Two-piece toilets are the most common setups around the world – whether it’s in your home or a public restroom at a restaurant. There are many advantages to having these toilets, such as easier transportation to the installation site and the ability to customize the two parts separately.

It is compliant with various international standards, such as ADA, CEC, CALGreen, and WaterSense for its eco-friendly qualities.
Constructed with a universal height, this round two-piece toilet also comes from another well-known bathroom fixture brand.

My premium suggestion is the Toto CST746CSM#51 Drake Two-Piece Elongated Dual Flush Toilet, which has two flow modes: 0.8 and 1.6 GPF, which gives you the choice of water use depending on your needs.

The space-saving design is like having a rounded seat despite being a comfortable elongated bowl. Moreover, it adheres to WaterSense standards in terms of flushing capability to ensure eco-friendliness and savings on your water bill.

A worthy pick for a two-piece toilet seat is the Kohler K-3978-RA-0 Wellworth Elongated 1.6 GPF Toilet, which has a 3-bolt installation setup that reduces hassle on your toilet assembly. The rim height is around 15 inches so it’s suitable for smaller people or if you have children at home.

Toto CST446CEMG#01 Aquia IV Two-Piece Elongated Toilet
Yet another toilet that I like with dual flush capability is the Toto CST446CEMG#01 Aquia IV Two-Piece Elongated Toilet. With this toilet, simply choose between 1.28 GPF and 0.8 GPF for its flow rate, which makes it an eco-friendly and water-saving toilet for budget-conscious people.
When it comes to its technologies, it uses Dynamax Tornado Flush to help clean the toilet bowl in between uses to reduce maintenance hassle.

