American Standard offers lower-volume flush options in a two-piece design, while the compact HOROW and WinZo picks address tighter rooms.

The best dual flush toilets for daily use
The DeerValley Elongated One-Piece Dual-Flush Toilet leads this roundup, followed by the American Standard H2Option and HOROW HR-ST076WD. The seven picks below cover standard and compact footprints, two-piece and one-piece builds, and different seat heights.
DeerValley Elongated One-Piece Dual-Flush Toilet: Best for everyday households
- 1.1/1.6 GPF dual flush
- Elongated bowl
- Skirted design
- 12 in rough-in
Two flush choices pair with an elongated bowl and skirted exterior. Its 12 in rough-in is a useful starting point for standard replacements, but measure before buying.
Pros
- Two flush choices
- Skirted exterior
- Removable seat
Cons
- Standard seating height
- Requires a 12 in rough-in
The DeerValley Elongated One-Piece Dual-Flush Toilet combines 1.1/1.6 GPF flush options with an elongated bowl and skirted exterior. It has a 12 in rough-in, a standard seat height of 16 7/8 in and a removable seat.
Choose it for a familiar, elongated shape with two flush volumes and a smooth outside profile. Skip it if you need chair-height seating or your rough-in is not 12 in.
American Standard H2Option Two-Piece Toilet: Best for two-piece fans
- 0.92/1.28 GPF dual flush
- Elongated front
- Siphon jet bowl
- Seat sold separately
A two-piece toilet with lower flush volumes and an elongated front. The toilet seat is sold separately, so include that in your installation plan.
Pros
- Two flush options
- Siphon jet bowl technology
- Lifetime chinaware warranty
Cons
- Seat sold separately
- Standard height
The American Standard H2Option Two-Piece Toilet offers 0.92/1.28 GPF flush settings, an elongated front and siphon jet bowl technology. Its seat is sold separately, so plan for a compatible seat when replacing a toilet.
Choose this model if you want a two-piece layout and the lower flush-volume choices suit your priorities. Skip it if you want a toilet with a seat included or a one-piece exterior that is easier to wipe around.
HOROW HR-ST076WD Compact One-Piece Toilet: Best for compact comfort
- 1.1/1.6 GPF dual flush
- 28.75 in depth
- Chair-height seating
- Skirted sides
A compact footprint, elongated bowl and chair-height seating suit smaller bathrooms where sitting height also matters. HOROW specifies a 12 in rough-in.
Pros
- Compact depth
- Chair-height seating
- Soft-close seat included
Cons
- Confirm bathroom clearance
- Professional installation is recommended
The HOROW HR-ST076WD Compact One-Piece Toilet has a 28.75 in depth, 14 in width and 28 in height, with an elongated bowl and chair-height seating. Its dual flush uses 1.1 GPF for liquid waste and 1.6 GPF for solid waste.
The skirted design covers much of the exterior trapway, and the removable soft-close seat is included. Choose it for a smaller bathroom where chair-height seating matters, and skip it if the measured space cannot accommodate its full dimensions.
Woodbridge Dual-Flush One-Piece Toilet: Best for raised seating
- Dual flush
- Chair-height seating
- Skirted trapway
- Soft-closing seat
Chair-height seating and a skirted trapway give this one-piece toilet a practical mix of access and simpler exterior cleaning. Its listed overall height is 22 in, so verify dimensions with the seller before ordering.
Pros
- Chair-height seating
- Soft-closing seat included
- Skirted trapway
Cons
- Overall height detail needs confirmation
- One-year limited warranty
The Woodbridge Dual-Flush One-Piece Toilet has chair-height seating, a skirted trapway and an included soft-closing seat. The brand describes its siphon flush as quiet and says the toilet is WaterSense certified.
Its dimensions are 28.5 in deep, 14.5 in wide and 22 in high. Choose it for chair-height seating and a skirted one-piece form, but confirm the dimensions before ordering because the stated overall height is unusual compared with the other models here.
WinZo Compact One-Piece Toilet: Best for tiny bathrooms
- 0.8/1.6 GPF dual flush
- 22.8 in projection
- 12 in rough-in
- Round shape
Its short projection is the main reason to consider it for a tiny bathroom or powder room. The round shape and 16 in seat height may suit some users better than an elongated, taller model.
