It will help if you keep a balance between the features you need, the brands available in your market, and the budget you have available. Although toilet manufacturers are required to maintain cistern capacities below 1.6 gallons, they can do more. So they get a special permit if they build a toilet with a total of 1.28 gallons or less. However, this is only so if the toilet flushes properly. Some toilets use less water but are less efficient.

10 Best Dual Flush Toilets

Let’s take a look at the best dual flush toilets to think about.

1. TOTO CST746CSMF#51 Drake Two-Piece Elongated Dual Flush Toilet

TOTO CST746CSMF#51 Drake Two-Piece Elongated Dual Flush 1.6 and 0.8 GPF...
  • Newly enhanced design
  • DYNAMAX TORNADO FLUSH utilizes 360 degree cleaning power to reach every part of the bowl
  • Seat Not Included- Must purchase separately
  • Newly designed to provide space savings similar to a round bowl without compromising the comfort of an elongated shape
  • Bowl design reduces water flow resistance and turbulence, resulting in a quieter flush

Toto launched their Drake 2-piece toilet when the EPA first demanded that water use be reduced. It was the most common model on the market, using either 1.6 or 1.28 gallons per flush. It was, however, a single-flush toilet. As an improvement, Toto added the Drake 2-piece Dual Flush. It has multiple features as the single-flush, but it still has some cool extras.

There are fewer nooks and crevices in the bathroom, meaning litter has less space to hide. It has no under-rim, unlike regular toilets, and It has Dynamax Tornado Flush around the bowl instead and ensures efficient waste removal in both light-flush and full-flush systems. Since it is so far from regular toilets, this rimless toilet can be a little perplexing. As the bowl flushes, you may find yourself looking at it, trying to peer under the Youll, the surface that churns the water into a vortex if you look close if you look closely. It’s fascinating to watch.

The toilet is available in white, beige, bone, or black, with extra color. The flushing system can be a bit perplexing. Single-flush toilets have a lever, and most dual-flush toilets have two switches. For both half and full flushes, the Drake 2-piece Dual flush has only one lever. It does a 0.8-gallon half flush if you ‘push’ it back, and you and you will get a perfect 1.6-gallon flush by pulling it against your body. The toilet flush, though, is surprisingly silent in all modes, thanks to its rimless technology. Without the toilet seat, the toilet rises to a comfortable 16.1 inches.

If you like the Drake 2-Piece single flush, you can give the Drake Dual Flush a chance. Its pricing is average, and its tornado flush method guarantees rigorous waste disposal.

  • It comes in five paint options to complement your decor.
  • It’s more discreet than a lot of dual flush toilets.
  • Its ceramic glaze reduces the amount of toilet maintenance needed.
  • A seat, wax ring, bolts, or supply lines are not included with the toilet package. These must be purchased individually, which increases the cost of installation.


2. American Standard 2887216.020 H2Option Dual Flush Toilet

American Standard 2887216.020 H2Option Dual Flush Elongated 1.0/1.6 gpf Toilet,...
  • Chrome-plated top mounted push button actuator
  • 2 color-matched bolt caps
  • EverClean Surface
  • PowerWash Rim scrubs bowl with each flush
  • Siphonic action dual flush combination bowl and tankless seat

The name of American Standard toilets is aptly descriptive. They are ideal for US bathroom measurements due to their elongated shapes and 15-inch height. They use 1.6 gallons for a full flush and just 1 gallon for a semi-flush. Both of these options are WaterSense approved. The rims have a power-wash feature to make flushing even more convenient. By hitting the bowl with high-pressure water, it adds extra scrubbing capacity. On the inside and outside of the toilet, the bowl has proprietary EverClean glazing.

There is no impurity stick to the inner toilet surface, thanks to this glaze. It also guards against dust, dirt, mildew, mold, fungi, toilet residue, and other bathroom spills on the outside. You won’t need to be concerned if your make-up or bathroom cleaners spill into your spotless toilet. Experiment with your model if you’re uncertain about the glaze consistency. It has been stated that it can tolerate everyday usage for up to 6 months without a toilet cleaner that makes going to the bathroom a lot easier. It’s almost effortless to clean, and it saves soap as well!

Unlike traditional toilets, H2Option has a broader surface area. It ensures that the power washer would have more time and space to deal with. It adds extra momentum to the flushing water, making the flushing pressure more powerful. The chrome-coated dual-flush buttons are designed to survive repeated clicking. The toilet has a sanitary dam for additional sanitation, and the EverClean glaze extends beyond the bowl. It reaches down to the trap, meaning that even the areas of the plumbing that aren’t visible are germ-free. The toilet has earned a MaP (Maximum Performance) ranking.

