- The verdict
The best flushing residential toilet for most homes is the TOTO Drake Two-Piece, score 9.3. Its rimless TORNADO FLUSH bowl sends water around the bowl in a circular wash, and a 3 inch flush valve with a siphon jet clears waste in one 1.6 gallon flush.
If you want the top measured flush score and smart features in one unit, the EPLO Smart Toilet Bidet hits 1000 grams on the MaP test. For the lowest water use in a two-piece, the TOTO Entrada runs on 1.28 gallons.
Flushing power comes from how the bowl, valve and trapway work together, not from the gallon number alone. A well-designed 1.28 GPF toilet can clear a bowl that a poorly shaped 1.6 GPF model leaves behind.

The best flushing toilets for home bathrooms
The TOTO Drake is the pick for most families, while each toilet below solves a different problem: saving water, fitting a tight bathroom, or adding comfort features. Read each entry for the need it fits best.
TOTO Drake Two-Piece Toilet, 1.6 GPF: Best overall
- TORNADO FLUSH rimless design
- CEFIONTECT smooth glaze
- 3 inch flush valve with siphon jet
- Universal Height, ADA compliant
- 12 inch rough-in
A rimless TORNADO FLUSH bowl with CEFIONTECT glaze and a wide 3 inch valve gives the strongest all-round package for a family bathroom.
Pros
- Circular TORNADO FLUSH action
- CEFIONTECT glaze resists waste sticking
- 3 inch flush valve and siphon jet
- Universal Height helps sitting and standing
Cons
- Seat sold separately
- Tank and bowl ship as two pieces
The TOTO Drake suits a busy family bathroom where the toilet gets used all day. Its TORNADO FLUSH rimless design has dual nozzles and no rim holes, so water washes the bowl surface from more than one direction.
CEFIONTECT is an ultra-smooth glaze that TOTO says keeps waste from sticking, which cuts how often you need to scrub. The wide 3 inch flush valve and siphon jet handle the rest of the work in one flush.
The bowl measures 28.38 inches deep by 17.19 inches wide and stands 30.13 inches tall, and the set weighs about 94 pounds.
Universal Height puts the seat taller than a standard bowl, and TOTO says the model meets the ADA height rule. That matters in a household with older adults or anyone who finds a low seat hard on the knees.
The elongated bowl adds sitting room over a round front, and the left-hand chrome trip lever suits a standard bathroom layout.
The tank and bowl ship as a two-piece set with the mounting hardware. A seat, wax ring, flange bolts and water supply lines are bought separately.
Choose the Drake for the strongest everyday flush in a standard bathroom. The seat cost and the two-piece install are the price of that performance.
EPLO Smart Toilet Bidet: Best smart flush
- 1000 gram MaP flush score
- Foam Shield splash control
- 1.6 or 1.1 GPF dual flush
- Auto open, close and flush
- 17.41 inch ADA seat height
A bidet toilet with a 1000 gram MaP flush, foam shield and hands-free controls, for buyers who want cleaning and flushing in one unit.
Pros
- 1000 gram MaP flush score
- Foam Shield limits splashback
- Full and half flush options
- Hands-free lid and flush
Cons
- Needs a nearby power outlet
- More electronics to live with than a basic toilet
The EPLO Smart Toilet Bidet suits a buyer who wants washing and flushing handled by one unit. Its 1000 gram MaP score is the top flush figure in this group, and the foam shield lays a barrier that EPLO says limits splashback and keeps the bowl cleaner.
The foam also traps smells and softens the film that builds on the bowl.
A 1.6 gallon full flush and a 1.1 gallon half flush give you a water choice per use. The bowl opens its lid as you approach and flushes as you leave, with a foot sensor for seat and lid control.
EPLO lists a built-in hidden tank, so the flush does not depend on line pressure.
The seat sits at 17.41 inches and meets the ADA height standard. The bidet wash has front, rear and oscillating modes with adjustable pressure, position and temperature, plus a warm air dryer with adjustable temperature and position.
A nightlight and deodorizer round out the comfort list.
