1. WOODBRIDGE T-0019 Cotton White (Best Overall)

Featuring a heated seat, five water-spray locations and levels, two user memory, and a gorgeous night light, this white cotton toilet by Woodbridge is a state-of-the-art toilet for modern homes!

When it comes to remodeling your washroom, finding out “what is the best dual flush toilet” becomes a number one priority. If you have a big family and live in a cold region, you should definitely check out the T-0019 by Woodbridge.

Not only does it look exquisite in a true cotton white color, but it also offers a bunch of cool specs for comfortable use.

To begin with, you have no less than five spray locations, water heat, and pressure levels. You can greatly benefit from a multifunctional toilet such as this one. In fact, placing it in either a common washroom or your luxurious attached bath will give you the best bang for your buck. 

We particularly liked its energy-saving mode that slays vampire electricity when not in use. Heated water for posterior, pulsating, and feminine wash with adjustable pressure is another reason why we wouldn’t mind spending over four hundred bucks on a toilet!

Besides, who wouldn’t enjoy the warm embrace of a heated toilet seat in biting cold? The water heats up instantly, and you get a remote to control its many features.

Additionally, the high-pressure washing and heating can be toned down for children with the press of a button! To top it all off, the BID01 dries you up with small bursts of warm air after you’re done!

  • Offers multidirectional flushing with different pressure and heat levels
  • Includes remote control to adjust and actuate all the features
  • Comes with an energy-saving mode
  • Satisfactory half-flush and full-flush volumes to prevent clogging the drain pipe
  • None

2. American Standard 2887218.020 H2Option GFP (Best Budget)

With the brand-new EverClean surface that prevents stains and growth of odor-causing mold and mildew, this best flushing toilet by American Standard is our new favorite unit! Coming under 260 dollars, the H2Option is also the budget pick of our choice.

Its siphon bowl technology ensures a high-pressure washing across the toilet bowl. The PowerWash rim offers a satisfying UHET performance for the price. Another reason why H2Option made it to our best dual flush toilet reviews is that its half-flush delivers 0.92 gallons per flush.

However, its full-flush ratings remain similar to those of mid-rage toilets available right now.  Once you properly install the unit, it runs 15 inches from the bottom to the top and approximately 30 inches in length.

Considering its brilliant, reliable water efficiency, the H2Option by American Standard is now approved by WaterSense. This affordable dual-flush toilet also conforms to the MaP PREMIUM standards in every way- swiftly making it to the list of Ultra High-Efficiency Toilets (UHET).

  • Prevents mold and mildew growth around the toilet bowl with EverClean
  • Approved by MaP PREMIUM and WaterSense
  • An ultra-high efficiency toilet that keeps water waste to a minimum
  • The chrome-plated actuator responds quickly
  • You might not have the installation tools close at hand

3. KOHLER K-3987-0 Wellworth Two-Piece Round-Front Toilet

All the round-up reviews on dual flush toilets out there include at least one Kohler toilet for their consistent waste removal, great flush volume, and of course, expensive looks.

It goes without saying, a white cotton toilet with a slim design really seals the deal when you give your guests a proper house tour. While Kohler has, hands down, the best dual flush toilet conversion kit, the price point can be completely bewildering!

That didn’t stop us from pulling the deets on this impeccable Kohler K-3987-0. For starters, it shows off a space-saving, round design at the front, which is perfect for small showering spaces and lavatories. The hand-tripped level is easy to turn for both flush settings.

It measures 29.25 inches from top to bottom and goes 18 inches from side to side. That said, it’s a pretty compact commode, even with two-piece construction.

Moving on, the best dual flush toilet kit by Kohler offers an effective flushing system that leaves the bowl clean every time. Its deep siphon technology is made stronger with a true, gravity-feed construction.

The 2-⅛-inch toilet tramway wasn’t the most pleasing design considering we have already seen a stately Woodbridge. 

Although, we’re still favoring Woodbridge T-0019 over Kohler K-3987-0. The latter doesn’t come with the toilet seat installed, which was a big let-down for us.

