest of the one-piece designs here — the dimensions chosen so it fits beneath a shelf or a counter edge without scraping. The glossy black one-piece shell carries the same hidden hardware look as the Ivy above, and the fully glazed elongated trapway keeps water moving to guard against clogs. Dual-flush buttons split the flow between 1.1 GPF and 1.6 GPF, and the standard 12-inch rough-in fits typical bathrooms.
The design is what wins people over, with the timeless modern look drawing the most comments — owners call it a sculpture, and the low profile actually becomes the defining feature when it slides beneath an existing counter. The one-piece construction means fewer parts to fuss with, the seat and lid are pre-installed, and the ceiling-friendly proportions suit compact guest bathrooms where a taller bowl would block a mirror or a shelf.
The honest catch is flush behavior. Dual-flush feedback runs mixed — some owners love the water savings, while a few report having to flush more than once on heavy loads. The low tank is tied to complaints of weak flush pressure, and setting the system up often sends owners to video help since the printed instructions can be thin. A small number of units arrived with chipped tanks or mismatched glazing, and one account described a seat failing after a year. Its 24-inch height and low tank suit a guest bath, but a busy family bathroom needs a taller dual-flush model.
The unique angle: at 24 inches tall it is built to fit under a counter, and the glossy black one-piece shell doubles as the room’s focal point.
Size the compromise: that low tank feeds the mixed flush feedback — fine for a guest bath, less ideal for a household flogging it all day.
Right for: a guest or powder room where a low, sleek bowl must slot under an existing shelf or counter top.
Wrong for: a busy family bathroom that needs heavy-load flush power on the first press every time.
10. WOODBRIDGE One Piece Toilet with Soft Closing Seat, Chair Height
ADA chair height wrapped in a sleek chrome-buttoned package — and heavy enough to prove it.
This is a chair-height toilet that takes accessibility seriously without looking clinical. Per the manufacturer, it meets ADA standards with a 17 to 19-inch floor-to-rim height including the seat, which makes it easier for taller users and anyone who has trouble rising from a low bowl. The one-piece shell is fully skirted with a concealed trapway — no bends or corners to trap dust, and no large mounting holes or plastic caps to undermine the clean look. The chrome-plated top button adds a touch of shine, and the package ships with a wax ring, floor bolts, pre-installed seat, and a special hand wrench for tightening bolts in tight spots.
The look is the headliner here — appearance earns the strongest marks of any aspect, with flush performance right behind it. Owners describe a strong flush that works even with low water pressure and leaves the bowl clean, and many find the smooth, skirted exterior quick to wipe down. The dual-flush system covers both light and heavy use, and the seat’s stainless-steel durable hinge means you can pop the seat off to tighten or clean it after years of service.
Two things to plan around before you buy. First, this is a heavy unit — at 119 pounds it is the heaviest here, and owners consistently say you need two or three people to set it safely. Second, installation earns more negative notes than any other aspect, largely because it is such a heavy lift, and one report describes a slow-close seat failing at eleven months with customer-service friction afterward. Barely fitting into some bathrooms is also mentioned; measure your space. If you want ADA chair height with a concealed trapway and chrome top button, the 119-pound weight is the price.
What buyers celebrate
- ADA chair height (17–19 in with seat) for comfort and accessibility
- Fully concealed trapway leaves no ledges for dust or grime
- Chrome-plated top button and one-piece shell give it a clean, upscale look
Before you commit
- 119 pounds is the heaviest in the group — plan for two to three people to install
- Installation is the most commonly flagged friction point in the feedback
Right pick for: anyone who wants ADA chair height with hidden plumbing and a polished chrome finish to match.
Rethink it if: you are installing single-handed — the 119-pound weight makes this an all-hands job.
11. ELLAI Two Piece Elongated Toilets ADA Chair Comfort Height 17.24″
A two-piece black beauty with ADA height and a left-hand lever for classic installs.
Here is the two-piece alternative for buyers who want the chair-height comfort but prefer a lighter, easier-to-set fixture in glossy black. The 17.24-inch seat height is ADA-compliant, giving the ease of sitting and standing that suits elderly users and anyone with mobility challenges, and the elongated bowl adds elbow room. A single 1.28 GPF flush works with a siphon-jet siphon system, a fully glazed 2-inch trapway, and a 3-inch flush valve to clear the bowl in one shot. It carries a 1000 gram MaP rating and, per the manufacturer, meets WaterSense criteria while using at least 20% less water than standard 1.6 GPF toilets.
The look is the main draw — appearance earns the strongest praise — and owners love that it arrives essentially complete: toilet, seat, flush valve, wax ring, and floor bolts are all in the box. The pre-installed tank components mean most of the internal setup is done before the box is opened. The height and the color also draw their share of positive notes from people who wanted a black fixture with a comfortableseat height. For buyers who want a black two-piece at an accessible height, this is the one to beat.
The trade-offs to know: one owner says the toilet “feels cheap,” though that same buyer admits it works fine, and a separate three-star account had the bowl clog once. At 77 pounds it is lighter than the one-piece units here, which makes it far easier to position with a helper. The chunky dimensions — 28.3 inches deep, 17.2 inches wide, 31 inches tall — mean you should confirm the alcove before ordering, and the included plastic seat is a good candidate to swap for a wooden one if you want a sturdier feel. At 17.24 inches ADA height in glossy black with a 1000g MaP flush, it undercuts the one-piece picks on price.
What it delivers: a 1000g MaP flush backed by a glazed 2-inch trapway and a 3-inch valve — the specs that give it real clearing power at a light 1.28 GPF.
Set expectations: the stock seat is basic and at least one buyer felt the overall build was lighter than envisioned, so upgrade the seat if comfort matters.
Worth grabbing if: you want ADA height in a glossy black two-piece that ships with everything needed to install.
Try a different pick if: you prefer a heftier one-piece build and a seat you will not want to replace.
Understanding the Specs
MaP Flush Score Explained
The MaP score (Maximum Performance score) rates the number of grams of test waste a toilet clears in a single flush. A 1000 gram score is the top of the scale and tells you the bowl will handle heavy loads without a second flush. Several toilets here carry that 1000 gram mark, and one sits at 800 grams. Both are genuinely capable, but if you have ever fought a weak-flushing bowl, the higher score is the one to prioritize.
Rough-In Distance Demystified
Rough-in is the measurement from the finished back wall to the center of the floor drain pipe. Nearly every toilet in this category uses a standard 12-inch rough-in, which fits the majority of US bathrooms. Get this number wrong and the toilet will not seat against the flange. Measure yours before ordering, and if you are unsure, have a plumber confirm it — it is the one measurement that can derail an otherwise easy install.

Should I buy a toilet with the seat included or separately?
Final Thoughts: The Verdict
For most buyers, the contemporary toilets winner is the SUPERFLO 21 Inch High Toilet because its 21-inch rim height solves the sit-and-stand struggle that plagues tall households, backed by a 1000 gram MaP flush and a 12-inch rough-in that fits standard plumbing. If you want the strongest, most reliable flush in the group, grab the TOTO Drake with its TORNADO FLUSH swirl and CEFIONTECT glaze. And for a small bathroom that needs a smooth one-piece with ADA comfort height, the Casta Diva Elongated One-Piece is the one to reach for.