It means that a full flush will remove 1,000g of waste, while a half-flush can remove 400g. The toilet flushes use a pressurized siphon system, which uses 37.5% to 25% less water than standard toilets. The rim shoots water jets while the bowl siphon draws it in. This push-and-pull operation works together to provide improved flushing by consuming less water overall. The toilet seat, on the other hand, is sold individually, so keep that in mind. Push-button flushers are often more difficult to patch in the event of clogs and breakdowns than lever flushers.

Buy this American Standard H2Option if you want assured water protection and a 5-year warranty. It installs quicker because it only has two bolt connectors and fewer moving parts.

  • At the top of the cistern, there are two easy flush keys.
  • It has a 12-inch rough-in, making it ideal for standard-sized bathrooms.
  • For enhanced aesthetics, it is available in pure white, bone, or linen tone.
  • This two-piece toilet is delivered in two halves. That is, it has two different boxes with different arrival dates on the occasion that will cause your installation schedule to be slowed.


3. Woodbridge T-0020 Dual Flush Elongated One Piece Toilet

WoodBridge T-0020 Dual Flush Elongated One Piece Toilet with Soft Closing Seat,...
  • Deluxe Modern Design: Clean, sleek, and complimenting with different styles
  • Toilet dimensions – 28" L x 15" W x 29" H | Weight – 138 lbs. | Rough-In – Standard 12” | Seating height – 15 ¾” | Size – 1.28 gallon flush
  • Siphon flushing design - fully glazed flush, bringing super quiet & powerful flushing - no clogs, no leaks
  • Comes with stainless steel durable seat hinge, unlike other toilet seats that damaged easily, and comfort height design
  • The skirted trap way creates a sleek look and makes cleaning easier, comparing to other toilets. It has no corner and groove

If you prefer straight lines to curves, the Woodbridge T-0020 will appeal to you. With a square seat and a cube-like shape, it’s a cute, lightweight toilet. There are more minor sides and corners for mud and dampness to cover since it is a one-piece with a skirted trap. The toilet appears to be thin, but it is not. Its compact shape makes it ideal for small bathrooms, but its dimensions are full-size. The toilet is 27.75 inches from the wall and has a smaller cistern. From seat bolt to bottom, the toilet is 18.5 inches long and 15 inches tall.

It indicates that the toilet seat is the standard size for elongated toilets, even though its form necessitates a custom seat. The slow-closing toilet seat, fortunately, is included. Since the lid is made of the same vitreous solid china as the rest of the toilet, this protection function is essential. The T-0020 stands 16.5 inches tall and is fixed in place by a stainless steel hinge. It includes all of the necessary parts and materials for assembly, including a wrench, nuts, and a wax ring. Since the toilet flushes with siphon pressure, it is less likely to clog or spill.

Since the siphon system suckers waste into the trap while the rim and cistern discharge water, this is the case. The toilet load is pulled straight through in a rigorous but quieter manner with this double power. You can install a heated bidet mode for wet washing if you like. This toilet is both attractive and environmentally friendly. The design makes for a vital conversation starter. It also successfully supports people of all heights, weights, and genders, including its diminutive size.

  • Its elegant, modern architecture brings a splash of style to every bathroom.
  • It’s easy to clean because of the clean lines, matte glaze, and skirted bottom.
  • It is WaterSense compatible since it uses 1 gallon of liquid flush and 1.6 gallons of solid color.
  • None


4. Toto MS970CEMFG#01 1.28-GPF/0.9-GPF Washlet with Integrated Toilet

Toto MS970CEMFG#01 1.28-GPF/0.9-GPF Washlet with Integrated Toilet G500, Cotton
  • Dual-Max flushing system - 1.28 Gallon Flush or 0.9 Gallon Flush
  • Front and rear warm water washing with temperature and adjustable pressure controls
  • Remote control operation. Illuminated touch pad. 2 user memory. Auto Open/Close lid. Auto Flush
  • Sleek, low profile skirted one-piece Elongated front bowl
  • Automatic air deodorizer - Warm air dryer

This Toto Washlet is a prime illustration of how technology is infiltrating every aspect of our lives. Wet wash bathrooms were once associated with a particular culture. However, a growing number of people are adopting this practice, both for hygiene and to eliminate (toilet) paper waste. The Toto Washlet is a bidet-style toilet with a strong flush of 1.28 gallons and a liquid flush of 0.9 gallons. Since the toilet flushes itself depending on your use and load, you don’t have to pick which way to wash. The cover also opens and shuts on its own.

