Buying Guide: How to Choose the Best Dual Flush Toilet for Water Savings
So you’re thinking about getting one of the best dual flush toilets for water savings. Smart move. It’s one of the easiest home upgrades to cut your water bill and help the environment. But not all dual flush models are created equal. I’ve installed a few and learned what separates the good from the great. Here’s what I look for.
First, let’s talk about the flush mechanism itself. You’ll see two main types: push-button and lever. Push-button is common on one-piece toilets and often has two buttons—a smaller one for liquid waste (around 0.8 to 1.1 gallons per flush) and a larger one for solid waste (around 1.28 to 1.6 gallons). Levers usually work by pushing up for a light flush and down for a full flush. I personally prefer a well-labeled push-button system; it’s more intuitive for guests and harder to accidentally trigger the wrong flush.
Performance is non-negotiable. A water-saving toilet that needs a second flush isn’t saving anything. Look for terms like “fully glazed trapway” and “power flush” or “pressure-assisted” technology. A wider, fully glazed trapway (the channel that waste travels through) prevents clogs and helps everything move smoothly. Pressure-assisted models use air pressure to create a stronger, more effective flush, but they can be louder and more expensive. Gravity-fed models have come a long way and are usually quieter.
Then there’s the toilet shape and rough-in. Elongated bowls are generally more comfortable for adults, while round bowls save a few inches of space, which is key for small bathrooms. The rough-in is the distance from the wall to the center of the drainpipe. 12 inches is standard, but always measure your old toilet before buying. Getting this wrong is a huge headache.
Finally, consider the build. One-piece toilets have a seamless tank and bowl, making them sleek and easier to clean, but they’re heavier and pricier. Two-piece toilets (tank and bowl separate) are the classic style, often more affordable, and easier to transport. Check the material quality—a vitreous china finish resists stains and scratches much better.
My last piece of advice? Read reviews, especially about real-world performance and ease of installation. A toilet is a long-term investment, so taking the time to pick the right one pays off every single month on your utility bill.
Frequently Asked Questions
How much water can I actually save with a dual flush toilet?
A lot. Replacing an older toilet (which can use 3.5 to 7 gallons per flush) with a modern dual flush model is one of the biggest water-saving changes you can make at home. On average, a person flushes about five times a day. If most of those are liquid waste flushes (using about 0.8-1.1 gallons), you’re saving gallons compared to a standard 1.6-gallon single-flush toilet every single day. For a family of four, this can easily add up to thousands of gallons saved per year, which is great for both your wallet and the planet.
Are dual flush toilets harder to install or repair?
Not really. Installing a dual flush toilet is essentially the same process as installing any other two-piece or one-piece toilet. The mechanism inside the tank is different, but it’s not more complex. Many use a simple drop valve system. As for repairs, the most common issues are with the flush valve or fill valve seals, which are standard and easy to find at any hardware store. The dual flush buttons or levers are usually sold as a complete kit, making replacement straightforward if needed.
Do they clog more easily because they use less water?
This is a common worry, but a well-designed model should not. The key is in the engineering. Many of the best dual flush toilets for water savings are designed with larger trapways and use improved bowl design to create a more effective siphon and “wash down” with less water. I always recommend looking at reviews that specifically mention flushing power and reliability to avoid a model that has a reputation for clogging.
What’s the difference between a gravity-fed and pressure-assisted dual flush toilet?
Gravity-fed toilets use the weight of the water in the tank to create flushing force—it’s simple, quiet, and the most common type. Pressure-assisted toilets have a sealed inner tank inside the main tank that uses your home’s water line pressure to compress air. When you flush, this pressurized air forces water into the bowl with more power. They are excellent for preventing clogs and have a very strong flush, but they are noticeably louder and typically cost more.
Is a one-piece or two-piece dual flush toilet better?
This comes down to your priorities. A one-piece toilet has a seamless design that looks more modern and is significantly easier to clean because there’s no gap between the tank and bowl. They tend to be more expensive. A two-piece toilet (the classic separate tank and bowl) is almost always less expensive, and the separate parts make it easier to handle and transport, especially if you have narrow doorways or stairs. Both types can be equally efficient.