  • The compact size is suitable for small to medium bathrooms
  • Its gravity-feed construction allows a noiseless flushing
  • The hand-tripped lever is easy for the lefties to use
  • Heavy-duty waste removal and effective bowl cleaning
  • Doesn’t come with the seat

4. Toto MS920CEMFG#01 1.28-GPF/0.9-GPF Washlet with Integrated Toilet G400

A slow-draining toilet is not only smelly but also looks hideous from the top. Unless you really want to piss off your partner with a flooded toilet, consider getting this Toto toilet to stay on their good side!

For starters, its straightforward design makes it very easy for you to clean the toilet up. You’ll also like the fact that there are no hard-to-reach spots on this dual-flush toilet. It’s because the Toto toilet takes after a sharp, geometric design that elevates your comfort room with a modern look.

An elongated, one-piece toilet with a crazy high flush volume is the one you need, especially after feasting on an insane Thanksgiving dinner or leftover pizza from yesterday.

Lucky for you, this best dual flush toilet kit by Toto releases 1.28 gallons of water per flush- taking down even a stone-hard poo with it. As for the luxurious features of this Washlet bidet toilet, its front and back warm water cleansing is luxury at its finest.

You also have five levels of water pressure and temperature settings on this one. The automatic lid opening and closing is a delight to watch.

And finally, its PreMist and CEFIONTECT function prepares the toilet bowl with fine mist and lubrication. This way, the chances of developing stubborn stains are close to zero!

  • WaterSense-certified, CAL Green-compliant, and ADA-compliant
  • A convenient air deodorizer and dryer
  • The PreMist function sprays warm mist inside the bowl to prevent permanent stains
  • Automatic lid opening and closing
  • Multiple heat settings and water pressure modulation
  • Expensive

5. Swiss Madison Well Made Forever SM-1T254 St. Tropez One Piece Toilet

Consider this gorgeous Swiss Madison toilet the center piece of your comfort room. Have a look at this scintillating masterpiece from this incredible brand. Its fully skirted design and soft-closing seat top it off with an unbelievable price tag.

When you can’t afford a Kohler, Swiss Madison is the way to go for a budget dual-flush motor. Its high-performing gravity flush produces extremely low noise. So, if your washroom is down the hallway, the chances of you waking up to an ear-splitting flush at midnight aren’t there, to begin with.

On a similar note, its soft-closing seat eliminates loud thuds and accidental scratches to the seat. The chrome-hinged seat releases quickly so that you can do some routine clean up in the shortest amount of time. Besides, the flushing strength was quite the surprise for such a low-budget dual-flush motor.

This best dual flush toilet kit from Swiss Madison produces 0.8 or 1.28 gallons of water per flush so that all the wastes go down the sewer. You can teach your kids to flush responsibly on the high mode.

As far as a hassle-free installation goes, the bolts on each side of this Swiss Madison unit are a bit hard to reach. The two holes are quite small to reach all by yourself. After all, lifting a 120-pound toilet to work on the bottom is a two persons’ job.

  • Chrome-hinged seat connectors are easy to remove for clean-ups
  • Its soft-closing seat keeps the exterior free of scratches 
  • Two distinct flush volumes of 0.8 and 1.28 gallons
  • A fully-skirted, space-saving design
  • Might not fit in a tight space between the tub and counter

6. Kohler K-5401-PA-0 Veil Comfort Height Skirted – Intelligent Toilet

Kohler brings you a brilliant dual-flush toilet to make your luxurious dream come true! Its square-shaped, elongated profile beats the looks of our top-favorite Woodbridge T-0019. Additionally, its integrated bidet, lightweight construction, and minimalistic exterior had us sold on this dual-flush unit.

Besides, these Kohler toilets are of the gravity-feed type, meaning that they will flush quietly and effectively at the same time! It was thoughtful of Kohler to make this luxurious toilet just the right level of tall. For example, it allows the users to feel like they are sitting on a nice, comfy chair!