It’s an actual valet experience, and you can have a rear and front wash with hot water and a built-in dryer if you like. There’s also a deodorizer in there to keep the bathroom smelling fresh. The toilet has a streamlined one-piece frame and a modern conical skirt. You may also use the remote to control the toilet and program two separate settings for your master en-suite.

The Toto Washlet’s toilet seat is elongated. The bowl is covered with SanaGloss glazing to keep it clean, and it flushes using a gravity-based cyclone mechanism. The toilet seat can also be heated. However, the toilet is pricey, so start saving now if you’re able to pay for all the extra toys. It seems frail, but it will accommodate people up to 6 feet tall and 300 pounds.

  • The high-tech features make it perfect for gadget enthusiasts.
  • It’s ideal for winter because of the warm bath, electric dryer, and heated bench.
  • Its unique style adds to the sophistication of your bathroom.
  • Since almost all of its functions are automatic and electric, it can reduce your flushing costs while increasing your energy consumption.


5. Swiss Madison Well Made Forever SM-1T106 Concorde One Piece Toilet

Swiss Madison Well Made Forever SM-1T106 Concorde One Piece Toilet, Glossy White
  • Dual flush with high-performance gravity 0.8/1.28 gallon per flush (gpf)
  • Seamless porcelain one-piece with an easy-to-clean design.
  • Square bowl offers added room and comfort.
  • Soft Closing Seat closes gently and quietly.
  • Quick-Release seat can be unlatched from the toilet for easy removal and convenient cleaning; no tools required.

All of us equate the Swiss with superior elegance and clean architecture. Both boxes are checked in this bathroom. It’s a simple one-piece with soft curves and easy-to-clean surfaces. It has a sharp and elegant square shape with rounded corners, so it also has a linear look.

The toilet seat unlatches with a simple snap and push-button removal, making cleaning much more accessible. It is not enough to pry or unscrew the seat. It isn’t to say the toilet seat isn’t sturdy. It’s made of durable ceramics and features a slow closing seat to prevent cracks, slams, and accidents. Since it only uses 1.28 gallons for a ‘big flush’ and 0.8 gallons for a ‘little flush,’ this toilet complies with California regulations. The flush buttons are white with chrome trim and rest on top of the small toilet tank. Its trap is hidden in plain sight and saves room.

The toilet has a skirted style and a distinctive outline at the foot. It’s a bold declaration item that’s also low maintenance. It often doesn’t need power until you install a bidet. However, since it is an import, you must ensure that they can supply (replacement parts) to your site. Incompatibility is a problem for personalized toilet seats. This one is attractive, but its square shape is unsuitable for women with narrow hips. You won’t be able to order individual toilet seats if it is destroyed. Overall, the chairs are much too delicate and cumbersome to be shipped separately.

This toilet is ideal for a secondary bathroom that isn’t used much. Because of its minimalist architecture, it requires little maintenance, especially on its outer surfaces. Just make sure you don’t crack it.

  • It has a contemporary aesthetic that is appealing, particularly for a house with an artsy or industrial theme.
  • Plus-sized homeowners can appreciate the big seat and solid construction.
  • It has a 1.28-gallon heavy-flush tank, which is smaller than the standard 1.6-gallon cap.
  • Waiting for substitutes – or even original arrival – as a vulnerable manufactured commodity may be aggravating.

10. TOTO AQUIA IV 2PC Connect+ W/ SS124 1.28GPF Cotton

Overall, the best dual flush toilets are generally judged on these factors, as shown in the American Standard H2Option. It not only comes at an incredible price, but many customers who have made checked transactions have stated in their reports that the H2Option eliminates wastes, whether using the full flush or half flush method.

It also has a beautiful nature and an extra siphon jet, which boosts the flushing system and more effective water conservation.

If you care for the environment, look for a toilet that has earned this EPA certification. EPA WaterSense is the name of this certification. It mandates that the bathroom use no more than 80% of the EPA’s norm (1.6 gallons).  Few toilets on the market use as little as 0.8 gallons per flush, but two to three colors are used to remove toilet waste thoroughly. Look for a hardware store that will make you try something out before you buy it. It is critical because the additional flushes could wipe out any water savings.
