With literally hundreds of different toilets to choose from, we have selected the best flushing toilets available. When arriving at our choice we have included toilets that are EPA Water Sense certified, ADA-approved rounded bowls, and elongated bowls. We have also included dual flush as well as single flush toilets.
One of the requirements of ADA approval is a height from the floor to the seat. This height is designed so that it is comfortable to use for the majority of adults when they sit and stand. However, the height is less comfortable for children and people who have a less-than-average height. To compensate for this, included in our selection are some ‘regular’ height toilets.
In the selection below, we have detailed brief details on the toilets. For full details and specifications, follow the link at the end of each short review to take you to the full detailed review.
5 Top Flushing Toilets
1 – Niagara Stealth 0.8 GPF Toilet with Round Bowl
The Niagara Stealth Toilet is really the ultimate in a water-conserving toilet. It uses just 0.8 gallons per full flush. Niagara claims that a very highly efficient flushing system thoroughly clears the bowl on the first flush every time. So, there is no need to use a double flush. Although this is a very technologically advanced toilet, it looks very much like many other similar two-piece toilets.
Not only does this toilet use just 0.8 gallons of water on a full flush but it is also very quiet at the same time. Toilets that meet the Water Sense certification (1.28 GPF) are classed as HET (high-efficiency toilets). Niagara Stealth is the only toilet that is classed as a U-HET (Ultra-high efficiency toilet). Its flush efficiency is increased by the addition of an air channel between the waste pipe and the cistern. When the toilet is flushed the air pressure differential causes the waste pipe to act as a siphon to help draw the waste down the pipe with a greater force.
2 – KOHLER Wellworth Two-Piece Toilet
The fact that the toilet is a little smaller does not reduce its efficiency of the toilet. The Kohler Wellworth toilet has a Class 5 flush system. It can also remove a large quantity of waste in just one flush and still meet the EPA Water Sense specifications for low water consumption.
Kohler’s class 5 toilets are renowned for the amount of waste that they can flush away in a single flush, even with only 1.28 gallons of water. The dual flush system delivers a full flush of 1.28 gallons or a partial flush of 1.1 gallons.
3 – KOHLER Gabrielle Toilet
The Kohler Gabrielle K-3615-0 Comfort Height One-Piece Elongated 1.28 GPF Toilet with AquaPiston Flush Technology and Left-Hand Trip Lever in White is an ADA-compliant toilet. It has an elongated bowl, thanks to some clever design with the tank. Kohler Gabrielle takes up no more space than a rounded front toilet does. This makes it an ideal option for fitting in smaller bathrooms as well as powder rooms. The toilet comes complete with a quiet close seat and lid, as well as a trip lever.
Gabrielle’s cleaning efficiency comes from a combination of the power of the AquaPiston flushing. It has the method that the water enters the bowl and the design of the shape of the bowl. Also, Kohler Gabrielle has a fully glazed trap way. The toilet will clean even a large amount of waste completely on a single flush. Externally, the smooth curves of the toilet prevent any hard-to-reach places where dirt can accumulate. The toilet does not have any special coatings in the bow. So, almost any standard toilet cleaning agent can be used for cleaning.
The Gabrielle toilet uses only 1.28 gallons of water for a full flush. This low water consumption combined with the ability to remove a large volume of waste gives this toilet an EPA Water Sense certification.
4 – American Standard Champion 4 Toilet
The American Standard Champion 4 is manufactured in vitreous china and has American Standard’s Ever Clean surface. This surface finish inhibits stains and the growth of bacteria, mold, and mildew, keeping the toilet cleaner for longer. The 1.6 gallons per flush uses the Champion 4 flushing system for a 4” high-pressure piston to give a high-performance flush.
This toilet has an elongated bowl and a rim height of 16 1/2”. When the toilet is fitted with an appropriate height seat (which must be purchased separately), the toilet becomes ADA-compliant.
The 1.6 gallons per flush ensures that this toilet is within Federal toilet flush specifications. However, the 1.6 GPF means that it is outside the Water Sense guidelines and does not qualify for rebates.
5 – American Standard H2Option Toilet
H2Option has a dual flush system using 1.6 GPF for the full flush and 1.0 GPF for the partial flush. The flush is operated by two chrome-plated push buttons on the top of the tank. Its flushing action is enhanced by American Standard’s H2Option Siphonic flushing system. That means it is a high-efficiency pressurized flushing action. Even though the full flush uses more than the general Water Sense specification of 1.28 GPF, as this is a dual flush toilet the testing is different. The test is based on the average of two partial flushes and one full flush. This compact toilet meets these specifications and therefore, is Water Sense certified. American Standard H2Option toilet is not ADA-compliant. The toilet, which is 100% flush tested before leaving the factory, carries a 5-year limited warranty.
Water Saving Toilets
As early as 1988 low capacity flush toilets of 1.6 gallons were mandated in Massachusetts for all new buildings and remodels. Part of the Energy Policy Act of 1992 was mandated that all toilets installed for new builds and remodels in private houses from 1 January 1994. Toilets installed anywhere in the US after 1 January 1997 should have a flush capacity of no more than 1.6 gallons per flush.
In 2006, the EPA Water Sense initiative was introduced. This was a system whereby toilets that use less than 80% of the federal 1.6 gallons per flush would be certified as Water Sense toilets.
Although the EPA Water Sense certification is a federal initiative, the incentives for such toilets are not universal across the whole of the US. In many municipalities buying a WaterSense-certified toilet will entitle you to a rebate. The areas that do offer rebates are available on the EPA Water Sense website. You can check out your eligibility by following this link.
Although the Water Sense certification is voluntary in most regions, there are some states and municipalities that have their own regulations. For example, in Los Angeles, ordinance 180822, sec 125.03 states
Note; for dual flush toilets, the 1.28 GPF is an average consumption of 1 full flush and two partial flushes. This allows dual flush toilets with a 1.6 gallon per the main flush as long as the partial flush volume takes the average to 1.28 GPF or below.
To fit a toilet into a new or refurbish restroom for employees or the public’s use, the toilet must be ADA-certified. In brief, this requirement means that the toilet seat must be of a certain height from the floor. This height requirement is to make sitting and standing from the seat comfortable for most adults. The shape of the bowl must be of an elongated design and the flush mechanism must be lever operated. Additionally, the lever must be on the approach side of the toilet.
These ADA requirements exclude all round toilets and toilets with push-button flushes. Many of the toilets on the list above do meet some of the specifications, in that they do have the ADA-required seat height. While this height is good for adults it can be a little high for children. Check out our full reviews to see the exact specifications heights and shapes of toilet bowls for each toilet.
