1.TOTO Ultramax II Elongated One-Piece Toilet
If you want to get an excellent toilet no matter the cost, then Toto Ultramax II will probably be the best choice for you. It is rather pricey, but it has some features that aren’t there in the rest of the reviewed toilets.
Ultramax II comes in a one-piece construction with an inbuilt tank. Such a build reduces the number of nooks and crannies in the toilet and allows for easier cleaning. Apart from that, it looks better. This toilet has an ADA-compliant seat height of 17-1/4 inches, which should make it easier to use for people of all ages and those with disabilities.
A remarkable feature of this toilet is its Double Cyclone flushing action, which appears to be the reason behind the toilet’s good performance. Even though this toilet flushes water at a quite moderate rate of 1.28 gallons per flush, it seems to not be lacking even when compared to toilets with more powerful flushing. Aside from that, the lower flush rate makes this toilet quite efficient.
The two nozzles of the Double Cyclone flushing system create a centrifugal action, which is what makes this toilet much more effective in cleaning the rim and the bowl than you might expect. This doesn’t produce much noise though since the toilet isn’t pressurizing the water in its tank.
Ultramax II also features the SanaGloss ionized barrier glazing that is designed to prevent the sticking of debris, mold, and bacteria. The SanaGloss appears to work great, even though it most probably won’t work 100% of the time. Lastly, Ultramax II includes a sturdy toilet seat installed via Toto’s SoftClose system, which is designed to prevent slamming and to allow gentle and quiet lowering.
- Easy-to-clean one-piece construction.
- Soft-closing seat included.
- ADA-compliant height.
- Powerful Double Cyclone flushing action.
- Smooth glazing.
2.TOTO Drake Elongated Bowl and Tank Toilet
In case you want something more affordable, then you might like Toto Drake elongated two-piece toilet. It is a much more affordable yet quite functional a best dual flush toilets.
Toto Drake toilet is a two-piece toilet comprising of a separate bowl and tank. That’s part of the reason for the inexpensiveness of this toilet since two-piece toilets are generally cheaper. However, a two-piece toilet isn’t as seamless as a one-piece toilet. Toto Drake is thereby more difficult to clean as you would also need to think about the nooks between the bowl and the tank. With a rim height of about 15 inches, this toilet will probably be more suitable for shorter people. The rim height, however, makes this toilet, not ADA-compliant, so it isn’t an appropriate choice for people with disabilities.
Toto Drake employs Toto’s G-Max flushing system. With a flow rate of 1.6 gallons per flush, this toilet consumes more water than the Ultramax II. Aside from that, higher water consumption doesn’t necessarily mean that the Drake will be more effective than the Ultramax II since this toilet doesn’t have the Double Cyclone system. Toto Drake probably has roughly the same performance as the Ultramax II but at a higher cost as it consumes more water.
This toilet doesn’t come with any seats, so you would need to go through the hassle of finding the right seat that fits the toilet. The Drake is compatible with Toto’s SoftClose seats, so you could simply go for one if you have the money. And by the way, this toilet is also compatible with Toto WASHLET bidets.
- Fairly inexpensive.
- More suitable for shorter people.
- Quite a powerful flushing.
- Compatible with SoftClose seats and WASHLET bidets.
- It doesn’t come with a seat.
- More difficult to clean.
- The seat height is not ADA-compliant.
3.American Standard H2Option 2-Piece Dual Flush Elongated Toilet
When it comes to efficiency, the American Standard H2Option toilet should be a much better choice than the previous two toilets we reviewed. That’s because this toilet comes with a dual flush system.
The dual flush system of the H2Option toilet does either a full 1.6 GPF flush or a conserving 1 GPF flush. The full flush is excellent for solid waste, whereas the conserving flush is more suitable for liquids. Flushing only as much water as necessary should allow you to greatly save on the water bill in the long run. Another remarkable feature of this toilet is its round design. The H2Option is thereby more compact than the other toilets on the reviews, which makes it a good choice for confined bathrooms. On the other hand, around the toilet doesn’t have as much room as an elongated one. Bear that in mind.
H2Option also features a pressurized rim. The rim chamber of the tank stores the water under pressure. When flushing, the water flow will be much more powerful than in gravity toilets where the flush occurs due to gravity only. And when you add to this the antimicrobial coating of the toilet, you should get a clean toilet at all times. However, while the pressuring could deliver better flushing and scouring capacity, it would probably make the toilet noisier as well.
What could also interest you is that this toilet comes with pre-assembled and factory-installed grommets and bolts. This would, first of all, make the assembly quicker, as well as would probably make the bolts more reliable.
There are a couple of notable downsides in this toilet as well. Firstly, it is a two-piece toilet, so it won’t be very easy to clean. Secondly, it doesn’t come with a toilet seat. Lastly, its rim stands only 15 inches high, which makes it not ADA-compliant.
- More compact round design.
- Two flush modes.
- Pressurized water for power flushing.
- Factory-installed bolts and grommets.
- Has antimicrobial surface.