The trade-off is power: this toilet needs an outlet near the installation. It also carries more electronics than a plain flush toilet, so it's the wrong pick if you want the simplest possible bathroom fixture.
TOTO Entrada Two-Piece Toilet: Best water-saving flush
- E-Max 1.28 GPF flushing system
- 3 inch flush valve and large trapway
- Universal Height, ADA compliant
- Glazed trapway
- 12 inch rough-in
TOTO's E-Max system pairs a 3 inch valve with an extra-large siphon jet to clear the bowl on 1.28 gallons, the lowest water use among the two-piece picks here.
Pros
- 1.28 GPF E-Max flush
- Large siphon jet and glazed trapway
- Universal Height seating
- Meets WaterSense and CEC rules
Cons
- Seat sold separately
- No CEFIONTECT glaze
The TOTO Entrada suits homes where water bills and environmental rules matter. Its E-Max system uses 1.28 gallons per flush and still pairs a 3 inch flush valve with an extra-large siphon jet and a large trapway.
The narrower tank and elongated bowl keep the profile lower than the Drake, and the body measures 28.63 inches deep by 15.25 inches wide. Universal Height gives the same easier sitting and standing, and the glazed trapway helps waste slide through.
TOTO says the Entrada meets WaterSense and California's CEC and CALGreen standards. Those labels matter if your area limits toilet water use or you're replacing a fixture in a rebate program.
The flush relies on gravity and siphon action rather than pressure assist, so it runs quiet without extra moving parts.
The Entrada skips the CEFIONTECT glaze, so expect to clean the bowl a little more often than on the Drake. The seat also comes separately.
Pick the Entrada for the best water-saving flush in a two-piece toilet. Step up to the Drake when the smoother glaze and circular wash are worth more to you.
St. Tropez Comfort Height One-Piece Toilet: Best one-piece design
- Dual Vortex 1.1/1.6 GPF flush
- Comfort height seat
- One-piece skirted body
- Scratch-resistant ceramic
- 12 inch rough-in
A one-piece toilet with a cyclonic dual flush and a taller seat, for buyers who want an easier bowl to wipe down and less water on light flushes.
Pros
- Cyclonic Vortex rinse
- 1.1 GPF half flush
- One-piece body with no tank seam
- Scratch-resistant non-porous ceramic
Cons
- Heavier than a two-piece at 109 lb
- Costs more than basic two-piece models
The Swiss Madison St. Tropez suits a bathroom where you want the bowl to look built in and wipe down fast.
Its one-piece body joins the tank and bowl with no seam, and the Vortex dual flush creates a cyclonic rinse that scrubs the bowl walls.
The 1.1 gallon half flush covers liquid waste and the 1.6 gallon full flush handles solids. The ceramic is non-porous and scratch resistant, so daily cleaning is a wipe rather than a scrub.
The bowl measures 27 inches deep by 15.12 inches wide and stands 31.18 inches tall.
Comfort height raises the seat for easier use, and the elongated bowl adds room. The full set includes the seat, wax ring, bolt kit and flush valve.
The white hardware matches the glossy white body.
A one-piece toilet weighs more than a two-piece set, about 109 pounds here, and costs more to buy. Moving it into place is a two-person job.
Our Swiss Madison St. Tropez review covers the fit and finish in more detail.
DeerValley Elongated One-Piece Dual-Flush Toilet: Best for tight bathrooms
- Dual flush 1.1/1.6 GPF
- 800 gram MaP score
- Skirted one-piece body
- Standard 16 7/8 inch seat height
- 12 inch rough-in
A slim skirted one-piece with a dual flush and a glazed self-cleaning surface, sized for bathrooms where every inch of floor counts.
Pros
- Narrow 14 inch width
- Dual flush saves water
- Skirted body hides the trapway
- Quick-release seat for cleaning
Cons
- 800 gram MaP score sits below the top picks
- Standard height rather than comfort height
The DeerValley one-piece suits a small bathroom where floor space is tight. Its 14 inch width is the narrowest body in this roundup, and the skirted design hides the trapway so there are no ledges to collect dust.
The full body measures 28.15 inches deep by 14.17 inches wide.
