Top 5 of the Best Dual Flush Toilets – 2021 Reviews
- TOTO Aquia IV WASHLET Elongated Dual Flush
- American Standard H2Option Siphonic Dual Flush
- HOROW Compact Dual Flush Toilet
- WoodBridge Dual Flush Elongated One Piece Toilet
- WOODBRIDGE, T-0032 Elongated Toilet
If you are looking for a two-piece toilet (where the cistern and the bowl are separate) that is both dual flush AND water-saving, then the TOTO Aquia is worth looking at. This toilet has different technology from your standard toilet and works with a DYNAMAX TORNADO FLUSH. This is where instead of the water flushing downwards through the pan, it flushes around the pan in a swirling motion and thereby capturing 100% of the bowl. This makes your toilet cleaner and safer but without using any additional water than a standard system.
The dual flush with the TOTO Aquia only uses 0.8 gallons per flush on a small flush and 1.28 gallons per flush on a larger flush (a standard single flush toilet uses 1.6 gallons). This saves you, on average, an astonishing 10 gallons of water every single day of use! That’s 40% less water used without any adverse effects.
All TOTO toilets are coated with a special Cefiontect coating, which is designed to make the surface of the bowl smoother and, therefore, easier to clean. This ion-infused glaze seals any microscopic gaps where germs would normally hide and also helps the water to flush more efficiently.
With a choice of heights (410mm or 394mm from floor to rim) and a beautifully sleek design, this TOTO Aquia is not just great for saving water but also very stylish. The toilet comes with everything you could need to install it, including the hardware, seat, wax ring, and full assembly instructions.
A good all-rounder, the American Standard is one of the most popular toilets across the country, and for a good reason. This dual flush option provides both a classic design and a water-saving capacity. Each flush uses 0.92 gallons per flush for the smaller flush and 1.28 gallons per flush on the more significant flushes, making it so water efficient that it is water sense certified. The bowl itself uses siphon jet technology that is both efficient and hygienic while the trap is fully glazed to make a smoother transition for waste to pass through.
This classic design comes in three different colors, which are white, linen, and bone. The chrome flush button is clearly marked with raised dots so you can determine which sized flush to use. The bowl itself contains all of the waste pipes, so you don’t have to fiddle with additional ones when you are installing it. Overall, this is one of the easier two-piece toilets to install and should only take an hour.
If you need to fit a toilet into a tight space and you are looking for one that will suit a modern style, then the HOROW ticks all the boxes. This compact, stylish toilet might be small, but it still provides you with perfect flushing and waster saving capabilities. The siphon flush technology that uses only 1.1 gallons per flush on a small flush and 1.6 gallons per flush on a large one, cleans the bowl easily and powerfully pushes any waste through. The glazed surface means no germs can lurk and grow in any cracks or crevices.
This toilet is a one-piece system (the others in our list so far have been two-piece), which means that it is a complete unit. This unit is floor mounted, and as such, you need to ensure that where you are fitting it is capable of taking the whole weight and that you have something solid to drill into underneath the screws. The water line is also not a standard 7/8,” but it does come with an adapter, so this shouldn’t be a problem.
The design itself is a modern look with sleek, sharp edges and a chrome button flush. The toilet seat is a soft close seat, and the trap way is wider than an average of 2 inches wide (thereby reducing the number of blockages). Combining all of this into one compact toilet and you have a highly efficient yet small and stylish toilet for your new bathroom makeover.
The Woodbridge is another one-piece toilet that is certainly unique in design. This ultra-modern toilet is boxy and square in appearance, but don’t let that fool you on its capabilities. While this toilet is of a standard height, it does protrude out further than some others at nearly 28 inches, so we recommend that you measure your bathroom carefully before committing to this ultra-modern style toilet. It is worth noting that while it is square in appearance, there are no actual corners or sharp angles WITHIN the toilet, and as such, you get performance.