- It could be less comfortable.
- Slightly noisier.
- Not very easy to clean.
- No seat included.
- The rim is only 15 inches high.
4.TOTO Aquia Dual Flush Elongated Two-Piece Toilet
When it comes to the design, Toto Aquia is the best dual flush toilet that differs slightly from that of the previously reviewed toilets. The thing is that its trap ways are hidden behind an elongated skirt.
The skirt has two good advantages. The first one is that the toilet looks much sleeker than those toilets that do not have skirts. In fact, we think that this toilet is the most good-looking model on the reviews. Secondly, cleanup becomes easier since you won’t have to worry about cleaning the difficult to access nooks of the trap ways. However, because this toilet is a two-piece unit, you will still need to deal with the tiny gap between the tank and the bowl.
In terms of water efficiency, this toilet is quite interesting as well. It does either a full 1.6 GPF flush or a conserving 0.9 GPF flush. The 0.1 gpf difference could make this toilet much more water-efficient in the long run than the other toilets we reviewed. And by the way, this toilet is WaterSense-certified, which attests to its efficiency and environmental friendliness.
The Aquia toilet has an elongated bowl with an ADA-compliant universal rim that is designed to be ergonomic for people of all ages. Aside from that, it should be convenient for use by those who have disabilities. When it comes to downsides, this toilet doesn’t come with a seat, first of all. Secondly, because it has a skirt, the bolts are positioned a little bit differently, meaning that you may need to spend more time or money on the installation.
- Skirted, sleek design.
- Fairly easy to clean.
- Efficient dual flush system.
- ADA-compliant height.
- Might require some drilling for the installation.
- It doesn’t come with a seat.
- Difficult to clean nooks between the tank and the bowl.
5.Woodbridge T-0001 Dual Flush One Piece Toilet
And the last toilet on our reviews of best rated dual flush toilets is Woodbridge T-0001. If you happen to look for a sleek one-piece toilet, then this one could be the right pick for you.
Like Toto Aquia, this toilet features a skirt that covers the trap ways. However, this toilet differs quite a bit from Aquia and basically all the toilets we reviewed in terms of the design. The flatter and edge-rich appearance of this toilet may not be to the taste of everyone, but we can’t deny that this toilet looks very good. If your bathroom appliances have a similar design, the T-0001 would certainly complement them.
Woodbridge includes a pre-installed soft closing seat with this toilet. Aside from smooth closing and comfort, the seat should also be durable and not suffer from looseness thanks to its stainless steel hinge. In addition to the seat, this toilet comes with a wax ring and floor bolts that typically need to be bought separately. This toilet also features a dual 1/1.6 GPF flush system that is WaterSense-certified. Remarkably, the toilet is equipped with a rectangle flush button that should be quite easy to use due to its size.
It also appears that this toilet is rather quiet. It features a glazed flush that allows for quiet and powerful flushing with no clogs or logs, as stated by the manufacturer. The seat height of this toilet is ADA-compliant, so it could be used by almost any individual.
An important benefit for some could be the one-piece design of the toilet. Combined with the skirt, the one-piece build of the toilet makes it quite easy to clean.
- One-piece sleek design.
- Pre-installed soft closing seat.
- Dual flush system.
- ADA-compliant seat height.
- Includes a wax ring and floor bolts.
- Again, will probably require additional expenses for installation.
Dual Flush vs Single Flush Toilets
You might have been wondering what those dual flush toilets are. If you are unsure whether or not they are better, let us explain their benefits over single flush toilets, as well as pinpoint their disadvantages.
The main advantage of dual flush toilets is their water efficiency. In fact, that’s the reason most people choose a dual flush toilet. The thing is that dual flush toilets have two flush modes – full and conserving – whereas single flush toilets always flush at their max. As a result, with a dual flush toilet, you only use the full flush when dealing with solids and most of the time use the conserving flush for liquids.
Because of this, dual flush toilets are considered to be environmentally friendly as they use much less water. That’s certainly a plus if you are concerned about the environment. Secondly, a dual flush toilet could also allow you to significantly cut your water bills, which is a solid reason to choose a dual flush toilet without too much thinking.
Dual flush toilets have downsides as well. Since they are much less common than single flush toilets, the availability of replacement parts leaves much to be desired, not to mention that their price is typically noticeably higher.
Another downside is connected with the button of dual flush toilets. A dual flush toilet has two buttons: one engages the full flush and the other the conserving flush. Typically, the button for the conserving flush is smaller. The issue with this is that it requires greater force for pushing compared to a lever on a single flush toilet, which could become a problem for disabled or elderly persons. This issue also applies to the bigger button but to a lesser extent.
While a dual flush toilet undeniably is superior when it comes to money-saving, it may not be the right choice for you after all. Aside from the price, this is because of the varying availability of replacement parts in different areas. Before making the final choice, make sure that you can find replacement parts in your area. Otherwise, you would probably be better off with a single flush toilet since buying parts for them will most likely be easier and less costly.