The dual flush runs 1.1 gallons for liquids and 1.6 for solids, and the glazed self-cleaning surface helps waste slide away. DeerValley rates the flush at 800 grams on the MaP test.
The seat sits at a standard 16 7/8 inches and closes slowly.
That score is lower than the 1000 gram toilets here, so a heavy load may need more help than on the top picks. The seat height is standard, not comfort height, so taller users should look at the Casta Diva or EPLO instead.
The seat lifts off for cleaning, and the 12 inch rough-in fits a standard replacement. The high-temperature ceramic resists scratches and corrosion over routine use.
Choose DeerValley for a slim one-piece in a tight room, not for the strongest flush score in the group.
Casta Diva 17-Inch Chair Height One-Piece Toilet: Best for easy sitting and standing
- 17 inch ADA comfort seat height
- 1000 gram MaP siphon flush
- Dual flush 1.1/1.6 GPF
- Soft-close quick-release seat
- 12 inch rough-in
A compact one-piece with a 1000 gram MaP score and a 17 inch seat, aimed at taller users and anyone who finds a low bowl hard on the knees.
Pros
- 1000 gram MaP flush score
- 17 inch comfort height seat
- Soft-close seat lifts off for cleaning
- Includes wax seal and mounting kit
Cons
- Compact bowl leaves less sitting room
- One-piece body is heavy to move alone
The Casta Diva chair height toilet suits taller users and anyone who wants an easier seat to stand up from. Its 17 inch seat meets the ADA comfort height standard, and the bowl still measures only 27.17 inches deep and 14.37 inches wide.
The siphon jet flush carries a 1000 gram MaP score with a fully glazed trapway, so it clears waste quietly without clogging. The dual flush offers 1.1 gallons for liquids and 1.6 for solids and meets WaterSense criteria.
The flush valve and fill valve come pre-installed in the tank.
The skirted one-piece body has no tank seam, which removes a common leak point. The soft-close seat closes without a slam and lifts off for cleaning, and the box includes the wax seal and mounting kit.
The seat height is the standout spec for anyone with knee or back strain.
The compact footprint means less sitting room than a longer elongated bowl elsewhere in this group. Pick Casta Diva when seat height matters most, and accept the tighter bowl in return.
Loupusuo Luxury Smart Toilet with Heated Seat: Best for cold bathrooms
- Heated seat and warm water wash
- Anti-splash foam on sitting
- Siphon flushing system
- Smart foot sensor
- 12 inch rough-in
A smart toilet with a heated seat, warm water washing and anti-splash foam, for anyone who wants comfort and cleaning without a separate bidet seat.
Pros
- Heated seat for winter
- Warm water wash with filtration
- Anti-splash foam layer
- Hands-free foot sensor
Cons
- Requires a power outlet near the toilet
- More features to maintain than a basic flush toilet
The Loupusuo smart toilet suits a cold bathroom or a buyer who wants comfort features without adding a separate bidet seat. Its heated seat and warm water wash make winter trips easier, and the water runs through a built-in filtration system.
The seat has a gourd shape sized for adults and children alike.
Anti-splash foam rises when you sit, and the foot sensor opens the lid without a hand touch. A siphon flushing system clears the bowl, and the model adds starlight ambient lighting and a large LED display showing Fahrenheit temperature.
An atomized fragrance system keeps the air fresh.
The model needs a power outlet near the toilet, so check the outlet and rough-in before ordering. That's the main planning cost, and it also means more parts to maintain than a basic two-piece toilet.
The body weighs about 88 pounds.
A smart toilet like this belongs in a main bathroom or a primary suite rather than a rarely used powder room. Choose Loupusuo for warmth and hands-free use, and the EPLO if the flush score is your first concern.
Gerber Maxwell Crest Elongated Two-Piece Toilet: Best for clog-prone households
- 1.28 GPF power flush
- Fluidmaster 400A fill and 3 inch flush valves
- Glazed trapway
- Soft-close seat included
- Wax ring and mounting kit included
A two-piece toilet built around a glazed trapway and a 1.28 gallon flush, with the seat and wax ring in the box for a simpler install day.