We’ve already said enough about its streamlined, single-piece construction. The fact that you can do without a chunky toilet tank is made possible by its cutting-edge integrated bidet. What’s more, the toilet seat comes included with the Kohler K-5401-PA-0.

Last but not least, you can enjoy a decent 0.8 GPH flushing rate on the half-flush mode and a 1.28 GPF on the full-flush mode.  The auto open-and-close lid, coupled with emergency backup and night light- made it the best dual flush toilet kit from a high-end brand.

  • The integrated bidet makes the unit more streamlined, elegant, and lightweight
  • Offers backup flushing in emergency
  • Includes a night light for better visibility 
  • Its 17-inch tall seat is convenient for elders
  • The toilet trapway is a bit narrow

How do You Choose the Best Dual Flush Toilet?

There are many reasons other than pure aesthetics and luxury as to why you’re looking for the best dual flush toilet kit. It can be the weak flushing strength on your single-flush toilet where the little poos float back up and have an unsolicited pool party in smelly sewage water.

Then there are pressure toilets that do one hell of a job but make a good lot of noise. Below we are listing down the key things you need to consider before remodeling your washroom with the right unit!

Water Consumption

In a way, dual-flush toilets consume less water because you can control the flushing strength as per your necessity. No need to waste about two gallons of water when there is no solid waste to flush out, right?

That said, the best flushing toilet is one that takes the water economy seriously- a dual-flush toilet all the way!

Refill Rates

Low-flush toilets have a slow refill rate compared to full-flush toilets. It means that you need to wait a long time before you can flush the toilet at full throttle. Woodbridge T-0019 not only has a super high flush volume but also refills the tank quietly in a moment.

Moreover, the instant lukewarm to well-heated water sprays from the back and front is a cherry on top.

Waste-Removal Ability

As you’ve already seen from our reviews on dual flush toilets, these products are rated at two GPH ratings. The low setting usually provides around 0.8 gallons per flush, and the high setting maxes out at 1.6 GPH on a good dual-flush toilet.

Bowl Cleaning

Over time, even the best flushing toilet will develop stubborn brown stains that can make your ensuite look like a busy motel washroom. Modern dual-flush toilets offer all-around flushing that rid the bowl of poop stains.

The Kohler K-3987-0 lets you have a choice of 1.1 GPF or 1.6 GPF so that no matter the flush volume, you can have an effective bowl cleaning every time!

Noise Levels

American Standard or Woodbridge is easily one who manufactures the finest dual flush toilet and keeps it within a decent budget. Although, when it comes to a quiet flush, Woodbridge T-0019 does it with excellence.

Dual-flush toilets are naturally the most silent of all toilets. But when it’s one from Woodbridge, you can poo in absolute peace and quiet!

Drain-line Clog

You should have a dual-flush toilet like the Woodbridge T-0019- a reliable commode that doesn’t clog up the drain line. After all, you should be able to poop without thinking about doing the dirty work with a plunger.


There’s hardly a good dual-flush toilet out there that you can bag under 300 dollars. That is why American Standard H2Option was a sweet surprise to us. Toto MS920CEMF, with an astonishing 1.28 GPF, sells for over two thousand dollars for all the right reasons!

However, if you’re willing to settle for a mid-range dual-flush motor, consider Woodbridge T-0019 to be a great pick!


Toilets with one-piece construction and skirted trapway flaunt a space-saving design. These products look exceptionally streamlined. In fact, fully-skirted toilets are very unlikely to get moldy for their simple contours.


Sophisticated dual-flush toilets with adjustable heat levels and air-dry features have a complex layout on the inside. The fact that these toilets’ inner machinery require electricity is also another reason why you need the warranty now more than ever.

Extra Features

This segment comprises the user-friendly specs we found in high-end dual-flush toilets. Multiple water spray locations with gentle pulse and heat are the most desirable features people look for in those expensive toilets. An energy-saving mode and a night light are also great!

Finding replacement parts of your dual-flush toilet like the bolts and flanges is easy when you buy from a reliable brand. Replacement parts of Kohler, American Standard, or Woodbridge dual-flush toilet units are the easiest to find.