Available in both white and black, this dual flush toilet with soft closing seat uses only 1 gallon per flush for the smaller flush and 1.6 gallons per flush for the larger one. As with the others, it is fully glazed inside, and this helps to keep germs at bay and prevents and resistance for the water when it is flushing. All of the traps and pipes are concealed within the unit itself, making it not only look clean-lined but also easier to keep clean!
Because this is an all-in-one unit, it is really easy to install and comes with all of the hardware you could need. This Water Sense certified toilet might be tailored to those with a unique taste, but it really would make an impact on anyone who uses it!
If you like the sound of the Woodbridge Toilet but aren’t sure that the sleek square design will suit your bathroom, then you might prefer the elongated version. With more sweeping curves, this toilet still provides all of the technology and capability but with a slightly more classic design. Still comprising of a single unit, this toilet is also Water Sense Certified and will save you both money and save water too. Each flush uses 1 gallon of water per flush on the smaller flushes and 1.6 gallons per flush on the larger one, matching its squarer counterpart.
Because of the one-piece design, this toilet has fewer components to go wrong on it and is less likely to leak. This is thanks to the single molding with all of the trap ways and pipes within the system. This also makes it much easier to clean on the outside as well. The interior of the bowl is glazed for reduced friction and a smoother finish. The chrome flush buttons are easy to keep clean and allow you to choose between a small or large flush easily.
This toilet also comes with a soft closing seat and stainless steel hinges, which are ideal for keeping germs at bay. Every part of the Woodbridge has been considered when designing this toilet, and it really shows in the craftsmanship and detail in each individual piece.
When you think about purchasing a toilet, you might just think that you need to replace what is already there.
But in actual fact, a lot of houses and apartments that are over 20 years old will have outdated toilets in them that consume too much water.
Water-saving is a hot topic right now, and so it is really important that you try and upgrade your toilet to fit these requirements.
Here are all of the toilets explained:
A single flush toilet describes a cistern that only has one unit of water that is pushed through to remove waste (i.e., when it is flushing).
This system is fine for single households and for commercial units.
But bear in mind…
This system will use more water than required for some tasks and that will show on your water bill.
These toilets are cheaper than most, and that is down to the fact that you end up spending more on your water bill.
You will still be able to fund a variety of designs and styles through which will cater to everyone’s needs.
A dual flush system works by using a smaller amount of water or a more significant amount of water to flush, depending on which button you push.
The smaller amount of water is designed to easily flush away liquid waste, while a larger amount of water is designed to flush away solid waste.
This optional flush system means you save much more water than a single flush system, assuming it is used correctly.
Dual flush systems come in a wider variety of designs and styles, including one-piece units, two-piece units, and hidden cistern units.
Depending on the style of your bathroom will depend on your preferred design, so it is vital to think through your room design before you commit to purchasing.
Some water-saving systems come in both single and dual flush capacities.
They work by reducing the amount of water in each flush to as little as possible to perform the task.
Depending on how much you want to spend, these systems are pretty effective.
But if you want a toilet that is guaranteed to flush your waste every time, then a dual flush system is a much better fit for you.
These toilets are quite new in technology and are a lifesaver for people who don’t want to spend out on having pipes moved.
They are independently plumbed toilets that can be situated in places of your home that don’t have a waste pipe.
Best of all!
These toilets will macerate any waste and send it via your water outlets (i.e., wastewater for your sinks) instead. This makes converting a downstairs closet or installing an en-suite easy peasy.
A word of caution…
… these systems are not easy to install yourself and will need a qualified plumber to fit. This can add to the cost and could offset any money saved from not having to move the pipes.
However, they’re mostly available from specialist suppliers who can also make them more expensive.
If you want to install a new bathroom where you don’t have any pipes and don’t have unlimited funds, then you might want to consider a portable toilet instead.
Portable toilets have come on leaps and bounds in terms of technology.
You can actually find portable toilets that are as effective, if not more, than some household toilets.
Portable toilets have become popular for pool houses, guest suites, and even in homes, thanks to them being so sturdy and effective!
They come in a range of sizes and designs, from your most basic bucket design to a seriously complex electric flushing system.
Some are designed so well that you wouldn’t even be able to tell that they are portable at all!