Pros
- Glazed trapway for smooth waste flow
- 1.28 GPF high-efficiency flush
- Soft-close seat included
- Wax ring and hardware in the box
Cons
- No dual flush option
- Standard height seat
The Gerber Maxwell Crest suits a household that has fought clogs before. Its glazed trapway keeps waste flowing, and Gerber pairs a Fluidmaster 400A fill valve with a 3 inch flush valve for a 1.28 gallon flush that Gerber says clears the bowl with ease.
The two-piece set arrives with the soft-close seat, wax ring and mounting hardware in the box. That removes the extra shopping trip most two-piece installs need.
The bowl measures 28.5 inches deep by 17.13 inches wide and stands 31 inches tall, and the set weighs about 79 pounds.
The elongated bowl gives sitting room and the seat lowers without a slam. Gerber describes the flush as quiet and water-saving, with no dual-flush option to choose from.
The design is aimed at busy households that want one-and-done flush reliability.
Gerber describes the Maxwell Crest as an ADA-compliant design. Read our Gerber Maxwell Crest two-piece review for the install details.
Pick it for clog-prone homes and an all-in-one install kit.
WOODBRIDGEE One Piece Toilet with Soft Closing: Best for quiet flushes
- 1000 gram MaP flush score
- Siphon flushing, fully glazed
- Chair height design
- Soft-close seat
- Wax ring and bolts included
A chair height one-piece with a 1000 gram MaP score and a siphon flush, sold with the seat, wax ring and bolts in one package.
Pros
- 1000 gram MaP flush score
- Quiet siphon action
- Chair height for taller users
- Concealed trapway with no dust corners
Cons
- Rectangular seat shape differs from oval bowls
- Heavier one-piece body at install time
The WOODBRIDGEE one-piece suits a taller household that wants a quiet flush. Its chair height seat measures 17 to 19 inches from floor to rim, meeting the ADA standard and easing the sit-down and stand-up motion.
The bowl measures 28.5 inches deep by 14.5 inches wide.
The siphon flush is fully glazed and carries a 1000 gram MaP score, so it clears a full test load without clogs. WOODBRIDGEE says the bowl runs quiet, which matters in a bathroom next to a bedroom.
The concealed trapway leaves no bends or corners to gather dust, and there are no mounting holes or plastic caps on show.
The seat has a soft-close hinge in stainless steel and lifts off for cleaning. The box includes the wax ring, floor bolts and a hand wrench for tightening in tight spots.
The product meets US UPC and Canada CSA standards and carries WaterSense certification.
The rectangular seat shape differs from the oval bowls most buyers expect, so measure your space and sightlines first. The one-piece body is also heavy to lift into place.
Choose it for a quiet, strong flush at chair height.
How these flushing toilets compare
The comparison table puts the flush system, MaP score and rough-in for each toilet side by side. Use it to spot the models that clear the most waste per flush, then read the write-ups for the fit details.
| Product | Best for | Flush system | Bowl | Rough-in | Our score |

| WOODBRIDGEE One Piece Toilet with Soft Closing | quiet flushes | Siphon, 1.28 GPF dual | 8.2 |
Two-piece models like the TOTO Drake and Entrada are lighter to move and easier to fit in a standard bathroom. One-piece models like the St.
Tropez and Casta Diva hide the trapway and remove the tank seam, at the cost of more weight and a higher price. The weight gap is real: the Drake set is about 94 pounds, while the St.
Tropez and Casta Diva one-piece bodies run heavier.
Flush design matters more than tank size. A rimless TORNADO FLUSH bowl, a dual-nozzle Vortex wash or a siphon jet all change how water reaches the bowl surface, and each one can clear waste on 1.28 gallons or less.
A dual-flush model also lets you drop to 1.1 gallons on light use, which a single-flush 1.28 or 1.6 gallon model cannot do.
What comes in the box splits the group too. The Gerber Maxwell Crest, WOODBRIDGE and Casta Diva include the seat and wax ring.
The TOTO Drake and Entrada ship as bowl and tank only and need a seat, wax ring, flange bolts and supply lines bought separately.