Pros
- Short projection
- Two flush options
- Soft-close seat included
Cons
- Does not fit a 10 in rough-in
- Standard seat height may not suit taller users
The WinZo Compact One-Piece Toilet is 23 in deep and has a round bowl, 0.8/1.6 GPF flush options and a 16 in seat height. Its rough-in is 12 in, and it does not fit a 10 in rough-in.
Choose it when every inch of front-to-back space matters and a round bowl works for your household. Skip it if you prefer an elongated bowl or need a taller seat.
DeerValley Symmetry Dual-Flush One-Piece Toilet: Best for short elongated bowls
- 1.1/1.6 GPF dual flush
- Elongated seat
- Skirted trap
- Quick-release soft-close seat
An elongated seat and compact dimensions make this a candidate for a smaller bathroom. It has a quick-release seat and dual flush settings of 1.1 and 1.6 GPF.
Pros
- Compact dimensions
- Two flush options
- Quick-release soft-close seat
Cons
- Confirm rough-in and clearance
- Standard seat height
The DeerValley Symmetry Dual-Flush One-Piece Toilet has an elongated seat, a skirted trap and quick-release soft-close seat. Its dimensions are 26.77 in deep, 17 in wide and 27.01 in high, and its dual flush uses 1.1 and 1.6 GPF.
The maximum flushing performance is 1,000 g, and the package includes installation instructions, floor bolts, a wax ring and a toilet seat. Choose it for a shorter elongated option, but measure the 17 in width carefully where side clearance is limited.
HOROW T0307W Compact One-Piece Toilet: Best for narrow floor plans
- 1.1/1.6 GPF dual flush
- 23.62 in depth
- Elongated seat
- 12 in rough-in
The short depth and elongated seat target bathrooms where floor space is tight. Check its 15.75 in width against the available side clearance.
Pros
- Short depth
- Two flush options
- Soft-close seat included
Cons
- Wider than some compact models
- Confirm the 12 in rough-in
The HOROW T0307W Compact One-Piece Toilet has a depth of 23.62 in, a width of 15.75 in and a height of 25.98 in. It has an elongated seat, 1.1/1.6 GPF flush options and is designed for a 12 in rough-in.
The skirted exterior covers the trapway, and the included seat closes softly. Choose it for a compact floor plan that still calls for an elongated seat, and skip it if its width crowds the vanity or wall.
How to choose the best dual flush toilet for your bathroom
Choose the best dual flush toilet by checking fit first, then seat height, bowl shape and flush controls. A water-saving setting has little value if the toilet blocks a door, feels uncomfortable or does not match the existing rough-in.
Measure from the finished wall to the center of the floor bolts to find the rough-in. Measure the available depth and width as well, including space for the door, vanity, knees and nearby fixtures.
Most models here specify a 12 in rough-in. WinZo specifically does not fit a 10 in rough-in, so don't assume a compact body can solve a rough-in mismatch.
Next, decide whether an elongated or round bowl makes more sense. An elongated bowl provides more sitting room, while a round bowl can work better where projection is the main constraint.
The WinZo is the shortest option in this group, with a 23 in stated depth and round shape. For a compact room where an elongated seat matters, compare the HOROW T0307W and DeerValley Symmetry dimensions against the actual floor area.
Seat height is another daily-use choice. Standard-height models suit buyers who prefer a lower seat, while chair-height designs can make sitting and standing easier for many adults.
The HOROW HR-ST076WD and Woodbridge picks offer chair-height seating. If height is a deciding factor, read chair height versus standard toilet height before you choose.
Then compare the two flush volumes and how the controls are used. A lower-volume flush is intended for suitable lighter waste, while the fuller option handles the other flush need, according to each model's instructions.
What do the flush numbers mean on dual flush toilets?
The numbers show how many gallons each flush uses. For example, 1.1/1.6 GPF indicates a lower-volume and a higher-volume choice, while WinZo's 0.8/1.6 GPF offers a wider difference between its two settings.
American Standard H2Option uses 0.92/1.28 GPF, the lowest pair among these options. DeerValley, HOROW and several other picks use 1.1/1.6 GPF.
Lower gallons per flush can reduce water use when the lighter setting is chosen for appropriate waste. Your actual use depends on how often each setting is selected and how many people share the bathroom.
Don't pick on the smallest number alone. The flush setting, bowl design and installation all matter for daily use, so choose a model whose instructions and controls are easy for everyone in the home to follow.
