We’ll break down some of the best dual flush toilets in a moment. But first, let’s talk a bit about how dual flush toilets work. Standard fixtures utilize a simple flapper seal and a large water tank. When you flush, the seal will lift up, sending the tank water into the bowl to wash away solid and liquid waste.
How much water you’re using per flush depends on when your standard toilet was made. Toilets made before 1992 tend to use up to 3.5 gallons a flush. If your toilet was made before the 1980s, it could be using as much as 7 gallons! Modern dual flush toilets are much more efficient because they work a bit differently. Let me explain…

From Saniflow is the Sanicompact dual flush toilet. This is a very unique piece of bathroom equipment. It’s purpose-built for basements that can’t rely on gravity alone for flushing.
The cool thing about this toilet is that it has a built-in pump. It’s an electric toilet that’s capable of driving waste up 9 feet to your drainage line. The pump is powerful enough to deliver waste up to 100 feet horizontally as well, making the toilet a great option for those bathrooms that are awkwardly placed.
Thanks to the pump, there are no complaints when it comes to performance. The toilet only uses 1.28 gallons for a full flush and 1 gallon for a light flush. Because the toilet doesn’t use gravity to move waste, there’s no need for a separate water tank. As a result, the toilet is incredibly compact as well.
- 28-gallon full flush, 1-gallon light flush
- Two low-profile flush buttons
- One-piece unit
- Built-in macerator pump
- Available with 12 or 10-inch drain location

If you’re looking to invest in a toilet with a modern twist, check out this dual flush unit from Toto. With its clean lines and low-profile design, this toilet has a unique look that stands out.
The flushing system of this toilet is relatively simple. It uses a traditional dual flush siphon, which is connected to chrome-covered buttons on top of the tank lid. When you use the full flush button, 1.6 gallons of water flow through the bowl. For the lighter option, it uses less than a gallon.
It’s obvious that Toto’s primary concern was saving water. This toilet does not have an advanced cleaning system. It uses the bare minimum to get waste down. Unfortunately, this does leave a lot to be desired when it comes to performance. While it’s efficient for liquid waste, you’re not going to get the same high-powered cleaning performance for solid waste as some of our other recommendations.
- 6-gallon full flush, 0.9-gallon light flush
- Two-piece design
- Chrome push buttons
- Available with 12 or 10-inch drain location
From one of the most prominent bathroom fixture brands in the world is the Wellworth Dual Flush Toilet. Kohler has a pretty solid reputation in the business. With this toilet, the company has managed to create a no-frills toilet that delivers on water efficiency.
Unlike some other options on the market, the technology powering this toilet is very simple. There isn’t a complicated cyclonic flush system or intricate pressurizing feature. Instead, it uses a canister flush valve. The valve is built with durability in mind. It has a long-lasting seal and doesn’t make much contact with the tank water.
Despite its simplicity, the toilet doesn’t disappoint. Kohler designed the bowl for more water contact around the bowl. While it doesn’t always cover every inch of the bowl with the light flush, the full flush does an adequate job of getting rid of waste.
- Two-piece design
- Round seat and bowl
- Lever flush
- 6-gallon full flush, 1.1-gallon light flush
- Dual-Max flushing system - 1.28 Gallon Flush or 0.9 Gallon Flush
With this dual flush toilet from Toto, you’re doing much more than just saving water. You’re also pampering yourself! It’s a unique fixture that has a built-in bidet for ultimate cleaning.
The toilet uses noticeably less water than other WaterSense toilets. For the full flush, it only uses 1.28 gallons of water. It has a Dual-Max Cyclone system. Like the previous model on our list, this toilet delivers water strategically to create a powerful cyclone that washes the sides of the bowl with each flush. Pair that with the SanaGloss glaze and you have a toilet that stays clean longer.
The biggest perk of this toilet is the built-in bidet. There are several great cleaning and drying functions. Not only is it more effective at cleaning your body, but the bidet can help cut back on your toilet paper usage. There’s even a deodorizer, light, and heated seat included for convenience.
- 28-gallon heavy flush, 0.9-gallon light flush
- One-piece unit
- Built-in bidet
- Chrome-plated top mounted push button actuator
American Standard is a well-known brand that’s known for producing some solid home fixtures. The H2Option dual flush toilet isn’t just efficient at saving water. It can even help you keep things clean for much longer.
This toilet has the brand’s H2Option flushing feature. Basically, it’s a fancy name for a dual-flush system. With the heavy flush button, you’re sending 1.6 gallons of water through the bowl. That’s more than enough to take care of up to 1,000 grams of solid waste. With the light flush option, the toilet only uses 1 gallon of water.
From a performance standpoint, the American Standard toilet does very well across the board. The siphon is very powerful. It’s also connected to the PowerWash Rim. The rim of the toilet has its own chamber, which is pressurized with each flush. The water is sent out of strategic holes into the rim to wash away waste from the bowl effectively.
- Elongated toiled
- Chrome-plated buttons
- 12-inch drain measurement
- 6-gallon heavy flush, 1-gallon light flush