How we compared these toilets
We compared flush system designs, MaP scores, water use, bowl and seat dimensions, rough-in size and what each box includes. Our score weighs those specs and features against what a home buyer wants from a strong flush.
The facts come from the product data each brand publishes, and the scoring favors toilets that clear waste in one flush without extra cleaning or water waste.
Weight and dimensions feed in too, because a toilet that is hard to move or too wide for the room is a harder install.
TOTO's TORNADO FLUSH and E-Max systems rank high because the maker pairs a wide valve with a shaped bowl rather than relying on water volume. Dual-flush models score well when they offer a real water saving without dropping the MaP score.
A low MaP score pulls a model down even when its other features are strong.
Which flush system clears a bowl best?
A rimless or dual-nozzle bowl that washes the whole surface clears waste better than a plain rim with holes. The water pattern does more work than the gallon count.
TORNADO FLUSH in the TOTO Drake uses dual nozzles and a rimless design to send water in a circular wash. Vortex in the St.
Tropez creates a cyclonic rinse. A siphon jet in the Entrada and Casta Diva pulls waste through a large trapway.
A MaP score gives you a measured comparison. A 1000 gram score means the toilet cleared the full test load in one flush.
An 800 gram score like the DeerValley's means a smaller load. Three toilets here carry the 1000 gram MaP score: the EPLO, Casta Diva and WOODBRIDGE.
What does a 1.28 GPF toilet mean for flushing?
It means the toilet uses 1.28 gallons per flush instead of 1.6. The TOTO Entrada and Gerber Maxwell Crest both meet that figure, and TOTO pairs its E-Max system with a 3 inch valve to keep the flush strong.
Does a wider flush valve matter?
Yes. A 3 inch valve releases water faster than a 2 inch valve.
The TOTO Drake and Entrada both use a 3 inch valve with a siphon jet, and Gerber pairs its 3 inch flush valve with a Fluidmaster fill valve. Faster water release is what lets a low gallon count still clear the bowl.
Should you pick a two-piece or one-piece toilet?
Pick a two-piece if you want a lighter install and a lower price. Pick a one-piece if you want a hidden trapway and no tank seam to leak or collect dust.
A two-piece toilet ships as a separate tank and bowl. That makes it lighter to carry up stairs and easier to replace if one part cracks.
TOTO's Drake and Entrada, plus the Gerber Maxwell Crest, follow this design. The Drake set is about 94 pounds and the Gerber about 79 pounds.
A one-piece toilet joins the tank and bowl in a single ceramic shell. The skirted body on the St.
Tropez, DeerValley and Casta Diva hides the trapway and leaves a smooth surface to wipe. That's easier to clean but heavier to move and more expensive to buy.
The St. Tropez body is about 109 pounds and the Casta Diva more than that.
Is a two-piece toilet easier to install?
It usually is. A two-piece set is lighter and the tank goes on after the bowl is set.
The Gerber Maxwell Crest includes the seat, wax ring and mounting hardware, so most of the install kit arrives in one box. The TOTO two-piece models need those parts bought separately.
How much water should a strong-flushing toilet use?
Aim for 1.28 gallons per flush or less for the best balance of water saving and clearing power. Dual-flush toilets that offer 1.1 gallons for liquids save more without losing the strong full flush.
The TOTO Entrada and Gerber Maxwell Crest run at 1.28 gallons. The TOTO Drake uses 1.6 gallons and pairs that with CEFIONTECT to reduce how often you clean the bowl.
The EPLO, St. Tropez, DeerValley and Casta Diva all offer a 1.1 gallon half flush for liquid waste.
Water use is only one part of the picture. A 1.1 gallon flush on a bowl with a weak rinse pattern can leave more waste behind than a 1.6 gallon flush on a well-shaped bowl.
The MaP score tells you which one actually clears. That's why the TOTO Drake still ranks first despite using as much water as the 1.6 GPF models.
Do dual-flush toilets really save water?
They can, when the people in the house use the half flush for liquids. A 1.1 gallon half flush against a 1.6 gallon full flush saves about a third of the water on each light use.
That adds up in a busy family bathroom over a year. The catch is habit: a household that only ever presses the full flush gets no saving at all.
What rough-in and seat height should you plan for?