Which dual flush setup suits your household?
A dual flush toilet is easiest to use when everyone understands which control to press. Before installation, read the instructions and make sure the buttons are clearly associated with the lighter and fuller flush.
For a shared bathroom, explain the two choices to household members and guests. This reduces guesswork and helps the toilet deliver the water use you expect from its two settings.
During installation, confirm the rough-in, floor condition, water supply connection and clearance before moving the toilet into place. Several models include a wax ring, floor bolts and instructions, but included parts vary.
The HOROW HR-ST076WD recommends professional installation. If the existing toilet is difficult to remove, the floor bolts are damaged or the supply connection needs changes, bring in a plumber rather than forcing the fit.
Once installed, check that the toilet sits level and that the base does not rock. Follow the manufacturer instructions for connecting the supply, setting the flush valve and checking for leaks.
What care keeps a dual flush toilet working well?
Use routine bathroom cleaning and follow the care instructions for the specific toilet. A skirted exterior can reduce exposed grooves around the base, but the bowl, seat, hinges and floor still need regular attention.
Quick-release seats, where included, can make it easier to reach the area around the hinges. Remove the seat according to its instructions, clean the exposed surfaces, then secure it back in place.
Avoid harsh cleaning tools or chemicals unless the manufacturer permits them. Abrasive products can scratch surfaces, and unsuitable chemicals can damage components.
If a flush becomes weak or the tank keeps refilling, check the owner's instructions before changing internal parts. Keep the toilet's model details and installation instructions somewhere accessible for future maintenance.
Common mistakes when buying a dual flush toilet
The most common buying mistake is ordering by product label instead of measuring the existing bathroom. A "compact" toilet can still be too wide, too deep or incompatible with the rough-in.
A second mistake is overlooking what comes in the box. American Standard H2Option is sold without a seat, while the other picks describe included seats, so account for that difference before scheduling installation.
Don't treat bowl shape and seat height as minor details. The WinZo round bowl and 16 in seat may fit a small room, but some people will prefer the extra sitting room or taller seat of another model.
Finally, don't assume all two-button systems work the same way. Learn the controls for the model you choose, and use the setting assigned to each flush type in its instructions.

Which best dual flush toilet should you choose?
Choose the DeerValley Elongated One-Piece Dual-Flush Toilet for a balanced daily-use option with an elongated bowl, skirted exterior and two flush volumes. Pick American Standard H2Option if you want a two-piece design and lower flush volumes, while remembering that you'll need to buy a seat separately.
For chair-height seating in a smaller room, the HOROW HR-ST076WD is the clearest fit in this group. Choose WinZo when a very short projection takes priority and a round bowl works for you.
Before ordering, match the rough-in and full dimensions to your bathroom, then decide which bowl shape and seat height you'll use comfortably every day. See our guide to the best compact toilets if limited floor space is your main concern.

Frequently asked questions
What is a dual flush toilet?
A dual flush toilet gives you two flush choices, usually a lower-volume option for liquid waste and a higher-volume option for solid waste. The exact gallons per flush vary by model.
Compare both settings and the bowl design, then check that the toilet fits your rough-in and bathroom clearances.
Do dual flush toilets save water?
They can reduce water use when you choose the lower-volume flush for suitable waste. Models here range from 0.8/1.6 GPF to 1.1/1.6 GPF, while the American Standard H2Option uses 0.92/1.28 GPF.
Your savings depend on flush choices, household use and the toilet being installed correctly.
Are dual flush toilets hard to use?
Most use two buttons or controls so you can select the lighter or fuller flush. Check the control layout and the instructions for the specific model before installation.
If several people share the bathroom, make sure everyone knows which option to use for each flush.
Can I replace a single-flush toilet with a dual flush toilet?
Yes, if the replacement matches the rough-in and fits the room and plumbing. Many options here specify a 12 in rough-in, so measure from the finished wall to the floor bolts before choosing one.
Our rough-in measuring guide walks through that check.
Is a one-piece or two-piece dual flush toilet better?
A one-piece toilet has a joined tank and bowl, while a two-piece model has separate parts. Choose based on the layout, cleaning access, dimensions and installation needs.
The American Standard H2Option is two-piece and its seat is sold separately.
The other picks here are one-piece models.