American Standard 2462100.020 Cadet 2-Piece Elongated Toilet
Made with a 12-inch rough-in, the American Standard 2462100.020 Cadet 2-Piece Elongated Toilet is yet another water-saving fixture at only 1.1 GPF, making it suitable for small homes. With this flow rate, it meets EPA WaterSense standards thanks to its siphon jet flush that’s pressure-assisted.
It has a 2-1/8-inch trapway with a 10 x 12-inch water surface area. Aside from that, it has an EverClean surface (mold-resistant) that’s easy to maintain. For the parts, it comes with two bolt caps for easy installation and a speed-connect tank/bowl coupling system.
The two-piece toilet comes with a trip lever with a chrome metal finish. Made with quality vitreous china, this toilet also has a sanitary dam on the bowl. It has a rim height of 16-1/2 inches so it’s suitable for most residential homes. From the rim to the tank, the toilet spans a length of 29-1/4 inches.
Things I Like About This Product: I like that it doesn’t consume a lot of water since it is only at 1.1 GPF, which is significantly lower than with other two-piece toilets out there. This will be useful for small homes or if you want a water-saving toilet. It also has a mold-resistant EverClean surface for reducing maintenance problems.
Things to Keep in Mind Before Buying This Product: Similar to most toilets, you have to buy the seat separately. Keep in mind that it also doesn’t have a lot of pressure compared to higher GPF toilets so installing a bidet will be tricky.
The Methodology: What I Considered When Picking the Two-Piece Toilets Featured Above
When it comes to two-piece toilets, here’s how I came up with my list of top picks (and you can use this as a buying guide, too!):
Flow rate is expressed in GPF or gallons per flush (or liters per flush, if you use metric). The highest GPF out there in most two-piece toilets is 1.6 GPF, which is already a big change from the traditional 3-GPF toilets of the past.
Really, it depends on your usage and your needs. A higher flow rate means that you have a more efficient flushing capability for difficult waste material. On the other hand, a low flow rate means that you’ll save more water in the long run, but you’ll get less power when it comes to flushing.
A higher flow rate is more recommended for toilets that will be placed in public restrooms and if you have a lot of folks at home – especially kids and seniors. Low flow rates are more ideal for people who live alone or with two to three people.
The mid-range flow rate is around 1.28 GPF as recommended by WaterSense. On the other hand, the lowest flow rate in the market is usually at 1.1 GPF unless you have a dual flush capability for your toilet. We will discuss more water-saving features in the sections below.
The rim height will vary depending on your preferences as well. This height is measured from the bottom of the toilet to the rim.
Common residential homes in the United States typically have 16-inch rim heights and above.
When considering rim height, you have to know about the following:
- Who will use the toilet most often?
- Will kids be using the toilet?
- Do you have seniors at home?
- Which is more comfortable for you: a higher or lower rim height?
If you aren’t that sure, I would suggest going for a 16-inch rim height at most. However, some folks may want a slightly higher rim height, such as with the Kohler K-3658-47 Highline Classic Class Five Comfort Height Toilet, which is at 17 inches or more.
One factor that many household owners consider when purchasing a new toilet is how much water it can save. I prefer dual-flush toilets because you can easily choose between low and high flow depending on the situation, resulting in a balance between flushing power and water savings in the long run.
Dual flush methods work this way: use a light flush for urine and use a heavy flush for much larger waste. An example of a two-piece toilet with a dual flush is the TOTO CST746CSM#51 Drake Two-Piece Elongated Dual Flush Toilet, which is also my premium pick as mentioned above.
Aside from that, it helps if your two-piece toilet has been certified by WaterSense (meets EPA requirements), as well as other governing bodies like the CEC. Certain siphon jets of such toilets are also designed to maximize water flow without wasting too much water.
The PowerWash feature, which is present in the American Standard 211AA.004.222 Champion Pro 1.6 GPF 2-Piece Elongated Toilet (my top pick) and all other American Standard toilets mentioned above are a great cleaning mechanism. What it does is maintain your bowl’s cleanliness with each flush so you don’t have to scrub hard with bleach all the time.
In a way, such cleaning methods found in a two-piece toilet will also help to reduce your use of household chemicals in the long run. This also results in an eco-friendlier toilet in the process.
There are two types of toilet bowl seats: round and elongated. Let’s define each:
Elongated toilet bowls are more comfortable to sit on due to their contoured and narrow shape. The only downside is that they are trickier to install in a small bathroom or space so they are most ideal for bigger homes.
Round toilet bowls are more space-saving in terms of design. However, many people don’t find them as comfortable to sit on as compared to using an elongated toilet bowl.
Whichever toilet bowl type you have depends on your needs – there’s no right or wrong option here. If you want a comfortable seat, go for an elongated toilet. If you have limited space in your bathroom, go for a round toilet.
A two-piece toilet is usually trickier to install compared to a one-piece toilet due to the separate tank. However, lifting it from the curbside delivery to your second floor is much easier due to the two-piece construction and reduced weight.
A good two-piece toilet should have clear instructions, as well as all the necessary hardware for your toilet.
When it comes to measurements, typical two-piece toilets have a 12-inch rough-in. However, some manufacturers may also sell a toilet with a different rough-in (such as 14-inch, 10-inch, etc.) depending on your needs.
Is the trip lever easy to reach? Can you sit comfortably on the toilet? A good toilet to consider should have user convenience. Ease of cleaning, as mentioned above, is also one of such conveniences.
Usually, a two-piece toilet will come in white shade, typically labeled as “cotton.” However, some toilets may also have other colors or styles, such as almond (for warmer-tone bathrooms). Trip levers may come in a chrome finish or the same color as your toilet’s vitreous china.
Durability features will help your toilet to last for a long time. A good example is the Toto CST446CEMG#01 Aquia IV Two-Piece Elongated Toilet, which has a special CEFIONTECT ceramic glazing. This glaze resists different kinds of bacteria, mold, and other harmful microbes that linger in your toilet and bathroom.
The warranty period for most two-piece toilets is between one and five years, depending on the manufacturer or brand. As I reviewed above, the American Standard 211AA.004.222 Champion Pro 1.6 GPF 2-Piece Elongated Toilet, which is my top pick, has a whopping 10-year warranty from the manufacturer.
A longer warranty period helps to put you at ease. Moreover, some toilets also offer a limited lifetime warranty for the chinaware (the toilet itself) and five years on the moving parts. An example is the American Standard 288DA114.020 288DA.114.020 Toilet, which is my budget pick.
Overall, my top choice is the American Standard 211AA.004.222 Champion Pro 1.6 GPF 2-Piece Elongated Toilet, which uses a PowerWash rim and EverClean surface which helps to clean the toilet with each use. I also like the Toto CST243EFR#01 Entrada Two-Piece Round 1.28 GPF Toilet, which is an eco-friendly and water-saving toilet for most households.
If you are on a tight budget, I recommend the American Standard 288DA114.020 288DA.114.020 Toilet, which only has a low flow rate of 1.1 GPF – ideal for smaller homes. My premium pick, on the other hand, is the TOTO CST746CSM#51 Drake Two-Piece Elongated Dual Flush Toilet, which has a dual flush feature that’s also a water-saving function.
Another great consideration that I’d like to suggest is the Kohler K-3978-RA-0 Wellworth Elongated 1.6 GPF Toilet, which is easy to assemble thanks to its DryLock feature. I also like the American Standard 221AA104.222 Colony 2-Piece Elongated Toilet, which has a similar PowerWash rim with my top pick mentioned above.
If you are looking for a high-rim toilet, the Kohler K-3658-47 Highline Classic Class Five Comfort Height Toilet is for you, which is at 17 inches or more. For areas with big mold problems, the Toto CST446CEMG#01 Aquia IV Two-Piece Elongated Toilet has a special CEFIONTECT ceramic glaze with mold-resistant technology. Last but not least: another great low-flow toilet to consider is the American Standard 2462100.020 Cadet 2-Piece Elongated Toilet.