Check two numbers before you order: your rough-in distance and your preferred seat height. A 12 inch rough-in fits all the toilets here, and a comfort height seat sits around 17 inches.
Rough-in is the distance from the finished back wall to the center of the floor drain. Every toilet in this roundup is designed for 12 inches.
If your bathroom measures 10 or 14 inches, you'll need a different model. Measure from the finished wall, not the bare studs.
Seat height changes how the toilet feels. Standard height sits near 15 to 16 inches.
Comfort height and ADA models sit at 17 inches or more. The Casta Diva at 17 inches, the EPLO at 17.41 inches and the WOODBRIDGE at chair height all ease the sit-down motion for taller users and older adults.
The TOTO Drake and Entrada use Universal Height to reach the same comfort zone.
Which seat heights are ADA compliant?
A toilet meets the ADA height rule when the seat sits 17 to 19 inches from the floor with the seat included. The TOTO Drake, Entrada, Casta Diva and WOODBRIDGE all state that their seat height meets or can meet the ADA standard.
Remember that the TOTO models need a seat added before the height counts.
Which toilet fits a small bathroom?
The DeerValley one-piece fits a small bathroom best, at 14 inches wide. The Casta Diva is the next most compact at 14.37 inches wide and 27.17 inches deep.
Narrow and shallow matters in a powder room or a bathroom with the toilet close to a vanity or door. A skirted one-piece body hides the trapway and leaves fewer corners to catch dust.
The DeerValley's 28.15 inch depth also leaves more floor in front than the deeper TOTO bowls.
Check the depth as well as the width. A long elongated bowl needs more room in front for leg clearance.
A compact model like the Casta Diva saves floor space but gives up some sitting room compared with the elongated bowls on the TOTO models. Measure the space in front of the bowl before you commit to a deeper model.
The verdict
The best flushing residential toilet for most homes is the TOTO Drake Two-Piece. Its TORNADO FLUSH bowl, CEFIONTECT glaze and 3 inch valve make it the strongest all-round choice for daily family use.
Pick the EPLO Smart Toilet Bidet if you want a 1000 gram flush plus washing and hands-free controls. Pick the TOTO Entrada if water saving comes first.
For a compact fit, the DeerValley's narrow body wins. Compare the TOTO models in our Drake vs Entrada guide or browse our TOTO toilet comparison to choose your flush system with confidence.

Frequently asked questions
What is the best flushing residential toilet?
The TOTO Drake Two-Piece is the strongest all-round choice, with a TORNADO FLUSH rimless bowl, CEFIONTECT glaze and a 3 inch flush valve. If you want the highest measured flush score, the EPLO Smart Toilet Bidet, Casta Diva and WOODBRIDGEE all reach 1000 grams on the MaP test.
Does a 1.28 GPF toilet flush as well as a 1.6 GPF one?
It can, when the bowl and valve are designed together. TOTO's E-Max system uses a 3 inch flush valve, an extra-large siphon jet and a large trapway to clear the bowl on 1.28 gallons.
Water use alone doesn't predict how well a toilet flushes.
What does a MaP score tell me about a toilet?
The MaP score is the weight of waste a toilet clears in one flush during a standardized test. A score of 1000 grams means it clears the full test load.
The EPLO Smart Toilet Bidet, Casta Diva and WOODBRIDGEE all carry a 1000 gram score.
Are two-piece or one-piece toilets better for flushing?
Both can flush well, because the flush depends on the bowl design and valve rather than the tank count. Two-piece models are lighter to move and cheaper to buy.
One-piece models hide the trapway and have no seam where the tank meets the bowl.
How much rough-in space does a strong-flushing toilet need?
All the toilets here are designed for a standard 12 inch rough-in, which is the distance from the finished back wall to the center of the drain. Measure yours before ordering, because a 10 inch or 14 inch rough-in needs a different model.
Do smart toilets flush as well as standard toilets?
The EPLO Smart Toilet Bidet carries a 1000 gram MaP flush score, matching the best standard toilets here. The Loupusuo uses a siphon flushing system.
A smart model adds a power outlet requirement on top of the flush design.
